Type of hotplate
The cooktop equipped with rapidhotplate.
For technical specifications refer to
“Cooktop Specifications– Cooking point”
Essentially, the rapid hotplate differs from the conventional one because it offers :
)Greater power.
)More rapid reaching of desired temperature.
Glass-ceramic cooktop.
The glass-ceramic cooktop permits rapid vertical transmission of heat from the heating element
below the cooktop to the pots or pans placed on top of it.
Heat does not spread horizontally, thus at a distance of just a few centimetres from the cooking
zone, the glass remains ” cool” to the touch.
The cooking zones are controlled by a power switch with 7 different positions or by a continuous
regulator with 10positions,as shownin figure37
Never cook food directly on the electric hotplates;
always use suitable pots or containers
5
Off
0

The intensity of heating for each zone can be adjusted progressively from “0” (off) to “6” 0R “11”
(max).
When the cooktop is on the indicator light remains lit.
When the temperature of the cooking zone is above 70°C, the corresponding “residual heat”
indicator lamp lights up to warn that the zone is hot.
This lamp remains lit even after the cooking zone is switched off, to signal that the zone is still hot.
Residual heat persists for a relatively prolonged period of time after the cooking zone has been
switched off.
During this time, avoid touching the cooking zone and take precautions to ensure children
cannot touch it.
The indicator lamp switches off automatically once the temperature of the cooking zone falls below
70°C.
Safety tips for using the cooktop
)Before switching on, check which knob controls the desired cooking zone.
It is best to place the pot or pan on the cooking zone before switching on, and remove it only
after switching off.
)Use only flat bottomed pans with a regular surface (exercise caution with cast iron pans).
Irregular bottoms can scratch the glass-ceramic surface. Check the bottom is clean and dry
)Do not use the cooktop if the surface is broken or damaged.
)Bear in mind that the cooking zones remain hot for a relatively long time (about 30 min.) after
switching off.
)Do not allow heavy or sharp objects to fall on the glass-ceramic cooktop.
)
If you find a crack on the cooktop, disconnect the appliance from the mains electricity
immediately and contact the After-sales Service.
)Never cook food directly on the glass-ceramic cooktop; always use suitable pots or containers.
Types of cooking zones
“hi-light” radiant zone
The heating element comprises a tape heating coil which reaches working temperature extremely
quickly.
This zone is controlled by a continuous power regulator.
