cumstances there is no risk to cardiac
pacemaker users. If, as the user of a
cardiac pacemaker (or a hearing aid or
another type of implant), you would like
to be reassured that using the appli-
ance does not pose a risk, you are ad-
vised to consult a competent medical
authority.
▪ If the appliance is visibly damaged, do
not use it. Contact our Customer Ser-
vices.

fire. NEVER attempt to extinguish burn-
ing oil or fat with water. Danger of ex-
plosion! Smother the flames with a fire
blanket. Keep doors and windows
closed.
▪ The accessible surfaces of the hob can
get very hot when operated with pans in
place.
Caution: Risk of injury
▪ Keep pets away from the appliance.
▪ The appliance is designed for use by
adults who are familiar with the content
of these operating instructions. Children
may not always be aware of the danger
involved in using electrical appliances.
Ensure proper supervision and do not
allow children to play with the appliance
– there is a danger that children could
hurt themselves.
Caution: Risk to life
▪ Packaging material, e.g. plastic film and
polystyrene, can be dangerous for chil-
dren and animals. Danger of suffoca-
tion! Keep packaging material away
from children and animals.
How to avoid damaging the appliance
▪ In case of overheating, switch the hot-
plate off and allow it to cool down com-
pletely. Do not put any dishes on it. Un-
der no circumstances use cold water to
cool it down quickly.
▪ Do not climb on to the appliance.
▪ Do not put hot cookware on the hob
frame in order not to damage the silic-
one joints.
▪ Do not cut or prepare food on the sur-
face and avoid impact with hard ob-
jects. Do not drag cookware across the
surface.
▪ Take particular care that sugary foods
or juices do not get onto the hot cook-
ing zones as this can damage the sur-
face. If sugary foods or juices do get on
to the hot cooking zones clean away
immediately (while still hot) with a
scraper.
▪ Pots with pure copper or aluminium
bases should not be used for cooking
as they can leave behind traces that
can be difficult to clean. If the traces
are not removed immediately after
cooking with a suitable cleaning agent,
they can be permanently burned on and
therefore permanently ruin the visual
appearance of the appliance.
▪ Sliding pans and cookware across the
glass ceramic causes scratches. This
can be largely prevented by lifting pans
and cookware up and then placing
them down in position.
1 Safety precautions
7
▪ The hob is designed to be used – signs
of use, such as scratches or the wear
and tear from pans and cookware, are
normal. The more intensively it is used,
the greater the signs of use; however,
the appliance remains in perfect work-
ing order and therefore does not give a
right of complaint. Safety is guaranteed
at all times.
▪ There is no such thing as completely
scratch-proof glass; scratches can even
develop on sapphire glass, which is
used in watches. The glass ceramic
used is of the best quality available on
the market.
2 Using for the first time
The appliance must be installed and connected to the electricity supply in accord-
ance with the separate installation instructions. Have a qualified fitter/electrician
carry out the necessary work.
All traces of adhesive must be removed before the appliance is used for the first
time.
During the first few hours of use, a cooking zone can give off an unpleasant smell.
This is normal for brand new appliances. Ensure that the room is well ventilated.

3.4 How induction hobs function
Induction hobs work very differently from conventional hobs or hot plates. The induction
coils under the glass ceramic plate produce a rapidly changing magnetic field which dir-
ectly heats up the magnetic base of the cookware.
The glass ceramic plate is only warmed by the hot cookware. Removing the cookware
from the cooking zone immediately interrupts the supply of energy.
Induction hobs are:
▪ quick reacting ▪ energy-efficient
▪ finely adjustable ▪ safe
▪ powerful
Cookware with a full-surface or full magnetic base is required for cooking with an
induction hob.

3 Appliance description
3.5 ZoneFlex cooking
A maximum of two items of cookware can be operated on any one ZoneFlex cooking
zone. The hob detects cookware with a diameter of ø11cm or larger, shows its position
in the pan detection display and activates the corresponding slider. Pans with different
diameters can be placed freely on the ZoneFlex cooking zones one behind the other. For
pan detection, cookware must be positioned centrally on the cooking zone areas.
For even frying, cookware must be positioned centrally on the cooking zone areas.
The diameter of the base of the cookware should not be larger than the cooking
zone areas.
3.6 Pan detection
Each cooking zone area is equipped with pan detection. This detects suitable induction-
compatible cookware with a magnetic base. Adjacent to the digital display, pan detection
appears in dark red (1b, 2b, 3b). It indicates which cooking zone areas (1a, 2a, 3a) are
activated.
▪ If the cookware is removed during operation or
if unsuitable cookware is used,
– the power level selected flashes alternately
with in the digital display.
▪ If no suitable cookware is placed on the cook-
ing zone areas while pan detection is running
(20seconds),
– the cooking zone areas switch off.
– the digital display changes from to «0».
– the appliance switches off after 30seconds
if no other cooking zone areas are in use.

