Appliance description

Operating modes

Exhaust-air mode:
❑ The extractor-hood fan extracts the
kitchen vapours and conveys them
through the grease filter into the
atmosphere.
❑ The grease filter absorbs the solid
particles in the kitchen vapours.
❑ The kitchen is kept almost free of grease
and odours.
If the extractor hood is in exhaust-air
D
mode and a flue-type heater is running
at the same time (e.g. gas, oil or solid-fuel
heaters, continuous-flow heaters, water
heaters), ensure that the fireplace has an
adequate air supply for combustion.
Safe operation requires that the low air
pressure in the room in which the fireplace
is located does not exceed 4 Pa (0.04
mbar).

Operating modes
This low air pressure can be obtained,
provided combustion air can escape
through non-lockable openings, e.g. in
doors, windows, air-intake/exhaust-air wall
boxes or by other technical procedures,
such as reciprocal interlocking, etc.
An air-intake/exhaust-air wall box by itself is
no guarantee that the limiting value will not
be exceeded.
Note: When assessing the air pressure, the
entire ventilation system in the house/
apartment must be taken into account.
If using cooking appliances, e.g. hob and/or
gas cooker, this rule does not apply.
Government regulations must be observed
for the conveyance of exhaust air.
If the extractor hood is used in circulating-
air mode – with activated carbon filter –,
there are no operating restrictions.
Circulating-air mode:
❑ An activated carbon filter must be fitted
for this operating mode (see Filters and
maintenance).
The complete installation set and
replacement filters can be obtained from
specialist outlets.
❑ The extractor-hood fan extracts the
kitchen vapours which are purified in the
grease filter and activated carbon filter
and then conveyed back into the
kitchen.
❑ The grease filter absorbs the grease
particles in the kitchen vapours.
❑ The activated carbon filter binds the
odorous substances.
