OPERATION

Introduction to Induction Cooking

CAUTION

- People with a heart pace maker should consult with their doctor before using this unit.

How Induction Cooking Works

Induction cooking is a safe, advanced, efficient and economical cooking technology. It works by electromagnetic vibrations generating heat directly in the cookware, rather than indirectly through heating the glass surface. The glass becomes hot only because the pan eventually warms it up.

① Iron Pot

② Magnetic Circuit

③ Ceramic Glass Plate

4 Induction Coil

⑤ Induced Currents

Before Using your Induction Hob

• Read this guide, taking special note of the SAFETY INSTRUCTIONS chapter.
• Remove any protective film that may still be on your induction hob.

Cookware

Choosing the Right Cookware

NOTE

- When purchasing cookware for use on the induction hob, look for cookware identified by the manufacturer as "induction ready" or "induction capable", or that is marked by the manufacturer as specifically designed for induction cooking. - The base material of the cookware must be magnetic for the cooking elements to activate. Use a magnet to check if the cookware base material is suitable. If the magnet sticks to the bottom of the cookware, the cookware can be used for induction cooking.

• Cookware made from the following materials is not suitable: pure stainless steel, aluminium or copper without a magnetic base, glass, wood, porcelain, ceramic, and earthenware.
• Do not use cookware with jagged edges or a curved base.

- Make sure that the base of your cookware is smooth, sits flat against the glass, and is the same size as the cooking zone. Use cookware whose diameter is as large as the graphic of the zone selected. Using a pot slightly wider will ensure that energy will be used with maximum efficiency. If you use a pot smaller than the cooking zone, efficiency could be less than expected. Pot smaller than 120 mm could be

undetected by the hob. Always centre your cookware on the cooking zone.

• Always lift cookware directly off the Induction hob.

Detection of Small Articles

When an unsuitable size or non-magnetic cookware (e.g. aluminium), or some other small item (e.g. knife, fork, key) has been left on the hob, the hob automatically goes to standby after 1 minute.

MAINTENANCE

Care and Cleaning

Cleaning the Appliance

CAUTION

- A steam cleaner is not to be used.

Everyday Soiling on Glass (Fingerprints, Marks, Stains Left by Food or Non-sugary Spillovers on the Glass)

1 Switch the power to the hob off.
2 Apply a hob cleaner while the glass is still warm (but not hot!).
3 Rinse and wipe dry with a clean cloth or paper towel.

NOTE

• When the power to the hob is switched off, there will be no 'hot surface' indication but the cooking zone may still be hot! Take extreme care.
• Heavy-duty scourers, some nylon scourers and harsh/abrasive cleaning agents may scratch the glass. Always read the label to check if your cleaner or scourer is suitable.
• Never leave cleaning residue on the hob: the glass may become stained.

Boilovers, Melts, and Hot Sugary Spills on the Glass

Remove these immediately with a fish slice, palette knife or razor blade scraper suitable for hobs, but beware of hot cooking zone surfaces:

1 Switch the power to the hob off at the mechanical isolation switch.

2 Hold the blade or utensil at a 30° angle and slowly scrape the soiling or spill to a cool area of the hob. Using the blade incorrectly or improperly can scratch the hob's surface.
3 Clean the soiling or spill up with a dish cloth or paper towel.
4 Follow steps 2 to 3 for 'Everyday Soiling on Glass' above.

NOTE

• Remove stains left by melts and sugary food or spillovers as soon as possible. If left to cool on the glass, they may be difficult to remove or even permanently damage the glass surface.
• Cut hazard: when the safety cover of a cleaning blade is retracted, the blade in a scraper is razor-sharp. Use with extreme care and always store safely and out of reach of children.

Spillovers on the Control Panel

1 Switch the power to the hob off.
2 Soak up the spill.
3 Wipe the control panel area with a clean damp sponge or cloth.
4 Wipe the area completely dry with a paper towel.

NOTE

- The hob may beep and turn itself off, and the control panel may not function while there is liquid on them. Make sure that you wipe the

control panel area dry before turning the hob back on.
