6.2 Condensate pipe
Condensed water 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 di-
rectly into clearing tanks or cess pits. The aggressive vapours
and a condensate pipe laid in an area which is not frost-free can
destroy the evaporator.
ATTENTION!
The frost line can vary according to the climatic region. The regulations
of the countries in question must be observed.

Assembly
7.1 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.

7.2 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 system,
it must be filled, de-aerated and pressure-tested.
