Moving and Storage Move units in the normal “Up” orientation as indicated by the labels on the unit packaging. Units may be stacked a maximum of two high and should be unstacked before attempting to move units. When the equipment is received, all items should be carefully checked against the bill of lading to ensure that all crates and cartons have been received in good con-dition. Examine units for shipping damage, removing unit packaging if necessary to properly inspect unit. Units in question should also be internally inspected. If any damage is observed, the carrier should make the proper notation on delivery receipt acknowledging the damage.

Water Quality In ground water situations where scaling could be heavy or where biological growth such as iron bacteria will be pres-ent, a closed loop system is recommended. The heat exchanger coils in ground water systems may, over a period of time, loseheatexchangecapabilitiesduetoabuildupofmineraldepositsinside.Thesecanbecleaned,butonlybyaqualifiedservicemechanic,asspecialsolutionsandpumpingequipmentarerequired.Desuperheatercoilscanlikewisebecomescaled and possibly plugged. In areas with extremely hard water, the owner should be informed that the heat exchanger mayrequireoccasionalflushing.

Units with cupronickel heat exchangers are recommended for open loop applications due to the increased resistance to build-up and corrosion, along with reduced wear caused by acid cleaning.

Setting Vertical Units

The entire base of the unit should be supported by a level, vibration-absorbing pad that is slightly larger than the unit cabinet.Itisnotnecessarytoanchortheunittothefloor(seeFigure5).

Duct System Asupplyairductflangeisprovidedforfieldinstallationtofacilitatethesecureductconnectionatthejobsite.Anoptionalfilterrack/returnairductcollarisavailable.Aflexibleconnectoris recommended for discharge and return air duct connections on metal duct systems to prevent vibration transmission. It is recommended that all ductwork be insulated with a minimum of 1/2-inchcoatedinsulation.Installationoftheunitswithuninsu-lated ductwork in an unconditioned space is not recommended, as the system’s performance will be adversely affected.

Condensate Drain On vertical units, the internal condensate drain assembly consists of a drain tube which is connected to the drain pan, a 3/4-inchPVCfemaleadapterandaflexibleconnectinghose.The female adapter may exit either the front or the side of the cabinet.Theadaptershouldbegluedtothefield-installedPVCcondensaterpiping.Onverticalupflowunits,acondensatehose is inside all cabinets as a trapping loop; therefore, an externaltrapisnotnecessary.ThefieldinstalledPVCcon-densate piping and unit connection must be properly glued to prevent water leakage.

Field Conversion ResidentialVersatecverticalunitsarecapableofbeingfield

converted from left return to front or right return by relocating the control box to the side (under the air coil) or to the back (respec-tively). To convert, remove four screws holding the control box in place. Relocate control box to desired location in compressor sec-tion. Replace screws. Ensure that wiring does not come in contact with water or refrigerant lines.

Water connections on residential models are made inside the compressor compartment. Knockouts are provided in the units basetoallowseveralfieldsuppliedpipingconnections.

Electrical Connections Be sure that the available power is the same voltage and phase as that shown on the unit serial plate(s). Line and Lowvoltagewiringmustbedoneinaccordancewithlocalcodesand/ortheNationalElectricCode. Connecting the incoming line voltage wires to the “L” side of the compressor contactor makes the line voltage connection. Consult the unit data plate to determine the proper fuse size.

CAUTION: The printed circuit board incorporates static sensitive CMOS devices. Touching the board or its components may result in damage as a result of static discharge. To prevent damage during service, it is recommened that the tech-nician use a static discharge wrist strap, which is grounded to the heat pump chassis. When handling the circuit board, hold by the edges and avoid contact with electrical componenets. Circuit boards should always be stored in the manufacturer’s static protected bag prior to installations.

System Cleaning and Flushing

Cleaning and Flushing Prior to start up of any heat pump, the water circulating system mustbecleanedandflushedofalldirtanddebris. If the system is equipped with water shutoff valves, the supply and return runouts must be connected together at each unit location (This willpreventtheintroductionofdirtintotheunit,seeFigure11).Thesystemshouldbefilledatthewatermake-upconnectionwithallairventsopen.Afterfilling,ventsshouldbeclosed. The contractor should start the main circulator with the pressure reducingvalvemakeupopen.Ventsshouldbecheckedinsequenceto bleed off any trapped air and to verify circulation through all compo-nents of the system.

Loop static pressure may decrease soon after initial installation, due to pipe expansion and loop temperature change. Running the unit for at least 30 minutes after the system has been completely purged of air will allow for the “break-in” period.

Unit Startup Connecting the incoming line voltage wires to the “L” side of the compressor contactor makes the line voltage connec-tion. Consult the unit data plate to determine the proper fuse size.

208 Volt Operation All208-230voltunitsarefactorywiredfor230-voltoperation.For208-voltoperation,theredandbluetransformerwires must be switched. Before powering the unit, check the following.

NOTE: Use check, test & start form available from your equipment representative.

Verify the following:Highvoltageiscorrectandmatchesnameplate•Fuses,breakersandwiresizearecorrect•Low voltage wiring is complete•Pipingiscompleteandthewatersystemhasbeencleanedandflushed•Airispurgedfromclosedloopsystem•Isolation valves are open and water control valves or loop pumps are wired•Condensate line is open, trapped and correctly pitched•Transformer has been switched to lower voltage tap if needed•Blower rotates freely and shipping support has been removed•Blowerspeedtapiswiredtodesiredfanspeed(SeeBlowerPerformanceDatatables,page14-15)•Airfilteriscleanandinposition•Service/accesspanelsareinplace•Returnairtemperatureisbetween50-80°Finheatingand60-95°incooling•Aircoiliscleanwithacleanfilter•IfunitisequippedwiththeFX10Controller,theFX10ApplicationGuide(AGFX10)hasbeenreferenced.•

Startup StepsInitiate a control signal to energize the blower motor. Check blower operation.1. Initiate a control signal to place the unit in the cooling mode. Cooling set point must be set below room temperature.2.Cooling will energize after a time delay.3.

Preventive Maintenance

Water Coil/Desuperheater Coil MaintenanceKeepallairoutofthewater.Anopenloopsystemshouldbecheckedtoensurethatthewellheadisnotallowingairto1. infiltratethewaterline.Waterlinesshouldalwaysbeairtight.Keep the system under pressure at all times. It is recommended in open loop systems that the water control valve be 2. placed in the discharge line to prevent loss of pressure during off-cycles. Closed loop systems must have positive static pressure; otherwise air vents may draw air into the system.
