Setting Cooktop Controls

Power Sharing

In order to give you more flexibility, your induction cooktop is equipped with more cooking zones than the number of induction generators. Each of those generators is assigned to power a specific cooking zone (Fig. 25). 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 shore its power to both cooking zones, thus lowering the power level of one of the cooking zones.

When you are shoring 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 five cooking zones within 3 sections. Note that on the 36" cooktop the right 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 first 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.

Cooking Zones

Operational Noises

The electronics generating the induction fields are pretty much noiseless but they do produce heat at high power level. A soft-soundingcooling 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-readycookware are made of several layers of materials. An encapsulated steel layer is usually used to harness the induction field and transform it into hea h which is then transferred to the other materials by radiant energy. The induction field 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.
