Selection of the installation location
The indoor unit is designed for
horizontal wall installation in the
upper wall area (at least 1.75
m from the upper edge - floor).
However, it can also be used in the
upperwall area above doors.
The outdoor component is
designed for horizontal installation
on a base in outdoor areas. It
should be placed on level, flat and
firm surface. The unit should also
be secured to prevent toppling.
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 weather
conditions.
Wall openings
■
A wall opening of at least
70 mm diameter and 10 mm
slope from the inside to the
outside must be made for each
indoor unit.
■
We recommend that the inside
of the opening is padded or
lined, e.g. using a PVC pipe,
to prevent the lines being
damaged.
■
After installation, the wall
opening should be closed off
with a suitable sealant. Do not
use materials containing cement
or lime!
Installation material
The indoor unit is attached with
4 screws on the building side,
through the
back wall of the unit.
The outdoor unit is attached with
4 screws via a wall bracket on
the wall or a floor bracket on the
ground.
Rain
The unit should be at least 10 cm
off the ground when mounted on
the roof or ground. A pedestal is
available as an accessory.
Sun
The evaporator fins (condenser)
of the outdoor unit are the
heat discharge components in
cooling operation. Exposure to
direct sunlight further increases
the temperature of the fins and
so reduces the heat released by
the finned heat exchanger. The
outdoor component should be
installed on to the north side of
the building whenever possible.
If necessary, take measures
to provide sufficient shade
(responsibility of customer).
This could be a small roof.
However, the discharging warm air
flow may not be affected by the
measures.
Wind
If the unit is being installed in
windy areas, ensure that the
warm outlet air discharges in the
main wind direction. If this is not
the case it may be necessary to
install a windbreak (provided by
the customer). 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 then be at least
20 cm above the expected level
of snow to prevent snow from
entering the outdoor component.
An optional wall bracket is
available as an accessory.
