Fig.
10a-20
Traps cooking grease particles.
This must be cleaned once a month (or when the filter
saturation indication system – if envisaged on the model in
possession – indicates this necessity) using non aggressive
detergents, either by hand or in the dishwasher, which must
be set to a low temperature and a short cycle.
When washed in a dishwasher, the grease filter may discolor
slightly, but this does not affect its filtering capacity.
To remove the grease filter, pull the spring release handle.

It absorbs unpleasant odors caused by cooking.
The saturation of the charcoal filter occurs after more or less
prolonged use, depending on the type of cooking and the
regularity of cleaning of the grease filter.
In any case it is necessary to replace the cartridge at least
every four mounths (or when the filter saturation indication
system – if envisaged on the model in possession – indicates
this necessity).The charcoal filter may NOT be washed or
regenerated.
Circular charcoal filter

motor impeller, then turn clockwise.
