The coarse fi lter must be cleaned once a week. To do this, proceed as
follows:
1. Pull the cover of the air inlet from the device, as shown in Fig. 47.
2. Slide
the fi lter cassette out from the cover of the air inlet, as shown
in Fig. 48.
3. Remove the coarse fi lter (black) from the fi lter cassette.
4. Clean the fi lter with mild soapy water. Do not use any other agents!
5. Rinse the fi lter thoroughly with clear water.
6. Let the fi lter dry completely in the air.
Instead of cleaning the fi lter, you can insert a new one or replace the entire
fi lter cassette with a new one.
The white fi ne fi lter cannot be cleaned. It should be inspected visually
weekly and replaced monthly or more frequently if heavily soiled. To do
this, proceed as follows:
1. Pull the cover of the air inlet from the device, as shown in Fig. 47.
2. Slide
the fi lter cassette out from the cover of the air inlet, as shown
in Fig. 48.
3. Remove the coarse fi lter (black) from the fi lter cassette.
4. Remove the fi ne fi lter and replace it with a new one.
