SAFETY PRECAUTIONS

CHILD SAFETY

WARNING: • This appliance is not intended for use by young children or infirm persons

unless they have been adequately supervised by a responsible person to

ensure that they can use the appliance safely.

• Young children should be supervised to ensure that they do not play with

the appliance.

• Accessible parts may become hot during use. Young children should be

kept away.

SAFETY DURING USE

• This appliance may only be used for normal cooking and frying in the home. It is not

designed for commercial or industrial purposes.

• Do not use the cooktop to heat the room.

• Take care when plugging in electric appliances near the cooktop. Cords must not

come into contact with the hot surface. This could cause damage to the cooktop and cable

SAFETY PRECAUTIONS

• Utensil handles should be turned inward and should not extend over adjacent

cooking zones to reduce the risk of burns, ignition of flammable materials, and spillage

due to unintentional contact with the utensil.

• Never leave prepared food on the Cooking Zones. Boilovers cause smoking and greasy

spillovers that may ignite, or a pan that has boiled dry may melt or become damaged.

• Protective liners: Do not use aluminum foil to line any part of the cooktop. Only use

aluminum foil as recommended after the cooking process, if used as a cover to be placed

over the food. Any other use of aluminum foil may result in the risk of electric shock, fire or

short circuit.

• Glazed cooking utensils: Only certain types of glass, glass/ceramic, ceramic,

earthenware, or other glazed utensils are suitable for rangetop service without

breaking due to the sudden change in temperature. Check the manufacturer’s

recommendations for cooktop use.

• Ventilating hood: The ventilating hood above your cooking surface should be

cleaned frequently, so the grease from cooking vapors does not accumulate on the

hood or filter.

• Do not clean or operate a broken cooktop. If cooktop should break, cleaning solutions

and spillovers may penetrate the broken cooktop and create a risk of electric shock.

Contact a qualified technician immediately.

• Clean cooktop with caution. If a wet sponge or cloth is used to wipe spills on a hot

cooking area, be careful to avoid a steam burn. Some cleaners can produce harmful fumes

if applied to a hot surface.

SAFETY DURING USE ^(cont.)

• Do not place hot cookware on cold cooktop glass. This could cause glass to break.

• Do not slide pans across the cooktop surface. They may scratch the cooktop surface.

• Do not let pans boil dry. This may cause permanent damage in the form of breakage,

fusion, or marking that can affect the ceramic-glass cooktop. (This type of damage is not

covered by your warranty.)

• Never leave surface units unattended at high heat settings. Boilover causes smoking

and greasy spillovers that may ignite.

CAUTION: DO NOT pick up the supplied bridge pan handles after cooking. They might

be hot and there is a risk of burning yourself.

SAFETY WHEN CLEANING

• Always switch off the appliance before cleaning.

• For safety reasons, do not clean the appliance with a steam jet or high-pressure

cleaner.

• Clean the cooktop in accordance with the maintenance and cleaning instructions in

this manual.

SAFETY PRECAUTIONS

• Do not use harsh abrasive cleaners or rough metal scrapers to clean the cooktop

glass since they can scratch the surface, which may result in shattering of the glass.

COOK MEAT AND POULTRY THOROUGHLY

Cook meat and poultry thoroughly—meat to at least an INTERNAL temperature of 160°F and

poultry to at least an INTERNAL temperature of 180°F. Cooking to these temperatures

usually protects against foodborne illness.

HOW TO AVOID DAMAGE TO THE APPLIANCE

• Prior to using your cooktop for the first time, apply the recommended cooktop cleaning

creme to the ceramic surface. Buff with a non-abrasive cloth or pad. This will make cleaning

easier when soiled from cooking. The special cooktop cleaning cream leaves a protective

finish on the glass to help prevent scratches and abrasions.

• Do not use the cooktop as a work surface or storage space.

• Please be careful at the edges when moving pots and pans around.

• Do not have the cooking zones on with empty pans, or with no pots or pans on them.

• Ceramic glass is very tough, and impervious to sharp temperature changes but is not

unbreakable. It can be damaged if particularly hard or sharp objects fall onto it.

• Be very cautious if using pots made of cast iron, or other pots with rough edges or burrs.

Moving these can cause scratches on glass.

• If sugar or a mixture containing sugar falls onto a hot cooking zone and melts, remove

immediately, while still hot. If left to cool down, it may damage the surface when removed.

NOTE: There is a risk of burning yourself when the glass scraper is used on a hot

cooking zone!

• Keep meltable objects or materials away from the ceramic glass surface, for example,

plastic utensils, aluminum foil, or cooking wraps. If any materials or foodstuffs melt on the

ceramic-glass surface, these should be cleaned up immediately.

DISPOSAL OF OLD APPLIANCES

To protect the environment, it is important that worn-out appliances are disposed of in the

correct manner.

• The appliance must not be disposed of with household rubbish.

• You can obtain information about collection dates or public refuse disposal sites from your

local health council or environmental health office.

