INSTALLATION MOUNTING
6INSTALLATION
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 make full 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 installed to allow easy maintenance/service access. This is ensured if a clearance of approx. 1 m in front of the heat pump is maintained.

6.2 Sound Emissions
The heat pump offers silent operation due to efficient
sound insulation. Any sound transmission to the
foundation or the heating system can be largely
prevented by internal sound decoupling measures.

7.1 General Information
The following connections need to be estab- lished 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
The sensor supplied loose in the control box must be fitted as shown in the block diagram.
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
Frost protection for installations prone to frost
Provided the controller and heating 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.
