READ ALL INSTRUCTIONS BEFORE USE
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
insulation.
• Overheated fats and oils catch fire quickly.
You should supervise cooking when preparing
foods in fat or oil.
• After use, switch off the hob element by its
control and do not rely on the pan detector.
• Always keep the control panels clean and dry.
Do not let liquids or grease remain on the cooktop
controls area. Spilled or burnt-on foods can
activate or deactivate the appliance. Clean the
controls area thoroughly to resume normal
operation of the appliance.
• Never place combustible items on the
cooktop.
• Never keep any combustible items or aerosol
cans in a drawer located under the cooktop.
• Avoid placing metal cooking utensils on the
cooking surface areas. Metal objects can
become hot and cause burns.
• Know which touch keypad controls each
surface of the cooking zones.
• Clean the appliance regularly to keep all parts
free of grease that could catch fire. Exhaust fan
ventilation hoods and grease filters should be
kept clean. Do not allow grease to accumulate on
hood or filter. Greasy deposits in the fan could
catch fire. Refer to hood manufacturer's
instructions for cleaning.
• Use Proper Pan Sizes. This appliance is
equipped with one or more surface units of
different size. Select utensils having flat bottoms
large enough to cover the surface unit heating
element. The use of undersized utensils will
expose a portion of the heating element to direct
contact and may result in ignition of clothing.
Proper relationship of utensil to burner will also
improve efficiency.
• If pan is smaller than element, a portion of the
element will be exposed to direct contact and
could ignite clothing or potholder.
• Do not place any object on or near the control
keypad area in order to prevent accidental
activation of the cooktop controls.
• Utensil Handles Should Be Turned Inward and
Not Extend Over Adjacent Surface Units.
To reduce the risk of burns, ignition of flammable
materials, and spillage due to unintentional
contact with the utensil, the handle of a utensil
should be positioned so that it is turned inward,
and does not extend over adjacent surface units.
• 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. Do not use
sponges or cloth to wipe spills on a hot cooking
area. Use a proper metal scraper.

soda a dry chemical or foam-type extinguisher to
smother fire or flame.
• Always turn off all controls when cooking is
completed.
• Be sure you know which control pads operate
each surface unit.
Make sure you turned on the correct surface unit.
• Use only dry potholders.
Moist or damp pot holders on hot surfaces may
results in burns form steam.
Do not let the pot holder touch hot heating
elements. Do not use a towel or other bulky cloth.
• 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.
• Clean CookTop With Caution. Do not use
sponges or cloth to wipe spills on a hot cooking
area. Use a proper metal scraper.

HOW TO AVOID DAMAGE TO THE APPLIANCE
READ AND FOLLOW THIS SAFETY INFORMATION CAREFULLY.
SAVE THESE INSTRUCTIONS
• 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 worksurface or
storage space.
• Please be careful at the edges when moving pots
and pans.
• Do not operate the cooking zones with empty pots
or pans.
• Do not turn on the cooking zones with no pots or
pans on the element.
• Ceramic glass is very tough, and impervious to
sharp temperature changes but is not
unbreakable. It can be damaged if hard or sharp
objects fall on 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.
• Do not slide metal or glass across the cooktop
surface.
• 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 ceramicglass surface, these should be cleaned up
immediately.
NOTE: There is a risk of burning yourself when
the glass scraper is used on a hot cooking
zone!
• Do not use cookware with any dirt build up on the
bottom.
• Do not use cookware with rough or uneven
bottoms. This cookware can mark and scratch the
cooktop surface.
• Refer to the owners manual for proper cleaning
and maintenance of the cooktop.
• Do not use the glass cooktop surface as a
cutting board.
• Never cook directly on the galss. Always use
cookware.
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.
CAUTION
Burn Hazard: The Cooking Zones may appear
cool when turned ON and after they have been
turned OFF.

SELECTING COOKWARE
POTS AND PANS
The better the pot, the better the cooking results.
• You can recognize good pots and pans by their
bases. The base should be as thick and flat as
possible.
• Pots with aluminum or copper bases can cause
metallic discoloring on the ceramic glass surface
which is very difficult or impossible to remove.
• Be very careful when using cast iron pots or pots
with damaged bases which are rough and or have
burrs on them. Scratches can occur if they are
slid across the surface.
• When cold, pot bases are normally bowed slightly
in wards(concave). They should never be bowed
outwards(convex).
• 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.
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.
ENGLISH

SELECTING COOKWARE (cont.)
AVOIDING SCRATCHES
It is recommended to always use heavier gauge
stainless steel cookware on your ceramic 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.
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.
• Switch off the cooking zones before the end of the
cooking time to use the residual heat for keeping
food warm or for melting purpose.
• The base of the pot should have the same size as
the cooking zone.
• Using a pressure cooker shortens the cooking
times by up to 50%.
