Installation
6.1 General Information
The following connections need to be established on the heat
pump:
Fresh and exhaust air
Flow and return flow of the heating system
Condensate outflow
Outflow for the pressure relief valve
Power supply
6.2 Air Connection
ATTENTION!
Do not restrict or block up the area around the air inlet or outlet.
The air intake opening of the device is solely designed for direct
connection to a wall opening. The wall opening can be provided
with air duct and sealing collar for this purpose. See the illustra-
tion in the appendix under Installation Dimensions.
The glass fibre reinforced concrete air ducts offered as accesso-
ries are moisture-resistant and diffusion-free.
The sealing collar is used to seal the air ducts on the heat pump.
The air ducts are not screwed directly onto the heat pump. Only
the rubber seal comes into direct contact with the heat pump
when the system is installed correctly. This guarantees easy as-
sembly and disassembly of the heat pump and also ensures that
solid-borne sound is well insulated.
It must also be ensured that the interior side of the wall opening
is lined with thermal insulation to prevent the wall from becoming
cold and to prevent moisture from penetrating the wall. The en-
closed fixing accessories can be used for attachment to the wall.

The air outlet can be optionally mounted directly to a wall open-
ing or to a longer duct (available as an accessory). Use the same
mounting procedure as for the air inlet.
If a flange-mounted air duct is used on the air outlet side, it is se-
cured with 4 M8 x 16 hexagon bolts in the threaded holes pro-
vided. When doing this, ensure that the air duct stubs only touch
the insulation. There should be no contact with the external
sheeting.
Observe the external and internal dimensions as specified in the
figure. Also ensure that the vibration and duct isolation are ade-
quate.
6.3 Heating System Connection
To enable connection to the heating system, flexible hose con-
nection pieces and double nipples with a 1" external thread are
included with the heat pump. These allow the optional use of a
threaded or flat gasket connection to the heating system.
If the heat pump is not intended to be used to heat up the hot wa-
ter, the hot water output must be permanently sealed using the
supplied sealing plug.
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.
