Assembly

6.1 General

The following connections need to be established on the heat
pump:
Flow and return of the heating system

Control lines to the heat pump manager

 Voltage supply
Condensate drain

All panelling can be removed to allow accessing the inside of
the device.
Loosen the screws for this purpose. The panels can be removed
toward the top when slightly tilted.

6.2 Connection on the heating side

The heating system connections on the heat pump are to be
made inside the device. Refer to the device information for the
connection sizes. Route the connection hoses out of the device
in a downwards direction. An optional pipe kit is available as an
accessory, which can be used to lead the connections out to
the side. Use a spanner to firmly grip the transitions when con-
necting 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 could cause the heat pump to completely break down.
Once the heat pump has been connected to the heating sys-
tem, 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 sediments)
Filling water and make-up water must be pre-filtered (pore

size max. 5 µm).
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. 6.1: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.
