2 PRODUCT DESCRIPTION

2.1 Introduction

YORK YAES chillers are designed for water orwater-glycol cooling. There are two product families,standard and high efficiency, an optional low soundversion is available for both the standard and highefficiency models. All units are designed to be locatedoutside on the roof of a building or at ground level.

The unit consists of two screw compressors, one ineach of two separate refrigerant circuits, a single shelland tube DX evaporator, air cooled condensers andthermostatic expansion valves.

The units are completely assembled with allinterconnecting refrigerant piping and internal wiring,ready for field installation.

Before delivery, the unit is pressure tested, evacuated,and fully charged with refrigerant and oil in each of theindependent refrigerant circuits. After assembly, anoperational test is performed with water flowing throughthe evaporator to ensure that each refrigerant circuitoperates correctly.

The unit structure is manufactured from heavy gauge,galvanised steel and coated with “Desert Sand”(RAL 1019) baked-on enamel powder paint.

2.2 Compressor

Twin helical semi-hermetic screw compressors, areprovided to ensure high operational efficiencies andreliable performance. Capacity control is achievedthrough a single slide valve. The compressor is apositive displacement type characterised by twohelically grooved rotors which are manufactured fromforged steel. The 50 Hz motor operates at 2950 rpm todirect drive the male rotor which in turn drives the femalerotor on a light film of oil.

Each compressor is direct drive, semi-hermetic, rotarytwin screw type and includes the following items:

Two screw rotors, with asymmetr ic prof i les,manufactured from forged steel.

A cast iron compressor housing precision machined toprovide optimal clearance for the rotors.

An internal discharge check valve to prevent rotorbackspin during shutdown.

An acoustically tuned, internal discharge muffler tominimise noise, whilst optimising flow for maximumperformance.

Discharge shut-off service valves (with optional suctionshut-off valves).

A reliable suction gas cooled high efficiency, accessiblehermetic motor with redundant overload protectionusing both thermistor and current overload protection.

A suction gas screen and serviceable, 0.5 micron fullflow oil filter within the compressor housing.

Refrigerant gas is injected into the void created by theunmeshing of the five lobed male and seven lobedfemale rotor. Further meshing of the rotors closes therotor threads to the suction port and progressivelycompresses the gas in an axial direction to thedischarge port. The gas is compressed in volume andincreased in pressure before exiting at a designedvolume at the discharge end of the rotor casing. Sincethe intake and discharge cycles overlap, a resultingsmooth flow of gas is maintained.

The rotors are housed in a cast iron compressorhousing precision machined to provide optimalclearances for the rotors. Contact between the male andfemale rotor is primarily rolling on a contact band oneach of the rotor’s pitch circle. This results in virtually norotor wear and increased reliability.

The compressor incorporates a complete anti-frictionbearing design for reduced power input and increasedreliability. Four separated, cylindrical, roller bearings(50000 hours L10 life under design conditions) handleradial loads. Angular-contact ball bearings handle axialloads. Together they maintain accurate rotor positioningat all pressure ratios, thereby minimising leakage andmaintaining efficiency. A springless check valve isinstalled in the compressor discharge housing toprevent compressor rotor backspin due to systemrefrigerant pressure gradients during shutdown.

Motor cooling is provided by suction gas from theevaporator flowing across the motor.

The compressor is lubricated by removing oil from therefrigerant using an external oil separator. Thepressurised oil is then cooled in the condenser coils andpiped back to the compressor for lubrication. Thecompressor design working pressure is 31 bar(450 PSIG).

A 350 watt (230 V 1 Ø 50 Hz) immersion heater islocated in the compressor. The heater is temperatureactivated to prevent refrigerant condensation.

Motor Starting

Two types of compressor motor starting are available:star/delta open transition starter and optional star/deltaclosed transition starter.

The standard star/delta starter utilises 3 motorcontactors and a transition delay relay. The optionalclosed Star/Delta starter utilises 4 motor contactors, aset of transition resistors and a transition delay relay.The star/delta start allows inrush current to be limited toapproximately 33% LRA with the closed transitionoption reducing the transitent star to delta current.

(02/05)

2-2 035L02519-100 Rev. 1

INTERNAL PILOTOPERATED OILRETURN CHECK VALVE

When the microprocessor initiates a start signal to run acompressor, it runs in star for 4 to 10 secondsdepending upon motor current as sensed by themicroprocessor. Normally, the transition to delta takes10 seconds if current is below 125% FLA. If motorcurrent exceeds 125% FLA, the transition is made todelta after a star run time of at least 4 seconds.

Capacity Control

The compressors will start at the minimum load positionand provide a capacity control range from 20% to 100%per compressor using a continuous function slide valve.The microprocessor controlled output pressureregulating capacity control valve will commandcompressor capacity independent of control valve inputpressure and balance the compressor capacity with thecooling load.

The automatic spring return of the capacity control valveto the minimum load position will ensure compressorstarting at minimum motor load.

2.3 Oil Separator

Each circuit has a high efficiency, augmented gasimpingement type oil separator to maximise oilextraction without fragile media to break down.

The oil separator, is mounted in the discharge line of thecompressor. The high pressure discharge gas is forcedaround a 90 degree bend. Oil is forced to the outside ofthe separator through centrifugal action and capturedon wire mesh where it drains to the bottom of the oilseparator and passes to the oil cooler section of thecondenser coil where it is cooled before it returns to thecompressor.

The oil drains back into the compressor through areplaceable 0.5-3.0 micron oil filter, and oil supplysolenoid, is at high pressure. This high pressure "oilinjection" forces the oil into the compressor where it isgravity fed to the gears and bearings for lubrication.

After Lubricating the gears and bearings, it is injectedthrough orifices on a closed thread near the suction endof the rotors. The oil is automatically injected because ofthe pressure difference between the dischargepressure and the reduced pressure at the suction end ofthe rotors. This lubricates the rotors as well as providesan oil seal against leakage around the rotors to assurerefrigerant compression (volumetric efficiency).

The oil also provides cooling by transferring much of theheat of compression from the gas to the oil keepingdischarge temperatures down and reducing the chancefor oil breakdown.

Oil injected into the rotor cage flows into the rotors at apoint about 1.2 x suction. This assures that a requiredminimum differential of at least 1.8 bar (30 PSID) existsbetween discharge and 1.2 x suction, to force oil intorotor case, a minimum of 0.6 bar (10 PSID) is all that isrequired to assure protection of the compressor. Oilpressure is measured as the difference betweendischarge pressure and the pressure of the oil enteringthe rotor case.

