Intended use
This extractor hood complies with the
stipulated safety regulations. Improper use
may result in injury or damage.
The extractor hood may be used in the
household only. The manufacturer is not liable
for damage which is caused by improper use or
incorrect operation.
The manufacturer cannot be made
responsible for damage which can be attributed
to non-observance of the safety instructions.
RISK OF INJURY
Do not allow children to play with the
extractor hood! Adults and children must
never operate the appliance unsupervised
– if they are not physically or mentally
capable of doing so,
– or if they do not have the knowledge and
experience to operate the appliance
correctly and safely.
Technical safety
The extractor hood left the factory in perfect
condition. Nevertheless check the appliance for
visible damage before installation. If it is
damaged, do not switch it on!
If the power cord of the extractor hood is
damaged, it must be replaced by the
manufacturer, his customer service or a
similarly qualied person to prevent hazardous
situations.
Only a qualied technician may install
(including electrical connection), service or
repair the extractor hood. Always isolate the
extractor hood by pulling out the mains plug
or switching o the fuse!
 Safety instructions
If the appliance is improperly installed,
serviced or repaired, the user may be placed in
considerable danger for which the
manufacturer is not liable.
Changes to the electrical or mechanical
installation are dangerous and must not be
undertaken! They may also cause the extractor
hood to malfunction.
Simultaneous operation of the extractor
hood with a heating appliance which is
dependent on ambient air
Heating appliances which are dependent
on ambient air, e.g. gas, oil, wood, or solid-fuel
heaters, instantaneous water heaters, hot
water boilers, hobs or ovens, and which draw
combustion air out of the installation room
and whose exhaust gases are conveyed to the
exterior by a ue.
RISK OF POISONING
If the extractor hood is operated at the same
time as a heating appliance which is
dependent on ambient air, there is a risk of
poisoning due to combustion gases being
drawn back in.

6
Safe operation is possible provided the low
pressure in the installation room of the heating
appliance does not exceed 4Pa (0.04mbar).
This can be achieved if the combustion air can
ow through non-closable openings, e.g. in
doors, windows, in conjunction with air
intake/exhaust air wall boxes or by other
technical measures.
Adequate intake air must therefore always
be provided.
An intake/exhaust air wall box alone does not
ensure compliance with the limit value.
NOTE: When making your evaluation, always
consider the entire ventilation system in the
home. Include the advice of a competent
heating engineer when making your
evaluation.
If the extractor hood is used in circulating
air mode only, it can be operated without any
restrictions.
Special information for gas cookers
When installing the extractor hood above
gas hobs, observe the appropriate national
statutory regulations (e.g. in Germany:
Technische Regeln Gasinstallation TRGI).
Observe the currently valid installation
regulations and instructions of the gas
appliance manufacturer.
During installation, ensure that only one side
of the extractor hood is situated directly next to
a high-sided unit or a wall. Otherwise, there is a
risk of heat build-up. The gap between the
extractor hood and the wall or high-sided unit
must be at least 50 mm.
RISK OF BURNS
Do not operate more than 2 gas cooking areas
simultaneously over a period of max.
15 minutes at maximum thermal load. Due to
the eect of the heat there is a risk of burns if
the surfaces of the housing are touched!
Note that one large burner of more than
5 kW (Wok) is equivalent to the power of 2 gas
burners.
The extractor hood may be damaged by
the intense heat.
Never operate a gas cooking area without a
cooking utensil on it. Regulate the ame in
such a way that it does not project over the
cooking utensil.

