Choosing the installation
location
The outdoor unit is designed for
horizontal upright installation
outdoors.
The installation location for the
unit must be horizontal, flat and
stable. The unit must also be se-
cured against tipping.
The outdoor unit can be set up
either outside or inside a building.
For outdoor installation, follow
the instructions below to protect
the unit against the effects of the
weather.
Rain
For floor or roof installation, the
unit must be installed with at least
10 cm of ground clearance.
On cooling and heating units,
raised installation increases the
heating capacity produced.
A base bracket is available as an
accessory.
Sun
The fin exchanger (condenser) for
the outdoor unit is a component
that emits heat.
Sunlight increases the temperature
of the fins and thus reduces the
heat discharged by the fin ex-
changer.
Where possible, the outdoor unit
should be installed on the North-
ern side of the relevant building.
Shading should be set up if re-
quired. This can take the form of a
small roof.
However, the measures taken may
not affect the emerging flow of
hot air.
Wind
If the unit is to be installed in
windy locations, it must be en-
sured that the emerging flow
of hot air is carried away in the
prevailing wind direction. If this is
not possible, the customer should
provide wind protection. Make
sure that the wind protection does
not block the air supply to the unit.
Installation inside buildings
Ensure adequate heat dissipation if the outdoor unit is to be installed
in a cellar, loft, adjoining room or corridor.
Install an additional fan, which should have the same volumetric air
flow as the outdoor unit to be installed in the room and be capable of
compensating for any additional pressure losses caused by air ducts.
Snow
In regions with heavy snowfall,
you should install the unit on the
wall.
It should be installed at least 20 cm 20 cm20 cm
above the highest expected snow
level to prevent snow from pen-
etrating into the outdoor unit.
A wall bracket is available as an
accessory.