Maximum working pressure of the oil separator is 31 bar(450 PSIG). A relief valve is installed in the oil separatorpiping. The oil level should be above the midpoint of the"lower" oil sight glass when the compressor is running.The oil level should never be above the top of the"upper" sight glass.

2.4 Oil Cooler

Oil cooling is provided by a dedicated air-cooled finnedtube type heat exchanger located in the condensersection of the unit. Oil leaving the oil separator passesthrough this oil cooler section where it is cooled beforereturning back to the compressor.

2.5 Refrigerant Circuits

Each refrigerant circuit uses copper refrigerant pipeformed on computer controlled bending machines toreduce the number of brazed joints resulting in a reliableand leak resistant system.

Liquid line components include: a manual shut-off valvewith charging port, a high absorption removable corefilter-drier, a sight glass with moisture indicator, and athermostatic expansion valve.

Suction lines are covered with closed-cell insulation.

2.6 Economisers

Selected models in the range have economisers fitted tothe refr igerant ci rcui ts. This is arefrigerant-to-refrigerant plate type heat exchanger tomaximise unit capacity and efficiency by achievingadditional liquid refrigerant sub-cooling. The unit controlsystem controls the economiser via a dedicatedsolenoid valve.

2.7 Condenser

The condenser coils are manufactured from seamless,internally enhanced, high condensing coefficient,corrosion resistant copper tubes arranged in staggeredrows and mechanically expanded into corrosionresistant aluminium alloy fins with full height fin collars.They have a design working pressure of 31 bar(450 PSIG).

Standard units have condensers fitted with single speedfans. As an option two speed fans can be fitted. All fansare dynamically and statically balanced, direct drive withcorrosion resistant glass fibre reinforced compositeblades moulded into low noise, full aerofoil crosssection, providing vertical air discharge from extendedorifices for efficiency and low sound. Each fan is locatedin a separate compartment to prevent cross flow duringfan cycling. Guards of heavy gauge, PVC coatedgalvanised steel are provided.

The fan motors are high efficiency, direct drive, 8 pole, 3phase, Class- “F”, current overload protected, totallyenclosed (TEAC) type with double sealed, permanentlylubricated, ball bearings.

2.8 Evaporator

The evaporator is a shell and tube design withrefrigerant on the tube side and water on the shell side.Tubes are formed in a 'U' shape and held in a tubebundle, which is free to expand independent of the shell.An independent refrigerant circuit is provided for eachcompressor. The water side (shell) design workingpressure is 10.3 bar (150 psi) and refrigerant side(tubes) is 24.5 bar (355 psi).

Evaporators have water pass baffles manufacturedfrom corrosion resistant/non metallic compositematerial, removable heads for access to internallyenhanced, seamless, copper tubes. Water vent anddrain connections are also be included.

The water nozzles are fitted with PN16 flanges per ISO7005 part 1a. Companion weld flanges to matchevaporator flanges are supplied loose for fieldinstallation by contractor. All necessary nuts, bolts andgaskets are included.

Evaporators are equipped with a thermostaticallycontrolled heater for protection to -29°C ambient andare insulated with 19 mm flexible closed-cell foam.

2.9 Power and Control Panels

All controls and motor starting equipment are factorywired and function tested. The panel enclosures aredesigned to IP55 and are manufactured from powderpainted galvanised steel. Component mounting panelsare of non-painted galvanised steel to ensure optimumprotective circuit (earthing).

The panel is divided into power sections for eachelectrical system, a control section and a common inputsection. All sections have separate hinged, latched, andgasket sealed doors equipped with wind struts.

2.10 Microprocessor Controls

Fuzzy Logic control is incorporated in the YAES range ofchillers. Fuzzy logic allows the control system to monitorseveral key variables to provide tighter, more stable,chilled liquid temperature control. The control systemmonitors the leaving chilled liquid temperature to trackwhere it has been, where it is now, how fast it is moving,and accurately adjusts chiller operation in anticipation ofexpected performance to minimise hunting and saveenergy.

The microprocessor has the following functions anddisplays:

A liquid crystal 40 character display with text providedon two lines and light emitting diode backlighting foroutdoor viewing.

A colour coded, 35 button, sealed keypad with sectionsfor Display, Entry, Setpoints, Clock, Print, Program andthe unit Auto/Off switch.

The standard controls include: glycol chilling or thermalstorage, automatic pump down, run signal contacts,demand load limit from external building automationsystem input, remote reset liquid temperature resetinput, unit alarm contacts, chilled liquid pump control,automatic or manual reset after power failure, automaticsystem optimisation to match operating conditions.

The software is stored in non-volatile memory (EPROM)to eliminate unit failure due to AC power failure. TheProgrammed Setpoint is stored in a lithium batterybacked memory.

2.11 Motor Current Protection

The microprocessor motor protection provides highcurrent protection to assure that the motor is notdamaged due to voltage, excess refrigerant, or otherproblems that could cause excessive motor current.

If the motor current exceeds the 115% FLA trip pointafter 3 seconds of operation, the microprocessor willshut the system down and lock it out after one fault. Amanual reset of the respective system switch is requiredto clear the fault and restart the system. A thoroughcheck of the motor, wiring, and refrigerant systemshould be carried out before restarting a system that hasfaulted on high motor current.

The microprocessor also provides low motor currentprotection when it senses a motor current less than20% FLA. Low motor current protection is activated 4seconds after start. The microprocessor will shut thesystem down whenever low motor current is sensed andwill lock out a system if three faults occur in 90 minutes.Once a system is locked out on Low Motor Current, itmust be manually reset with the system switch.

The microprocessor also senses low motor currentwhenever a High Pressure Cut-out (HPCO) or MotorProtector (MP) or Phase Rotation Relay (KPR) contactopens. The MP, HPCO and KPR contacts areconnected in series with the motor contactor. Wheneverany of these devices are open, the contactorde-energises and the motor shuts down. Since themicroprocessor is sending a run signal to the contactor,it senses the low motor current below 20% FLA andshuts the system down.

Motor Protector Module

The motor protector module provides thermal overloadprotection.

Three PTC (posit ive temperature coeff icient)thermistors in the motor windings of each phase providethermal protection. The sensor resistance staysrelatively constant at 1 kΩ until a temperature of 130°C(266°F) is sensed. The sensor experiences a rapid risein resistance beyond this temperature. Whenever theresistance of one of the sensors reaches 13 kΩ, themodule trips. Reset is manual after the motor cools andthe sensor resistance drops to 3.25 kΩ.

Phase Rotation relay (KPR)

Each power section is fitted with a phase rotating relayto monitors the 3 phase voltage. Provided the phaserotation is correct the relay will close its contact in thecompressor contactor circuit.

