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:
❑This requires installation of an activated
carbon filter (see section on filter and
maintenance).
❑The activated carbon filter is obtainable
as a special accessory from your
authorized dealer.
❑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.
If no activated carbon filter is installed,
it is not possible to bind the odorous
substances in the cooking vapours.
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.
If the extractor hood is operated in
exhaust-air mode at the same time as a
flue-type heater (e.g. gas, oil or solid-fuel
heater, instantaneous water heater, boiler),
ensure that there is an adequate air
supply, which the heater requires for
combustion.
Safe operation is possible provided that the
partial vacuum in the room in which the
heater is installed does not exceed 4 Pa
(0.04 mbar).
This can be achieved if the combustion air
is able to flow through non-lockable
openings, e.g. in doors, windows and in
conjunction with an air supply/air-intake
wall box or by other technical procedures
such as reciprocal interlocking.

Filters and maintenance
Different grease filters can be used to
absorb the grease particles in kitchen
vapour.
Fleece grease filter:
The filter mat consists of highly
flameresistant material.
Attention:
A build up of greasy residue increases
flammability, and the function of the
extractor hood may be impaired.
Important:
Replace the fleece grease filter in good
time, otherwise there is a risk of fire from
the heat which accumulates during deep-
fat frying or roasting.
Replacing the fleece grease filter:
❑During normal operation (daily 1 to 2
hours) the fleece grease filter must be
replaced every 8 to 10 weeks.
❑Replace printed fleece grease filters at
the latest when the coloured print
dissolves.
Only use original filters.
❑These comply with the safety
regulations and ensure optimum
function.
Disposal if the old fleece grease filter:
❑Fleece grease filters do not contain any
harmful substances. They can be
disposed of as bio-degradable waste.
Metal grease filters:
The filter mats consist of non-flammable
metal.
Attention:
A build up of greasy residue increases
flammability, and the function of the
extractor hood may be impaired.
Important:
Replace the metal grease filter in good
time, otherwise there is a risk of fire from
the heat which accumulates during deep-
fat frying or roasting.
Cleaning the metal grease filters:
❑During normal operation (daily 1 to 2
hours) metal grease filters must be
replaced every 8 to 10 weeks.
❑The metal grease filter can be cleaned in
the dishwasher. Slight discoloration may
occur.
Important:
❑Do not clean heavily saturated metal
grease filters together with kitchen
utensils.
❑If cleaning by hand, soak the filter mats
in a hot soapy solution for several hours.
Then brush them off, rinse thoroughly
and leave to dry.
❑Only use original filters.
These ensure optimum function.

Faults
If you should have any questions or there
are any faults, call customer service (see
list of customer service units).
Please give the following details when you
call:
Enter these numbers in the spaces above.
You will find the numbers on the rating
plate inside the extractor hood after
removing the filter screen.
Product no. (E-Nr.)
Serial no. (FD)
Changing the bulbs
Isolate the extractor hood by pulling out
the mains plug or switching off the fuse.
❑When cleaning the grease filters, remove
grease deposits from accessible parts of
the housing. This prevents the risk of fire
and ensures that the extractor hood
continues operating at maximum
efficiency.
❑Clean the extractor hood with a hot
soap solution or a mild window cleaner.
❑Do not scrape off dried-on dirt but wipe
off with a damp cloth.
❑Do not use scouring agents or abrasive
sponges.
❑Note: Do not use alcohol (spirit) on
plastic surfaces, as dull marks may
appear.
Caution: Ensure that the kitchen is
adequately 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.
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.

Important information Before installation
Optimum efficiency of the extractor
hood:
❑Short, smooth exhaust pipe.
❑As few bends as possible.
❑Pipe diameter as large as possible
(ideally 150 mm dia.) and wide pipe
bends.
If long, rough exhaust-air pipes, many
pipe bends or smaller pipe diameters
are used, the air extraction rate will no
longer be at an optimum level and there
will be an increase in noise.
❑Round pipes
Short exhaust air pipe:
inside diameter min. 120 mm,
Longer exhaust air pipe:
inside diameter min. 150 mm.
❑Flat ducts must have an inside
cross-section equivalent to that of
the round pipes.
There should be no sharp bends.
ø 120 mm dia. approx. 113 cm2
ø 150 mm dia. approx. 177 cm2
❑If pipe diameters differ, insert sealing
strip.
❑Ensure that there is an adequate air
supply for exhaust air mode.
Old appliances are not worthless
rubbish. Valuable raw materials can be
reclaimed by recycling old appliances.
Before disposing of your old appliance,
render it unusable.
You received your new appliance in a
protective shipping carton. All packaging
materials are environmentally friendly and
recyclable. Please contribute to a better
environment by disposing of packaging
materials in an environmentally-friendly
manner.
Please ask your dealer or inquire at your
local authority about current means of
disposal.
The extractor hood can be used in
exhaust air or circulating air mode.
Always mount the extractor hood over
the centre of the hob.
The minimum distance between the
hob and the lower edge of the extractor
hood is 650 mm.
The extractor hood must not be
installed over a solid fuel cooker – a
potential fire hazard (e.g. flying sparks) –
unless the cooker features a closed, non-
removable cover and all national
regulations are observed.
The smaller the gap between the
extractor hood and hotplates, the greater
the likelihood that droplets will form on the
underside of the extractor hood.
Additional information concerning
gas cookers:
When installing gas hotplates, comply
with the relevant national statutory
regulations (e.g. in Germany: Technische
Regeln Gasinstallation TRGI).
Always comply with the currently valid
regulations and installation instructions
supplied by the gas appliance
manufacturer.
Only one side of the extractor hood
may be installed next to a high-sided unit
or high wall. Gap at least 50 mm.
