WARNINGS WARNINGS
WARNINGS
This appliance must be installed by a qualified professional in accordance with the current
regulations in the country where the appliance is installed and must only be used in a well
ventilated area. Ensure that your hob is correctly installed and grounded by a qualified
technician.
All our products have been designed in accordance with current safety standards. Read the
manuals before installing and using this appliance.
Disposal of the packaging
Unpack the hob completely before using.
After unpacking, dispose of the cardboard and plastic packaging as ecologically as possible.
Recycling packaging materials saves raw materials and reduces the amount of waste.
Do not let children play with the packaging.
The European Parliament’s 2012/19/EU directive on waste from electrical and electronic
equipment (WEEE) requires that used household appliances are not disposed of in unsorted
municipal landfills and must be collected separately to optimise recovery and recycling of the
materials they contain and thus reduce their impact on human health and the environment.
Consumers should contact their local authorities or their dealer with regard to the procedure to
be followed for the collection of their old appliance.
Please comply with local regulations for disposal of the packaging material. The packaging can
thus be recycled.
This “crossed-out bin” logo found on all products means that the equipment cannot
be disposed of with other waste, that it is the object of a selective collection with a
view to recovery, reuse or recycling.
Correct instal lation
Read the information in this manual carefully before turning on your cooktop. You will find
important information about your safety, the use, care and maintenance of your product, so that
you can enjoy it for a long time.
If your appliance stops working, read "What do to in case of a problem" first. You an often solve
minor problems yourself and avoid the cost of unnecessary service.
Keep this manual in a safe place. Pass it on to any new owners, for their safety and information.
Do not install cupboards or shelves directly above the hob. If you use the space above the hob,
only store rarely used items that can be safely stored in a location exposed to heat from the hob.

WARNINGS WARNINGS
Use of cooktop:
Warning
The accessible parts may be hot: keep young children at a safe distance.
Do not leave children alone and unsupervised.
The cooktop is not intended for use with an external timer or a separate remote control system.
Intensive or prolonged use of the appliance may require additional ventilation, for example, by
opening a window or, for more efficient ventilation, by turning up the power of the mechanical
ventilation, if installed.
A slight odour due to newness may be given off when the appliance is used for the first time. The
odour will fade quickly during use.
The induction hob responds very quickly to high power levels ("Booster" position): do not
leave the appliance unattended!
Use appropriately sized pans.
This hob has cooking surfaces of different sizes. Use flat-bottomed pans. Do not use unstable
saucepans, and turn handles inwards.
Do not use pans that are wider than the edge of the work surface.
Never place hot pans on the displays!
During cooking, beware of a very rapid increase in temperature on the cooking surfaces. Avoid
heating empty pans (risk of the pans overheating!)
Never place empty saucepans or frying pans on a cooking surface that is on.
Warning, when using a bain-marie pan: bain-marie pans can boil dry with no warning! This
damages the pan and the cooking surface. If this happens, the manufacturer shall not be held
responsible.
Never leave a deep fryer pan unattended. Always watch oil and heat it slowly. Deep fryer pans
must only be filled to one-third of their capacity. A deep fryer pan that is too full can spill over
when food is added. If you are using a mixture of oil and fat for frying, mix them together before
heating or as the fat melts.
Food that will be fried must be as dry as possible. Ice crystals on frozen food or moisture on cold
food can lead to boiling and oil spilling over.
Be very careful when heating fat and oil because these items can ignite if overheated. If possible,
use a deep-frying thermometer to prevent heating the oil beyond its smoking point.
Meals or dishes that contain oil must not be left unattended while cooking.
Never attempt to extinguish burning oil or fat with water! Put the lid on and turn the cooking
surface off.

THE PRINCIPLE OF INDUCTIONUSE
1. THE PRINCIPLE OF INDUCTION
The induction hob is made of ceramic glass, a material that keeps its shape when heated and is
easy to clean by wiping with a sponge.
Your induction hob is made up of 4 induction cooking surfaces and operates essentially due to the
magnetic properties of most pans used on ordinary cooktops.
Using the control knobs on the front of the hob, you control the electrical supply, which creates a
magnetic field. This field induces currents in the base of the pan placed on the hob.
These currents, called "induction currents", instantly heat the pan which then transfers the heat
to the food it contains.
The heat is produced directly inside the pan. Therefore, cooking takes place with practically no
energy loss between the induction hob and the food. The appliance's heating power is used to its
fullest capacity.
By removing the pan from the cooktop or simply turning the appliance off using the control
knobs, you instantly stop cooking.
Cooking is controlled entirely by an electronic circuit that provides outstanding flexibility and
unrivalled precise control settings.
The power and efficiency of an induction hob are far superior to those of a gas burner or electric
plate.
Advantages of an induction hob:
cooking uses very little energy, thanks to the direct transfer of energy to the pan,
improved safety, as energy is only transferred when the pan is placed on the cooking surface,
highly efficient energy transfer between the induction cooking surface and the bottom of the
saucepan,
very fast rise in temperature,
lower risk of burns because the cooktop only heats up when in contact with the pan. Spilled food
will not burn,
fast and very precise energy supply adjustment.
2. UTENSILS FOR THE INDUCTION COOKTOP
THE BEST PANS TO USE:
An induction plate essentially functions with pans containing magnetic materials:
- ENAMELLED STEEL PANS WITH OR WITHOUT A NON-STICK COATING. Casserole
dishes, deep fryer pans, frying pans, meat grills, etc.
- CAST-IRON PANS
USE