2.15 Functional Description

Cooling (Figure 2.1)

Low pressure liquid refrigerant enters the evaporatorand is evaporated and superheated by the heat energyabsorbed from the chilled water passing through theevaporator shell. Low pressure vapour enters thecompressor where pressure and superheat areincreased. High pressure vapour is passed through theoil separator where compressor oil is removed andrecirculated to the compressor via the oil cooler. Thehigh pressure oil-free vapour is fed to the air cooledcondenser coil and fans where the heat is removed. Thefully condensed liquid enters the economiser.

A small percentage of the of the liquid passes throughan expansion valve, into the other side of theeconomiser where it is evaporated. This low pressureliquid subcools the major part of the refrigerant. Mediumpressure vapour then returns to the compressor. Thesubcooled refrigerant then passes through theexpansion valve where pressure is reduced and furthercooling takes place before returning to the evaporator.

If the warm water flow switch detects water flow the heatrecovery pressure regulating valves are energised. Thevalves allow high-pressure superheated refrigerant,from the oil separators, to enter the twin circuit heatrecovery plate heat exchanger. The refrigerant ispartially condensed as the warm water absorbs heatenergy.

The valves are de-energised when the leaving warmwater temperature sensor registers the high point of theset point dead band. If water flow is maintained thevalves are re-energised if the temperature sensorregisters the low point of the set point dead band.

3 TRANSPORTATION, HANDLING ANDSTORAGE

3.1 Delivery and Storage

To ensure consistent quality and maximum reliability, allunits are tested and inspected before leaving thefactory. Units are shipped completely assembled andcontaining refrigerant under pressure. Units areshipped without export crating unless this has beenspecified on the Sales Order.

If the unit is to be put into storage, before installation, thefollowing precautions should be observed:

Ensure that all openings, such as water connections,are securely capped.

The condensers should be covered to protect the finsfrom potential damage and corrosion, particularly wherebuilding work is in progress.

The unit should be stored in a location where there isminimal activity to limit the risk of accidental physicaldamage.

To prevent inadvertent operation of the pressure reliefdevices the unit must not be steam cleaned.

It is recommended that the unit is periodically inspectedduring storage.

3.2 Inspection

Remove any transit packing and inspect the unit toensure that all components have been delivered andthat no damage has occurred during transit. If anydamage is evident, it should be noted on the shipmentdocumentation and a claim entered according to theinstructions given.

Major damage must be reported immediately to yourlocal YORK representative.

3.3 Moving the Unit

Before moving the unit, ensure that the installation site issuitable for installing the unit and is capable ofsupporting the weight of the unit and all associatedservices.

To avoid injury and damage to the unit. Theunit must only lifted in accordance with therigging instructions label, which is attached tothe unit.

The unit should be lifted using lifting shackles and aspreader bar or frame of sufficient width to preventdamage to the unit from the lifting chains.

The unit must only be lifted by the base frameat the points provided. Never move the unit onrollers, or lift the unit using a fork-lift truck.

Care should be taken to avoid damaging thecondenser coil fins when moving the unit.

(02/05)

035L02519-100 Rev. 1 3-1

Units are provided with four lifting holes in the baseframe which accept the accessory lifting lug set (partnumber 026L00261-000).

The four lugs (2 x RH and 2 x LH) should be inserted intothe respective holes in the base frame and turned sothat the spring loaded pin engages into the hole and theflanges on the lug lock behind the hole. The lugs shouldbe attached to the cables/chains using shackles orsafety hooks.

4 INSTALLATION

4.1 Location Requirements

To achieve optimum performance and trouble-freeservice, it is essential that the proposed installation sitemeets with the location and space requirements for themodel being installed. For dimensions, weight andspace requirements, including service access details,refer to Section 9.

It is important to ensure that the minimum serviceaccess space is maintained for cleaning andmaintenance purposes.

The unit should not be installed directly onflammable materials such as woodenstructures or roofs..

Outdoor Installations

The units can be installed at ground level, or on asuitable rooftop location. In both cases an adequatesupply of air is required. Avoid locations where the airdischarge from the unit may be objectionable.

The location should be selected for minimum sunexposure and away from boiler flues and other sourcesof airborne chemicals that could attack the condensercoils and steel parts of the unit.

If located in an area which is accessible to unauthorisedpersons, steps must be taken to prevent access to theunit by means of a protective fence. This will help toprevent the possibility of vandalism, accidental damage,or possible harm caused by unauthorised removal ofprotective guards or opening panels to expose rotatingor high voltage components.

For ground level locations, the unit must be installed ona suitable flat and level concrete base that extends tofully support the two side channels of the unit baseframe. A one-piece concrete slab, with footingsextending below the frost line is recommended. Toavoid noise and vibration transmission the unit shouldnot be secured to the building foundation.

On rooftop locations, choose a place with adequatestructural strength to safely support the entire operatingweight of the unit and service personnel. The unit can bemounted on a concrete slab, similar to ground floorlocations, or on steel channels of suitable strength. Thechannels should be spaced at the same centres as thevibration mounting holes in the unit base frame andmust be at least 120 mm wide at the contact points. Thiswill allow vibration isolators to be fitted if required.

Any ductwork or attenuators fitted to the unit must nothave a total static pressure resistance, at full unit airflow,exceeding the capability of the fans installed in the unit.

Indoor Installations

The unit can be installed in an enclosed plant roomproviding the floor is level and of suitable strength tosupport the full operating weight of the unit. It is essentialthat there is adequate clearance for airflow to the unit.The discharge air from the top of the unit must be ductedaway to prevent recirculation of air within the plant room.If common ducts are used for fans, non-return dampersmust be fitted to the outlet from each fan.

The discharge ducting must be properly sized with atotal static pressure loss, together with any intake staticpressure loss, less than the available static pressurecapability for the type of fan fitted. The discharge air ductusually rejects outside the building through a louvre.The outlet must be positioned to prevent the air beingdrawn directly back into the air intake for the condensercoils as such recirculation will affect unit performance.

4.2 Location Clearances

Adequate clearances around the unit(s) are required forthe unrestricted airflow for the air-cooled condensercoils and to prevent recirculation of warm discharge airback onto the coils. If clearances given are notmaintained, airflow restriction or recirculation will causea loss of unit performance, an increase in powerconsumption and may cause the unit to malfunction.Consideration should also be given to the possibility ofdown draughts, caused by adjacent buildings, whichmay cause recirculation or uneven unit airflow.

