~

Do not drop anything on the ceramic surface of the cooktop. Although the ceramic glass is shock and scratch resistant, it is not shock or scratch proof.

~

Do not use pots or pans with pronounced edges or ridges on the ceramic cooktop. These could scratch the cooktop permanently. See

"Selecting Cookware" for more information. Grains of salt and sand can also scratch. Make sure that the bases of any pots and pans are clean, free of any fat or oils and are dry.

~

Do not allow either solid or liquid sugar, pieces of plastic or aluminium foil to fall on the burners when they are hot. If these residues are allowed to cool on the ceramic surface pitting or even cracking could occur.

~

Any spills should be removed as quickly as possible to prevent them from burning on and becoming difficult to remove.

~

Do not use a steam cleaner to clean the appliance. Steam could penetrate electrical components and cause a short circuit.

~

Never place hot pots or pans over the display, as the underlying electronics may be damaged.

5

IMPORTANT SAFETY INSTRUCTIONS

Injury prevention

~

Do not touch the cooktop or the area surrounding it during or immediately after use. The cooktop may be hot even though it is dark in color. Areas near it may become hot enough to cause burns. Do not touch, or let clothing or other flammable materials touch the cooktop or areas near it until they have cooled.

Wait until the residual heat indicators go out.

~

CAUTION: Do not store toys or items of interest to children in cabinets above or behind the appliance.

Children climbing onto the cooktop to reach these items may be injured.

~

Children should not be left alone or unattended near the appliance when in use. They should never be allowed to sit or stand on any part of the appliance.

~

Protect your hands with insulated gloves or potholders when using the appliance. Use only dry, heat resistant potholders. Moist or damp potholders used on hot surfaces can result in steam burns. Do not let the potholder touch the hot heating element. Do not use towels or other bulky items near the appliance.

15

Use

Overheating protection

Each burner is equipped with a temperature limiter. This limiter turns off the heating elements in the burner before the ceramic surface becomes too hot. Once the ceramic surface has cooled to a safe temperature the heating elements will automatically turn back on.

The overheating protection may be activated by:

– turning on a burner without putting a pan on it.

– heating an empty pan.

– an uneven pan not sitting evenly on the burner.

– the pan not conducting heat properly.

If the heating elements cycle on and off, even at the highest setting, the overheating protection has been activated.

16

Selecting cookware

The cooking surface

Your ceramic cooktop is made of an extremely hard and durable material.

The surface is scratch resistant, not scratch proof. Avoid using cookware with ridged bottoms. Ridged pots with dirty or chipped enamel bottoms may scratch the cooktop if they are pulled across the ceramic surface.

Make sure the cooktop and pot bottoms are clean before cooking. Certain items, particularly sugar grains or crystallized liquids such as molasses or syrups are actually harder than ceramic and can scratch the surface if they are not cleaned off immediately. Small or light scratches will not affect the safety or performance of the cooktop however.

The burner rings are fused into the ceramic glass and are resistant to wear if properly maintained. Do not use abrasive cleaners or pads, as they may eventually wear off the rings.

Pots and pans

Special cookware is not required, but as is true with all types of cooking appliances, the better the cookware, the better the performance.

Following these tips will allow you to make the most of your ceramic cooktop.

– For the most even and energy efficient cooking, the diameter of the pots should match the diameter of the burners as closely as possible.

– Use cookware with thick, flat, smooth bottoms. Slightly concave bottoms will also work adequately. Pans with convex bottoms will not cook well.

17

Selecting cookware

– Using a lid while cooking will minimize the loss of heat and decrease the cooking time.

– Copper bottom and aluminum pans may leave a residue on the cooktop in the form of metallic lines. This is normal. These lines can be removed using a non-abrasive ceramic cooktop cleaner or a sheilded scraper blade.

Be sure to clean the cooktop after each use. Each time the residue is allowed to melt it becomes harder to remove and may mar the appearance of the cooktop.

Let the cooktop cool before cleaning.

– Cast iron, glass or stoneware should not be used because they have poor heat transfer and may scratch the surface.

18

Cleaning and Care

Do not use a steam cleaner to clean this appliance. Steam could penetrate electrical components and cause a short circuit. Pressurized steam could cause permanent damage to the surface and to components for which the manufacturer cannot accept responsibility.

Do not use any sharp pointed objects which could damage the seal between the ceramic surface, the surrounding frame and the countertop.

Never use abrasive or caustic (oven) cleaners, dishwasher detergent, scouring pads, steel wool or hard brushes. They will damage the surface.

The ceramic surface can be cleaned using a cleaner for ceramic surfaces. Follow the manufacturer’s instructions.

Make sure that no cleaner residue remains on the ceramic surface by carefully wiping the cooktop with a damp cloth. They may damage the cooktop or produce toxic fumes when heated.

Be sure that pot and pan bases are clean and dry.

After cleaning, dry the ceramic surface with a soft cloth to prevent a build up of limescale deposits.

Clean any spills immediately before they become difficult to remove.

Clean the appliance regularly, preferably after each use. Allow the appliance to cool before cleaning.

^ Wipe off any soiling using a damp cloth. Stubborn soiling is best removed with a shielded scraper blade.

^ Apply a ceramic cleaner using a soft cloth or paper towel. To remove any limescale deposits or metallic residue apply a ceramic cleaner using a soft cloth and a shielded scraper blade if necessary.

^ After cleaning wipe the ceramic surface with a damp cloth and dry.

A cleaner with a special additive to prevent water marks and smears on the ceramic surface may be used.

Any melted solids like sugar, plastic or

aluminum foil should be removed as soon as possible, while the burner is still warm. If they are allowed to harden the cooktop may become pitted.

19
