Any work on the heat pump may only be performed by authorised and qualified customer service technicians. 1.1 Important Information CAUTION! The heat pump is not attached to the wooden pallet. CAUTION! All power circuits must be disconnected from the power source prior to opening the cabinet. CAUTION! The heat pump must not be tilted more than max. 45° (in either direction). 1.2 Legal Provisions and Directives This heat pump conforms to all relevant DIN/VDE regulations and EU directives. For details refer to the EC Declaration of Conformity in the appendix. CAUTION! The electrical connection of the heat pump must be performed according to and conforming with all relevant VDE, EN and IEC standards. Beyond that, the connection requirements of the local utility companies have to be observed. Do not lift unit by the holes in the panel assemblies! CAUTION! The heat pump is to be connected to the heat source and heat distribution systems in accordance with all applicable provisions. Flush the heating system prior to connecting the heat pump. CAUTION! The supplied strainer is to be fitted in the heat source inlet of the heat pump in order to protect the evaporator against contamination. 1.3 Energy-Efficient Use of the Heat Pump By operating this heat pump you contribute to the protection of our environment. A prerequisite for an efficient operation is the proper design and sizing of the heating system and the heat source system. In particular, it is important to keep water flow temperatures as low as possible. All energy consumers connected should therefore be suitable for low flow temperatures. A 1 K higher heating water temperature corresponds to an increase in power consumption of approx. 2.5 %. Underfloor heating systems with flow temperatures between 30 °C and 40 °C are optimally suited for energy-efficient operation. CAUTION! The brine must contain at least 25 % of a frost and corrosion protection agent on a monoethylene glycol or propylene glycol basis. CAUTION! The clockwise phase sequence must be observed when connecting the load line. CAUTION! CAUTION! Commissioning of the heat pump must be performed in accordance with the mounting and operating manual of the heat pump controller. 3 PURPOSE OF HEAT PUMP BASELINE UNIT 2 PURPOSE OF THE HEAT PUMP 3 2.1 Application The brine-to-water heat pump is designed for use in existing or newly built heating systems. Brine is used as the heat carrier in the heat source system. Ground coils, ground collectors or similar systems can be used as the heat source. BASELINE UNIT The baseline unit consists of a heat pump, ready for connection, for indoor installation, complete with sheet metal cabinet, control panel and integrated controller. The refrigeration cycle contains the refrigerant R407C. Refrigerant R407C is CFC-free, non-ozone depleting and non-combustible. All components required for the operation of the heat pump are located on the control panel. The power feed for the load and control current must be fieldinstalled by the customer. The supply lead of the brine pump (to be provided by the customer) must be connected to the control panel. When so doing, a motor protecting device is to be installed, if required. 2.2 Principle of Operation The heat generated by the sun, wind and rain is stored in the ground. This heat stored in the ground is collected at low temperature by the brine circulating in the ground collector, ground coil or similar device. A circulating pump then conveys the warmed brine to the evaporator of the heat pump. There, the heat is given off to the refrigerant in the refrigeration cycle. When so doing, the brine cools so that it can again take up heat energy in the brine circuit. The collector loops including brine manifold must be provided by the customer. 1 2 3 The refrigerant, however, is drawn in by the electrically driven compressor, is compressed and "pumped" to a higher temperature level. The electrical power needed to run the compressor is not lost in this process, but most of the generated heat is transferred to the refrigerant as well. Subsequently, the refrigerant is passed through the condenser where it transfers its heat energy to the heating water. Based on the thermostat setting, the heating water is thus heated to up to 55 °C. 4 1) Condenser 2) Control panel 4 3) Evaporator 4) Compressor ACCESSORIES TRANSPORT 4 ACCESSORIES 4.1 Brine Manifold 5 The brine manifold ties the individual collector loops of the heat source system into a single main line which is connected to the heat pump. Integrated ball valves allow individual brine circuits to be shut off for venting purposes. TRANSPORT A lift truck is suited for transporting the unit on a level surface. If the