INSTALLATION MOUNTING

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.
6.2 Sound Emissions
The heat pump offers silent operation due to efficient sound insulation. Noise transmission to the foundation or the heating system is largely prevented by internal decoupling measures.
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 space heating and water heating system
-common return of space heating and water heating system
-return, overflow valve
-connection for additional expansion vessel (as required)
-drain lines of overflow valves
-condensate drain
-power supply
7.2 Heating-Side Connection
The heat pump features separate outlets for the space heating and water heating circuit.
In cases where the heat pump has no water heating mode, the hot water outlet has to be permanently sealed.
Prior to establishing 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, or the like. Any accumulation of deposits in the condenser may result in a total failure of the heat pump.
In systems equipped with heating water flow shut- off devices such as radiator or thermostat valves, an overflow valve is installed. This assures a minimum heating water flow through the heat pump and prevents any malfunctions for occurring.
Once the installation on the heating side has been completed, the heating system must be filled, deaerated and
Frost Protection for Installations Prone to Frost
Provided the controller and the heating circulating pumps are ready for operation, the frost protection function of the controller is always activated. If the heat pump is taken out of service or in the event of a power failure, the system must be drained. In heat
