4.2 Precautions in winter and in
seasonal winds
 In snowy areas or extremely cold locations, adequate pro-
tective measures must be taken to guarantee that the unit
continues functioning correctly.
 Install the outdoor unit so that snow cannot fall directly on
the unit. If snow collects on the air inlet and freezes, errors
can occur. Install a cover in areas with snowfall.
When installing the outdoor unit in areas where there is a lot

of snowfall, ensure the unit is installed at least as high as the
level of an average snowfall (average annual snowfall).
 If more than 100 mm of snow collects on the outdoor unit,
the snow must be removed prior to operation.
NOTE
The intake and outlet opening of the outdoor unit should not be
positioned against the wind if possible.

Assembly indoor unit

5.1 General

The unit should always be installed indoors on a level, smooth
wall. Maintenance work can be carried out easily from the opera-
tor side (a minimum clearance at the side is not required). This
can be ensured by maintaining a clearance of 1 m at the front.
The indoor unit should be mounted at a height of approx. 1.30 m.
It must be installed in a room protected from frost and with short
pipe runs.
NOTE
Setup and installation must be performed by an authorised specialist
company.
When installing the indoor unit, the load-bearing capacity of the
wall should be checked. On account of the acoustics, measures
for isolating possible vibrations should also be very carefully
planned in advance.
The following connections need to be established on the indoor
unit:
 Flow / return of the heating system
 Safety valve outflow
 Power supply
 Supply voltage
 Split refrigerant pipe
 Condensate drain
 Expansion vessel connection (optional)
NOTE
When removing the unit cover, it must be taken into account that the
length of the connecting cable between the control panel in the unit cover
and the controller on the contact plate is only 1.5 m. If the device cover
can only be placed further away than this when it has been removed, the
plug connection on the controller or on the control panel must first be
disconnected.
