Operating modes
Exhaust-air mode:
❑ Installation accessories for exhaust air
mode.
Ventilation duct
AD260/261-012 for ceiling heights of
2.12 – 2.65 m
AD260/261-022 for ceiling heights of
2.49 – 3.05 m.
❑ The extractor-hood fan extracts the kit-
chen 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.
D
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
AD260/261-112 for ceiling heights of
2.23 – 2.65 m
AD260/261-122 for ceiling heights of
2.49 – 3.05 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.
ṇ If no activated carbon filter is installed,
it is not possible to bind the odorous
substances in the cooking vapours.
