Filter replacement

Filter maintenance
This appliance is equipped with the Healthy air protect lock to ensure that

the filters are in optimal condition when the appliance is operating.

When one of the filters is almost full and has to be cleaned or replaced,

the appropriate filter replacement light starts to flash. When you do

not replace the multi-layer filter, the appliance stops operating and the

appliance is locked.

When the appliance is locked, the filter replacement light of the filter

concerned lights up on continuously.
Note: Only replace a filter when the filter replacement light flashes. If you

replace the filter before the filter replacement light starts flashing, the lifetime

counter will not be reset but will continue counting the lifetime of the previous

filter. As a result, the filter replacement light will start flashing much too soon.

Filter replacement lights
The filter replacement lights indicate which filter has to be cleaned or

replaced.

- Filter replacement light 1 flashes: filter 1 (the pre-filter) has to be

cleaned. See chapter ‘Cleaning’ for further instructions.

- Filter replacement light 2 flashes: the multi-layer filter has to be

replaced.
