To clean the coarse lter, hold button 1 in
so that the inlet valve closes and the airow
into the coarse lter container ceases. The
side duct fan then starts to build up a greater
negative pressure.
Keep button 1 held in and then press but-
ton 2 to open the cleaning valve and clean
the coarse lter.
On the display, check that the desired
lter status is achieved after cleaning.
Otherwise, clean again.
If the lter status is above 30%,
dust is stuck in the lter and the lter
must be cleaned or replaced. See Filter
