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. 1). 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.

To get the highest power output from your cooking zones, cook with only one ¢ookware per generator. If you need to use most of your cooking zones at once, start your cooking process on only one cooking zone within the generator 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.

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 cool<ware 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

heat, which is then transferred to the other materials by radiant energy. The induction field wiil 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.
