Extraction mode or recirculation mode?
IMPORTANT: YOU WILL HAVE TO DECIDE BEFORE
INSTALLING YOUR COOKER HOOD WHETHER TO USE
IT IN EXTRACTION MODE OR RECIRCULATION
MODE.
What is the difference between extraction and recirculation
modes?
In extraction mode, the stale air will be taken via the grease filter and
out of the room via external ducting.
In recirculation mode stale air is taken via the grease filter, and passed
through a charcoal filter for purification. The air then re-enters the
kitchen via an opening in the hood.
For optimum performance, we recommend that the cooker hood is
used in extraction mode and connected to external ducting.
Unfortunately if you live in a flat or the hood is too far from an outside
wall, this may not be possible. The only alternative is to recirculate the
air.
Recirculation: Extraction:
Do I need a charcoal filter?
All cooker hoods have a grease filter but if you are using your cooker
hood in recirculation mode, then charcoal filters must be fitted in
addition to the grease filter.
