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 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
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 exceeded.
Note: When assessing the overall
requirement, the combined ventilation
system for the entire household 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:
This requires installation of an activated
carbon filter (see section on filter and
maintenance).
The activated carbon filter is obtainable
as a special accessory from your
authorized dealer
The corresponding accessory numbers
can be found at the end of these
operating instructions.
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.
If no activated carbon filter is installed,
it is not possible to bind the odorous
substances in the cooking vapours.
