5.4 Selection of installation
location
Indoor unit
The indoor unit is designed for horizontal wall
installation above doors. However, it can also be
used in the upper wall area (min. 1.75m above the
floor).
Outdoor unit
The outdoor unit is designed for horizontal installa-
tion 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. The
outdoor unit can be set up outside as well as inside
a building. For external installation, please observe
the following notes to protect the unit from the
influence of the weather.
Rain
For floor or roof set-up, the unit should be installed
with at least 10cm ground clearance. A floor
bracket is available as an optional accessory.
Sun
The condenser on the outdoor unit emits heat.
Exposure to sunlight further increases the temper-
ature of the fins and reduces the heat released by
the finned heat exchanger. The outdoor unit should
be installed on to the north side of the building
whenever possible. If necessary, take measures to
provide sufficient shade (responsibility of cus-
tomer). One possible solution is to build a small
roofed area over the unit. These measures should
not affect the flow of warm outlet air.
Wind
If the unit is being installed in windy areas, ensure
that the warm outlet air is discharged in the pre-
vailing wind direction. If this is not the possible, it
may be necessary to install a windbreak (to be pro-
vided by the customer). Ensure that the windbreak
does not adversely affect the air intake to the unit.
An additional stabilization is recommended. This
can, for example, be realized with ropes or other
structures.

Snow
The unit should be wall-mounted in areas of heavy
snowfall. Installation should be at least 20cm
above the expected level of snow to prevent snow
from entering the outdoor unit. An optional wall
bracket is available as an accessory.

Installation inside buildings
n
Ensure that heat can dissipate adequately
when placing the outdoor unit in cellars, lofts,
adjoining rooms or halls (Fig. 23).
n
Install an additional fan with a rated flow com-
parative to that of the outdoor unit being
installed in the room and which can compen-
sate any additional pressure loss in ventilation
n
Comply with any regulations and conditions
affecting the statics of the building. If neces-
sary, fit acoustic installation.
