OPERATION
Before using the appliance for the first time
Induction cooking zone operation principle
Electric oscillator powers a coil placed inside the appliance. This coil produces a magnetic
field, which induces eddy currents in the cookware. These eddy currents induced by the
magnetic field cause the cookware to heat up.
This requires the use of pots and pans whose base is ferromagnetic, in other words sus-
ceptible to magnetic fields.
Overall, induction technology is characterized by two advantages:
Certain sounds can be heard during normal use of the induction hob, which do not affect
its correct operation.
The noises that can be heard during the normal appliance operation are the result of the
cooling fan operation, cooking method, cookware dimensions, cookware material and the
heat setting. These noises are normal and do not indicate a fault.
•
•thoroughly clean your induction hob first. The induction hob should be treated with the
same care as a glass surface.
•
•switch on the ventilation in the room or open a window, as the appliance could emit an
unpleasant smell during first use.
•
•operate the appliance while observing all safety guidelines.
•
the heat is only emitted by the cookware and its use is maximised,
•
there is no thermal inertia, since the cooking starts immediately when the pot is placed
on the hob and ends once it is removed
•
•Low-frequency humming. This noise arises when the cookware is empty and stops
when water is poured or food is placed in the cookware.
•
•High-frequency whizz. This noise arises in cookware made of multiple layers of differ -
ent materials at maximum heat setting. The noise intensifies when using two or more
cooking zones at maximum heat setting. The noise will stop or reduce when heat
setting is reduced.
•
•Creaking noise. This noise arises in cookware made of multiple layers of different ma -
terials. The noise intensity depends on how the food is cooked.
•
•Buzzing. Buzzing can be heard when electronics cooling fan operates.