Safety instructions
Proper use
Clean the extractor hood thoroughly before
using for the rst time.
Before cleaning and servicing the extractor
hood, isolate it from the power supply by
pulling out the mains plug or switching o the
fuse.
Bulbs (especially halogen bulbs) become
very hot during operation. Even some time
after the appliance has been switched o,
there is still a risk of burns!
Before changing bulbs, isolate the extractor
hood from the power supply and leave the
bulbs to cool down!
Do not operate the extractor hood without
bulbs inserted.
Always switch on the extractor hood if a
hotplate is being used. If the extractor hood is
not switched on, condensation may form. As a
result, the appliance may corrode.
Do not place any
objects on the
extractor hood.
RISK OF FIRE
Do not ambé under the extractor hood or
work with a naked ame. When switched on,
the extractor hood draws ames into the lter.
There is a risk of re due to deposits on the
grease lter!
Do not leave pans, frying pans or deep-fat
fryers unattended if you are cooking food with
oils or fats, e.g. chips. Overheated oils or fats
can easily ignite!
A risk of re can be prevented by cleaning
the grease lters regularly and changing the
activated-carbon lter in good time.
Never operate the extractor hood without
grease lters.
Correct installation
Check the manufacturer’s specications for
the cooker to determine whether an extractor
hood can be operated over it.
If the manufacturer of the cooker has not
specied any signicant safety distances, the
following minimum distances apply
–550 mm between electric hob and the
lower edge of the extractor hood
–650 mm between gas hob (upper edge of
pan support) and the lower edge of the
extractor hood,
(see g. 1, page 2).
If various cookers are used, the greatest
indicated distance applies.
The width of the extractor hood must
correspond to the width of the cooking area.
The extractor hood must not be installed
over a solid fuel heating appliance which may
be a re risk (e.g. ying sparks) unless the
heating appliance has a closed, non-
detachable cover and the country-specic
regulations are observed. This restriction does
not apply to gas cookers and gas hobs.
To avoid damaging the hob, cover it when
installing the extractor hood.

page).
Appliance surfaces
NOTE: Observe the warranty regulations in the
enclosed service booklet.
The appliance surfaces and controls are
scratch-sensitive. Therefore observe the
following cleaning instructions:
– Avoid cleaning the extractor hood with dry
cloths, abrasive sponges, scouring agents,
cleaning agents containing sand, soda, acid,
chlorine or any other aggressive substances.
– Clean the appliance surfaces and controls
with a soft, damp cloth, washing-up liquid
or a mild window cleaner only.
– Do not scrape o dried dirt, but moisten with
a damp cloth.
– Clean carefully in the area of the controls to
avoid liquid from getting into the
electronics.
NOTE: Clean the stainless steel surfaces in the
direction of the ground surface only!
Do not use stainless steel cleaner for the
control buttons!
Metal-mesh grease lters
The metal-mesh grease lters absorb the
grease particles from the kitchen fumes.
The lter mats consist of re-proof metal.
RISK OF FIRE
As the lters become more saturated with
greasy residue, the ammability increases. The
function of the extractor hood may also be
impaired.
The risk of re is prevented by cleaning the
metal-mesh grease lters in good time.
When cleaning the grease lters, also
remove grease deposits from the accessible
parts of the housing with a damp cloth.
Cleaning the metal-mesh grease lters ...
Under normal operation (daily 1 to 2 hours),
the metal-mesh grease lters must be cleaned
1x month.
... in the dishwasher
The metal-mesh grease lters can be
cleaned in the dishwasher. Slight
discolouration may occur but this will not
aect the function of the grease lters.
The lters must be placed loosely in the
dishwasher. They must not be wedged in.
NOTE: Do not clean heavily saturated metal-
mesh grease lters together with utensils.
... by hand
When cleaning by hand, soak the grease
lters in a hot detergent solution, brush o the
dirt, rinse thoroughly and leave to dry.
Do not use any aggressive, acidic or alkaline
cleaning agents.
If dirt is particularly stubborn, we
recommend using a special grease solvent
spray. This can be ordered via the Online Shop.