CAUTION: Before disposing of old appliances please make them inoperable so they

cannot be a source of danger. To do this, have a qualified person disconnect

the appliance from the house circuitry.

READ AND FOLLOW THIS SAFETY INFORMATION CAREFULLY.

INDUCTION

INDUCTION COOKING

HOW INDUCTION COOKING WORKS

An induction coil is beneath the ceramic glass cooking surface. This

generates magnetic fields, which act directly on the base of the pots and

pans as compared to methods that first heat the ceramic glass. This

means that the base of the pan is immediately heated up, saving time

and energy.

Since the heat required for cooking is generated directly in the base of the

pan, the Cooking Zone itself warms up only slightly. The cooktop becomes hot from the heat

from the base of the pan.

NOTE: If there is no pot or pan on the cooking zone, there is no energy transfer (heating up).

This prevents the Cooking Zones being switched on and becoming hot accidentally.

IMPORTANT:

• Remove all tape and packaging wrap before using the appliance. Destroy the carton and

plastic bags after unpacking the appliance. Never allow children to play with packaging

materials.

• Electromagnetic fields can affect electronic circuits and interfere with portable radios and

phones.

• Do not put magnetically active objects (e.g., credit cards, computer diskettes, cassettes) on or

near the ceramic glass surface while one or more induction cooking zones are in use!

• Do not put any metallic objects (e.g., spoons, pan lids) on the Cooking Zones as they can

become hot when the Cooking Zones are in use.

SELECTING COOKWARE

The magnetic Cooking Zone sensors located below the cooktop surface require the use of

cookware made with magnetic material in order to start the heating process on any of the

Cooking Zones. When purchasing pans, look for cookware specifically labeled by the

manufacturer for use with induction cooktops.

POTS AND PANS

• In principle, all pots and pans with magnetic bases are suitable. These include steel, steel-

enamel, as well as cast-iron pots and pans.

• High grade steel pans with a mixed metal base (sandwich base, e.g. Tefal ® with an

aluminum/copper base) are suitable for induction only if the manufacturer has expressly

marked them as such. In that case they have a magnetic material in the base.

• If you wish to use a special type of pan (e.g., a pressure cooker, simmering pan, wok), please

follow the manufacturer’s instructions and do not use a very thin pan.

NOTE: Some cookware can produce noises when used on induction cooking zones. This is not

a fault in the cooktop, and its function will not be impaired in any way as a result.

SUITABILITY TEST:

If you are not sure if a pot or pan is suitable for use with your induction cooktop, you can find

out with a few simple tests:

INDUCTION

• Place a pot filled with a little water (1/8 1/4 ) on the Cooking Zone. Set the Cooking Zone to

full power (power level 9).

CAUTION: The pan base of suitable kitchenware heats up within a

few seconds! Water should boil rapidly.

• You can also check cookware suitability with a magnet. If the magnet

remains fixed to the base of the pan, the pan is suitable for induction

cooking.

SELECTING COOKWARE (continued)

AVOIDING SCRATCHES

It is recommended to always use heavier gauge stainless steel cookware on your induction

cooktop surface. This will help reduce the possibility of developing scratches on the ceramic

surface. Low-quality cookware can scratch the cooktop surface.

Cookware should always be lifted over the ceramic cooktop surface to prevent scratching.

Sliding any type of cookware over the ceramic cooktop can affect the overall appearance of the

cooktop. Over time, sliding ANY type of cookware over the ceramic cooktop may alter the

overall appearance of the cooktop. Eventually, the buildup of scratches can make cleaning the

surface difficult and degrade the overall appearance of the cooktop.

Scratches can also result from grains of sand (e.g., after washing vegetables) which are

dragged with the pot across the cooking surface.

USE FLAT-BOTTOMED COOKWARE

Cookware must fully contact the surface of the cooking element. Use flat-

bottomed pans sized to fit the cooking element and amount of food being

prepared. Check for flatness by rotating a ruler across the bottom of the

cookware.

FOR BEST RESULTS:

Always follow the recommendations for proper cookware type and size. In addition:

• Do not use dirty pans with grease buildup. Always use pans that are easy to clean after

cooking, and make sure that the bottoms of the pans are clean and dry.

• When cooking with large amounts of liquid, use large pots so that nothing can boil over.

• Do not let pans boil dry. This may cause permanent damage in the form of breakage, fusion,

or marring that can affect the ceramic cooktop. (This type of damage is not covered by your

warranty.)

• Match the pan size and Cooking Zone to the amount of food being prepared.

TIPS FOR SAVING ENERGY:

• Always position pots and pans before you switch on the

Cooking Zone.

• Dirty cooking zones and cookware use more electricity.

• Whenever possible, always have the lid firmly placed on

the pots and pans so that they are completely covered.

SELECTING COOKWARE

SELECTING THE PROPER PAN SIZE

Minimum pan size =

7¹⁄4 (180 mm)

Minimum pan size =

5 (125 mm)

• There are 4 Cooking Zones on the induction

cooktop. Each element requires a minimum pan

size to be used effectively. The inner ring of each

cooking zone is a guide to correctly match the

minimum pan size. The bottom of the pan must

fully cover the inner ring for proper cooking to

occur.

