– Sufficient load bearing capacity (for weight of the appliance,
see chapter Data table [} 66] )
A plasterboard or metal framed wall is inadequate. Additional
measures such as a double skin or additional supports are
needed in such cases.
The installation room must have an adequate condensate drain
with siphon.
The type and location of the outside air intake must ensure that
the least polluted outdoor air in the area of the building and
surroundings is drawn in.
ü The outside air intake for controlled mechanical ventilation
must be at least the following height above ground level:
700 mm.
u In addition, you must observe the minimum suction height
from the standard applicable to you.
u Avoid outdoor air intake in locations with polluted air:
– car parks and roads
– under bushes and trees
– in the proximity of waste containers
– locations contaminated with microorganisms, dust or ash

Mounting the appliance
Unpacking the appliance
u Remove the packaging.
u Put the accessories supplied aside for use later.
u To position the appliance on its underside, carefully tilt the
appliance forwards over the lower edge at the back.
Fitting the wall mounting bracket
u Hold the wall mounting bracket supplied at the required in-
stallation location as an installation template. The text "TOP"
must be at the top.
≥300
D0000115554
u Maintain the minimum clearances in order to ensure
trouble-free operation of the appliance and to allow enough
space for maintenance work.

6.3
The condensate hose may contain only one siphon. The con-
densate must be able to drain freely downstream of the siphon.
The pipes of the domestic sewer system must not rise down-
stream of the siphon. The condensate drain must be free from
the risk of frost.
A float switch prevents condensate from reaching live parts in
≥300
the unit. If the condensate hose is installed incorrectly, the float
switch cannot prevent the uncontrolled leakage of condensate.
To ensure the unit is airtight, there may be no interruption in
the condensate drain between the unit and the trap. Use the
condensate hose and mounting bend supplied as standard de-
livery.
The condensate hose must be connected to the "Condensate
drain" (d45) connection on the exhaust air side of the appliance.
Right-hand version (delivered
condition)
Left-hand version
There is a thermal insulation part in the recess surrounding the
"Condensate drain" connection.
Installation (qualified contractors)
u NOTICE: If the appliance is not mounted horizontally, con-
densate cannot drain properly. Condensate escaping in an
uncontrolled manner can damage the floor or items in the
vicinity of the appliance. For reasons of hygiene, no con-
densate must remain in the appliance. Mark the drilling
locations on the wall with a pencil through the slots and
holes on the wall mounting bracket.
u Drill the holes.
u Secure the wall mounting bracket with suitable fixing ma-
terials (screws, rawl plugs).
u Use the slots to compensate for any inaccuracies in the drill
holes.
u Align the wall mounting bracket horizontally.
u If necessary, screw the star grips included in the standard
delivery into the back of the appliance at the bottom to act
as spacers.
u Fit the appliance onto the hooks of the wall mounting
bracket.
u If the appliance is not horizontal, screw the star grips in or
out by a small amount.
Connecting the condensate hose
NOTICE
Property damage
Condensate escaping in an uncontrolled manner can
damage the floor or items in the vicinity of the unit.
u Do not kink or twist the condensate hose during
fitting.
u Arrange the condensate hose with a minimum
fall of 10 %.
u Drain the condensate into the domestic sewer system.
u Remove the condensate seal from connection "Condensate
drain".
u Pull the thermal insulation part down and out.
u Slide the thermal insulation part onto the condensate hose.
