work is complete, switch on the power
supply to the fan-and-filter unit.
The fan-and-filter unit operates automati-

once the power has been switched on.

7 Changing the filter
7.1 Installing the filter media
The fan-and-filter unit and outlet filter are
supplied as standard with a standard filter
mat for the pre-filtering of dry, coarse dust
and lint. In order to increase the protection
category, and in the case of dust with a
grain size of < 10 µm, we recommend the
use of fine filter mats (optionally available).
Depending on the incidence of dust, you
will need to replace the filter mat from time
to time.
• Use your finger to pull the function logo
in the louvred grille upwards slightly
to
unlock it. The grille will now flip open by
about 70° to allow the filter mat to be re-
placed easily.

• Insert the filter mat into the louvred grille
as shown in Fig. 7 and push the louvred
grille back onto the enclosure until it
snaps audibly into position.

Caution!
Only change the filter mat
while the fan wheel is
stationary.
Never insert your fingers into
the fan wheel.
Note:
The progressive side of the filter
mat is pointing towards the fan
wheel.
