CAUTION!
For installation close to walls the physical influences of the
building must be considered. No windows or doors should be
present in the area surrounding the air outlet of the ventilator.
CAUTION!
In cases of installation close to a wall, there may be more
sediment in the air inlet and outlet areas due to the air current.
The colder outside air outlet should discharge in such a way as
to not increase the heat losses in heated neighbouring rooms.
CAUTION!
Installation in a hollow or in an inner courtyard is not
permitted because cooled air collects at ground level and is
drawn in again by the heat pump during lengthy operation.
5.2 Condensate pipe
Condensate that forms during operation must be drained off
frost-free. To ensure proper drainage, the heat pump must be
mounted horizontally. The condensate pipe must have a mini-
mum diameter of 50 mm and must be fed into a sewer in such
a way that it is safe from frost. Do not discharge the condensate
directly into clearing tanks or cesspits, as aggressive vapours or
a condensed water pipe which has not been laid in a frost-free
manner could destroy the evaporator.
CAUTION!
The frost line can vary according to the climatic region. The
regulations of the countries in question must be observed.

6.1 General
The following connections need to be established on the heat
pump:
Heating system flows and returns
Condensate outflow
Control line to the heat pump manager
Voltage supply
6.2 Connection on 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 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 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 sedi-
ments)
Filling water and make-up water must be pre-filtered (pore
size max. 5 µm).
