Filter maintenance
This appliance is equipped with the Healthy air protect lock to ensure that
the lters are in optimal condition when the appliance is operating.
When one of the lters is almost full and has to be cleaned or replaced,
the appropriate lter replacement light starts to ash. When you do
not replace the multi-layer lter, the appliance stops operating and the
appliance is locked.
When the appliance is locked, the lter replacement light of the lter
concerned lights up on continuously.
Note: Only replace a lter when the lter replacement light ashes. If you
replace the lter before the lter replacement light starts ashing, the lifetime
counter will not be reset but will continue counting the lifetime of the previous
lter. As a result, the lter replacement light will start ashing much too soon.
Filter replacement lights
The lter replacement lights indicate which lter has to be cleaned or
replaced.
- Filter replacement light 1 ashes: lter 1 (the pre-lter) has to be
cleaned. See chapter ‘Cleaning’ for further instructions.
- Filter replacement light 2 ashes: the multi-layer lter has to be
replaced.
