Quiet running through sound-decoupled cooling unit, vibration-decoupled compressor and sound-insulated housing Sensor for heat sources inlet and outlet, heat pumps flow and re-turn, suction gas and condenser temperature and service water in-stalled, outdoor temperature sensor included. Refrigerant R 407 C for heating water temperatures of up to 55°C. The cooling cycle is hermetically closed.

ThermiStar S …/S Compact heating mode/active cooling The cooling function is available for the following devices: ThermiStar S 6-22 ThermiStar S 6-11 Compact DM With the active cooling version, it is possible to operate the heat pump device with a cooling function, in addition to the heating and water heating function of the standard version. The cooling function is based on a reversibly designed cooling circu-lation, i.e. the heat pump operates in reverse mode (see Fig. 11). Heat is extracted from the heating water. The generated radiant heat is absorbed by the brine liquid and transported into the ground. The separation between heating water and brine is retained. In order to avoid condensation on the pipelines, the flow tempera-ture in the cooling mode should not be selected below 18°C. With lower flow temperature, the pipelines need to be insulated in a fully diffusion-resistant manner.

CAUTION! System damage from frost! The heating water in the heat exchanger freezes. Therefore: - With active cooling it must be ensured that the

rated volume flow flows on the heating side of the plate heat exchanger. For this, a flow switch must be envisaged on site.

4.2 What is included - Heat pump including comfort controller (weather-controlled, self-

diagnosis, error memory) - From 11 kW soft-start control - Integrated electric heating insert 6 kW

6.1 Safety during assembly

WARNING! Risk of injury due to improper assembly! Improper assembly leads to serious personal injuries and property damages. Therefore: - Assembly and startup must take place by an autho-

rised heating professional. - Provide sufficient installation clearance before be-

ginning with the work. - Be careful with open components with sharp edges.



activities and secure against being turned on again.

6.2 Requirements on the erection location of the heat pump

Before doing the installation, make sure that the erection location meets the following requirements: - Operating temperature +5 °C to +30°C - Dry, frost-proof, good air supply and ventilation - No heavy dust build-up - No high humidity - No air pollution through halogenated hydrocarbons (e.g. in sol-

vents, adhesives, spray cans) - No sulphur compounds - No vibrations and shocks - Stable, smooth and horizontal surface

NOTE! In case of existing systems, a dirt filter must be in-stalled on the heating side to protect the condenser.

Systems with above average temperature loads also require consultation with MHG Heiztechnik.

ThermiStar S…/Compact 6. Assembly

39/100

WARNING! Risk of life through fire! Easily flammable materials or liquids can catch fire. Therefore: - Do not use or store explosive or easily flammable

substances (i.e. fuel, paints, paper, wood) in the area where the device is installed.

- Do not dry or store laundry or clothes in the area where the device is installed.

- Do not operate device in explosive atmosphere un-der any circumstances.

The following aspects must be taken into consideration already dur-ing the planning of the system, in addition to proper dimensioning: - Future location of the heat pump under the aspect of sound

transmission through air and structure-borne sound. The acoustics in the erection rooms with reverberating walls can increase the operating sound significantly. Countermeasure: acoustic insulation on one of the opposite wall or ceiling surfaces.

- To reduce the structure-borne sound transmission, create a sepa-rate pedestal (e.g. heavy concrete) in mounted in floating fashion (e.g. on rubber).

- A pedestal is recommended for easier maintenance and care.

NOTE! MHG Heiztechnik recommends the installation of an oil sump-pump especially if the condenser is located shut off in a room for several hours (below 12 °C) and it becomes colder than the evaporator. This condition can occur especially in combination with special so-lar systems.

NOTE! Thorough planning with adequately dimensioned heat source is especially important for reasons of operational reliability and improved working output.

NOTE! Warranty becomes void if this information is disre-garded and damages can be traced to one of the listed causes.


40/100

Planning information for heat source

The heat source for operation as a brine/water heat pump (horizon-tal absorber or vertical heating elements) must be configured in ac-cordance with the cooling capacity specified in the technical data and in consideration of the ground conditions.

CAUTION! Freezing of the heat source due to incorrect dimen-sioning (overload)! Heat source becomes unusable for a long period of time. Therefore: - In case of doubt regarding the efficiency of the sur-

face, a geothermal response test must be carried out by an appropriate professional.

CAUTION! Damage to devices through freezing! The plate heat exchanger is destroyed on the source side, if the brine freezes. Therefore: - Monitor flow with safety devices (flow switch, pres-

sure switch). - The safety devices must be installed on site. The

regulations of the responsible authorities must be complied with.

