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 New home 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 New home filter has to be

replaced.
