Before using the induction hob, read this manual carefully and take note on the “Safety
Guidelines” section.
Remove any protective film that may still be on the induction hob.
Induction Cooking System
Inducon cooking is a safe, advanced, ecient, and economical cooking technology.
When cooking zone is selected, the electromagnec circuit produce induced currents
that instantly heat the boom of the cookware which then transfer heat directly to
the food. Cooking takes place with hardly any energy loss between the inducon hob
and food. The glass becomes hot only when the cookware eventually heats it up.
Inducon hob operates only if a correct pan with right features and dimension is placed
on the cooking zone – refer to cookware selecon for inducon cooking.
Cookware for Induction Cooking
•Only use cookware with a base suitable for inducon cooking.
Look for the inducon symbol “ ” on the packaging or at
the boom of the pan.
•Cookware made from the following materials is not suitable
•Pure stainless steel, aluminum or copper without a
magnec base, glass, wood, porcelain, ceramic, and
earthenware.
•To check if the cookware is suitable for inducon,
•Use a magnet. Put the magnet at the boom of the base and if the magnet
scks, the cookware is suitable.
•If you do not have a magnet, put some water in the cookware you want to check
and place on the cooking zone. Follow the steps under ‘To start cooking’. If the
symbol “ ” does not appear on the display and the water is heang, the pan is
suitable.
USE OF INDUCTION HOB
Iron pot
Magnetic circuit
Ceramic glass plate
Induction coil
Induced currents

•The cooking zone will not operate if the cookware diameter is too small (the
symbol “ ” will appear on the display. Follow the recommended cookware
diameter given in the following table to correctly use the cooking zone.
Cooking Zone (mm)
Minimum cookware diameter recommended
Ø 180
140 mm
Note: Some cookware available in the market is not in good quality or has an eecve
ferromagnec area which is smaller than the diameter of the cookware itself. Avoid using
this cookware as the inducon cooktop may not funcon properly or it may cause damage
to the cooktop.
Do not use cookware with jagged edges or a curved base.
Make sure that the base of your pan is smooth, sits at against the glass, and is the
same size as the cooking zone. Always center your pan on the cooking zone.
Always li pans o the ceramic hob – do not slide, or they may scratch the glass.
Note: Some type of cookware may cause noise during cooking – the noise is normal and does
not mean any malfuncon of the appliance.
Some inducon cookware doesn’t have a complete ferromagnec base:
⚫If the material of the boom of the cookware contains aluminum, the
ferromagnec area will also be reduced. This may mean that the cookware will
not become hot enough or even be detected.

Touch Control
The hob is fitted with induction cooking zones. These zones, shown by the painted
disks on ceramic surface, are controlled by touch control system
Notes:
•The control responds to touch, so you don’t need to apply any pressure.
•Use the ball of your nger, not the p.
•You will hear an acousc sound each me a touch is registered.
•Make sure the control area is always clean, dry and that there is no object (e.g. a
utensil or a cloth) covering them. Even a thin lm of water may make the control
dicult to operate.
TO START COOKING

for 1 second then goes o, indicang that the hob has entered the state of standby
mode.
1. Touch the ON/OFF control. All the indicators
show “- “
2. Place a suitable pan on the desired cooking zone (make sure the boom
of the pan and the surface of the cooking zone is clean and dry.)
3. Select the cooking zone by touching the relevant heang zone,
the indicator next to the selected zone will ash. The default power
level seng is 5.
4. Select a heat seng by touching the slider control (between minimum
“1” and maximum “9”) – slider your nger along the selector or touch at
one point to “jump” to a specic seng. You can modify the heat seng
at any me during cooking.

Note: Booster last for 5 minutes and the cooking zone is automacally set to the power level 9
at the end of the booster funcon

POWER MANAGEMENT
Power sharing funcon limits the maximum power used. The maximum available
power (preset) is shared between the cooking zones. If all zones are turned on, the
power management will not allow all zones to operate at full power but will alternate
the power among all zones so the total power will be equal to the preset maximum
power. The change will be visible on power level displays. The last command given to
a cooking zone takes priority on the power seng.
SAFETY KEY LOCK
This funcon locks the touch control key to prevent unintended use, for example, to
prevent children accidentally switch on the cooking zones.
When the safety key lock is acvated, all the controls except the ON/OFF key are