12 Induction Hob LA CORNUE W.
08NOTICEW/GB - 1
USEPANS
To avoid scratching the glass surface of your hob, choose a pan with an enamelled base, or avoid
sliding the pan over the surface of the hob.
- STAINLESS STEEL PANS SUITABLE FOR INDUCTION
Most stainless steel pans are suitable for induction cooking (saucepans, stockpots, frying pans,
deep fryer pans).
- ALUMINIUM PANS WITH SPECIAL BASES
NOTE: EVEN IF THE BASE OF THE PAN IS NOT PERFECTLY FLAT, IT MAY STILL BE
SUITABLE, AS LONG AS THE BASE IS NOT TOO DEFORMED.
When you use a pan with the "induction class" logo, you can be sure that it is perfectly compatible
with your hob under normal conditions of use.
UNSUITABLE MATERIALS:
Pans made of glass, ceramic or earthenware, made of aluminium and without a special base, or
made of copper and certain non-magnetic types of stainless steels.
TO USE PANS CORRECTLY:
- You will obtain the best results if you use a pan with a diameter similar to the size of the burner
outlined on the glass top.
- The pan must always be centred on the cooking surface.
To determine if a pan is suitable:
Check that the pan has the "induction compatible" marking and perform the test described below.
Magnet test:
Bring the magnet close to the base of the pan. If the pan attracts the magnet, then it will work on
the induction hob.
The quality and the materials of your pans are very important.
In our Showrooms, we have brought together professional, high-quality tools suitable for use in the
home.
We recommend Mauviel, Meyer or De Buyer products.
Note: "Induction" pans sold by some manufacturers may emit noises while being used. These
noises are due to the design of the pans.
Warning when using a bain-marie saucepan: bain-marie pans can boil dry without warning! This
damages the pan and the cooking surface. If this happens, the manufacturer shall not be held
responsible.
3. PAN DETECTOR
Energy is not transmitted when:
there is no pan on the cooking surface
the pan placed on the cooking surface is too small
the pan placed on the cooking surface is not suitable for induction (see table on page 13) even if
the cooking surface is turned on.

13
Induction Hob LA CORNUE W.
08NOTICEW/GB - 1
USE OPERATING TIMES
In this case, the display for the zone in question indicates that the cooking utensil is not suitable:
the number corresponding to the power level and the line underneath will flash (for example,
when power level 4 is selected):
When a suitable saucepan is placed on the cooking surface, the flashing stops. Power supply is cut
off when the cooking pan is removed; at that time the display will flash, as shown above, to
indicate that there is no pan.
If the pan placed on the cooking surface is small, but large enough to trigger the pan detector, the
cooking surface will only deliver enough power for the diameter detected.
Pan detector minimums:
4. MAXIMUM OPERATING TIMES
The induction cooktop features an automatic maximum operating time.
The continuous operation of each of the cooking surfaces depends on the cooking level selected
(see the table below).

OVERHEATING USE
Note: only applicable if the cooking surface settings are not changed during the operating time.
For safety reasons, after a certain amount of operating time, the cooking surface is turned off. The
maximum operating time depends on the power level selected. The table on page 13 sets out these
maximum operating times.
5. PROTECTION IN CASE OF OVERHEATING
When the cooktop is used continuously at full power and if the room temperature is high, the
electronics may not cool down sufficiently.
To avoid excessively high temperatures in the electronics system, the cooking surface power level
goes down automatically, when necessary.
For example, if the power level has been set to "9" but the induction generator is too hot, and
therefore is only able to deliver power at a level of "4", the display will indicate:
If the problem persists, lack of or insufficient ventilation could be the cause. See the "Ventilation"
chapter on page 24.
6. ADVICE FOR SAVING ENERGY
Below are some useful tips about using induction cooktops and suitable cooking pans
economically and efficiently
Pressure cookers are particularly economical in terms of cooking time and energy savings,
thanks to their air-tight seal and that fact that steam is trapped inside the pan. Quick cooking
times preserve vitamins.
Always make sure that there is enough liquid in the pressure cooker. Otherwise both the pressure
cooker and the cooking surface could become damaged by overheating an empty pan.
Whenever possible, cover saucepans with the correct lid.
If possible, use a pan that is the right size for the amount of food to be cooked. A large pan with
a little bit of food requires a lot of energy.
7. POWER LEVELS
The heating power of the cooking surfaces can be set to several positions. The table below gives
examples of cooking at the different positions.