Furthermore, dirt catchers, bubble separators and a rinsing device must be envisaged.

NOTE! Warranty becomes void if this information is disre-garded and damages can be traced to one of the listed causes.

Application limits

Heating water 20-55°C with refrigerant R 407 C With the Active Cooling version, the minimum flow temperature of 7°C is possible, if the rated volume flow is maintained on the heating side.

Installation clearances

Minimum clearances according are to be complied with, so that all work (assembly, startup, maintenance) can be carried out unhin-dered. - Observe the lateral clearance to the heat pump (min. 20 cm) to al-

low access for service and inspection.


41/100

6.3 Assembly tools The assembly and maintenance of the heating system requires standard tools from the field of heating installations, cooling installa-tion technology and water systems installations.

6.4 Installation information

CAUTION! Environmental damage through substances hazard-ous to groundwater! Substances hazardous to groundwater, such as greases, oils, refrigerants, solvent-based cleaning agents and the like, can burden the ground or get in-to the sewage system. Therefore: - These substances must be collected, stored and

transported in suitable containers and be disposed off.

The regulations of the heating and plumbing trade (DVGW, DIN, etc.) and of electrotechnics (potential equalization, utility company connection conditions, DIN, VDE, etc.) must be followed in particu-lar.

Transport

NOTE! The heat pump may only be transported standing and never horizontally.

The heat pump is delivered standing on a wooden pallet. It can be transported on the pallet to the installation site. The heat pump can also be transported by 2 persons with carrying straps or transport cart.

CAUTION! Device damage through improper handling! The copper pipes can be easily bent! Therefore: - Do not hold onto the pipe! - Apply force only to the base plate or the frame!

NOTE! in case of emergencies, ring the telephone number below: +44(0)208 762 83 22 [CareChem 24] (Europe)







NOTE! For operators of equipment containing 3kg or more of refrigerant the following duties of documentation apply: - Amount and type of refrigerant - Any amounts of refrigerant refills - Any amounts of refrigerant retrieved during startup,

maintenance or final disposal - Details identifying the company or technical per-

sonnel that carried out the installation, startup, or any maintenance work

- Dates and results of all inspections The recorded information must be presented to the relevant authorities and the commission upon re-quest.

CAUTION! Water damage through condensation or humidity in the air! Extremely low temperatures at the heat source lines lead to condensation or humidity in the air and can cause water damage. Therefore: - Contact between air and heat source lines must be

prevent with diffusion-resistant sealing of the insu-lation.

- The heat source lines are to be lined with diffusion-resistant insulation which must not be damaged.

6.5 Hydraulic connection

Requirements on the heating water To prevent corrosion damage in the heating system, heating water in potable quality must be used under consideration of the require-ments according to VDI guideline 2035 "Preventing damage in warm water heating systems" / SWKI guideline 97-1 "Water quality for heating, steam, refrigeration and air conditioning systems".

NOTE! Do not use any chemical additives!

Hydraulic connections

With the hydraulic connection, it must be ensure that the correct flow directions are adhered to. At the condenser, the in-flow is at the bot-tom (heating water return to heat pump). The temperature spread of 3-4 K at the heat source and 5-7 K at the heat drop must be maintained under normal operating conditions while observing the application limits. This spread is normally achieved when the volume flows specified in the technical data are observed. In comparison to conventional combustion systems, heat pumps operate with larger mass flows. This results in larger pipe diameters and relevant pump configurations.

NOTE! In order to prevent the transmission of vibrations to the pipeline network the hydraulic connections should be designed flexibly.

The connection can occur with suitable hoses or with corrugated stainless steel pipes (see Accessories). Inside the hose, an arch of at least 90° should be envisaged.

CAUTION! Device damage through improper system setup! Water and/or glycol mixture can leak. Therefore: - In the brine system, as well as on the heating side,

safety devices and expansion containers must be installed.

The compact heat pump is a central component of the heating sys-tem. The triple-level circulation pump is integrated into the cooling module. The expansion container, with a rated volume of 12 l is included and must be installed externally. It is set to preliminary pressure of 1 bar. For conventional heating systems, the volume of the expansion con-tainer is sufficient.

NOTE! If the water quantity in the heating system is larger than 250 l, the system installation engineer must in-stall an additional expansion container at a suitable location. The operating pressure is to be set to 1.5 bar in a cold condition.

The safety valve is also integrated into the cooling module.

