MAINTENANCE
The regenerable active carbon filters can be washed by hand or in the
dishwasher at a maximum temperature of 65 °C. The washing cycle
must be done without other dishes and without dishwasher detergent.
Do not use any cleaning agents!
Remove excess water. Be careful to avoid damaging the filter. Place the
filter in the oven to dry for at least 1 hour at a maximum temperature of
80 °C. After up to 3 years (or if the filtres are damaged), the filters will
need to be replaced.
It is important that the grease filters and the regenerable active
carbon filters are properly dried before installation.