15
Induction Hob LA CORNUE W.
08NOTICEW/GB - 1
RESIDUAL HEATUSE
8. RESIDUAL HEAT INDICATOR
The cooktop features a residual heat indicator for each cooking surface. Once cooking stops, all
the lines for the relevant display will flash, as a warning of the residual heat:
WARNING!
When the residual heat indicators are lit, do not touch or place heat-sensitive objects on the
cooking surfaces.
Risk of burns and fire.
However, the residual heat can be used to melt chocolate or butter, as well as to keep plates warm.
The residual heat indicator will continue to flash even if the hob is turned off (control knob M0
set to OFF).
The residual heat indicator turns off automatically when the glass has cooled down. If no cooking
surfaces are being used at that time, the hob will turn completely off. You may hear a clicking
sound from the electronics system, which controls this automatic complete shut down. This is
normal.

OPERATIONTURNING THE HOB ON
1. TURNING THE HOB ON
To turn the hob on, turn the M0 knob (the first on the left) clockwise, until it
comes to a stop.
The first line of each display (A1 - A2 - A3 - A4) lights up and the hob will make
a beeping sound:
This indicates that the hob is ready to be used.
2. REGULATING THE POWER LEVEL OF A COOKING SURFACE
The induction cooking surfaces (I1 or I2 or I3 or I4) can be set to 9 power levels (from 1 to 9)
depending on the type of cooking needed (see the table on page 15).
The maximum power level, also called "BOOSTER", is indicated by the letter P.
Turn the control knob (M1 to M4) of the desired burner (I1 – I2 – I3 – I4) clockwise to obtain the
desired level on the display for the relevant burner.
The power levels are displayed from 1 to 9, with a while line beneath.
For example, if the level set is "7", the display will show:

"BOOSTER" FUNCTIONOPERATION
3. "BOOSTER" FUNCTION
To use the BOOSTER:
The BOOSTER maximum power level can be found after level 9, by turning the control knob
slightly, still in a clockwise direction.
The letter "P" will then light up on the display for the selected cooking surface:
The BOOSTER function operates for a limited time (to avoid spoiled food). This function stops
automatically after 5 minutes. Then, the power automatically reverts to level 9 and the hob will
make a beeping sound:
To turn the BOOSTER off:
The booster can be turned off manually:
By turning the control knob clockwise: by moving the control knob the same amount as for
turning the BOOSTER on.
By reducing the power level, i.e. by turning the control knob anti-clockwise
4. TURNING A COOKING SURFACE OFF
To turn the cooking surface off, simply turn the control knob to "0".
The display for that surface will cause the first line to flash slowly. This means that the surface is
ready to be used again.

18 Induction Hob LA CORNUE W.
08NOTICEW/GB - 1
OPERATION"BRIDGE" FUNCTION
IMPORTANT: All the control knobs must be in the "0" position before turning the hob
completely off.
Otherwise, the next time that the hob is turned on, a flashing error message like the one shown
below will appear on the display and the hob will make a beeping sound:
The hob cannot be used until the relevant control knob is turned back to "0", so that all the
displays are as shown below when the hob is turned on:
5. "BRIDGE" FUNCTION
The I3 and I4 cooking surfaces can be joined to make one cooking surface for large pots, such as
oval casseroles, pans for fish, etc.
This single cooking surface is operated using the M5 control knob (on the right) and the power
level displayed is the same on displays A3 and A4, with the addition of the letter "B". For example,
if the level selected is "5", the two A3 and A4 displays will show at the same time:
Adjusting the power level, using the BOOSTER and turning off the BRIDGE cooking zone are
all carried out in exactly the same way as for a normal cooking zone, as described above.
After using the BRIDGE cooking zone, it is imperative to return to the "0" position so that the I3
and I4 cooking zones can be used separately.
Unless the M5 control knob is in the "0" position, the M3 and M4 control knobs will not operate
their respective cooking surfaces.