If cookware that is too small (≤ ø11cm) is placed on a cooking zone area, it will
not be detected and therefore cannot be heated. The slider remains switched off.
3.7 MemoryFunction
If the cookware is moved or lifted inside the ZoneFlex cooking zone, the settings are
saved and automatically applied to the new position. The new position is indicated in the
pan detection display, and the relevant settings in the digital display.

3.8 Cookware
Suitable cookware
Only cookware with a magnetic base (minimum ø11cm) is suitable for use with the in-
duction hob.
This can be checked in the following ways:
▪ A magnet sticks anywhere on the base of the cookware.
▪ Only the power level set illuminates on the hob.
Do not heat any unsuitable cookware using aids such as metal rings and the like.
This can damage the hob.

General notes on cookware
▸ As far as possible ensure that the dia-
meter of the base of the cookware is
the same size as the upper diameter
of the cookware.
11
4 Operating the appliance
▸ We advise against the use of cook-
ware with a pressed base as this type
of cookware does not work with all in-
duction hobs.
▸ Some induction hobs have the melt,
keep warm and simmer functions. We
recommend using cookware without a
concave base for these functions.
▸ Handles that are loose or hollow can produce a loud whistling noise.
▸ The adherence of the cookware to the hob surface is reduced during operation, and
the cookware can therefore be moved more easily.
▸ Thick pan walls absorb the vibrations and reduce the noise level.
Energy-efficient cooking
For maximum energy efficiency and even heat distribution note the following:
▪ The base of the cookware must be clean, dry and smooth.
▪ Centre the cookware in the middle of the cooking zone.
▪ Use a well-fitting lid.
▪ Match the diameter of the cookware to the quantity of food to be cooked.
Coated cookware
▪ For frying, do not use a higher power level than «7».
▪ Coated cookware may be operated above level «7» provided that the bottom of the
pan is completely covered with liquid.
– The coating may otherwise become overheated and damaged.
Never use coated frying pans with automatic boost or PowerPlus.
Noise during cooking
Cookware can make noise during cooking. This does not indicate any malfunction, nor
does it affect the functioning of the appliance in any way.
Noise depends on the cookware used. If the noise causes considerable disturb-
ance, it can help to change the cookware.

7 Care and maintenance
Ideally, clean the appliance when it has completely cooled down.
Burns hazard!
Always clean the hob after use. This prevents food residue from burning on. Dried-on or
burned-on food residue is harder to clean off.
Use of improper cleaning techniques can result in damage to the markings or surface.
Avoid cleaning the surface of the glass ceramic hob with abrasive cleaning agents,
scouring pads, wire wool, etc. as they can damage the surface.
▸ Use only a soft cloth or sponge with water and standard washing-up liquid for clean-
ing everyday soiling.
▸ Remove stubborn soiling, e.g. boiled-over milk, while still warm using a glass ceramic
hob scraper. Always follow the scraper manufacturer's instructions for use.
▸ Foods with a high sugar content, e.g. marmalade, that boil over should be removed
while still hot using a glass ceramic hob scraper. The surface of the glass ceramic
hob could otherwise become damaged.
▸ Remove melted plastic while still warm using a glass ceramic hob scraper. The sur-
face of the glass ceramic hob could otherwise become damaged.
▸ Remove limescale stains when cool with a small amount of mild vinegar cleaner or
lemon juice. Then wipe clean with a damp cloth.
▸ Use a suitable Cleaning agent (see page 23) to remove stubborn soiling.
Cleaning
For good results, follow these cleaning instructions.
▸ To clean thoroughly, remove most of the soiling using a hob scraper or a special
cleaning sponge for glass ceramic hobs.

8 Trouble-shooting
▸ Add a few drops of a suitable Cleaning agent (see page 23) to the cold hob surface
and rub over the surface using kitchen towel or a clean cloth.
▸ Wipe off with a wet cloth and then polish with a dry cloth or the soft side of a suitable
cleaning sponge.
7.1 Cleaning agent
Glass ceramic with OptiGlass
Unsuitable cleaning agents may attack and damage the coating.
▸ Only use the cleaning agents and methods for glass ceramic
with OptiGlass that we recommend.
