Appliance description
Instructions for use:
Operating modes
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.
DWhen 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:
❑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 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.

Before using for the first time
Important notes:
❑The Instructions for Use apply to several
versions of this appliance. Accordingly,
you may find descriptions of individual
features that do not apply to your
specific appliance.
❑This extractor hood complies with all
relevant safety regulations.
Repairs should only be carried out by
qualified specialists.
Improperly executed repairs can give

Do not flambé food directly under the
extractor hood.
Risk of grease filter catching fire due
!to flames.
Restrictions apply to the use of the
extractor hood over a solid-fuel burner
(coal, wood, etc.). (See Installation
instructions).
Gas hobs / gas cookers
Always use gas hobs in a proper and
safe manner.

Grease filters:
Metal filters are used to trap the greasy
element of the vapours that develop
during cooking.
The filter mats are made from non-
combustible metal.
Caution:
As the filter becomes more and more
saturated with grease, not only does the
risk of it catching fire increase but the
efficiency of the extractor hood can also be
adversely affected.
Important:
By cleaning the metal grease filters at
appropriate intervals, the possibility of them
catching fire as a result of a build-up of heat
such as occurs when deep-fat frying or
roasting is taking place, is reduced.
Saturation indicator:
When the grease filters reach saturation
point, an acoustic signal is sounded for 10
seconds after the fan has switched off, and
an #appears in the display. The grease
filters should be cleaned straight away.
Cleaning the metal grease filters:
❑The filters can be cleaned in a
dishwasher. It is however possible that
they will become slightly discoloured.
Important:
Metal filters that are saturated with
grease should not be washed together
with other dishes etc.
❑When cleaning the filters by hand, soak
them in hot soapy water first of all.
Then brush the filters clean, rinse them
thoroughly and leave the water to drain off.
Removing and inserting the metal grease
filters:
Warning: The halogen bulbs must be
switched off and cool.
1. Press the catch on the grease filters
inwards and fold the filters down.
Filters and maintenance
2. Clean the filters.
3. Insert the clean filters back into the
hood.
4. Cancel the #in the display.
❑Press the Lbutton for at least
3 seconds.
The #is cancelled.

9
Activated carbon filter:
For neutralizing odours in recirculating
mode.
Saturation indicator:
When the activated carbon filter reaches
saturation point, an acoustic signal is
sounded for 10 seconds after the fan has
switched off, and a ãappears in the
display. The activated carbon filter should
be replaced straight away.
Removing the filter:
Warning: The halogen bulbs must be
switched off and cool.
1. Remove the metal filters.
2. Press the catches at both sides of the
filter inwards and lift the carbon filter
down and out.
Filters and maintenance
3. Engage the catches at both sides.
4. Insert the metal grease filters (see
"Removing and inserting the metal
grease filters").
5. Cancel the ãin the display.
❑Press the Lbutton for at least
3 seconds.
The ãis cancelled.
3. Insert the metal grease filters.
Replacing the activated carbon filter:
❑A replacement filter can be obtained
from any authorized dealer (see optional
accessories).
❑Use original filters only.
By doing so you will obtain maximum
performance from your extractor hood.
Disposing of the old activated carbon
filter:
❑There are no pollutants in the activated
carbon filters. They can therefore be
disposed of as part of your normal
domestic refuse.
Inserting the filter:
Warning: The halogen bulbs must be
switched off and cool.
1. Remove the metal filters
(see "Removing and inserting the metal
grease filters").
2. Insert the activated carbon filter.

10
Cleaning and care
Disconnect the extractor hood from the
electricity supply by pulling out the
mains plug or switching it off at the fuse
box.
❑At the same time as you clean the
grease filters, clean off any grease from
all accessible parts of the housing. This
significantly reduces the fire hazard and
ensures that the extractor hood
performs as effectively as possible.
❑Use a hot detergent solution or a mild
window cleaner to clean the canopy of
the extractor hood.
❑Do not scrape off any dirt that has dried
on but loosen it up with a damp cloth.
❑Do not use abrasive cleaning agents or
sponges that could cause scratches.
❑Note: Do not use alcohol (spirit) on
plastic parts, otherwise the surface may
become matt in appearance.
Caution: Ensure that the kitchen is ade-
quately ventilated. Avoid naked flames!
Clean the operating buttons with a mild
soapy solution and a soft, damp cloth only.
Do not use stainless-steel cleaner to clean
the operating buttons.
Stainless steel surfaces:
❑Use a mild non-abrasive stainless steel
cleaner.
❑Clean the surface in the same direction
as it has been ground and polished.
Do not use any of the following to clean
stainless steel surfaces: abrasive sponges,
cleaning agents containing sand, soda, acid
or chloride!
Aluminium and plastic surfaces:
❑Use a soft, non-linting window cloth or
micro-fibre cloth.
❑Do not use dry cloths.
❑Use a mild window cleaning agent.
❑Do not use aggressive, acidic or caustic
cleaners.
❑Do not use abrasive agents.
4. Re-insert the bulb ring.
5. Plug the appliance into the mains or
switch it on at the fuse box.
Note: If the light does not function, check
that the bulbs have been inserted correctly.
Replacing the light bulbs
1. Switch off the extractor hood and pull
out the mains plug or switch off the
electricity supply at the fuse box.
When switched on, the halogen bulbs
become very hot. Even for some time after
the bulbs have been switched off there is
still a risk of burns.
2. Remove the bulb ring with a screwdriver
or similar tool.
3. Replace the halogen light bulb
(conventional halogen bulb, 12 Volt,
max. 20 Watt, G4 cap).
Caution: Refer for plug-in lampholder.
Take hold of the bulb with a clean cloth.
