manual abstract
An external wall temperature sensor including fixing accessories and a dirt trap are supplied with the heat pump. The power feed for the load current and the control current must be installed by the customer. The supply lead of the well pump (to be provided by the customer) must be connected to the switch box. It is important to ensure that the integrated motor protection is sufficient for the pump provided by the customer. 1 2 A lift truck is suited for transporting the unit on a level surface. Carrying straps may be used if the heat pump needs to be transported on an uneven surface or carried up or down stairs. These straps can be passed directly underneath the wooden pallet. A ATTENTION! A ATTENTION!_ The heat pump must not be tilted more than 45° (in any direction). Use the holes provided in the sides of the frame to lift the unit without the pallet. The side panel assemblies must be removed for this purpose. Any commercially available length of pipe can be used as a carrying aid. A ATTENTION!_ Do not use the holes in the panel assemblies for lifting the device! 1) Evaporator 2) Switch box 3) Liquifier 4) Compressor E-3 English English 5 5 Set-up 5.1 General Information The unit may only be installed indoors in rooms with low humidity on a level, smooth and horizontal surface. The entire base of the frame should lie directly on the floor to ensure a good soundproof seal. If this is not the case, additional sound insulation measures may be necessary. The heat pump must be installed so that maintenance work can be carried out without being hindered. This can be ensured by maintaining a clearance of approx. 1 m in front of and on each side of the heat pump. 5.2 Sound Emissions The heat pump operates silently 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. To prevent any sound from being transmitted to the heating system, we recommend connecting the heat pump to the heating system by means of hose sections. 6 Installation 6.1 General Information The following connections need to be established on the heat pump: ■ Flow and return flow of the well system ■ Flow and return flow of the heating system ■ Power supply 6.2 Heating System Connection A ATTENTION!_ Flush the heating system prior to connecting the heat pump. Before connecting the heating water system to the heat pump, the heating system must be flushed to remove any impurities, residue from sealants, etc. Any accumulation of deposits in the liquifier could cause the heat pump to completely break down. Once the heating system has been installed, it must be filled, deaerated and pressure-tested. Minimum heating water flow rate The minimum heating water 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 either a manifold without differential pressure or an overflow valve. The procedure for adjusting an overflow valve is described in the Chapter Start-up. Antifreeze protection for installation locations prone to frost The antifreeze function of the heat pump controller is active whenever the controller and the heat circulating pumps are ready for operation. If the heat pump is taken out of service or in the event of a power failure, the system has to be drained. The heating circuit should be operated with a suitable antifreeze if heat pump systems are implemented in buildings where a power failure can not be detected (holiday home). 6.3 Heat Source Connection The following procedure must be observed when connecting the heat source: Connect the well pipes to the heat pump flow and return flow. A ATTENTION!_ The well water must comply with the required water quality standards. The hydraulic plumbing diagram must be adhered to. E-4 7.3 6.4 Electrical Connection The following electrical connections need to be established on the heat pump. ■ Connection of the control line to the control panel of the heat pump via terminal X1: L/N/PE. ■ Connection of the mains cable to the control panel of the heat pump via terminal X5: L1/L2/L3/PE. ■ Connection of the mains cable of the well pump to the control panel of the heat pump via terminal X5: L11/L21/L31/PE. ■ Connection of the well pump (to be provided by the customer) to the control panel of the heat pump via terminal X1: PE and pump contactor K5: 2/4/6. Ensure that the supply voltage for these terminals cannot be switched off by the tariff contactor when connecting the mains cable of the well pump, in order to enable the turn-off delay of the well pump. 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 (e.g. external wall sensor included in the scope of supply), refer to t...
