ance or pass it on to a third party, include these operating instructions as
well as the installation instructions.
▪ The appliance corresponds to recognised technology standards and the rel-
evant safety regulations. Proper use of the appliance is, however, essential
to avoid damage and accidents. Please therefore follow the precautions
given in these operating instructions.
▪ The heated surface will remain hot for some time after it is switched off and
will only cool down slowly to room temperature. Leave a sufficient amount of
time before you carry out work such as cleaning the appliance.
Note on use
▪ Tests have shown that under normal circumstances there is no risk to car-
diac 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

1 Safety precautions
Caution: Risk of burns!
▪ Overheated fat and oil can easily catch fire. Never attempt to extinguish
burning oil or fat with water. Danger of explosion! Smother the flames with a
fire blanket. Keep doors and windows closed.
Caution: Risk of injury!
▪ Keep pets away from the device.
Caution: Risk to life!
▪ Packaging materials, e.g. plastic film and polystyrene, can be dangerous for
children. Danger of suffocation! Keep packaging material away from children.
How to avoid damaging the appliance
▪ In the case of thermal failure, switch the solid plate off and allow to cool
down completely. Do not put any dishes on it. Do not cool with cold water
under any circumstances.
▪ Do not climb onto the appliance.
▪ To avoid damaging the silicon grouting, do not put hot cookware on the
frame.
▪ Do not cut or prepare food on the surface or drop hard objects onto it. Do
not drag cookware across the surface.
▪ Make sure than no sugary foods or juices end up on the hot cooking zones.
This can damage the surface. If sugary foods or juices do end up on the
hot cooking zones, remove these immediately with a glass ceramic hob
scraper (while the hob is still hot).
▪ Do not leave the appliance unattended during operation.
▪ Pots with pure copper or aluminium bases should not be used for cooking
as they 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 pots and cookware across the glass ceramic causes scratches. You
can largely avoid these by lifting pots and cookware when putting them into
place.
9
Page 10
1 Safety precautions
▪ The hob is an item for daily use: signs of usage such as scratches or visible
material abrasion from pots or cookware are normal. Intensive use leads to
more distinctive signs of usage. In such cases, the appliance continues to
function perfectly and a complaint is not justified. Safety is always guaranteed.
▪ 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.

4.3 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 directly 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
▪ finely adjustable
▪ powerful
▪ energy-efficient
▪ safe.
Induction hobs can only be used with cookware with a complete/full
magnetic base.
4.4 Pan detection
Every cooking zone is equipped with pan detection. This recognises cookware
with a magnetisable base that is suitable for use with induction hobs.
▪ If the cookware is removed during operation or unsuitable cookware is
used,
– the selected power level flashes alternately with .
▪ If there is no cookware placed on the cooking zone during the pan detec-
tion time of 10minutes:
– The cooking zone switches off automatically.
– The display changes from to .
– The appliance switches off after 10seconds if no other cooking zone is
switched on.
16
Page 17
4 Your appliance
4.5 Cookware
Suitable cookware
Only cookware with a full magnetic base is suitable for use with the induction
hob.
This can be checked in the follow ways:
▪ A magnet sticks anywhere on the base of the cookware.
▪ On the hob, the power level set illuminates and does not alternate with
the power level.
Do not heat any unsuitable cookware using aids such as metal rings
and the like. This can damage the hob.
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
▪ Coated cookware when empty may never be heated at a higher power level
than .
– The coating may otherwise become overheated and damaged.
▪ For frying, do not use a higher power level than .
Never use PowerPlus with coated frying pans.
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 disturbance, it can help to change the cookware.

6.3 Temperature control
Temperature control keeps the set temperature of the pan bottom constant. Cooking conditions are kept constant without having to regulate the temperature further.
Example uses: Longer searing, searing several portions one after the
other (e.g. meat, omelettes), poaching dumplings, reducing sauces and
syrups
Selecting and starting temperature control
▸ Bring the cookware and the food to be cooked to the desired temperature.
▸ Press the button once until the symbol flashes.
– appears in the power level display. This number refers to the holding
temperature. The holding temperature can be raised with levels - or
lowered with levels - .
▪ The temperature control can be switched off at any time by pressing on
the slider.
The timing of when the temperature control is activated is very important
for subsequent optimal regulation. Certain points to note are:
– Temperature control may not be activated directly from PowerPlus.
– The desired cooking stage should be stable before activating temper-
ature control. Taking searing meat as an example: Heat oil in the pan.
Activate temperature control just before the meat is added.
– Cookware may be briefly removed from the cooking zone in order to,
for instance, add the next lot of mixture when preparing omelettes. The
cookware must then be placed exactly back on the cooking zone.

8 Care and maintenance
Preferably, do not clean the appliance until it is cold.
Burns hazard!
Clean the hob after every use in order to prevent food residues from burning
on. Cleaning dried-on and burnt-on dirt requires more effort.
If the appliance is not cleaned correctly, the appearance and surface could be
damaged.
Do not clean the glass ceramic surface with scouring cleaning agents,
all purpose scouring pads, steel wool, etc. This can damage the surface.
▸ For cleaning everyday dirt, just use a soft cloth or sponge with water and a
suitable cleaning agent. Please follow the manufacturer's advice with regard
to cleaning agents. We recommend using protective cleaning agents.
▸ Remove encrusted dirt, e.g. from milk that has boiled over, with a glass
ceramic hob scraper while the hob is still warm. Please follow the manufacturer's advice with regard to the scraper.
▸ Remove sugary foods, such as marmalade, which have boiled over with a
glass ceramic hob scraper while the hob is still warm. Otherwise, this could
damage the glass ceramic surface.
▸ Remove melted plastic with a glass ceramic hob scraper while the hob is
still warm. Otherwise, this could damage the glass ceramic surface.
▸ Remove limescale stains using a small amount of lime-dissolving solution,
e.g. vinegar or lemon juice, when the hob has cooled down. Then clean
again with a damp cloth.
