Operating modes

Exhaust-air mode:
q The extractor-hood fan extracts the kitchen
vapours and conveys them through the grease
filter into the atmosphere.
q The grease filter absorbs the solid particles in
the kitchen vapours.
q The kitchen is kept almost free of grease and
odours.
If the extractor hood is operated in exhaust-
air mode at the same time as a flue-type heater
(e.g. gas, oil or solid-fuel heater, instantaneous
water heater, boiler), ensure that there is an
adequate air supply which the heater requires for
combustion.
Safe operation is possible provided that the partial
vacuum in the room in which the heater is installed
does not exceed 4 Pa (0.04 mbar).
This can be achieved if the combustion air is able to
flow through non-lockable openings, e.g. in doors,
windows and in conjunction with an air supply/
air-intake wall box or by other technical procedures
such as reciprocal interlocking.

Operating modes
Light / fan
switches If the air intake is inadequate, there is a risk of
poisoning from combustion gases which are
drawn back into the room.
An air-intake/exhaust-air wall box by itself is no
guarantee that the limiting value will not be ex-
ceeded.
Note: When assessing the overall requirement, the
combined ventilation system for the entire house-
hold must be taken into consideration. This rule
does not apply to the use of cooking appliances,
such as hobs and ovens.
Unrestricted operation is possible if the extractor
hood is used in recirculating mode – with activated
carbon filter.
Circulating-air mode:
q An activated carbon filter must be fitted for this
Filter grille
operating mode (see Filters and maintenance).
The complete installation set and replacement
filters can be obtained from specialist outlets.
The corresponding accessory numbers can be
found at the end of these operating instructions.
q The extractor-hood fan extracts the kitchen va-
pours which are purified in the grease filter and
activated carbon filter and then conveyed back
into the kitchen.
q The grease filter absorbs the grease particles in
the kitchen vapours.
q The activated carbon filter binds the odorous
substances.
If no activated carbon filter is installed, it is
not possible to bind the odorous substances in the
cooking vapours.
