1.3 Restriction on user group
This appliance may be used by children aged
8 or over and by people who have reduced
physical, sensory or mental abilities or inad-
equate experience and/or knowledge,
provided that they are supervised or have
been instructed on how to use the appliance
safely and have understood the resulting
dangers.
Do not let children play with the appliance.
Children must not perform cleaning or user
maintenance unless they are at least 15 years
old and are being supervised.
Keep children under the age of 8 years away
from the appliance and power cable.
1.4 Safe use
WARNING‒Risk of suffocation!
Children may breathe in or swallow small
parts, causing them to suffocate.
▶Keep small parts away from children.
▶Do not let children play with small parts.
Children may put packaging material over
their heads or wrap themselves up in it and
suffocate.
▶Keep packaging material away from chil-
dren.
▶Do not let children play with packaging ma-
terial.
WARNING‒Risk of poisoning!
Risk of poisoning from flue gases being
drawn back in. Room-air-dependent heat-pro-
ducing 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 dis-
charge the exhaust gases into the open
through an exhaust gas system (e.g. a chim-
ney). With the extractor hood switched on, air
is extracted from the kitchen and the adjacent
rooms. Without an adequate supply of air, the
air pressure falls below atmospheric pressure.
Toxic gases from the flue or the extraction
shaft are sucked back into the living space.
▶Always ensure adequate fresh air in the
room if the appliance is being operated in
exhaust air mode at the same time as a
room-air-dependent heat-producing appli-
ance is being operated.
▶It is only possible to safely operate the ap-
pliance if the pressure in the room in which
the heating appliance is installed does not
drop more than 4Pa(0.04mbar) below at-
mospheric pressure. This can be achieved
whenever 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. An incoming/ex-
haust air wall box alone does not ensure
compliance with the limit.
▶In any case, consult your responsible chim-
ney sweep. They are able to assess the
house's entire ventilation setup and will
suggest the suitable ventilation measures
to you.
▶Unrestricted operation is possible if the ap-
pliance is operated exclusively in circulat-
ing-air mode.

3 Environmental protection and saving energy
3.1 Disposing of packaging
The packaging materials are environmentally compat-
ible and can be recycled.
▶Sort the individual components by type and dispose
of them separately.
3.2 Saving energy
If you follow these instructions, your appliance will use
less energy.
Select the cooking zone to match the size of your
pan. Centre the cookware on the hob.
Use cookware whose base diameter is the same dia-
meter as the hotplate.
Tip:Cookware manufacturers often give the upper
diameter of the saucepan. It is often larger than the
base diameter.
¡Unsuitable cookware or incompletely covered cook-
ing zones consume a lot of energy.
Cover saucepans with suitable lids.
¡Cooking without a lid consumes considerably more
energy.

Disposal en
7
Lift lids as infrequently as possible.
¡When you lift the lid, a lot of energy escapes.
Use a glass lid.
¡You can see into the pan through a glass lid
without having to lift it.
Use pots and pans with flat bases.
¡Uneven bases increase energy consumption.
Use cookware that is suitable for the quantity of food.
¡Large items of cookware containing little food need
more energy to heat up.
Cook with only a little water.
¡The more water that is contained in the cookware,
the more energy is required to heat it up.
Turn down to a lower power level early on. Use a suit-
able ongoing power level.
¡If you use an ongoing power level that is too high,
you will waste energy.
Adjust the fan speed to the amount of steam pro-
duced during cooking.
¡The lower the fan speed, the less energy is con-
sumed.
Only use the intensive mode as required.
If cooking produces large amounts of steam, select a
higher fan speed in good time.
¡The odours are distributed around the room less.
Switch the appliance off when you are not using it.
¡
Ensure that there is sufficient ventilation when cook-
ing.
¡The appliance works more efficiently and with fewer
operating noises.
Clean or replace the filters at regular intervals.
¡The effectiveness of the filter is retained.
Product Information according (EU) 66/2014 can be