WARNING! Risk of scalding from water that is too hot! Hot water taps are opened without awareness of dangers. Therefore: - Drinking water temperatures must not exceed 60°C.- If necessary, a service water mixing value should

be implemented on site, in order to reduce the drinking water temperature.

6.6 Electrical connection

DANGER! Risk to life through electrical current! Contact with live supply lines can cause serious inju-ries. Therefore: - When working on the device, all supply lines must

be without current. - Make sure that all electrical parts are without cur-

rent. - The applicable VDE and utility company regulations

as well as the respective regulations and guidelines of the country of destinations must be complied with.

- The electrical connections must be inspected by a responsible technician before establishing the con-nection with the line supply.

- An external separator (e.g. main switch) must be envisaged for all electrical supply lines to the ma-chine.

- Only operate the heat pump within the implementa-tion frequency (s. chapter 5.3 Type of electricity for compressor) (in Germany 50 Hz).

CAUTION! Interferences through electrical fields! Supply lines (230 V) may interfere with sensor lines (electrical low voltage). Therefore: - Sensor and supply lines may not be routed in the

same cable conduit.

The electrical connection occurs in accordance with the circuit dia-grams in chap. 5.4. The circuit protection in the distributor (meter cabinet) must be made with a 3-pole power circuit breaker (C-characteristics) according to the output ratings of the heat pump. The potential equalization is to be connected at the M6 or M8 connecting screw marked for this purpose. Highly reliable spring clips are used as connection terminals. The clips are opened with the appropriate, included tool (small screw driver) which is inserted in the respective square opening and is then moved in the direction away from the lead intake opening.

Electrical connection for compres-sor

The connection for the supply lines from the special tariff (3c400 V, N, PE) occur directly on the motor protection switch (L1, L2, L£) and for N and PE on the relevant terminal connectors on the top-hat rail.

Source protection The volume flow in the brine circuit can be monitored and used to switch off the heat pump with inadmissible deviations, e.g. failure of the pump. For this, the flow switch needs to be connected to the freely pro-grammable EX input EX5 on the controller. The input is already pre-programmed (parameter line 5988). The control direction of contact EX5 must be switched over to "break contact" through the parame-ter line 5959. The flow switch must be connected so that current is constantly connected at the EX input. With a decline in voltage, the controller switches off the heat pump. The system pressure in the brine circuit can be monitored and used to switch off the heat pump with inadmissible deviations, specifically with leaks. For this, the pressure switch needs to be connected to the freely programmable EX input EX4 on the controller. The input is already pre-programmed (parameter line 5986). The control direction of con-tact EX4 must be switched over to "break contact" through the pa-rameter line 5987. The pressure switch must be connected so that current is constantly connected at the EX input. With a decline in voltage, the controller switches off the heat pump.

Connection of heating circuit flow switch

CAUTION! System damage from frost! The heating water in the heat exchanger freezes. Therefore: - With active cooling it must be ensured that the

rated volume flow flows on the heating side of the plate heat exchanger. For this, a flow switch must be envisaged on site.

With active cooling, the volume flow must be monitored in the heat-ing circuit. With inadmissible deviations, e.g. failure of the pump, the heat pump must be switched off. For this, the flow switch needs to be connected to the freely pro-grammable EX input EX6 on the controller. The input is already pre-programmed (parameter line 5990). The control direction of contact EX6 must be switched over to "break contact" through the parame-ter line 5991. The flow switch must be connected so that current is constantly connected at the EX input. With a decline in voltage, the controller switches off the heat pump.

7 Commissioning

7.1 Safety during startup WARNING! Risk of injury through improper operation! Improper operation leads to serious personal injuries or property damages. Therefore: - Installation and assembly must be performed by a

heating systems dealer. - Carry out all of the operating steps in accordance

with the information in these instructions. - Before starting with the work activities, make sure

that electrical and hydraulic lines are shut off and secured against inadvertent opening.

- Use only suitable tools.







ThermiStar S…/Compact 7. Operation Startup

61/100

7.2 Inspection prior to startup Make sure of the following after proper assembly: - the electrical connection has been correctly installed. - the polarity of the line connection is correct - electrical voltage is applied - the heating system and possibly existing reservoir are correctly

filled and ventilated. - the correct installation of all required safety devices was made. - proper circulation of the heating water and hot water circuit exists - refrigerant lines are covered with diffusion-resistant insulation,

without any gaps - all attachments, suspensions, etc. are fastened properly and have

been verified as to their proper height

NOTE! After installation and prior to startup of the system, the protective earth resistance and the insulation re-sistance must be tested according to DIN VDE 0701 and DIN VDE 0702 and documented. These tests need to be repeated according to the applicable local time intervals or according to the DIN VDE - regulations, series DIN VDE 0701 and 0702 (repair, restarting, etc.).


