Extraction Mode or Recirculation Mode
IMPORTANT: You will have to decide prior to installing your rangehood 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 rangehood.
For optimum performance, we recommend that the rangehood is used in extraction mode
and connected to external ducting.
Unfortunately if you live in a flat, or if the rangehood is too far from an outside wall, this may
not be possible. The only alternative is to recirculate the air.
• What is a charcoal filter and do I need one?
All rangehoods have a grease filter but if you are using your rangehood in recirculation
mode, then a charcoal filter (Part Number: STI) must be fitted in addition to the grease filter.