4.1 Disposing of old appliance
Valuable raw materials can be reused by recycling.
▶Dispose of the appliance in an environmentally
friendly manner.
Information about current disposal methods are
available from your specialist dealer or local author-
ity.
This appliance is labelled in accord-
ance with European Directive
2012/19/EU concerning used elec-
trical and electronic appliances
(waste electrical and electronic equip-
ment - WEEE).
The guideline determines the frame-
work for the return and recycling of
used appliances as applicable
throughout the EU.
5 Induction cooking
5.1 Advantages of induction cooking
Induction cooking is fundamentally different from tradi-
tional cooking methods, since the heat builds up dir-
ectly in the cookware. This offers numerous advant-
ages:
¡Saves time when boiling and frying.
¡Saves energy.
¡Easier to care for and clean. Spilled food does not
burn on as quickly.
¡Controlling the heat supply and safety; the hob in-
creases or decreases the heat supply as soon as
the user changes the setting. The induction cooking
zone stops the heat supply if you remove the cook-
ware from the cooking zone without you having to
switch it off first.
5.2 Cookware
Only ferromagnetic cookware is suitable for induction
cooking.
For example:
¡Enamelled steel cookware
¡Cast iron cookware
¡Special induction-compatible cookware made from
stainless steel
You can find more information on which items of cook-
ware are suitable for induction cooking in
→"Cookware test", Page28.
In order to achieve a good cooking result, ensure that
the ferromagnetic area of the cookware base corres-
ponds to the size of the cooking zone. If the cookware
is not detected on a cooking zone, place it on a cook-
ing zone with a smaller diameter.

en Induction cooking
8
If you are using the FlexZone as a single cooking zone,
you can use larger cookware that is particularly suited
to this zone. You can find information on positioning
the cookware in
→"Flex Zone", Page16.
The base of many items of induction cookware is not
fully ferromagnetic: For large cookware with a smaller
ferromagnetic base, only the area that is ferromagnetic
heats up. As a result, the heat is not distributed evenly.
The temperature of the non-ferromagnetic area may
therefore be too low for cooking.
Cookware bases that contain aluminium reduce the fer-
romagnetic area. This may reduce the output and the
cookware will not be detected sufficiently or at all, and
will therefore not be heated sufficiently.
Unsuitable cookware
Never use flow plates or cookware made of the follow-
ing:
¡Thin-walled normal steel
¡Glass
¡Clay
¡Copper
¡Aluminium
Composition of the cookware base
The material(s) from which the base of the cookware is
made may affect the cooking result. Cookware made of
materials that distribute heat evenly in the pot, such as
saucepans with a stainless steel sandwich base, save
time and energy.
You should ideally use cookware with a flat base, as
uneven cookware bases impair the heat supply.
No cookware/cookware of an unsuitable size
If you do not place cookware on the selected cooking
zone or the cookware is made of an unsuitable mater-
ial or is not the right size for the cooking zone, the dis-
play for the cooking zone flashes. To switch off the dis-
play, place a suitable item of cookware on the cooking
zone. If you do not place a suitable item of cookware
on the cooking zone within 90seconds, it automatically
switches off.
Empty cookware or cookware with a thin base
Do not heat empty items of cookware and do not use
cookware with a thin base. The hob is equipped with
an internal safety system. However, empty cookware
may heat up so quickly that the "Automatic switch-off"
function does not respond in good time and an excess-
ive temperature is reached. As a result, the base of the
cookware may melt and damage the glass plate. In this
case, do not touch the cookware, and switch off the
cooking zone. If the cooking zone no longer works
after cooling down, contact the technical customer ser-
vice.
Cookware detection
Each cooking zone has a minimum limit for the cook-
ware detection and this depends on the ferromagnetic
diameter and the material of the base of the cookware.
Therefore, always use the cooking zone that best cor-
responds to the diameter of the pot base.
