Use of Induction Hob
Notes:
– Each selection (by pressing one of the keys) is indicated by an
acoustic signal (beep).
– User interface initial calibration: this feature is for the
keyboard calibration, to adapt the sensibility of the keys to
the final mechanical, environmental and user conditions.
Any time the cooktop is connected to the electrical supply
or after a power failure (that generates a reset in the user
interface), the first time the Key-Lock

The first touch of the Key-Lock
must be done in certain
condition: do not use gloves, use a clear finger.
It is also important to consider that the calibration process
requires a low level of ambient light in the area of the touch
keys. If the environmental light conditions are excessive (e.g.
halogen hood light/s on), the user interface calibration is
suspended and the cooking zones displays show " F " and
" L" alternating - error message " FL") until the correct light
conditions will be recovered.
In this case the direct environmental light/s must be switched
off before calibrating the cooktop; then, after completing the
process, the light/s can be switched on again.
– The touch control is switched off automatically (and a
warning beep sounds every 10 seconds):
• if one or more keys are touched for more than 10 seconds;
• if an object is positioned on the touch control area;
• in the case of spillage of liquids on the control keys.

The ceramic cooktop is fitted with induction cooking zones.
These zones, shown by painted disks on the ceramic surface, are controlled by a touch control system.
Induction Cooking System
When your induction hob is switched on and a cooking zone has been selected, the electronic circuits
produce induced currents that instantaneously heat the bottom of the pan which then transfers this heat
to the food.
Cooking takes place with hardly any energy loss between the induction hob and the food.
Your induction hob operates only if a correct pan with the right features is placed on a cooking zone.
Please refer to "Cookware for Induction Cooking".
Cookware for Induction Cooking
The induction cooking system OPERATES ONLY if using correct cookware suitable for induction cooking.
The bottom of the pan has to be ferromagnetic to generate the electromagnetic field necessary for the
heating process (meaning a magnet has to stick to the bottom of the pan).
Pans made from the following materials are not suitable:
– glass, wood, porcelain, ceramic, stoneware;
– pure stainless steel, aluminium or copper without magnetic bottom.
To check if a pan is suitable or not:
– Test the bottom of the pan with a magnet: if the magnet sticks, the pan is suitable.
– If a magnet is not available pour a small amount of water inside the pan and place the pan on a cooking
zone. Switch on the cooking zone: if the set power level flashes on the cooking zone display, the pan is
not suitable (then after 1 minute, the power level automatically returns to " 0 ").
Important note: the cooking zones will not operate if the pan diameter is too small. To correctly use the
cooking zones follow the indications given in the following table.
Minimum Pan Diameter Recommended
Induction Cooking Zone
(referred to the bottom of the pan)
Front zone, Ø 145 mm
Rear zone, Ø 210 mm
80 mm
130 mm
Pay attention: The pan shall always be centred over the middle of the cooking zone. It is possible to use
oversized pans but its bottom shall not touch the other cooking zone.
Always use pans with thick, completely flat bottom.
Do not use pans with concave or convex bottom; these could cause overheating of the cooking zone.
Note: Some types of pans could cause noise when used on an induction cooking zone.
The noise does not mean any failure on the appliance and does not influence the cooking operation.

Cleaning and Maintenance
Cleaning the Ceramic Hob
Do not use a steam
cleaner because the
moisture can get into
the appliance thus
make it unsafe.
– Before you begin cleaning make sure that the hob is switched off.
– Remove spillages and other types of incrustations.
– Dust or food particles can be removed with a damp cloth.
– If you use a detergent, please make sure that it is not abrasive or scouring.
Abrasive or scouring powders can damage the glass surface of the hob.
– All traces of the cleaner must be removed with a damp cloth.
– Dust, fat and liquids from food that has boiled over must be removed as
soon as possible.
– If they are allowed to harden they become increasingly difficult to remove.
This is especially true in the case of sugar/syrup mixtures which
could permanently pit the surface of the hob if left to burn on it.
– If any of these products has melted on the ceramic surface, you should
remove it immediately (when the surface is still hot) by using a scraper to
avoid any permanent damage to the surface of the hob.
– Do not put articles on the hob which can melt: i.e plastic, aluminium foil,
sugar, sugar syrup mixtures etc.
– Avoid using a knife or other sharp utensil as these may damage the ceramic
surface.
– Do not use steel wool or an abrasive sponge which could scratch the surface
permanently.
Stainless Steel Elements (Side Stainless Steel Trims)
– Stainless steel parts must be rinsed with water and dried with a soft and
clean cloth.
