DANGER
During all work on the opened unit, substances that are harmful
to health can be released from the filter elements and come into
contact with persons.
Any released dusts must be removed with an extraction device
that has at least the same filter class as this unit and is
equipped with a suitable collection device.
The storage filter elements used in the unit are not suitable for
cleaning with compressed air. If the filters are blown out with
compressed air, this will destroy the filter membrane and
release any dusts already collected.
Replacement of the pre-filter
stage
NOTICE
If the filter saturation indicator shows that the filter needs
to be replaced, as the first step it is only necessary to
replace the pre-filter stage. If the situation does not
improve after replacement, then change the main filter.
To change the filter proceed as follows:
1. Switch off the unit and disconnect the mains plug.
