Operation Instructions

Operating modes

Exhaust-air mode:
❑ The extractor-hood fan extracts the kit-
chen vapours and conveys them
through the grease filter into the atmos-
phere.
❑ The grease filter absorbs the solid
particles in the kitchen vapours.
❑ The kitchen is kept almost free of grease
and odours.
Circulating-air mode
❑ An activated carbon filter must be fitted
for this operating mode (see Filters and
maintenance).
Activated carbon filters can be
purchased from specialist outlets
(see Optional accessories on the last
page).
❑ The ventilator fan draws the vapours
produced during cooking into the
extractor hood, where they pass
through the grease filter and the activa-
ted carbon filter before the clean air is
discharged back into the kitchen.
❑ The grease filter absorbs the grease
contained in the vapours produced
during cooking.
❑ The activated carbon filter absorbs any
odorous substances.

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 boi-
lers) 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.
If no activated carbon filter is installed,
it is not possible to bind the odorous
substances in the cooking vapours.

Risk of grease filter catching fire due
to flames.
❑ Before using your appliance for the first
time, please read these Instructions for
Use carefully. They contain important
information concerning your personal
safety as well as on use and care of the
appliance.
❑ Please retain the operating and
installation instructions for a subsequent

The hotplates must always be covered
with a utensil.
Restrictions apply to the use of the
extractor hood over a solid-fuel burner
(coal, wood, etc.). (See Installation
instructions).
Gas hobs / Gas cookers
Do not use all the gas hotplates
simultaneously for a prolonged period
(max. 15 minutes) at maximum thermal
load, otherwise there is a risk of burns if
the housing surfaces are touched or a risk
of damage to the extractor hood. If the
extractor hood is situated over a gas hob,
operate the hood at maximum setting if
three or more gas hotplates are operated
simultaneously.
