In order to give you more fl exibility, your induction
cooktop is equipped with more cooking zones than
the number of induction generators. Each of those
generators is assigned to power a specifi c cooking
zone (Figs. 1 & 2). One or two cooking zones are
assigned to each generator. To be able to give you
access to the highest power ratings, the generator
will focus its power onto only one cooking zone. If you
use more than one cooking zone at high power on the
same generator, the generator will need to share its
power to both cooking zones, thus lowering the power
level of one of the cooking zones.
When you are sharing power (cooking in both zones),
the last zone set will cook at the power setting you
selected. The other zone will experience a slight
decrease from its power setting if both zones are set
high enough.
Depending on the size of your cooktop, 2 or 3 sections
are available:
The 30” cooktop is equipped with 4 cooking zones •
within 2 sections.
The 36” cooktop is equipped with fi ve cooking zones
•
within 3 sections. Note that on the 36” cooktop the
left cooking zone has its own section and will not
share its power.
To get the highest power output from your cooking
zones, cook with only one cookware per heating
section. If you need to use most of your cooking
zones at once, start your cooking process on only one
cooking zone within the heating section and then add
your second cookware on the second cooking zone
when the fi rst one has already reached its cooking
temperature.
Remember to select the power setting last for the
cooking zone you want to maintain at full power or set
the altered power to where you want it.
The electronics generating the induction fi elds are
pretty much noiseless but they do produce heat
at high power level. A soft-sounding cooling fan
activates when the unit is running multiple cooking
zones at once or when a cooking zone is set at very
high power settings.
The buzzing sound you could hear from your cooktop
is not coming from the electronics but from the
cookware you are using. Here are some causes of
this noise:
Most induction-ready cookware are made of several •
layers of materials. An encapsulated steel layer is
usually used to harness the induction fi eld and
transform it into heat, which is then transferred to
the other materials by radiant energy. The induction
fi eld will cause the steel layer to vibrate against
the other materials in which it is encapsulated.
This is the most common cause of noise from the
induction process. This buzzing only happens at
the higher power level settings. Note that high
quality cookware manufacturers weld this steel
layer in place which lowers or cancel this noise.
Light weight cookware may also vibrate. •
We recommend using heavy weight quality
cookware.
Cookware with warped bottoms can vibrate on the •
ceramic glass surface at high power settings.
• The power output of your induction
cooktop is capable of warping an empty pan. Never
use the higher power settings on an empty pan.
Even the highest quality cookware is vulnerable to
warping.
Riveted handles on cookware can also cause •
buzzing sounds from the vibrations.
Solid cast iron and enamelware cookware should •
not emit any noise. Top quality cookware made of
several layers should also be relatively quiet.
