Set-up

6.1 General Information

The brine-to-water heat pump must be installed in a frost-free,
dry room on an even, smooth and horizontal surface. The entire
frame should lie directly on the floor to ensure an adequate
soundproof seal and to prevent the water-bearing components
from becoming too cold. 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 hindrance. This can be ensured by main-
taining a clearance of approx. 1 m in front of and on each side
of the heat pump.
NOTE
The heat pump is not intended for use over 2000 metres
above sea level.
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 insula-
tion. Internal insulation measures should be carried out to pre-
vent vibrations from being transmitted to the foundation or to
the heating system.

7.2 Heating System Connection

The heat pump is equipped with separate outputs for the heat-
ing circuit and the hot water circuit.
If the heat pump is not intended to be used to heat up the hot
water, the hot water output must be permanently sealed.
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.
An overflow valve is installed in the device for systems in which
the heating water flow can be shut off via the radiator or ther-
mostat valves. This ensures a minimum heating water flow rate
through the heat pump and helps to avoid faults.
Once the heating system has been installed, it must be filled,
de-aerated and pressure-tested.
Consideration must be given to the following when filling the
system:
Untreated filling water and make-up water must be of

drinking water quality (colourless, clear, free from sedi-
ments)
Filling water and make-up water must be pre-filtered (pore

size max. 5µm).
Scale formation in domestic hot water heating systems cannot
be avoided, but in systems with flow temperatures below 60 °C,
the problem can be disregarded. With high-temperature heat
pumps and in particular with bivalent systems in the higher per-
formance range (heat pump + boiler combination), flow tem-
peratures of 60 °C and more can be achieved. The following
standard values should therefore be adhered to with regard to
the filling and make-up water according to VDI 2035, sheet 1:
The total hardness values can be found in the table.

pumps.
Fig. 7.1:Guideline values for filling and make-up water in accordance with
VDI 2035
For systems with an above-average specific system volume of
50 l/kW, VDI 2035 recommends using fully demineralized
water and a pH stabiliser to minimize the risk of corrosion in the
heat pump and the heating system.
CAUTION!
With fully demineralized water, it is important to ensure that
the minimum permissible pH value of 7.5 (minimum
permissible value for copper) is complied with. Failure to
comply with this value can result in the heat pump being
destroyed.
