Integrated ball valves allow individual brine circuits to be shut off for venting purposes. 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. wooden pallet. 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. assemblies for lifting the unit! CAUTION! CAUTION! CAUTION! The heat pump is not secured to the The heat pump must not be tilted Do not use the holes in the panel 5 INSTALLATION MOUNTING INSTALLATION 67 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. 1m 1m 1m 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. 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. 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. Once the installation on the heating side has been completed, the heating system must be filled, de- aerated and pressure-tested. 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. 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 CAUTION! of impuritihere. es. CAUTION! 7.3 Connection on Heat Source Side The following procedure must be observed when making the connection: Connect the brine line to the flow and return pipe of the heat pump. The supplied strainer must be fitted in the heat source inlet of the heat pump in order to protect the evaporator against the ingress In addition, a powerful vent must be installed at the highest point of the heat source system. The hydraulic plumbing diagram must be observed 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 mono- ethylene glycol or propylene glycol may be used. The heat source system must be vented (de aerated) and be checked for leaks. 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 ...
