Operating modes
Exhaust-air mode:
■ The extractor-hood fan extracts the kitch-
en vapours and conveys them through the
grease filter into the atmosphere.
■ The grease filter absorbs the solid parti-
cles in the kitchen vapours.
■ The kitchen is kept almost free of grease
and odours.
Circulating-air mode:
■ An activated carbon filter must be fitted for
this operating mode (see Filters and main-
tenance).
The complete installation set and replace-
ment filters can be obtained from specialist
outlets.
The corresponding accessory numbers
can be found at the end of these operating
instructions.
■ The extractor-hood fan extracts the kitchen
vapours which are purified in the grease
filter and activated carbon filter and then
conveyed back into the kitchen.
■ The grease filter absorbs the grease parti-
cles in the kitchen vapours.
■ The activated carbon filter binds the odor-
ous substances.
If no activated carbon filter is installed, it is
not possible to bind the odorous substances in
the cooking vapours.