For locations where significant cross winds areexpected, such as exposed roof tops, an enclosure ofsolid or louvre type is recommended to prevent windturbulence interfering with the unit airflow.

When units are installed in an enclosure, the enclosureheight should not exceed the height of the unit on morethan one side. If the enclosure is of louveredconstruction the same requirement of static pressureloss applies as for ducts and attenuators stated above.

(02/05)

035L02519-100 Rev. 1 4-1

Where accumulation of snow is likely, additional heightmust be provided under the unit to ensure normal airflowto the unit.

The clearance dimensions given arenecessary to maintain good airflow andensure correct unit operation. It is alsonecessary to consider access requirementsfor safe operation and maintenance of the unitand power and control panels. Local healthand safety regulat ions, or pract icalconsiderations for service replacement oflarge components, may require largerclearances than those given in Section 9.

4.3 Installation of Vibration Isolators

Optional sets of vibration isolators can be supplied loosewith each unit.

Using the Isolator tables (refer to Section 9),identify each mount and its correct location on theunit.

Mounts - Installation

Place each mount in its correct position and lowerthe unit carefully onto the mounts.

Transfer the unit weight evenly to the springs byturning the mount adjusting nuts. This should bedone until the unit base is level.

4.4 Pipework Connection

General Requirements

The following piping recommendations are intended toensure satisfactory operation of the unit(s). Failure tofollow these recommendations could cause damage tothe unit, or loss of performance, and may invalidate thewarranty.

The maximum flow rate and pressure drop forthe evaporator must not be exceeded at anytime. Refer to Section 9 for details.

The liquid must enter the evaporator by the inletconnection (refer to Section 9 ).

A flow switch must be installed in the customerpipework at the outlet of the evaporator and wiredback to the control panel using screened cable. Fordetails refer to “Electrical Connection.” This is toprevent damage to the evaporator caused by theunit operating without adequate liquid flow. Toprevent turbulent flow there must be straightpipework either side of the flow switch equal inlength to at least 5 times the diameter of the pipe.

The flow switch used must have gold platedcontacts for low voltage/current operation. Paddletype flow switches suitable for 10 barg workingpressure and having a 1" N.P.T. connection can beobtained from YORK as an accessory for the unit.Alternatively a differential pressure switch sitedacross an orifice plate may be used, preferably ofthe high/low limit type.

The chilled liquid pump installed in the pipeworksystem should discharge directly into the unitevaporator section of the system. The pump maybe controlled external to the unit — but an overridemust be wired to the control panel so that the unitcan start the pump in the event that the liquidtemperature falls below the minimum setting. Fordetails refer to “Electrical Connection.”

Pipework and fitt ings must be separatelysupported to prevent any loading on theevaporator. Flexible connect ions arerecommended which wi l l a lso minimisetransmission of vibrations to the building. Flexibleconnections must be used if the unit is mounted onanti-vibration mounts as some movement of theunit can be expected in normal operation.

Pipework and fittings immediately next to theevaporator should be readily de-mountable toenable cleaning before operation, and to facilitatevisual inspection of the exchanger nozzles.

The evaporator must be protected by a strainer,preferably of 30 mesh, fitted as close as possible tothe liquid inlet connection, and provided with ameans of local isolation.

The evaporator must not be exposed to flushingvelocities or debris released during flushing. It isrecommended that a suitably sized by-pass andvalve arrangement is installed to allow flushing ofthe pipework system. The by-pass can be usedduring maintenance to isolate the heat exchangerwithout disrupting flow to other units.

(02/05)

4-2 035L02519-100 Rev. 1

Thermometer and pressure gauge connectionsshould be provided on the inlet and outletconnections of the evaporator.

Drain and air vent connections should be providedat all low and high points in the pipework to permitdrainage of the system and to vent any air in thepipes.

Liquid systems at risk of freezing, due to lowambient temperatures, should be protected usinginsulation and heater tape and/or a suitable glycolsolution. The liquid pump must also be used toensure liquid is circulated when the ambienttemperature approaches freezing point. Insulationshould also be installed around the evaporatornozzles. Heater tape of 21 watts per metre underthe insulat ion is recommended, suppliedindependently and controlled by an ambienttemperature thermostat set to switch on at 3°Cabove the freezing temperature of the liquid.

The liquid circulation pump must be controlled bythe unit. This will ensure that when the liquidtemperature falls within 2 or 3°C of freezing thepump will start.

The evaporator is protected by heater mats underthe insulation which are supplied from the unitcontrol system power supply. During risk offreezing the control system should be left switchedon to provide the freeze protection function unlessthe liquid systems have been drained.

Any debris left in the water pipework betweenthe strainer and evaporator could causeserious damage to the tubes in the evaporatorand must be avoided. The installer/user mustalso ensure that the quality of the water incirculation is adequate, without any dissolvedgasses which can cause oxidation of steelparts within the evaporator.

4.5 Water Treatment

The unit performance given in the Design Guide isbased on a fouling factor of 0.044 m² °C/kW (0.00025ft²hr°F/Btu). Dirt, scale, grease and certain types ofwater treatment will adversely affect the heat exchangersurfaces and therefore unit performance. Foreignmatter in the water system can increase the heatexchanger pressure drop, reducing the flow rate andcausing potential damage to the heat exchanger tubes.

Aerated, brackish or salt water is not recommended foruse in the water system. YORK recommend that a watertreatment specialist is consulted to determine that theproposed water composition will not affect theevaporator materials of carbon steel and copper. ThepH value of the water flowing through the evaporatormust be kept between 7 and 8.5.

4.6 Heat Recovery Plate Exchangers

The plate heat exchangers fitted to YAES units havemultiple water passes with narrow water channels thatcan be subject to premature fouling if the design of thewater system is not given adequate consideration.

Water systems should be of the closed loop type, withno tanks open to the atmosphere. The system shouldhave serviceable mesh strainers giving a filtration levelto at least 150 microns and anti-corrosion protectionusing appropr iate corrosion inhibi tors, wi thconsideration to using purified water in geographicareas where mains water has a high soluble solidcontent.

YORK recommend that a water treatment specialist isconsulted to determine that the proposed watercomposition will not affect the plate heat exchangers’materials. Constant loss systems are not recommendedin any circumstances.

4.7 Pipework Arrangement

The following are suggested pipework arrangements forsingle and multiple unit installations, each unit should bepiped as shown.

4.8 Connection Types & Sizes

Standard chilled liquid connections on all evaporatorsare PN 16 flanges per ISO 7005 part 1a. For sizesrelevant to individual models refer to Section 9.

