(Important safety
information
Impor t ant saf et y informat i on :Warning – Danger of suffocation!
Packaging material is dangerous to children.
Never allow children to play with packaging
material.
:Warning – Danger of death!
Risk of poisoning from flue gases that are
drawn back in.
Always ensure adequate fresh air in the room
if the appliance is being operated in exhaust
air mode at the same time as room air-
dependent heat-producing appliance is being
operated.
Room air-dependent heat-producing
appliances (e.g. gas, oil, wood or coal-
operated heaters, continuous flow heaters or
water heaters) obtain combustion air from the
room in which they are installed and discharge
the exhaust gases into the open air through an
exhaust gas system (e.g. a chimney).
In combination with an activated vapour
extractor hood, room air is extracted from the
kitchen and neighbouring rooms - a partial
vacuum is produced if not enough fresh air is
supplied. Toxic gases from the chimney or the
extraction shaft are sucked back into the living
space.
■Adequate incoming air must therefore
always be ensured.
■An incoming/exhaust air wall box alone will
not ensure compliance with the limit.
Safe operation is possible only when the
partial vacuum in the place where the heat-
producing appliance is installed does not
exceed 4Pa (0.04mbar). This can be
achieved when the air needed for combustion
is able to enter through openings that cannot
be sealed, for example in doors, windows,
incoming/exhaust air wall boxes or by other
technical means.
In any case, consult your responsible Master
Chimney Sweep. He is able to assess the
house's entire ventilation setup and will
suggest the suitable ventilation measures to
you.
Unrestricted operation is possible if the vapour
extractor hood is operated exclusively in the
circulating-air mode.
:Warning – Risk of fire!
■Grease deposits in the grease filter may
catch fire.
Clean the grease filter at least every
2 months.
Never operate the appliance without the
grease filter.
Risk of fire!
■Grease deposits in the grease filter may
catch fire. Never work with naked flames
close to the appliance (e.g. flambéing). Do
not install the appliance near a heat-
producing appliance for solid fuel (e.g.
wood or coal) unless a closed, non-
removable cover is available. There must
be no flying sparks.
Risk of fire!
■Hot oil and fat can ignite very quickly. Never
leave hot fat or oil unattended. Never use
water to put out burning oil or fat. Switch off
the hotplate. Extinguish flames carefully
using a lid, fire blanket or something similar.
Risk of fire!
■When gas burners are in operation without
any cookware placed on them, they can
build up a lot of heat. A ventilation
appliance installed above the cooker may
become damaged or catch fire. Only
operate the gas burners with cookware on
them.
Risk of fire!
■Operating several gas burners at the same
time gives rise to a great deal of heat. A
ventilation appliance installed above the
cooker may become damaged or catch fire.
Never operate two gas burners
simultaneously on the highest flame for
longer than 15 minutes. One large burner of
more than 5kW (wok) is equivalent to the
power of two gas burners.
:Warning – Risk of burns!
The accessible parts become very hot when in
operation. Never touch hot parts. Keep
children at a safe distance.

Environmental protection en

:Warning – Risk of injury!
■Components inside the appliance may have
sharp edges. Wear protective gloves.
Risk of injury!
■Items placed on the appliance may fall
down. Do not place any objects on the
appliance.
:Warning – Risk of electric shock!
■A defective appliance may cause electric
shock. Never switch on a defective
appliance. Unplug the appliance from the
mains or switch off the circuit breaker in the
fuse box. Contact the after-sales service.
Risk of electric shock!
■Incorrect repairs are dangerous. Repairs
may only be carried out and damaged
power cables replaced by one of our
trained after-sales technicians. If the
appliance is defective, unplug the appliance
from the mains or switch off the circuit
breaker in the fuse box. Contact the after-
sales service.
Risk of electric shock!
■Do not use any high-pressure cleaners or
steam cleaners, which can result in an
electric shock.
Causes of damage
Caution!
Risk of damage due to corrosion. Always
switch on the appliance while cooking to avoid
condensation. Condensate can produce
corrosion damage.
Always replace faulty bulbs to prevent the
remaining bulbs from overloading.
Risk of damage due to ingress of humidity into
the electronic circuitry. Never clean operator
controls with a wet cloth.
Surface damage due to incorrect cleaning.
Clean stainless steel surfaces in the direction
of the grain only. Do not use any stainless
steel cleaners for operator controls.
Surface damage due to strong or abrasive
cleaning agents. Never use strong and
abrasive cleaning agents.
Risk of damage from returning condensate.
Install the exhaust duct in such a way that it
falls away from the appliance slightly (1°
slope).
7Environmental protection
En v i r o n ment al pr ot ect i on Your new appliance is particularly energy-efficient.
Here you can find tips on how to save even more
energy when using the appliance, and how to dispose
of your appliance properly.
Saving energy
■During cooking, ensure that there is a sufficient
supply of air to enable the extractor hood to work
efficiently and with a low level of operating noise.
■Adjust the fan speed to the amount of steam
produced during cooking. Only use intensive mode
when required. The lower the fan speed, the less
energy is consumed.
■If cooking produces large amounts of steam, select
a higher fan speed in good time. If the cooking
steam has already spread around the kitchen, the
extractor hood will need to be operated for longer.
■Switch off the extractor hood if you no longer require
it.
■Switch off the lighting if you no longer require it.
■Clean and (if required) replace the filter at regular
intervals in order to increase the effectiveness of the
ventilation system and to prevent the risk of fire.
■Put the lid on to reduce cooking steam and
condensation.
Environmentally-friendly disposal
Dispose of packaging in an environmentally-friendly
manner.
This appliance is labelled in accordance with
European Directive 2012/19/EU concerning
used electrical and electronic appliances
(waste electrical and electronic equipment -
WEEE). The guideline determines the
framework for the return and recycling of used
appliances as applicable throughout the EU.

ÇOperating modes
Oper at i ng modes Exhaust air mode
Note: The air must not be discharged into a flue that is
used for exhausting fumes from appliances burning gas
or other fuels (not applicable to appliances that only
discharge the air back into the room).
■Before conveying the exhaust air into a non-
functioning smoke or exhaust gas flue, obtain the
consent of the heating engineer responsible.
■If the exhaust air is conveyed through the outer wall,
a telescopic wall box should be used.
Air recirculation
Note: To bind odours in air recirculation mode, you
must install an activated carbon filter. The different
options for operating the appliance in air recirculation
mode can be found in the brochure. Alternatively, ask
your dealer. The required accessories are available
from specialist retailers, from customer service or from
the Online Shop.
1Operating the appliance
Oper at i ng the appl i ance These instructions apply to several appliance variants.
It is possible that individual features are described
which do not apply to your appliance.
Note: Switch on the extractor hood when you start
cooking and switch it off again several minutes after you
have finished cooking. This is the most effective way of
removing the kitchen fumes.
Note: Fold the glass cover forwards. This increases the
extraction area.
Control panel
Setting the fan
Note: Always adjust the fan strength to meet current
conditions. If there is a large build-up of steam or
fumes, select a high fan setting.
Switching on
Set the slide control to position 1, 2or 3.
Switching off the appliance
Set the slide control to position 0.
Lighting
The lighting can be switched on and off independently
of the ventilation.
Set the slide control to position 1.
The air which is drawn in is cleaned
by the grease filters and conveyed to
the exterior by a pipe system.
The air which is drawn in is cleaned by
the grease filters and an activated
carbon filter, and is conveyed back into
the kitchen.
