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:

Buzz:

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:

Soft whistle:

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:

Crackle:

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:

Loud whistle:

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:

Fan 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.

If the

-----

button is pressed for an extended period

of time, the display scrolls quickly though the power levels
and timer minutes.

Switching on the hob

To switch the hob on, press and hold the

button for

approximately one second.

Switching on the cooking zones

Each cooking zone is controlled using a selector button

and a power adjustment device consisting of a

double

-----

and

button.

• To begin operating a cooking zone, press the

corresponding control button and set the desired power

level (between 0 and 9) using the buttons

-----

and

Switching off the cooking zones

To switch off a cooking zone, select it using the

corresponding selector button

and:

• Press the

-----

button: the power of the cooking zone will

progressively decrease until it is switched off.

Only available in certain models.
