Material damage
Please note that the outdoor air must be able to flow
unimpeded into the appliance, and the exhaust air must
be able to be expelled without obstruction.
If the air intake and discharge of the appliance are ob-
structed by surrounding objects, this may cause a thermal
short-circuit.
f
f
Ensure that the air intake direction is the same as the main
wind direction. Air should not be drawn in against the wind.
f
f
Ensure that the appliance is not surrounded by any objects
such as buildings, walls or fences. If necessary, maintain a
greater clearance to the surrounding objects.
f
f
Observe chapter „Sound emissions“.
!
Material damage
The air flow rate through the appliance must not fall
below the minimum level. If the air flow rate falls below
the minimum level, trouble-free operation of the appli-
ance is not guaranteed.
f
f
Ensure that the minimum air flow rate is maintained. Obser-
ve the details in chapter „Specification / Data table“.
f
f
If necessary, maintain a greater clearance to the surrounding
objects.
If the air discharge side of the appliance faces a wall of the house,
condensate may form on this wall from the cool air at the air
discharge.
Note
If the air discharge side faces house walls, maintain the
minimum specified clearance between the appliance and
the building.
9.3 Refrigerant lines
!
Material damage
Prevent dirt and moisture from penetrating the refrige-
rant circuit. For this purpose, install the refrigerant lines
just before the system is commissioned.
f
f
Keep the refrigerant lines closed until commissio-
ning.
f
f
Take appropriate measures to prevent damp outdoor
air from penetrating refrigerant lines (e.g. by filling
with dry air/nitrogen and sealing with a plug).
f
f
Point the pipe ends downwards to prevent water or
dirt entering.
f
f
Cut the pipes using suitable tools without creating
any swarf or burrs. Prevent the ingress of swarf into
the pipes.
Where possible, carry out the installation steps in one go
to prevent any contamination from entering refrigerant
lines between individual steps.
Keep the distance between the external and internal unit as small
as possible to reduce heat losses.
While the appliance is operating you may hear flow noises and
noises from the compressor, particularly during the defrosting
process.
f
f
Therefore avoid routing refrigerant lines through living areas
and bedrooms.
f
f
As much as possible, route refrigerant lines outside the buil-
ding wall.
Install both the internal and external unit in such a way that the
maximum lengths and heights of the refrigerant lines are not
exceeded.
f
f
Observe the maximum refrigerant line length and the maxi-
mum height offset.

Note
The refrigerant does not have to be topped up. The appli-
ance is pre-filled for the maximum permissible split line
length (see chapter "Specification / Data table").
