3 DESCRIPTION OF THE DEVICE
The appliance is an induction hob with integrated worktop
extraction. The induction hob has 4 cooking zones with an
integrated extractor at the centre of the hob that ensures the
removal of cooking vapours.
The hob and extractor can be operated separately. You will
find an explanation of the operation of the device further in this
manual.
3.1 Principle of induction
There is an induction coil under each cooking zone. When this
is on, it produces a variable electromagnetic field that produces
an induction current in the bottom of the cooking pan. This
results in the warming up of the cooking pan on the cooking
zone.
Of course, suitable cooking pans are required for this:
–
Recommended cooking pans include those with a magnetic
base (you can check this using a magnet): a cast iron kettle,
black iron pan, enamelled metal cooking pans, stainless steel
pans with magnetic base, etc.
–
Unsuitable cooking pans include copper, stainless steel,
aluminium, glass, wood, ceramics, pottery, stainless steel
without magnetic base, etc.
The induction cooking zone immediately takes the size of the
cooking pan into account. If the diameter is too small, the
cooking pan will not work. The diameter varies as a function
of the diameter of the cooking zone. Should the cooking pan
not be adjusted to the hob, the symbol will continue to flash.

3.3 Noise caused by induction
When using an induction hob, all kinds of noises may occur.
These noises are dependent on the construction and the
materials of the bottom of the cooking utensils.
Humming
This occurs when cooking at a higher power and this is caused
by the amount of energy that is transferred from the hob to the
cooking utensils. The noise disappears or becomes weaker
when you set the hob to a lower position.
Sputtering
This noise occurs when the utensils consist of layers of different
materials. The noise is caused by vibrations in the areas where
the different material layers touch each other.
Whistling
Such noises generally arise when cooking with utensils
consisting of layers of different materials and when two adjacent
cooking zones are used simultaneously at maximum power.
The whistling noise disappears or becomes weaker when you
set the hob to a lower position.
Clicking
At lower power positions clicking noises may occur at electronic
switches.
Buzzing
A buzzing sound may occur when the fan is switched on. This
fan cools the electronics at intensive use of the hob. When the
temperature is too high, the fan will keep running after the hob
has been switched off.