11
Removing and installing the grease filters
Activated carbon lters bind the odours in
circulating-air mode.
Installing and removing the activated
carbon lters
1. Remove the grease lters (see Removing
and installing the metal-mesh grease lters).
2. Insert the activated carbon lter.
3. Lock the catch.
4. Reinsert the grease lters (see Removing
and installing the metal-mesh grease lters).
Changing the activated carbon lter

the activated carbon lters must be replaced
approximately 2x year.
The activated carbon lter is available from
specialist outlets, customer service or the
Online Shop (see Optional accessories). Use
original lters only.
Activated carbon lters do not contain any
pollutants. They can be disposed of in the
household refuse.
Before removing and installing the grease
lters, always follow the instructions and
warnings in the chapter entitled ”Safety
instructions”!

grease lters with your other hand.
(for appliances with edge extraction)
2. Clean the grease lters.
3. Reinsert the cleaned grease lters.

12
Changing the bulbs
Changing the halogen bulbs
Halogen bulbs become very hot during
operation. Even some time after the appliance
has been switched o, there is still a risk of
burns!
Before changing the halogen bulbs, ensure
that they have cooled down fully.
1. Press on the inner frame of the halogen
bulb.
2. Replace the defective bulb with a new one
of the same type and equivalent power (see
rating plate).
NOTE: When inserting halogen bulbs, do not
touch the glass tube. Therefore use a clean
cloth when inserting the bulb.
3. Close the inner frame of the halogen bulb.
NOTE: The inner frame of the halogen bulb
will not close unless it was fully opened
beforehand.
4. Restore the power supply by inserting the
mains plug or switching on the fuse.
NOTE: If the light does not function, check
whether the bulbs have been inserted cor-
rectly.
Before changing the bulbs, always follow
the instructions and warnings in the chapter
entitled ”Safety instructions”!
NOTE: Observe the warranty regulations in the
enclosed service booklet.
Defective bulbs should be replaced
immediately to avoid overloading the
remaining bulbs.

13
Prior to installation, always follow the
instructions and warnings in the chapter
entitled ”Safety instructions”!
Exhaust-air mode
The exhaust air is conveyed upwards via a
ventilation shaft or directly through the outer
wall to the exterior.
NOTE: The exhaust air must not be conveyed
into a functioning smoke or exhaust gas ue or
into a shaft which is used to ventilate
installation rooms which contain heating
appliances.
Before conveying the exhaust air into a
non-functioning smoke or exhaust gas ue,
obtain the consent of the appropriate heating
engineer.
Discharge exhaust air in accordance with
the ocial and statutory regulations (e.g.
regional building laws).
If the exhaust air is conveyed through the
outer wall, a telescopic wall box should be
used.
To ensure optimum performance, the
extractor hood requires:
– a short, straight exhaust air pipe and
– the largest possible pipe diameter.
If pipe bends cannot be avoided, ensure
the largest possible radii.
NOTE: If long, rough exhaust air pipes, a lot of
pipe bends or pipe diameters less than
150 mm are used, the air capacity will be less
than optimum and there will be an increase in
noise.
Use only pipes or hoses made of non-
combustible material for installation of the
exhaust air duct.
The manufacturer of the extractor hoods is
not responsible for complaints which can be
attributed to planning and design of the
pipework.
Connecting pipes
The diameter of the exhaust air pipes
should not be less than 150 mm.
Round pipes:
We recommend an inner diameter of
150 mm, however at least 120 mm.
Flat ducts must have the same inner cross-
section as round pipes.
There should be no sharp bends.
Ø 150 mm approx. 177 cm2
Ø 120 mm approx. 113 cm2
If pipe diameters differ:
Use sealing strips.
Connection of 150 mm ø exhaust air pipe
(recommended size)
Attach exhaust air pipe
directly to the air-pipe
connector and seal
appropriately. If using an
aluminium pipe, smooth the
connection area beforehand.
Connection of 120 mm ø exhaust air pipe
Attach reducing
connector directly to the air-
pipe connector.
Attach exhaust air pipe to
the reducing connector.
Seal both joints
appropriately.
