INSTALLATION MOUNTING

5INSTALLATION

5.1 General

The unit should always be installed on a permanently level, smooth and horizontal floor. The entire base frame surface should thereby make close contact with the floor in order to ensure adequate sound insulation and to prevent water-carrying parts from cooling out. If this is not the case, additional insulation measures may become necessary. It must be possible to carry out servicing work without any problems. This is ensured if a clearance of 1.2 m to solid walls is maintained.

CAUTION! The intake and discharge openings must not be restricted nor obstructed.

5.2 Condensate Line

The condensation water that may collect during operation must be drained in a place protected from frost. The heat pump must be positioned horizontally so that proper discharge can be ensured. The condensation water pipe must have a minimum diameter of 50 mm and should be discharged to the sewer drain in a frost-proof location.

6MOUNTING

6.1 General

The following connections need to be established on the heat pump:

-supply/return flow of heating system

-supply/return flow of hot water circuit

-condensate drain

-control lead to the heat pump controller

-power supply

6.2 Heating and Hot Water Connection

The connections on the heating side of the heat pump are provided with 1"external thread. The hoses to be connected exit the unit through its bottom. When carrying out the connections, use a wrench to counterhold at the transitions.

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 and to ensure trouble-free operation of the heat pump. On systems equipped with heating water flow shut-off devices such as radiator or thermostat valves, an overflow valve to be provided by the customer needs to be installed behind the heating pump in a heating system bypass. This guarantees a minimum heating water flow through the heat pump and prevents any malfunctions from occurring.

Once the installation on the heating side has been completed, the heating system must be filled, de- aerated and pressure-tested.

Frost Protection

As a precaution against frost, manual drain valves should be provided. If the heat pump is placed out of service or in the event of a power failure, the system has to be drained at three points (see figure) and blown out. In heat pump installations where a power failure cannot be readily detected (holiday house), the heating circuit must contain a suitable antifreeze product.