Recommendations of the Building ServicesResearch Association

4.9 Refrigerant Relief Valve Piping

evaporators and oil separators are each protectedagainst internal refrigerant over-pressure and fire byrefrigerant relief valves. The pressure relief valve is setat the design pressure of the system and has dischargecapacity required by the relevant standard. Forevaporators, a pressure relief valve is mounted on eachof the main refrigerant lines connecting the evaporatorto the compressors. On oil separators the pressurerelief valve is mounted on the side near the top of thevessel body.

It is recommended that a piece of pipe is fitted to eachvalve and directed so that when the valve is activatedthe release of high pressure gas and liquid cannot be adanger or cause injury. For indoor installations pressurerelief valves should be piped to the exterior of thebuilding.

The size of any pipework attached to a relief valve mustbe of sufficient diameter so as not to cause resistance tothe operation of the valve. Unless otherwise specified bylocal regulations, the internal diameter depends on thelength of pipe required and is given by the formula:

D5 = 1.447 x LD = minimum pipe internal diameter in centimetresL = length of pipe in metres

If relief pipework is common to more than one valve itscross sectional area must be at least the total requiredby each valve. Valve types should not be mixed on acommon pipe. Precautions should be taken to ensurethat the exit of relief valves/vent pipe remain clear ofobstructions at all times.

4.10 Ductwork Connection

General Requirements

The following ductwork recommendations are intendedto ensure satisfactory operation of the unit. Failure tofollow these recommendations could cause damage tothe unit, or loss of performance, and may invalidate thewarranty.

When ducting is to be fitted to the fan discharge it isrecommended that the duct should be the samecross sectional area as the fan outlet and straightfor at least one metre to obtain static regain fromthe fan.

Ductwork should be suspended with flexiblehangers to prevent noise and vibration beingtransmitted to the structure. A flexible joint is alsorecommended between the duct attached to thefan and the next section for the same reason.

The unit is not designed to take structural loading.No significant amount of weight should be allowedto rest on the fan outlet flange, deck assemblies orcondenser coil module. No more than one metre oflight construction ductwork should be supported bythe unit. Where cross winds may occur, anyductwork must be supported to prevent sideloading on the unit.

If the ducts from two or more fans are to becombined into a common duct, back-flow dampersshould be fitted in the individual fan ducts. This willprevent recirculation of air when only one of thefans is running.

Units are supplied with outlet guards for safety andto prevent damage to the fan blades. If theseguards are removed to fit ductwork, adequatealternative precautions must be taken to ensurepersons cannot be harmed or put at risk fromrotating fan blades.

4.11 Electrical Connection

The following connection recommendations areintended to ensure safe and satisfactory operation of theunit. Failure to follow these recommendations couldcause harm to persons, or damage to the unit, and mayinvalidate the warranty.

No additional controls (relays, etc.) shouldbe mounted in the control panel. Powerand control wiring not connected to thecontrol panel should not be run throughthe control panel. If these precautions arenot followed it could lead to a risk ofelectrocution. In addition, electrical noisecould cause malfunctions or damage theunit and its controls.

After connection do not switch on mainspower to the unit . Some internalcomponents are live when mains isswitched on and this must only be done byAuthorised persons.

The unit ON/OFF switch on the front of the control panelhas been set in the “OFF” position at the factory.

This switch MUST remain in the “OFF” position until theunit is commissioned by YORK Authorised personnel. Ifthe switch is set to the “ON” position beforecommissioning then it must be reported to YORK,otherwise the warranty may be invalidated.

4.12 Power Wiring

The units are suitable for 380 or 400 V,3 phase, 50 Hz nominal supplies only.Minimum allowable 342 V.Maximum allowable 440 V.

All electrical wiring should be carried out in accordancewith local regulations. Route properly sized cables tocable entries on the bottom of the power and controlpanel.

In accordance with EN 60204 it is the responsibility ofthe user to install over-current protection devicesbetween the supply conductors and the power supplyterminals on the unit.

To ensure that no eddy currents are set up in the powerpanel, the cables forming each 3 phase power supplymust enter via the same cable entry.

All sources of supply to the unit must betaken via a common points of isolation (notsupplied by YORK).

Control Circuit Transformer (Primary VoltageTappings)

The control circuit transformer (400 V, 2 Ø, 50 Hz)providing the 230 V, 1 Ø, 50 Hz power supply to the unitcontrol system is fitted in a separate IP55 enclosuremounted on the unit framework. It is important to checkthat the correct primary tapping has been used:

With the supply to the unit isolated remove the lid tothe transformer enclosure.

Check that the tapping used conforms to the sitesupply voltage. The two tappings are 342-424 Vand 360-440 V.

Remote Emergency Stop Device

If required, a remote emergency stop device can bewired into the unit. This device should be rated at10 amps, 230 V, AC-15. The device should be wired intoterminals 3 and 4 in the common input section. Theexisting link must first be removed. Terminals 3 and 4are in a circuit protected by a 10 amp class gG fuse.When operated it removes the 230 Vac control supply tothe electronics. All devices are de-energised includingcompressor and fan contactors. The loss of supply tothe power supply board results in the display going off.

To conform with the requirement of EN 418and EN 60204-1 that re-set t ing theemergency stop device will not initiate arestart , ‘POWER FAIL RESTART’ should beprogrammed under the ‘PROGRAM’ key to‘MANUAL’. ‘MANUAL’ restart requires a resetusing the unit ON/OFF switch on the controlsection door.

4.13 Output Signals

All wiring to the voltage free contact terminal block onthe relay board requires a supply provided by thecustomer maximum voltage 254 Vac, 28 Vdc.

The customer must take particular care deriving thesupplies for the voltage free terminals with regard to acommon point of isolation. Thus, these circuits whenused must be fed via the common point of isolation sothe voltage to these circuits is removed when thecommon point of isolation to the unit is opened. Thiscommon point of isolation is not supplied by YORK.

In accordance with EN 60204 it is recommended thatthe customer wiring to these terminals uses orangewires. This will ensure that circuits not switched off bythe units supply disconnecting device are distinguishedby colour, so that they can easily be identified as liveeven when the unit disconnecting devices are off. TheYORK voltage free contacts are rated at 125 VA.

All inductive devices (relays) switched by the YORKvoltage free contacts must have their coil suppressedusing standard RC suppressors. If these precautionsare not followed, electrical noise could causemalfunctions or damage to the unit and its controls.

Chilled Liquid Pump Starter

Terminals 33 and 34 close to start chilled liquid pump.This contact can be used as a master start/stop for thepump in conjunction with the daily start/stop schedule. Ifno schedule is set, the contact will close when the unitswitch is set to on. The contact must be used so that thecontact can start the pump in the event of a lowtemperate liquid condition. A stop/start timer is includedso that the pump will not be asked to restart within 30seconds of stopping.

