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 indicated lter, the appliance stops operating and the
appliance is locked.
When the appliance is locked, the lter replacement light of that
particular lter will stay on constantly.
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 and it will continue
counting the lifetime of the previous lter. As a result, the lter
replacement light will start ashing sooner than it should.