heat pump needs to be transported on an uneven surface or carried up or down stairs, carrying straps may be used for this type of transport. These straps may be passed directly underneath the wooden pallet. CAUTION! The heat pump is not secured to the wooden pallet. CAUTION! The heat pump must not be tilted more than max. 45° (in either direction). For lifting the unit without pallet, the holes provided in the sides of the frame should be used. The side panel assemblies must be removed for this purpose. A commercially available pipe can be used as a carrying aid. CAUTION! Do not use the holes in the panel assemblies for lifting the unit! 5 INSTALLATION MOUNTING 6 INSTALLATION 7 6.1 General Information As a rule, the unit must be installed indoors on a level, smooth and horizontal surface. The entire base frame should thereby make close contact with the surface in order to ensure adequate sound insulation. Failing this, additional sound insulation measures may become necessary. The heat pump should be located to allow safe and easy maintenance/service access. This is ensured if a clearance of approx. 1 m in front of and to each side of the heat pump is maintained. MOUNTING 7.1 General The following connections need to be established on the heat pump: - supply/return flow of the brine system - supply/return flow of the heating system - power supply 7.2 Connection on Heating Side CAUTION! The heating system must be flushed prior to connecting the heat pump. 1m Before completing the heat pump connections on the heating water side, the heating installation must be flushed in order to remove any impurities that may be present, as well as residues of sealing material, and the like. Any accumulation of deposits in the condenser may result in a total failure of the heat pump. 1m Once the installation on the heating side has been completed, the heating system must be filled, deaerated and pressure-tested. 1m Heating water minimum flow rate The heating water minimum flow rate through the heat pump must be assured in all operating states of the heating system. This can be accomplished, for example, by installing a differential pressure-free manifold or an overflow valve. The procedure for setting an overflow valve is described in the Chapter Commissioning. 6.2 Sound Emissions The heat pump offers silent operation due to efficient sound insulation. To prevent noise transmission to the foundation, a suitable, sound dampening rubber mat should be placed underneath the base frame of the heat pump. Any sound transmission to the heating systems is prevented by means of flexible pressure tubing already integrated into the heat pump. Frost protection for installations prone to frost Provided the controllers and circulating pumps are ready for operation, the frost protection feature of the controller is active. If the heat pump is taken out of service or in the event of a power failure, the system has to be drained. In heat pump installations where a power failure cannot be readily detected (holiday house), the heating circuit must contain a suitable antifreeze product. 6 MOUNTING 7.3 Connection on Heat Source Side An all-pole disconnecting device with a contact gap of at least 3 mm (e.g. utility company disable contactor or power contactor) as well as a 3-pole circuit breaker with simultaneous tripping of all external conductors must be provided . The required crosssectional area of the conductor is to be selected according to the power consumption of the heat pump, the technical connection requirements of the relevant utility company and all applicable regulations. Power consumption data of the heat pump is provided in the product literature and on the nameplate. The terminals are designed for a max. conductor cross-section of 10 mm˝. The following procedure must be observed when making the connection: Connect the brine line to the flow and return pipe of the heat pump. CAUTION! The supplied strainer must be fitted in the heat source inlet of the heat pump in order to protect the evaporator against the ingress of impurities. In addition, a powerful vent must be installed at the highest point of the heat source system. The hydraulic plumbing diagram must be observed here. CAUTION! The clockwise phase sequence must be observed when connecting the load line (the heat pump will deliver no output and will be very noisy when the phase sequence is incorrect). The brine liquid must be produced prior to charging the system. The brine concentration must be at least 25 %. Freeze protection down to -14°C can thus be ensured. Only antifreeze products on the basis of monoethylene glycol or propylene glycol may be used. The heat source system must be vented (deaerated) and be checked for leaks. CAUTION! The brine solution must contain at least 25 % of an antifreeze and corrosion protection agent on a monoethylene glycol or propylene glycol basis. 