USE OF INDUCTION HOB

Before using the induction hob, read this manual carefully and take note on the “Safety Guidelines” section.
Remove any protective film that may still be on the induction hob.
Induction Cooking System
Induction cooking is a safe, advanced, efficient, and economical cooking technology.
When cooking zone is selected, the electromagnetic circuit produce induced currents that instantly heat the bottom of the cookware which then transfer heat directly to the food. Cooking takes place with hardly any energy loss between the induction hob and food. The glass becomes hot only when the cookware eventually heats it up. Induction hob operates only if a correct pan with right features and dimension is placed on the cooking zone – refer to cookware selection for induction cooking. Cookware for Induction Cooking

• Only use cookware with a base suitable for induction cooking. Look for the induction symbol “ ” on the packaging or at the bottom of the pan.

• Cookware made from the following materials is not suitable

• Pure stainless steel, aluminum or copper without a magnetic base, glass, wood, porcelain, ceramic, and earthenware.

• To check if the cookware is suitable for induction,

• Use a magnet. Put the magnet at the bottom of the base and if the magnet sticks, the cookware is suitable.

• If you do not have a magnet, put some water in the cookware you want to check and place on the cooking zone. Follow the steps under ‘To start cooking’. If the symbol “ ” does not appear on the display and the water is heating, the pan is suitable.

• The cooking zone will not operate if the cookware diameter is too small (the symbol “   ” will appear on the display. Follow the recommended cookware diameter given in the following table to correctly use the cooking zone.

Note: Some cookware available in the market is not in good quality or has an effective ferromagnetic area which is smaller than the diameter of the cookware itself. Avoid using this cookware as the induction cooktop may not function properly or it may cause damage to the cooktop.
Do not use cookware with jagged edges or a curved base.Make sure that the base of your pan is smooth, sits flat against the glass, and is the same size as the cooking zone. Always center your pan on the cooking zone.Always lift pans off the ceramic hob – do not slide, or they may scratch the glass.
Note: Some type of cookware may cause noise during cooking – the noise is normal and does not mean any malfunction of the appliance.
Some induction cookware doesn’t have a complete ferromagnetic base:
If the material of the bottom of the cookware contains aluminum, the ferromagnetic area will also be reduced. This may mean that the cookware will not become hot enough or even be detected. Touch Control
The hob is fitted with induction cooking zones. These zones, shown by the painted disks on ceramic surface, are controlled by touch control system
Notes:

• The control responds to touch, so you don’t need to apply any pressure.
• Use the ball of your finger, not the tip.
• You will hear an acoustic sound each time a touch is registered.
• Make sure the control area is always clean, dry and that there is no object (e.g. a utensil or a cloth) covering them. Even a thin film of water may make the control difficult to operate.
