Installation

6.1 General

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 25°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.

Assembly

7.1 General
The following connections need to be established on the heat
pump:
 Flow and return of the well system
 Flow / return of additional heat exchanger.
 Flow and return of the heating system
 Power supply
7.2 Connection on heating and hot
water 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.

ATTENTION!
It is recommended that the secondary side be equipped with the flow rate
switch (available as an option).
ATTENTION!
It is recommended that the primary side be equipped with the flow rate
switch (available as an option).
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

Use of the optionally available four-way reversing valve is recom-
mended. A detailed installation description can be found in the in-
structions included with the valve.
Note:
For operation of the heat pump with the four-way reversing valve,
it is essential to set up the hydraulic connections according to the
instructions included in the scope of supply of the valve. The in-
structions give a description of the precise procedure for the cor-
rect assembly of hydraulics. Non-observance of this will lead to
restrictions in the operation of the heat pump.
Important:
The notes/settings in the instructions of the heat pump manager
must always be observed and carried out accordingly; not doing
so will lead to malfunctions.
Heating water minimum flow rate
The minimum heating water flow 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 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.
