Installation

6.1 General Information

The compact brine-to-water heat pump must be installed in a
frost-free, dry room on an even, smooth and horizontal surface.
The entire base of the frame should lie directly on the floor to en-
sure an adequate soundproof seal. The surface must have suffi-
cient load bearing capacity for the weight of the heat pump and
the domestic hot water quantity. If supporting feet are used, the
heat pump must be installed horizontally. In this case, the speci-
fied sound level can be up to 3 dB(A) higher, and additional
sound insulation measures may be necessary.
The heat pump must be installed so that maintenance work can
be carried out without hindrance. This can be ensured by main-
taining a clearance of approx. 1 m in front of and, where neces-
sary, at the sides of the heat pump. If the heat pump is accessed
from the front (e.g. installed in a recess etc.), the heat pump mod-
ule can be removed for after-sales service (see Chapter 5).
Neither frost nor temperatures higher than 35 °C must occur in
the installation location at any time of the year.

6.2 Acoustic Emissions

The heat pump operates silently due to efficient sound insulation.
Internal insulation measures should be carried out to prevent vi-
brations from being transmitted to the foundation or to the heat-
ing system.

7.2 Connection on heating side

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
liquefier may cause the heat pump to completely break down.
Once the heat pump has been connected to the heating system,
it must be filled, de-aerated and pressure-tested.
The maximum test pressure in the heating circuit and the brine circuit is
6.0 bar.
This value must not be exceeded.
The following points must be observed when filling the system:


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 re-
garding the filling and make-up water according to VDI 2035,
sheet 1:
Minimum heating water flow
The minimum heating water flow through the heat pump must be
assured in all operating states of the heating system.
This can be achieved using a heating circuit which is continu-
ously open, e.g. in a reference room which is regulated using a
room temperature controller (available as a special accessory).
(see integration diagram Fig.5.1 on pag. XVIII)
NOTE
System faults may result if this is not observed.

ATTENTION!
ATTENTION!
Untreated filling water and make-up water must be of drink-
ing water quality.
(colourless, clear, free of sediments)
Filling water and make-up water must be pre-filtered (max.
pore size 5 µm).
