Selection of the installation 
location

Indoor unit

The indoor unit is designed for 
horizontal wall installation above 
doors. However, it can also be 
used on the upper wall area  
(min. 1.75 m from upper edge of 
floor).

Outdoor component

The outdoor component is 
designed for horizontal base 
installation outdoors. It should 
be placed on level, flat and firm 
ground. The unit should also 
be secured to prevent toppling. 
The outdoor component 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 hole is padded or 
lined, e.g. using a PVC tube, 
to prevent the pipes being 
damaged.

■ 

After installation, the wall 
opening should be closed off on 
the building side with a suitable 
sealant.  Do not use substances 
containing cement or lime!

Installation material

The indoor unit is fastened using a 
wall bracket and 4 threaded screws 
(provided by the customer). 

The outdoor component is 
attached with 4 screws via a wall 
bracket on the wall or a floor 
bracket on the ground.

Minimum clearance to snow

20 cm

Snow

Windbreak

Wind

Pipes and cables in wall breakthrough

Control cable

Condensation pipe

Injection pipe

Suction pipe

PVC tube

Rain

 

The unit should be at least 10 cm 
off the ground when mounted on 
the roof or ground. A floor bracket 
is optionally available.

Sun

The liquefier on the outdoor 
component radiates heat.
Exposure to direct sunlight will 
further increase the temperature 
of the fins and reduce the 
heat output of the finned 
heat exchanger. The outdoor 
component should therefore be 
installed as near as possible to 
the north side of the building. 
If necessary, take measures 
to provide sufficient shade 
(responsibility of customer). One 
possible solution is to build a small 
roof. 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 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.

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 component. 
An optional wall bracket is 
available as an accessory.