Run Contact

Terminals 35 and 36 close to indicate that a system isrunning.

Alarm Contacts

Each refrigerant system has a voltage-free change overcontact which will operate to signal an alarm conditionwhenever a system locks out, or there is a power failure.To obtain system alarm signal, connect the alarm circuitto volt free terminals 30 and 32 (open on alarm) or 31and 32 (close on alarm) for No. 1 system and volt freeterminals 37 and 39 (open on alarm) or 38 and 39 (closeon alarm) for No. 2 system.

4.14 System Inputs

All wiring to the relay board input signal terminal block(nominal 30 Vdc) must be run in screened cable, withthe screen earthed at the panel end only. Run screenedcable separately from mains cable to avoid electricalnoise pick-up. The cables should be routed via the glandplate in the bottom of the common input section.

The voltage free contacts must be suitable for 30 Vdc(gold contacts recommended). If the voltage freecontacts form part of a relay or contactor, the coil of thedevice must be suppressed using a standard RCsuppressor. The above precautions must be taken toavoid electrical noise which could cause a malfunctionor damage to the unit and its controls.

Flow Switch

A chilled liquid flow switch of suitable type must beconnected to terminals 13 and 18 to provide adequateprotection against loss of liquid flow.

Remote Start/Stop

Remote start/stop can be accomplished using a timeclock, manual contact or other ‘voltage free’ contact,terminals 15 and 18 with terminals 12 and 15 linked inthe control section of the control panel. The contactmust be closed to allow the unit to run. Any time thecontact opens, the unit will shutdown and the ‘NO RUNPERM’ message will be displayed.

For individual system start/stop contacts connect No. 1system to terminals 15 and 18 and No. 2 system toterminals 12 and 15. With the associated contact openthe ‘NO RUN PERM’ message will be displayed and theassociated systems will not run.

Remote Print

Closure of suitable contacts connected to terminals 13and 18 will cause a hard copy printout of OperatingData/Fault History to be made if an optional printer isconnected to the RS 232 port.

Remote Set Point Offset - Temperature

Timed closure of suitable contacts connected toterminals 13 and 17 (PWM contacts) will give remoteoffset function of the chilled liquid set point if required.

Remote Set Point Offset - Current

Timed contact closure of a suitable contact connected toterminals 13 and 16 (PWM contact) will give remoteoffset of EMS% CURRENT LOAD LIMIT.

5 COMMISSIONING

5.1 Preparation

Commissioning of this unit should only becarried out by YORK Authorised personnel.

The Microprocessor Based Control System (MBCS)Operating Instructions must be read in conjunctionwith this section.

The unit On/Off switch on the front of the control panelhas been set to the Off position at the factory. Thisswitch must remain in the Off position, preventingrunning of the unit until commissioned by Authorisedpersonnel. If the switch has been set to the On positionbefore commissioning then it must be reported to YORKInternational otherwise the warranty may be invalidated.

Preparation - Power Off

The following checks should be made with the customersupply/supplies to the unit switched off.

Inspection: Inspect unit for installation damage. Iffound take action and/or repair as appropriate.

Refrigerant charge: Units are normally shipped asstandard with a full refrigerant operating charge. Checkthat refrigerant pressure is present in both systems andthat no leaks are apparent. If no pressure is present aleak test must be undertaken, the leak(s) located andrepaired. Repaired systems and units supplied with anitrogen holding charge must be evacuated with asuitable vacuum pump/recovery unit as appropriate tobelow 100 microns.

Charging from the liquid connection isnecessary on R407C to ensure the correctrefrigerant mix is maintained.

Do not liquid charge with static water in the evaporator.Care must also be taken to liquid charge slowly to avoidexcessive thermal stress at the charging point. Once thevacuum is broken, charge into the condenser coils withthe full operating charge as given in Section 9.

Valves: Open the compressor suction and dischargevalves fully (counter-clockwise) then close one turn ofthe stem to ensure operating pressure is fed to thepressure transducers. Open the compressor motorcooling valves and the liquid line service valves fully andensure the oil return line ball valves are open.

Compressor oil: The compressor oil level must bebetween the two sight glasses on the oil separators.

Fans: Check that all fans are free to rotate and are notdamaged. Ensure blades are at the same height whenrotated. Ensure fan guard is securely fixed.

Isolation/protection: Verify that all sources of electricalsupply to the unit are taken from point(s) of isolation.

Control panel: Check the panel to see that it is free offoreign materials (wire, metal chips, etc.) and clean out ifrequired.

Power connections: Check the customer powercables are connected correct ly. Ensure thatconnections of power cables within the panels to theconnection points are tight.

Earthing: Verify that the units protective terminal(s) areproperly connected to a suitable earthing point. Ensurethat all unit internal earth connections are tight.

Switch Settings: Ensure that the unit On/Off switch onthe control panel and the microprocessor board systemswitches S2 and S5 are set to “0" (OFF). Set the redhandled emergency stop device on the options panel to”1" (ON). For units fitted with door interlocked isolationdevices the panel doors must be closed and the devicesset to “1" (ON). The customers disconnection devicescan now be set to ON.

The machine is now live!

Compressor heaters: Verify the compressor heatersare energised.

Water System: Verify that the chilled liquid system hasbeen installed correctly, and has been commissionedwith the correct direction of water flow through theevaporator. Inlet should be at the refrigerant pipeworkconnection end of the evaporator. Purge air from the topof the evaporator using the plugged air vent mounted onthe top of the evaporator body. Flow rates and pressuredrops must be within the limits given in Section 9.Operation outside of these limits is undesirable andcould cause damage.

Flow switch: Verify a chilled water flow switch iscorrectly fitted in the customer’s pipework on theevaporator outlet, and wired into the control panelcorrectly.

Temperature sensor(s): Ensure the leaving liquidtemperature sensor is coated with heat conductivecompound (part no. 013-00890-000) and is inserted inthe water outlet sensor pocket of the evaporator. Thissensor also acts as the freeze protection thermostatsensor and must always be in the water OUTLET sensorpocket.

5.2 First Time Start-up

During the commissioning period there shouldbe sufficient heat load to run the unit understable full load operation to enable the unitcontrols, and system operation to be set upcorrectly and a commissioning log taken.Read the following section in conjunction withthe MBCS Manual, then proceed step by stepas follows:

Interlocks: Verify that liquid is flowing through theevaporator and that heat load is present. Ensure thatany remote run interlocks are in the run position and thatthe run schedule requires the unit to run or is overridden.

