.Depending on the type of countertop, a small, uneven gap may form between countertop and the cooktop. For this reason, there is a flexible seal all the wa around the cooktop.

Normal operating sounds for the appliance

Induction heating technology is based on the vibration resistance of certain met when subjected to highifrequency waves. In some circumstances, these vibration can create certain sounds, such as the following:

Low humming like a transformer

Quiet whistling

Crackling

High\pitched whistle

This occurs when cooking at a high power. The cause of this is the amount energy which is transmitted from the appliance to the cookware. This sound disappears or becomes quieter when the power is turned down.

This occurs when the cookware is empty. This sound disappears when water o food is added to the cookware.

This sound occurs when cookware is used which consists of layers of different materials. The noise is caused by vibrations in the joint faces between the diff layers. It may change depending on the amount and type of food being cooke

This noise occurs principally in cookware which consists of layers of different materials when it is used at the highest heat setting and on two elements ne each other. This whistling disappears or becomes quieter when the power is tu down.

Fan noise	The electronics require	a	controlled temperature in order to function reliably. The
	cooktop is therefore fitted with a fan which runs at various speeds according t
	temperature detected.	The	fan may also continue to run even after the cooktop
	been switched off if the		temperature	it detects is still	too high.
	The sounds described	are	a normal	part of induction	technology and do not in
	a defect.
