8.11 Insert new outdoor air filter
► Carefully guide the new outdoor air
filter (item 1 in Fig. 17) into the venti -
lation unit.
► Make sure that the air filter slides into
the 3 retaining tabs (item 2 in Fig. 17)
on the back wall of the ventilation
unit.
► Place the filter cover (item 3 in
Fig. 17) on the outdoor air filter. Make
sure that the filter cover lies flat on
the intermediate plate (item 4 in
Fig. 17).
► Turn the filter cover clockwise until
the arrow on the filter cover (item 5 in
Fig. 17) lines up with the arrow for the
locking position (item 6 in Fig. 17). Make sure that the 3 tabs (item 7 in Fig. 17) on the
filter cover engage in the retainers (item 8 in Fig. 17) on the intermediate plate.
► Check the position of the filter cover. The hand grip must be vertical and the arrow
on the filter cover must line up with the arrow for the locking position (see Fig. 7 on
page 13).
