The appliance can be installed to recirculate
or extract contaminated air.
Recirculation
The cooker hood is supplied specified for use
in the recirculation mode with the charcoal filter
fitted.
The contaminated air is cleaned by passing
through the filters and then back into the
kitchen.
Extraction
The contaminated air enters the hood passing
through the grease filter and out through the
ducting into the atmosphere.
When the extraction mode is selected the
charcoal filter is not required.
Never do flambé cooking under this
cooker hood.
Take extra care when frying and never
leave frying pans unattended during
use as over-heated fats and oils might
catch fire.
Do not leave naked flames under the
cooker hood.
Ensure the visor is open when using the
hob even if the fan on the hood is not
switched on.
Ensure heating areas on your hob are
covered with pots and pans when using
the hob and cooker hood
simultaneously.
