INSTALLATION
Preparations
Avoid installation between reflective building walls. Reflect-
ing building walls can increase the noise level.
9.1.2 Sound emissions for indoor 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.
9.2 Minimum clearances
9.2.1 Outdoor installation
≥500
≥1000
≥500
≥500
≥700

Never 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").
!
Material losses
Please note that both the flow of outdoor air into the
appliance, and the flow of exhaust air from the appliance
must be unimpeded.
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 fully enclosed by objects
such as buildings, walls or fences.
If necessary, maintain a greater clearance to the surrounding
objects.
!
Material losses
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 a house,
the cool air from the air discharge may cause condensate to form
on this wall.
Note
If the air discharge side faces house walls, maintain a
minimum clearance of 2m between the appliance and
the building.
9.2.2 Indoor installation

Maintain the minimum clearances to ensure trouble-free op-
eration of the appliance and facilitate maintenance work.
9.3 Substrate
General information
Ensure that the appliance is accessible from all sides.
Ensure that the base is level, even, solid and permanent.
Ensure the entire appliance frame is in full contact with the
substrate. Uneven substrates can increase noise emissions.
