•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.
When the extractor hood is operated in exhaust-
air mode simultaneously with a different burner
which also makes use of the same chimney (such
as gas, oil or coal-fired heaters, continuous-flow
heaters, hot-water boilers) care must be taken to
ensure that there is an adequate supply of fresh
air which will be needed by the burner for
combustion.
Safe operation is possible provided that the
underpressure in the room where the burner is
installed does not exceed 4 Pa (0.04 mbar).
This can be achieved if combustion air can flow
through non-lockable openings, e.g. in doors,
windows and via the air-intake/exhaust-air wall box
or by other technical measures, such as reciprocal
interlocking, etc.
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
•Installation accessories for circulating air
mode.
Ventilation duct
AD280/281-126 for ceiling heights of
2.44–2.76 m
AD280/281-136 for ceiling heights of
2.76–2.98 m..
•An activated carbon filter must be fitted for this
operating mode (see Filters and maintenance).
•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.
몇If no activated carbon filter is installed, it is not
possible to bind the odorous substances in the
cooking vapours.

Coanda effect
•You do not need to activate the Coanda effect.
The Coanda air flow is always active at every
fan level. Cooking vapours are extracted
particularly well at the front of the cooking field.
•The Coanda effect may allow you to operate the
extractor hood at a lower, quieter level than you
were previously accustomed to.
•The Coanda air flow exits the top of the
extractor hood’s front panel. Do not place any
objects on the extractor hood: these may
disrupt the Coanda effect.