System switches: Set the system switches on themicroprocessor board to the ‘ON’ position — seeoperating sequence in the MBCS Manual.

Start-up: Press the ‘STATUS’ key, and set the unitswitch to the ON position to start the unit (there may be afew seconds delay before the first compressor startsbecause of the anti-recycle timer). Be ready when eachcompressor starts, to switch the unit off immediately ifany unusual noises or other adverse conditionsdevelop. Use the appropriate emergency stop device ifnecessary. Also refer to the MBCS Manual for thenormal operating sequence from start-up.

Oil pressure: When a compressor starts, press therelevant ‘SYSTEM DATA’ key and verify that oildifferential pressure develops immediately. If oilpressure does not develop, the automatic controls willshut down the compressor (see the MBCS Manual forthe flow chart of the automatic oil pressure safetysystem). Under no circumstances should a restartattempt be made on a compressor which does notdevelop oil pressure immediately. Switch the unit switchto the Off position.

Refrigerant flow: When a compressor starts a flow ofliquid refrigerant will be seen in the liquid line sight glass.After several minutes operation and providing a fullcharge of refrigerant is in the system, the bubbles willdisappear and be replaced by a solid column of liquid.

Fan rotation: As discharge pressure rises, thecondenser fans operate in stages to control thepressure. Verify that the fan operation is correct for thetype of unit.

Suction Superheat: Check suction superheat atsteady full compressor load only. It is important that nobubbles show in the liquid line sight glass. Measuresuction temperature on the copper line about 150 mmbefore the compressor suction service valve. Measuresuction pressure at the compressor service valve.Superheat should be 4°C to 5°C relative to the ‘dew’temperature.

Expansion valve adjustment: The expansion valvesare factory set and should not need adjustment. If anysuperheat values are out of range, however, theexpansion valve adjusting screw should be adjusted nomore than 1 turn at a time (‘in’ to increase superheat,‘out’ to decrease superheat), allowing at least 10minutes for the valve to stabilise before rechecking thevalue of superheat.

Subcooling: Check liquid subcooling at steady fullcompressor load only. It is important that all fans arerunning for the system. Measure liquid line temperatureon the copper line beside the main liquid line servicevalve. Measure liquid pressure at the liquid line servicevalve. Subcooling should be 5°C to 7°C relative to the’bubble’ temperature. If subcooling is out of range add orremove refrigerant as required. Do not overcharge theunit.

General operation: After completion of the abovechecks for System 1 repeat the process for eachsubsequent system. When all run correctly, stop theunit, switch all applicable switches to the ‘ON’ positionand restart the unit. Check that loading occurs asspecified in the MBCS and that general operation iscorrect.

6 UNIT OPERATION

6.1 General Description

The units are designed to work independently, or inconjunction with other equipment via a YORK ISNbuilding management system or other automatedcontrol system. When operating, the unit controlsmonitor the chilled liquid system temperature at the unitand take the appropriate action to maintain thistemperature within desired limits. This action will involverunning one or more compressors at a suitable load stepto match the cooling effect of the refrigerating systemsto the heat load on the liquid system. The heat removedfrom the chilled liquid is then rejected from the air cooledcondenser coils.

The following sections give an overview of the operationof the unit. For detailed information, reference should bemade to the MBCS Operating Instructions for the unit.

6.2 Start-up

Check the main power supplies to the unit are ‘ON’, allrefrigerant service valves are open (anti-clockwise oneturn short of fully open) and chilled liquid flow has beenestablished (unless the unit chilled liquid pump startcontrol is being used, in which case just ensure thepump supply is on). Ensure only the correct systemswitches (SYS 1 or 2) on the microprocessor circuitboard are in the ‘ON’ position.

Press the ‘STATUS’ key on the keypad and then switchthe unit 'ON/OFF' switch on the control section door tothe 'ON' position.

The controller will perform a pre-check to ensure that thedaily/holiday schedule and any remote interlocks willallow the unit to run, all safety cut-outs are satisfied andthat cooling load is required (i.e. that the chilled liquidtemperature is outside the set limits). Any problemsfound by the pre-check will be displayed if present. If noproblems are present and cooling duty is required thelead compressor will start.

The display will show the anti-coincidence timer statusfor the lag compressor, followed by `NO COOL LOAD’until it is called to operate by the control system.

6.3 Normal Running and Cycling

Once the unit has been started, all operations are fullyautomatic. After an initial period at minimum capacity onthe lead compressor, the control system will adjust theunit load depending on the chilled liquid temperatureand rate of temperature change. If high heat load ispresent, the controller will increase the capacity of thelead compressor and/or start-up other compressors.

If very little heat load is present, the lead compressor willcontinue at minimum capacity or may simply stop againto avoid overcooling the liquid. If the latter is the case,one compressor will restart automatically should theliquid temperature rise again.

Once a compressor is running, discharge pressure risesas refrigerant is pumped into the air cooled condensercoils. This pressure is controlled by stages of fans toensure maximum unit efficiency whilst maintainingsufficient pressure for correct operation of thecondensers and expansion valves.

When a compressor is running the controller monitorsoil pressure, motor current, and various other systemparameters such as discharge pressure, chilled liquidtemperature, etc. Should any problems occur, thecontrol system will immediately take appropriate actionand display the nature of the fault (see MBCS Manual).

6.4 Shutdown

The unit can be stopped at any time by switching the unit'ON/OFF' switch on the control section door to the 'OFF'position. The compressor heaters will energise toprevent refrigerant condensing in the compressor rotorsand to prevent the compressor oil becoming saturatedwith refrigerant. If ambient temperatures are low, theevaporator heater mats will also energise to prevent thepossibility of liquid freezing in the vessel.

To prevent damage the to the unit the controlsupply to the compressor heaters andevaporator heater mats should not beswitched off, even when the unit is notrequired to run.

If mains power must be switched off, (for extendedmaintenance or a shutdown period), the compressorsuction, discharge and motor cooling service stopvalves should be closed (clockwise) and if there is apossibility of liquid freezing due to low ambienttemperatures, the evaporators should be drained.Valves should be opened and power must be switchedon for at least 8 Hours (36 Hours if ambient temperatureis over 30°C ) before the unit is restarted.

035L02519-100 Rev. 1 6-1

6.5 Optional Heat Recovery Operation

High temperature/pressure refrigerant gas enters therefrigerant side of the heat recovery (HR) condenserfrom the oil separator (OS). The temperature of thewater through the HR condenser increases as therefrigerant gas condenses.

