Modes of operation
16
Depending on the model of the cooker
hood, the following options are avail-
able:
Extraction mode
The air is drawn in and cleaned by the
grease filters and directed outside.
Non-return flap
The non-return flap is designed to pre-
vent the exchange of room and outside
air taking place when the cooker hood
is switched off.
The flap is closed when the cooker
hood is switched off.
When the cooker hood is switched on,
the non-return flap opens for the cook-
ing vapours to be blown directly out-
side.
If the on-site ventilation system does
not have a non-return flap, the non-re-
turn flap supplied must be fitted in the
exhaust socket in the motor unit.
Recirculation mode
(recirculation mode cooker hoods re-
quire a conversion kit and charcoal filter
(available as optional accessories): see
"Technical Data")
The air is drawn in and cleaned first by
the grease filters and then by a charcoal
filter. The cleaned air is then recircu-
lated back into the kitchen.
