Changing the air filters
12.3.1 Removing the cover from the ventilation unit
► Using both thumbs, press the two
latches (item 1 in Fig. 18) on the
bottom of the ventilation unit. The unit
cover will come away.

fingers into the gap between the unit

to the unit must be switched off
using the building’s miniature circuit
breaker.

using the hand grip (item 2 in Fig. 19)
anti-clockwise until the filter ring is
released from the retainers.
► Pull the filter ring together with the
extract air filter (item 3 in Fig. 19) out
of the ventilation unit.
► Detach the extract air filter from the
filter ring.
► Clean the filter ring with a damp cloth
if it is dirty (see section 13).
