Connecting the electricity supply cable to the mains
If the appliance is being connected directly to the
electricity mains an omnipolar switch must be installed
with a minimum opening of 3 mm between contacts.
!
The installer must ensure that the correct electrical
connection has been made and that it is fully compliant
with safety regulations.
Before connecting the appliance to the power supply,
make sure that:
• The appliance is earthed and the plug is compliant
with the law.
• The socket can withstand the maximum power of
the appliance, which is indicated on the data plate
located on the appliance itself.
• The voltage falls within the range of values indicated
on the data plate.
• The socket is compatible with the plug of the
appliance. If the socket is incompatible with the
plug, ask an authorised technician to replace it. Do
not use extension cords or multiple sockets.
!
Once the appliance has been installed, the power
supply cable and the electrical socket must be easily
accessible.
!
The cable must not be bent or compressed.
!
The cable must be checked regularly and replaced
by authorised technicians only.
!
The manufacturer declines any liability should
these safety measures not be observed.

Traditional cooking zones
Traditional cooking zones (A) consist of circular heating
elements. They turn red approximately ten seconds after they
have been switched on.
Each cooking zone is fitted with a control knob (D) which
allows you to select from 12 different temperature settings
between a minimum of 1 and a maximum of 12.
Extendable cooking zones*
The extendable radiant elements (B and F) are distinguished
by the fact that they have a double heating zone. You can
switch the smaller internal cooking zone on separately, or
both the external and internal zones together.
Circular extendable cooking zones*
The control knob (D) allows you to choose between two
power levels, which may both be adjusted between a
minimum value of 1 and a maximum of 12:
• The lowest power level can be set by turning the knob
clockwise from 1 to 12.
