Modes of operation

The cooker hood works with

. . . air extraction:

The air is drawn in and cleaned by the

grease filters and directed outside.

If the on-site ventilation system does

not have a non-return flap, the

non-return flap supplied with the

appliance must be fitted in the exhaust

socket in the motor unit.

Having a non-return flap fitted in the

ducting ensures that air, once ducted

to the outside, cannot get back into the

room again.

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

cooking vapours to be ducted away.

. . . air recirculation:

(available as an optional extra with a

conversion kit and charcoal filter: 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

recirculated back into the kitchen

through grilles in the top of the cooker

hood extension piece.

Before using the cooker hood in

recirculation mode, ensure that the

charcoal filter is in place. See

"Cleaning and care".
