GB

Start-up and use

!

 The glue applied on the gaskets leaves traces of grease on 

the glass. Before using the appliance, we recommend you 

remove these with a special non-abrasive cleaning product. 

During the first few hours of use there may be a smell of 

rubber which will disappear very quickly.

!

 A few seconds after the hob is connected to the electricity 

supply, a buzzer will sound. The hob may now be switched 

on.

!

 The software running the hob adjusts the maximum power 

absorbed by all cooking zones as necessary, so that the 

maximum total power output may be utilised in a flexible and 

independent manner. Two operating examples are illustrated 

in the pictures below.

In picture A, the front left-hand cooking zone is operating 

at maximum power (level 9) and, as a result, the rear left-

hand cooking zone cannot be set any higher than level 7; 

the corresponding Max indicator light is illuminated. As soon 

as the power of the front cooking zone has decreased, the 

corresponding Max indicator light will switch off and the rear 

cooking zone may be set to a higher power level.

Picture B illustrates a similar example, but with cooking zones 

positioned diagonally. If the front left-hand cooking zone is 

set to maximum (level 9), the rear right-hand cooking zone 

cannot be set any higher than level 4.

Information relating to the amount of energy consumed is 

provided by the indicator lights 

 which are illuminated 

when each corresponding plate has reached its maximum 

power output. When all the indicator lights corresponding to 

the active hotplates are illuminated, if you wish to increase 

the power level of one of the hotplates you will have to 

reduce the power level of another of the active hotplates first.

Types of noise during normal hob operation:

•  Buzz: due to the vibration of the metallic parts that make 

up the induction element and the pot; it is generated 

by the electromagnetic field required for heating 

and increases as the power of the induction element 

increases.

•  Soft whistle: heard when the pot placed on the heating 

zone is empty; the noise disappears once food or water is 

placed into the pot.

•  Crackle: produced by the vibration of materials on the 

bottom of the pot due to the flow of parasitic currents 

caused by electromagnetic fields (induction); can be more 

or less intense depending on the material making up the 

bottom of the pot, and decreases as the pot dimensions 

increase.

•  Loud whistle: heard when two induction elements of the 

same group function simultaneously at maximum power 

and/or when the booster function is set on the larger 

element while the other is auto-adjusted. Noise is reduced 

by decreasing the power level of the auto-adjusted 

induction element; pot bottom layers made of different 

kinds of materials are among the main causes of this 

noise.

•  Fan noise: a fan is necessary to ensure the hob functions 

correctly and to safeguard the electronic unit from 

possible overheating. The fan functions at maximum 

power when the large induction element is at maximum 

power or when the booster function is on; in all other 

cases, it works at average power depending on the 

temperature detected. Furthermore, the fan may continue 

to work even after switching the hob off, if the temperature 

detected is high.

The types of noise listed above are due to induction 

technology and are not necessarily operational faults.

Practical advice on using the appliance

!

 Use cookware made from materials which are compatible 

with the induction principle (ferromagnetic material). We 

especially recommend pans made from: cast iron, coated 

steel or special stainless steel adapted for induction. Use a 

magnet to test the compatibility of the cookware.

Ceramic, non magnetic Stainless steel

In addition, to obtain the best results from your hob:

•  Use pans with a thick, flat base in order to fully utilise the 

cooking zone.

•  Always use pans with a diameter which is large enough 

to cover the hotplate fully, in order to use all the available 

heat.

•  Make sure that the base of the cookware is always clean 

and dry, in order to fully utilise and extend the life of both 

the cooking zones and the cookware.

•  Avoid using the same cookware which has been used 

on gas burners: the heat concentration on gas burners 

may distort the base of the pan, causing it not to adhere 

correctly.

Safety devices

Pan sensor

Each cooking zone is equipped with a pan sensor device. 

The hotplate only emits heat when a pan with suitable 

measurements for the cooking zone is placed on it. If the 

indicator light is flashing, it may indicate:

•  An incompatible pan

•  A pan whose diameter is too small

•  The pan has been removed from the hotplate.

Overheating protection

If the electronic elements overheat, the hob switches off 

automatically and 

F

 appears on the display, followed by 

a flashing number. When the temperature has reached a 

suitable level, this message disappears and the hob may be 

used again.

Residual heat indicators

Each cooking zone is equipped with a residual heat 

indicator. This indicator signals which cooking zones are still 

at a high temperature. If the power display shows 

, the 

cooking zone is still hot. It is possible, for example, to keep a 

dish warm or melt butter or chocolate. As the cooking zone 

cools, the power display will show 

. The display switches 

off when the cooking zone has cooled sufficiently.

Safety switch

The appliance has a safety switch which automatically 

switches the cooking zones off after they have been in 

operation for a certain amount of time at a particular power 

level. When the safety switch has been triggered, the display 

shows “0”.

For example: the right rear hotplate is set to 5 and will switch 

off after 5 hours of continuous operation, while the front left 

hotplate is set to 2 and will switch off after 8 hours.

Buzzer

This can also indicate several irregularities:

•  An object (a pan, cutlery, etc.) has been placed on the 

control panel for more than 10 seconds.

•  Something has been spilt on the control panel.

•  A button has been pressed for too long. All of the above 

situations may cause the buzzer to sound. Remove the 

cause of the malfunction to stop the buzzer. If the cause of 

the problem is not removed, the buzzer will keep sounding 

and the hob will switch off.