HR condenser leaving water temperature control isaccomplished by maintaining a suitable constantcondensing pressure within the refrigerant side of theHR condenser. This is achieved by servo-operatedpressure regulating valves No. 1 and No. 2 located inparallel in the refrigerant outlet line from the HRcondenser. Valve No. 1 is smaller and set to operate at0.5 bar below the operating pressure of the main No. 2valve. When the unit starts up, this valve is the first toopen and allows any liquid refrigerant present in the HRcondenser to enter the air cooled condenser.

The main HR condenser pressure-regulating valve(valve number 2) is a larger servo-operated valve fittedwith an electric shut-off override solenoid valve. Whenthis solenoid valve is closed (de-energized) the mainvalve will close provided all of the following conditionsare met:

Hot water flow switch in hot water line is closed.

Run time is greater than 200 seconds.

The leaving hot water temperature is greater than 30 °Cand less than (Hot Water Leaving Set Point minus HotWater Leaving Set Point Differential).

Discharge temperature is less than 95 °C.

The system is not pumping down.

Fan discharge pressure is greater than (217.5 minus (50minus Hot Water Leaving Set Point) multiplied by 1.8)divided by 14.5.

The pilot valve will be open (energized) and the mainvalve open when any of the following conditions exist::

Hot water flow switch is open.

The system is pumping down or off.

Hot water leaving temperature is less than 25 °C orgreater than Hot Water Leaving Set Point.

The system run time is less than/equal to 200 seconds.

Compressor discharge pressure is less than 11 bar.

Discharge temperature is greater than 114 °C with onlyone system running.

6.6 Setting up of Heat Recovery Controls

The factory setting of the pressure regulating valves isapproximately 21.5 bar g for the No. 1 pressureregulating valve and 22.0 bar g for the No. 2 pressureregulating valve. This is for a leaving hot watertemperature of 50 °C. Turning the pressure regulatingspindle ( looking at the top ) clockwise increases thepressure setting and anti clockwise decreases thepressure.

From a position of fully anti clockwise to17 bar g is 11 turns and to 22 bar g is 13 turns.

Connect pressure gauges (suitable for 28 bar) on theflexible lines of the compressor discharge on bothsystems. Ensure that the gauges can be seen whenadjusting the regulators on pressure regulating valvesinside the condenser module.

Set the required leaving hot water temperature between35 and 50 °C using the program key on the control panel(refer to MBCS Manual for details). The 'HOT WATERSETPOINT' should be set to the required value and the'HOT WATER SETPOINT DIFFERENTIAL' should beset to between 2 and 3 °C.

The setting of the 'HOT WATER SETPOINT' adjusts thepressure at which the fan staging intervals (ON andOFF) change, and the pressure at which the solenoidvalve on the No 2 pressure regulating valve energisesand de-energises in accordance with the graph below .

This is the pressure within the air cooledcondenser. The pressure 'FAN DP' can bedisplayed on the control panel display usingthe System Data key

The setting of the regulators on the two pressureregulation valves can be undertaken when the pressurein the air cooled condenser has de-energised thesolenoid on No. 2 pressure regulating valve. At this timethe regulators on two pressure regulation valves will becontrolling the discharge pressure from the compressorthrough the heat recovery condenser to the valves.

Use the graph to determine the pressure setting of thepressure regulator on the No. 1 pressure regulatingvalve according to the required hot water leavingtemperature. At 43 °C the pressure setting is 19 bar,which is the compressor discharge pressure as read onthe gauge connected to the compressor. Turn thepressure regulator spindle on the No 1 pressureregulating valve anti clockwise until the pressure on thedischarge gauge for that system reads 19.0 bar. Thenturn the regulator spindle on the No 2 pressureregulating valve anti clockwise until the pressure on thedischarge gauge is slightly below 19.0 bar - at thissetting the discharge pressure will fluctuate. Then turnthe spindle 1/3 turn clockwise. This will set the openingof the No. 2 pressure regulating valve 0.5 bar higherthan on the No. 1 pressure regulating valve - and thedischarge pressure will be steady. The setting of thepressure regulators is best undertaken when bothsystems are operating at 100% capacity.

Unit status: Press the ‘STATUS’ key on the keypad andensure no fault messages are displayed (refer to theMBCS Manual for explanation of messages and theTrouble Shooting section for courses of action).

Refrigerant leaks: Visually check the heat exchangers,compressors and pipework for damage and gas leaks.

Airflow obstructions: Check the air cooled condensercoil intakes and adjacent areas are clear of foreignmaterials or obstructions e.g. paper, leaves, etc.

Operating conditions: Read the operating pressuresand temperatures at the control panel using the displaykeys and check that these are within the operatinglimitations given in the MBCS manual.

Compressor oil level: Check the compressor oil levelafter the compressor has been operating on ‘FULLLOAD’ for approximately half an hour. The oil levelshould be between the upper and lower sight glasses onthe oil separators.

Refrigerant charge: When a system starts up, orsometimes after a change of capacity, a flow of bubbleswill be seen in the liquid line sight glass. After a fewminutes of stable operation, the bubbles should clearleaving just liquid refrigerant showing in the sight glass.

7.3 Scheduled Maintenance

The maintenance operations detailed in the followingtable should be carried out on a regular basis by asuitably qualified Service Engineer. It should be notedthat the interval necessary between each ‘minor’ and‘major’ service can vary depending on, for instance,application, site conditions and expected operatingschedule. Normally a ‘minor’ service should be carriedout every three to six months and a ‘major’ service oncea year. It is recommended that your local YORK ServiceCentre is contacted for recommendations for individualsites.

7.4 In Service Inspection

YORK International believe that their vessel designs do not lend themselves to corrosion. A corrosion allowance of1 mm has however been included within the design calculations for the thickness of the vessel shell of which isassessed as being appropriate for the design life of the vessel.

A check on the vessel shell thickness must be conducted by the user every five years by ultrasonic examination orother appropriate methods of examination.

YORK International believe that periodic in service proof testing (ie; hydro tests) is not required. However, YORKInternational recognise that national regulations may require such testing to be conducted.

9.13 Space Requirements

The recommended clearances and dimensions are the distances between the edge of the units and thearchitectural enclosure surrounding them. It is important that adequate space is available to ensure that airdischarged via the fans is not recirculated into the condenser coil intake, which would reduce the unit capacity.

The dimensions at the front and rear of the units allow for access to the control panel and for component removal.

The enclosure height should not exceed the height of the units except that only one adjacent wall may be higher thanthe unit. Horizontal obstructions or overhangs should not be closer than 15 metres above the top of any unit and noobstructions are allowed directly above the unit.
