WARNING Risk of injury when working at
heights due to falling slide-in module (2.5 kg).
Sometimes the slide-in module is hard to pull out
of the wall sleeve/slide into the wall sleeve. Use
appropriate, certified climbing aids (ladders). Sta-
bility should be ensured, if necessary have the
ladders steadied by a 2nd person. Ensure that
you are standing securely and cannot lose your
balance and that there is no one under the unit.
When installing and removing the slide-in mod-
ule, support it from below with a hand.
CAUTION Risk of injury from insects
(wasps, bees etc.) in the external cover or
wall sleeve.
Watch out for small animals when removing the
slide-in module. Recommendation: Use units in
continuous operation.

CAUTION Cuts due to sharp edges on
sheet metal or housing cut-outs or on the
slide-in module.
Wear protective gloves. Do not damage connec-
tion cables.

diseases, infections due to poor hygiene if

ATTENTION
• Change the air filters of the ventilation unit
when the filter change indicator appears (rap-
idly flashing LEDs).
• Never operate the ventilation unit without an air
filter. The ventilation unit becomes dirty and un-
filtered substances can enter the rooms.
• Generally, change the internal and external fil-
ters together.
• Only use original air filters with the prescribed
filter class. Otherwise there is a danger to
health from harmful substances that can accu-
mulate in the air filter.
• Change the air filters regularly, after 6 months
at the latest.
• Replace the air filters even after the ventilation
unit has not been used for a longer period of
time.