7.4 Electrical Connection The following electrical connections must be established on the heat pump: - Connection of the control wire to the control panel of the heat pump via terminals X1: L/N/PE. - Connection of the load wire to the control panel of the heat pump via terminals X5: L1/L2/L3/PE. - Connection of the brine pump (to be provided by the customer) to the control panel of the heat pump via terminal X1: PE and pump contactor K2: 2/4/6 (.. 5-17CS), or motor protection F7: 2/4/ 6 (.. 21CS). All electrical components required for the operation of the heat pump are located on the control panel. For detailed instructions concerning the connection and functioning of the heat pump controller refer to the operating manual supplied with the controller. 7 COMMISSIONING 8 b) Close all of the heating circuits that may also be closed during operation (depending on the type of heat pump usage) so that the most unfavourable operating state - with respect to the water flow rate - is achieved. COMMISSIONING 8.1 General Information To ensure proper commissioning it should be carried out by an after-sales service authorized by the manufacturer. Only then can an extended warranty period of 3 years in total be granted (cf. Warranty service). c) In this operating state open the overflow valve until approximately the same temperature difference exists that was measured under a) when the overflow valve was closed and the heating circuits open. Any malfunctions occurring during operation are displayed on the heat pump controller and can be corrected as described in the operating manual of the heat pump controller. 8.2 Preparation Prior to commissioning, the following items need to be checked: - All connections of the heat pump must have been made as described in Chapter 7. - The heat source system and the heating circuit must have been filled and checked. - The strainer must have been fitted in the sole inlet of the heat pump. - In the brine and heating circuits all valves that could impair the proper heating water flow must be open. - The settings of the heat pump controller must be adapted to the heating installation in accordance with the instructions contained in the controller's operating manual. 8.3 Commissioning Procedure The start-up of the heat pump is effected via the heat pump controller. CAUTION! Commissioning of the heat pump must be performed in accordance with the mounting and operating manual of the heat pump controller. Where an overflow valve is fitted to assure the minimum heating water flow rate, the valve must be set in accordance with the requirements of the heating installation. An incorrect setting may result in various error symptoms and an increased electric power consumption. To correctly set the overflow valve, the following procedure is recommended: a) Open all heating circuits and close the overflow valve. Determine the resulting temperature difference between supply and return flow. 8 CARE/CLEANING 9 CARE/CLEANING CAUTION! Caution - Heating Technicians ! Depending on the filling water quality and quantity, in particular in the case of mixed installations and plastic pipes, mineral deposits (rust sludge, lime) may form, impairing the proper functioning of the heating installation. A reason for this is the water hardness and oxygen dissolved in the filling waters as well as additional oxygen from the air, which may penetrate via valves, fittings and plastic pipes (oxygen diffusion). As a preventive measure it is recommended that a physical water conditioner such as ELYSATOR be used. 9.1 Care The heat pump is maintenance-free. To prevent malfunctions due to sediments in the heat exchangers, care must be taken that no impurities can enter the heat source system and heating installation. In the event that operating malfunctions due to contamination occur nevertheless, the system should be cleaned as described below. 9.2 Cleaning of Heating Side The ingress of oxygen into the heating water circuit may result in the formation of oxidation products (rust). It is therefore important - in particular with respect to the piping of underfloor heating systems - that the installation is executed in a diffusion-proof manner. 