62/100

7.3 Commissioning

NOTE! The customer / owner of the system must be present when starting up the system. A startup protocol is established on site.

NOTE! For operators of equipment containing 3kg or more of refrigerant, the following duties of documentation apply : - Amount and type of refrigerant - Any amounts of refrigerant refills - Any amounts of refrigerant retrieved during startup,




PRECAUTION! Risk of injury due to refrigerant! Refrigerant leakage damages the environment 100- 24,000 times more than carbon dioxide (CO2). Therefore: - Hermetically sealed systems that contain 6 kg of re-

frigerant or more must not exceed a leakage rate of 1%.

CAUTION! Device damage through wrong direction of rotation of the condenser! A reverse run over several hours or days causes se-rious damage with a loss of guarantee. Therefore: - The use of the compressor requires the correct ro-

tational direction to be set and adhered to (clock-wise rotating field).

- When turning in the wrong direction, the condenser works much louder than usual and does not pro-duce any output (compressed gas neck remains cold). A brief reverse run of a few minutes is not harmful.

CAUTION! Device damage through dry pump running. If the brine circuit is not connected or not filled, the pump can be damaged. Therefore: - The device can only be started up with a filled heat-

ing and brine circuit. Refer also to the "Startup order form".


63/100

Setting the overflow valve of the ThermiStar S Compact 06-11 DM

The internal overflow valve is set by the factory to an overflow pres-sure of 3.5 mWS (= 0.35 bar). This setting is sufficient for the con-ventional applications. With unconventionally high pressure losses in the heating circuit, the overflow pressure should be adapted so that a minimum volume flow is guaranteed within the machine with closed heating circuits, through the overflow valve. Only this way, is it ensured that no high-pressure switch-off of the heat pump or a safety switch-off by the safety temperature limit switch (STB) will occur.

NOTE! The valve must not be set to the maximum possible pressure of 6 mWS (=0.6 bar), because the functional-ity is otherwise no longer ensured.

Filling and ventilation of the ThermiStar S Compact 06-11 DM heat pump system

To prevent corrosion damage in the heating system, heating water in potable quality must be used under consideration of the require-ments according to VDI guideline 2035 "Preventing damage in warm water heating systems" / SWKI guideline 97-1 "Water quality for heating, steam, refrigeration and air conditioning systems". Do not use any chemical additives! A filling and rinsing fixture must basically be installed in the heating circuit, comprised of a shut-off device and two fill/drain valves. The heating water is preferably filled into an open container, from which it is pumped with a high-performance pump (E.g. CHI) in the flow direction through the relevant fill/drain valve into the system. The shut-off device between both of the fill/drain valves is closed. The water escapes from the 2nd fill/drain valve after flowing through the system is to be returned to the open container through a hose, so that the escaping of air is can be checked. The process should be carried out over a longer period of time, in-terrupted and repeated. (With the use of fresh water from the line, interruptions are particularly important.) When no more air escapes from the heating circuit, the fill/drain valve (outlet) must be closed and the ball valve opened, the relevant amount pump into the MAG with the pump and the system pressure set. If this has occurred, the process can be regarded as completed and the system can be ventilated again. Proceed analogously with the brine circuit!

9 Troubleshooting

9.1 Troubleshooting It is frequently noticeable that the heat pump heating systems are not operating properly because the heating circuit does not have the required volume flow. The consequence of this is the activation of safety devices on the heat pump. In case of insufficient or no flow in the heat exchange on the heating circuit side, this leads to a high-pressure disruption. It cannot be ruled out that the safety temperature limiter will also switch the sys-tem off with insufficient hot water flow. The causes of the listed faults have their origin in the periphery and in the rarest cases, in the heat pump itself. Incorrect settings on the controller can have similar effects. The activation of relevant sen-sors and the signalisation of a fault are for the protection of the sys-tem and are generally not an indication of a defective heat pump.

Faults and their removal

If the heat transfer is suddenly disrupted when the heat pump is running (e.g. due to standstill of circulating heat pump or closed valves), it can (due to the thermal inertia of the system) occur that the high-pressure safety limit switch in the heat pump is activated. The heat pump is thereby shut off and an automatic restart is pre-vented for safety reasons.

