Selecting the installation location
The unit is designed for horizontal
installation on a base in outdoor
areas. The installation site must be
level, flat and firm. The unit should
also be secured to prevent it from
tipping over.
For external installation, please
observe the following instructions
to protect the unit from
the influence of the weather.
It is also possible to install
the unit in the interior of
the building. However, in this case
the circulation of the required air
flow volume (see technical data)
must be assured. Any change
to the air flow volume can result
in faults or damage to the unit.
Rain
The unit should be at least 10 cm
off the ground when mounted on
the roof or ground.
Sun
The finned condenser gives
off heat in cooling mode.
Exposure to sunlight further
increases the temperature of
the fins and reduces the heat
released by the finned heat
exchanger.
The unit should, whenever
possible, be installed on the north
side of the building.
If necessary, take measures
to provide sufficient shade
(responsibility of customer).
This could be a small roof.
However, the discharging warm
air flow must not be affected by
the measures.
Wind
If the unit is being installed
inwindy areas, ensure that
the warm outlet air is discharged
in the prevailing wind direction.
If this is not possible, it may be
necessary to install a windbreak
on-site
(Figure 3)
.
Ensure that the windbreak does
not adversely affect the air intake
to the unit.

Minimum clearance to snow
Snow
The unit should be wall-mounted
in areas of heavy snowfall.
Installation should be at least
20 cm above the expected
level of snow to prevent snow
from entering the outdoor unit

Installation inside buildings (cooling mode)
Sun
The finned condenser gives off
heat in cooling mode.
Exposure to sunlight further
increases the temperature
of the fins and reduces the heat
released by the finned heat
exchanger.
Cooling capacity changes as
a consequence of ambient
conditions influenced by rain, sun,
wind, and snow, for example.
