4.2.3 Air extraction mode
The air is expelled to the exterior through the exhaust air duct. For this reason, the room must be
equipped with an air exhaust duct leading to the outside of the building.
WARNING: If the hood operates in extraction mode and there are combustion systems
in operation (e.g. a solid fuel stove), the room in which the appliance is installed must be
supplied with a sufficient flow rate of fresh air at all times. Always seek the advice of a
qualified technician.
WARNING: If a permanently installed air exhaust duct or flexible air extraction duct is not
available, the hood must be operated in recirculation mode.
4.2.4 Recirculation mode
The air drawn in by the hood is filtered through a charcoal filter (also called an activated carbon filter)
and then returned to the room. The charcoal filter removes cooking odours from the air. The filtered air
is returned to the kitchen through the side or top air vents. If the hood is used in recirculation mode,
simultaneous operation of a fireplace is of no concern in relation to air quality.
NOTICE: Switch the appliance on a few minutes before you start cooking.
Leave the fan running for 5-10 minutes once you have finished cooking, on both the extraction version
and the recirculation version. This precaution removes residual vapour and odours from the air in the
kitchen.
- For improved performance of the hood, remove the vapour collector (if present).
- Adjust the fan speed in accordance with the quantity of fumes or vapour to be removed.
- Only switch the hood off about 5-10 minutes after you finish cooking.
- Replace the vapour collector (if present).
