Installation
6.1 General Information
The unit must be installed indoors on a level, smooth and hori-
zontal 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.
6.2 Acoustic Emissions
The heat pump operates silently due to efficient sound insulation.
To prevent vibrations from being transmitted to the foundation, a
suitable, sound dampening rubber mat should be placed under-
neath the base frame of the heat pump.
To prevent any sound from being transmitted to the heating sys-
tem, we recommend connecting the heat pump to the heating
system by means of hose sections.

Installation
7.1 General Information
The following connections need to be established on the heat
pump:
Flow and return flow of the brine system
Flow and return flow of the heating system
Power supply
Outflows for the pressure relief valves
7.2 Heating System Connection
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, de-
aerated and pressure-tested. The pressure indicator is located
on the control panel.
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 heat pump is ready for operation. If the heat pump
is taken out of service or in the event of a power failure, the sys-
tem 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).
The integrated expansion vessel has a volume of 8 litres. The
volume should be checked by the heating system engineer. In-
stall an additional expansion vessel if necessary.
ATTENTION!
In the case of large-volume heating circuits, use an additional expansion
vessel to supplement the installed expansion vessel.
