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.
5

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, Fig. 1.
–650 mm between gas hob (upper edge of
pan support) and the lower edge of the
extractor hood, Fig. 1.
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.

grease lters and an activated carbon lter
and conveyed back into the kitchen.
An activated carbon lter must be installed to
bind odours in circulating-air mode (see
”Removing and installing the grease lters”).
The complete installation set as well as the
replacement lters are available from specialist
outlets, customer service or the Online Shop.
The accessory number can be found at the
end of the operating instructions.
The extractor hood can be used in exhaust
air and circulating air mode.
Exhaust-air mode
The air which is drawn in is cleaned by the
grease lters and conveyed to the exterior by a
pipe system.
