After the transport, the transport securing device is to be re-
moved on either side at the bottom of the unit.
ATTENTION!
The transport securing device is to be removed prior to commissioning.
To remove the panelling, open the individual covers by unscrew-
ing the respective turn-lock fasteners and then gently tilting the
covers away from the device. Then lift them up out of the mount-
ings.

Installation

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 insu-
lation. Failing this, additional sound insulation measures may be-
come 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.
Neither frost nor temperatures higher than 35°C must occur in
the installation location at any time of the year.

6.2 Sound Emissions

The heat pump offers silent operation due to efficient sound insu-
lation. Any vibration transmission to the foundation or the heating
system can be largely prevented by internal sound decoupling
measures.

Mounting

7.1 General Information
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
 Temperature sensor
 power supply

7.2 Connection on Heating Side

ATTENTION!
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 re-
move 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.
Consideration must be given to the following when filling the sys-
tem:
 Untreated filling water and make-up water must be of drink-
ing water quality (colourless, clear, free from sediments)
 Filling water and make-up water must be pre-filtered (pore
size max. 5µm).
Scale formation in hot water heating systems cannot be com-
pletely avoided, but in systems with flow temperatures below
60°C the problem can be disregarded.
With medium and high-temperature heat pumps, temperatures
above 60°C can be reached.
The following standard values should therefore be adhered to
concerning the filling water and make-up water (according to VDI
2035 Sheet 1):

Heating water minimum flow rate
The minimum heating water flow rate through the heat pump
must be assured in all operating states of the heating sys-
tem. This can be accomplished, for example, by installing a dual
differential pressureless manifold.
NOTE
The use of an overflow valve is only recommended for panel heating and
a max. heating water flow of 1.3 m³/h. System faults may result if this is
not observed.
