Installation

5.1 General

The device should always be installed on a permanently smooth,
even and horizontal surface. The entire frame should lie directly
on the ground to ensure a good soundproof seal and to prevent
the water-bearing components from becoming too cold. If this is
not the case, additional insulation measures may be necessary.
Furthermore, the heat pump should be set up so that the air out-
let direction of the ventilator is perpendicular to the main wind di-
rection to allow unrestricted defrosting of the evaporator. It must
be possible to carry out maintenance work without hindrance.
This is ensured when observing the distances to solid walls as
shown in the figure.
The specified dimensions are valid for stand-alone installation
only.
ATTENTION!
Do not restrict or block the area around the air intake or outlet.
ATTENTION!
Observe country-specific building regulations!
ATTENTION!
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.
ATTENTION!
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.
ATTENTION!
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

Condensed water that forms during operation must be drained
off frost-free. To ensure proper drainage, the heat pump must be
mounted horizontally. The condensed water pipe must have a
minimum diameter of 50 mm and should be fed frost-free into a
sewer. Condensate should not be discharged directly into clear-
ing tanks and cesspits because the aggressive vapours could
destroy the evaporator.

Assembly

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
Power 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.
ATTENTION!
The dirt trap included in the scope of supply is to be installed in the heat
return before the heat pump.
Cleaning and maintenance instructions can be found in the dirt
trap's installation and operating instructions.
Once the heat pump has been connected to the heating system,
it must be filled, de-aerated and pressure-tested.
Consideration must be given to the following when filling the sys-
tem:
Untreated filling water and make-up water must be of drink-
ing water quality (colourless, clear, free from sediments)
Filling water and make-up water must be pre-filtered (pore
size max. 5µm).
Scale formation in hot water heating systems cannot be com-
pletely avoided, but in systems with flow temperatures below
60°C the problem can be disregarded.
With medium and high-temperature heat pumps, temperatures
above 60°C can be reached.
The following standard values should therefore be adhered to
concerning the filling water and make-up water (according to VDI
2035 Sheet 1):
