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.

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.

(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.

11
Setting the saturation indicator
If it becomes necessary to change the
operating mode (exhaust-air/recirculating
mode), the saturation indicator for the filters
must also be altered (see Installation
Instructions).
If you encounter a problem
If an #or ãappears in the display:
❑See "Filters and maintenance" Section.
If is not possible to operate the extractor
hood:
❑Disconnect the extractor hood from the
mains electricity supply by pulling out the
plug or switching it off at the main fuse
box.
Wait for approx. 1 minute and then
switch it on again.

Important information
Installation Instructions:
The installation of the extractor hood
above gas cooking devices, at a
minimum height of 650 mm – Fig. 1 – is
permitted provided that the following
nominal heat loads (Hs) are not exceeded:
❑Gas cookers
Load of one hotplate max. 03.0 kW
Load of all hotplates max. 08.3 kW
Load of the oven max. 03.9 kW
❑Gas hobs
Load of one hotplate max. 03.9 kW
Load of all hotplates max. 11.3 kW
❑Gas glass-ceramic hotplate
The data on nominal heat loads do not
apply to gas glass-ceramic hotplates.
Be sure to observe the instructions
provided by the manufacturer of the
hotplate.
❑Solid-fuel cookers
The maximum nominal heat loads and
the minimum distance are the same as
for gas cookers.
Installation of the extractor hood over a
solid-fuel burner which could constitute a
potential fire hazard (e.g. due to flying
sparks) is only permitted if the burner is
equipped with an enclosed, non-
removable cover and all country-specific
regulations are observed. This restriction
does not apply to gas cookers and gas
hobs.
The smaller the gap between extractor
hood and hob, the greater the likelihood
that rising steam will cause condensation
to form on the hood.
Old appliances are not worthless
rubbish. If they are disposed of in an
environment-friendly manner, valuable raw
materials can be recovered for use again.
Before you dispose of an old appliance,
make sure that it has been rendered
inoperative.
Your new appliance was protected on
its way to you by the packaging. None of
the materials cause pollution to the envi-
ronment and all can be recycled for use
again. Please help to protect the
environment and dispose of the packaging
in an environment-friendly manner.
You can obtain information about the best
method disposing of old appliances and
packaging from your dealer or local
municipal council.
The extractor hood can be used in
either exhaust-air or recirculating mode.
Always mount the extractor hood over
the centre of the hob.
Minimum distance between electric
hob and bottom edge of extractor hood:
550 mm, Fig. 1.
Additional notes concerning gas
cookers:
When installing gas hotplates, comply
with the relevant national statutory
regulations (e.g. in Germany: Technische
Regeln Gasinstallation TRGI).
The relevant regulations and installation
notes provided by the manufacturer of the
gas cooker must be observed in all cases.
The extractor hood may be installed
next to only one full-height cupboard or
high wall. Gap to be at least 50 mm.

13
Prior to installation
The exhaust air is discharged upwards
through a ventilation shaft or directly
through the outside wall into the open.
DExhaust air should neither be directed
into a smoke or exhaust flue that is
currently used for other purposes, nor into
a shaft that is used for ventilating rooms in
which stoves or fireplaces are also located.
Exhaust air may be discharged in
accordance with official and statutory
regulations only (e.g. national building
regulations).
Local authority regulations must be
observed when discharging air into smoke
or exhaust flues that are not otherwise in
use.
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.
If the exhaust air is going to be
discharged into the open, a telescopic
wall box should be fitted into the outside
wall.