Minimum

pan size =

5³⁄⁴

(145 mm)

• The thicker outer ring at each Cooking Zone is

helpful to determine the pan MAXIMUM size.

After centering the cookware on the Cooking

Zone, make sure the cookware does not extend

more than 1/2 beyond the thicker line on the

Cooking Zone. The pan must make FULL

contact on the glass surface without the bottom

of the pan touching the metal cooktop trim.

Only use the supplied pan on

the bridge element.

If a pan made of the correct material is centered

properly on any of the active Cooking Zones but is

TOO SMALL, the affected Cooking Zone LED will

blink and the pan will not heat.

COOKWARE SELECTION AND PLACEMENT

It is important that the proper cookware be used and placed correctly on the cooktop. ANY one

of the incorrect conditions shown below may be detected by the sensors located below the

ceramic cooktop surface. If this happens, one or more of the Cooking Zones will not heat, and

an F will appear in the affected Cooking Zone display. Correct the problem before attempting to

CLEANING AND CARE

CLEANING THE COOKTOP

General cleaning for induction ceramic glass cooking surfaces is considerably easier than for

cooking surfaces with radiant heating.

NOTE: To prevent accidental activation of the controls, it is recommended that you set the

CHILD LOCK feature before cleaning.

IMPORTANT:

• Cleaning agents must not come in contact with the hot ceramic-glass surface. All cleaning

agents must be rinsed off thoroughly with clean water.

• Do not use any aggressive cleaners such as grill or oven sprays, coarse scouring cleansers,

or abrasive pan cleaners.

• Clean the ceramic-glass surface after each use when it is warm to the touch or cold. This will

prevent spills from becoming burnt on. Remove water marks, grease and discoloration with a

glass scraper and ceramic-glass cleaner.

NOTE: You can obtain glass scrapers and ceramic-glass cleaners from your local hardware

store.

GENERAL CLEANING

When it is cool, wipe the ceramic-glass surface with a damp cloth and a small amount of

ceramic glass cleaner.

Wipe dry with a clean cloth.

Once a week, thoroughly clean the entire ceramic-glass cooking surface with a commercially

available ceramic-glass cleaner.

Then, wipe the ceramic-glass surface using a clean, soft cloth dampened with clean water,

and polish dry with a clean lint-free cloth.

REMOVING HEAVY SOIL

To remove food that has boiled over or stubborn spills, use a

glass scraper.

Hold the glass scraper at an angle of about 45° to the

ceramic-glass surface.

Remove soiling by sliding the blade across the area.

Use a ceramic glass cleaner as described in GENERAL CLEANING.

PROBLEM SOILS

Remove sugar, melted plastic, aluminum foil, or other meltable materials with a glass scraper

immediately and while still hot. Failure to do so can cause permanent damage to the cooktop

surface. If the Cooking Zone has already cooled down, warm it up again.

IMPORTANT: There is a risk of burning yourself when the glass scraper is used on a hot

Cooking Zone. Use care and wear an oven mitt.

Then clean the cooktop normally when it has cooled down.

NOTE: Scratches or dark marks on the ceramic-glass surface

caused by a pan base with sharp edges cannot be removed.

However, they do not impair the function of the cooktop.

of the pan immediately without heating the ceramic-glass cooktop first. The two medium-sized

zones can be used together for larger oblong pans.

Touch Controls: Easy-to-use touch controls provide precise operation.

Easy Cleaning: The ceramic-glass cooking surface and touch control make for easy clean-up

and eliminate crevices and gaps where grease can accumulate.

Control and Function Displays: Digital displays show current settings and warn you of hot

surfaces from any residual heat of the corresponding cooking zone.

Safety Shutoff: All Cooking Zones feature a safety shut off that turns off the Cooking Zone if

ON/OFF is pressed but no power level is selected within 10 seconds.

OTHER FUNCTIONS

POWER SHARING

Your cooktop is equipped with four induction Cooking

Zones within two heating sections. The right and left

Cooking Zones are powered by two independent induction

inverters—one inverter for each of the two heating

sections. Two Cooking Zones in a heating section share

the power of one inverter. This is called power sharing.

For example, if you are cooking on both right Cooking

Zones, the last power level set will be maintained, while

the first Cooking Zone may experience a slight reduction

in the power level.

POWER SHARING TIPS:

Remember to set the power level for the food item you wish to keep constant last. When using

two Cooking Zones, you can maintain a constant power level for two pans on separate heating

sections. Place one pan on one of the Cooking Zones of the left heating section and the other

pan on one of the Cooking Zones of the right heating section.

AUTOMATIC SHUTOFF

If a Cooking Zone is in constant use for more than 17 hours and the control setting is not

changed, the Cooking Zone will shut off automatically.

AUTOMATIC POWER LEVEL CONTROL

The power level displayed may be different from the actual power level at the high temperature

range. To prevent the cooktop from overheating, the power level is controlled automatically.