9.3 Cleaning of Heat Source Side CAUTION! The supplied strainer is to be installed in the heat source inlet of the heat pump in order to protect the evaporator against contamination. Also residues of lubricating and sealing agents may contaminate the heating water. In the case of severe contaminations leading to a reduction of the performance of the condenser in the heat pump, the system must be cleaned by a heating technician. The filter screen of the strainer should be cleaned one day after commissioning, thereafter every week. If no more contamination can be noticed any more, the strainer filter can be removed in order to reduce pressure losses. According to current knowledge, we recommend cleaning with a 5% phosphoric acid solution or, in the case that cleaning needs to be performed more frequently, with a 5% formic acid solution. In either case, the cleaning fluid should be at room temperature. It is recommended that the heat exchanger be cleaned in the direction opposite to the normal flow direction. To prevent acidic cleaning agents from entering the circuit of the heating installation we recommend that the flushing device be fitted directly to the supply and return lines of the condenser. To prevent any damage caused by cleaning agent residues that may be present in the system it is important that the system be thoroughly flushed using appropriate neutralising agents. The acids must be used with great care, all relevant regulations of the employers' liability insurance associations must be adhered to. If in doubt, contact the manufacturer of the chemicals! 9 MALFUNCTIONS/TROUBLESHOOTING DECOMMISSIONING 10 MALFUNCTIONS/ TROUBLESHOOTING 11 DECOMMISSIONING 11.1 Shutdown in Summer Shutting down the heating system in summer is effected by switching the heat pump controller to the "Summer" operating mode. This heat pump is a quality product and is designed for trouble-free operation. In the event that a malfunction occurs nevertheless, you will be able to correct the problem yourself in most of the cases. Simply consult the Malfunctions and Troubleshooting table contained in the operating manual of the heat pump controller. 11.2 End-of-Life Decommissioning/ Disposal Additional malfunctions can be interrogated at the heat pump controller. Before removing the heat pump, disconnect the machine from the power source and close all valves. Environment-relevant requirements regarding the recovery, recycling and disposal of service fuels and components in accordance with all relevant standards must be adhered to. Particular attention must hereby be paid to the proper disposal of refrigerants and refrigeration oils. If you cannot correct the malfunction yourself, please contact the after-sales service agent in charge (see Warranty Certificate). CAUTION! All work on the heat pump may only be performed by an authorised and qualified after-sales service. CAUTION! All electrical circuits must be disconnected from the power source prior to opening the equipment. 10 APPENDIX 12 APPENDIX 12.1 12.1.1 12.1.2 Dimensioned Drawings Dimens'ddrawing .. 5CS - 14CS 12 Dimens'd drawing .. 17CS - 21CS 13 12.2 Equipment Data 14 12.3 Performance Curves/Pressure Losses Performance Curves .. 5CS Pressure Losses .. 5CS Performance Curves .. 7CS Pressure Losses .. 7CS Performance Curves .. 9CS Pressure Losses .. 9CS Performance Curves .. 11CS Pressure Losses .. 11CS Performance Curves .. 14CS Pressure Losses .. 14CS Performance Curves .. 17CS Pressure Losses .. 17CS Performance Curves .. 21CS Pressure Losses .. 21CS 15 16 17 18 19 20 21 22 23 24 25 26 27 28 12.3.1 12.3.2 12.3.3 12.3.4 12.3.5 12.3.6 12.3.7 12.3.8 12.3.9 12.3.10 12.3.11 12.3.12 12.3.13 12.3.14 12.4 12.4.1 12.4.2 12.4.3 11 12.4.4 12.4.5 12.4.6 12.4.7 12.4.8 Wiring Diagram Control .. 5CS to .. 17CS Load .. 5CS bis .. 17CS Terminal Diagram .. 5CS to .. 17CS Legend .. 5CS to .. 17CS Control .. 21CS Load .. 21CS Terminal Diagram .. 21CS Legend .. 21CS 31 32 33 34 35 36 12.5 Hydraulic Block Diagram 37 12.6 EC Declaration of Conformity 38 12.7 Warranty Certificate 39 29 30 Heating water supply Heat pump outlet Heating water return Heat pump inlet Heat source return Heat pump inlet Heat source supply Heat pump outlet 1 1/4" internal / 1 1/4" external thread Connections on heat source side Connections on heating side 1" internal / 1" external thread APPENDIX: 12.1 DIMENSIONED DRAWINGS 12.1.1 Dimensioned Drawing .. 5CS - 14CS 12 Heating water supply Heat pump outlet Heating water return Heat pump inlet Heat source return Heat pump inlet Heat source supply Heat pump outlet 1 1/2" internal / 1 1/2" external thread Connections on heat source side Connections on heating side 1 1/4" internal / 1" external thread APPENDIX: 12.1 DIMENSIONED DRAWINGS 12.1.2 Dimensioned Drawings .. 17CS - 21 CS 13 14 ELECTRICAL CONNECTION 5 ja Subject to technical modifications Issued 24.03.2004 See EC Declaration of Conformity 3) internal Controller internal / external internal yes 1 These data characterize the size and performance capability of the system.
