INSTALLATION
PREPARATIONS
9. Preparations
9.1 Acoustic emissions
On the air intake and air discharge sides, the appliance is louder
than on the enclosed sides. Observe the following information
when selecting the installation location.
Note
For details regarding the sound power level, see chapter
"Specification / Data table".
9.1.1 Sound emissions for external installation
- Lawn areas and shrubs contribute to the reduction of noise.
- Noise propagation can also be reduced through dense pali-
sades or similar.
Ensure that the air intake direction is in line with the main
wind direction. Air should not be drawn in against the wind.
Never direct the air intake or discharge towards noise-sensi-
tive rooms of the house, e.g. bedrooms.
Avoid installation on large, echoing floor areas, e.g. tiled
floors.
Avoid installation between reflective building walls. Reflec-
tive building walls can increase the sound level.
9.1.2 Sound emissions for internal installation
- Never install on joists.
Never install the appliance directly below or next to living
rooms or bedrooms.
Never direct the air intake and discharge apertures in exter-
nal walls towards neighbouring windows or living rooms/
bedrooms.

Do not install the appliance in a recess. Two sides of the ap-
pliance must remain exposed.
Maintain the minimum clearances to ensure trouble-free op-
eration of the appliance and facilitate maintenance work.
In order to prevent air "short circuits", maintain the minimum
clearances in the case of surrounding structures and in par-
ticular in the case of cascades. Maintain the flow rate on the
heat source side (see chapter "Specification / data table ").

Damage to the appliance and environment
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.
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.

Damage to the appliance and environment
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.
Ensure that the minimum air flow rate is maintained. Ob-
serve the details in chapter "Specification / Data table".
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.