NOTE! Reduction of the service life of the high-pressure -safety limit switch, as well as the compressor, through excess wear and tear. Therefore: - If the high-pressure limit switch is activated, check

and rectify the cause. Another possible reason for triggering this high pressure safety limi-ter may also be related to the local conditions of the heat pump's in-stallation site which may necessitate the installation of an oil sump heater (strip heater on the condenser) or a "pump-down function".

Course of action for malfunctions

If electrical errors (e.g. defective sensors) can be ruled out, begin with checking the circulation pump and valves of the heating system and heat source.

NOTE! If all errors can be ruled out on the external system, the cooling cycle of the heat pump must be checked by an authorized technician.

10. Warranty ThermiStar S…/Compact

82/100

Warranty The ThermiStar heat pump by MHG renders its perfect function only when installed and started professionally. Warranty conditions of MHG can be taken from the warranty certifi-cate.

Spare parts

NOTE! Use only original MHG spare parts in case of re-placements: Some components have been designed and manufactured especially for MHG devices. Al-ways specify the serial number when ordering spare parts.

PRECAUTION! Device damage from the use of incorrect compo-nents! Using parts not manufactured/supplied by MHG can cause material decomposition. Therefore: - Only parts specified by MHG must be installed in

the cooling unit.

Warranty claim for wearing parts

(See recommendation EHI European Heating Industry, information bulletin 14) The spare parts list also contains "spare parts" that must be re-placed when the device is used as intended within the warranty pe-riod. The warranty periods have been extended by law makers, however, this does not preclude possible wear and tear from operation. It is known that a device may operate up to 8,760 hours a year when used as intended if this is a permanent operation system. According to customary commercial treatment, the costs incurred in these con-ditions are not covered by the warranty obligation or commitment of the manufacturer. The components listed in the spare parts list have been divided into the following categories: 1. Spare parts Spare parts are used for the repair of products

a) Parts are replaced that have not reached the expected ser-vice life although the device was operated as intended.

b) Furthermore, parts that are replaced due to improper opera-tion or unintended use (e.g. wrong burner settings, water flow to low or too high, boiler scale through unsuitable filling water, etc.).


83/100

2. Wearing parts Wearing parts are such parts which must be replaced sever-

al times within the scope of service life while the product is used as intended (e.g. during maintenance).

3. Auxiliary materials Auxiliary materials are required with the repair and mainten-

ance of devices. Typical auxiliary materials are, for example, seals of all kinds,

hemp, lead oxide red or fuses. Auxiliary materials are not subject to any warranty claims, except

the necessary use in the context of replacing parts in the frame-work of an existing warranty claim.

Warranty certificate MHG provides warranty for compliance with explicitly promised properties, for non-defective construction and manufacturing as well as for flawless material in the manner that the parts which have become unusable as a result of such defects or where there usefulness was significantly compromised are delivers as new at their own costs and risk. MHG provides warranty for replaced parts to the same extent as for the original delivery item. The following warranty periods apply for the Thermistar heat pump:

- 2 years material warranty on all electrical and other components , as well as on the heat pump function.

The ordering party can only assert warranty claims from MHG if the startup of the delivered item was performed by staff of MHG, companies trained by MHG or a qualified refrigeration company, the order-ing party has observed the MHG regulations of the handling and maintenance of the delivered item, the prescribed inspections were done properly and no spare parts of third-party origin were installed. The complete and current delivery and warranty conditions can be taken from the MHG price list, on the back of the order confirmations, delivery notes and invoices as well as in the Internet at www.mhg.de. Per request, MHG can send the current general delivery and warranty conditions as printout via postal service. MHG Heiztechnik GmbH

10.2 Manufacturer Certificate / EU Design Conformity Declaration

Manufacturer Certificate Buchholz i.d.n., 24.02.11 MHG Heiztechnik GmbH hereby certifies the following for the heat pumps listed below: The heat pumps are equipped with different safety circuit devices for pressure limitation in the refrigerant cycle in compliance with DIN 32733. The refrigerant cycle is accommodated by the closed housing of the heat pump. The high pressure guard safety limit switch shuts off the condenser automatically if the pressure of the medium in the refrigerant cycle exceeds 26 bar. The refrigerants R407C and the cooling equipment machine oil (diester oil) are environmentally compatible. According to the EU safety data sheet, the refrigerant R407C consists of 23% difluoromethane (HFKW 32), 25% pentafluoroethane (HFKW 125) and 52% tetrafluoroethane (HFKW 125). The RVS 61 heat pump controller used by MHG in the system is equipped with sensors for the recording and control of the source outlet temperature and the heating flow temperature. If temperatures reach levels endan-gering the system, the heat pump is shut off automatically. MHG Heiztechnik GmbH
