9. Preparations
9.1 Sound emissions
The appliance is louder on the air intake and air discharge sides
than on the two enclosed sides. Take the following information
into account when selecting the installation location.
Note
For details regarding the sound power level, see chapter
"Specification / Data table".
9.1.1 Sound emissions for outdoor installation
- Lawn areas and shrubs help reduce the spread of noise.
- Noise propagation can also be reduced through dense pali-
sades or similar.
f
f
Ensure that the entire appliance frame is in full contact
with the substrate. Uneven substrates can increase sound
emissions.
f
f
Ensure that the air intake direction is the same as the dom-
inant wind direction. Air should not be drawn in against the
wind.
f
f
Ensure that the air intake and air discharge are never direct-
ed towards noise-sensitive rooms of the house, e.g. bed-
rooms, or neighbouring houses.
f
f
Avoid installation on large, echoing floor areas, e.g. tiled
floors.
f
f
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.
f
f
Ensure that the entire appliance frame is in full contact
with the substrate. Uneven substrates can increase sound
emissions.
f
f
Never install the appliance directly below or next to a living
room or bedroom.
f
f
Never direct the air intake and discharge apertures in exter-
nal walls towards neighbouring windows or living rooms/
bedrooms.
f
f
Protect pipe outlets through walls and ceilings with anti-vi-
bration insulation.

f
f
Never install the appliance in a recess. Two sides of the ap-
pliance must remain exposed.
f
f
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.
f
f
Ensure that the appliance is not fully enclosed by objects
such as buildings, walls or fences.
If the air discharge side of the appliance faces the wall of a house,
the cool air from the air discharge may cause condensate to form
on this wall.
!
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.
f
f
Ensure that the minimum air flow rate is maintained
(see chapter “Specification / Data table”).
