OPERATION
BEFORE USING THE COOKTOP
Read all instructions before using.
• Do not cook on a broken cooktop. If the cooktop is broken, cleaning
solutions and spillovers may penetrate the broken cooktop and create a
risk of electric shock. Contact a qualified technician immediately.
• Do not place hot cookware over the keypads or indicator lights on the
control panel. Placing hot cookware on the control panel can damage
the electronic underneath.
• Do not place or store items that can melt or catch fire on the glass
cooktop, even when it is not being used.
• Never leave surface units unattended at high heat settings. Boilovers
cause smoking and greasy spills that may catch on fire.
• Keep flammable items away from the cooktop.
• Turn off all controls when done cooking.
• Turn cookware handles 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 cookware.
• Always place the pan in the center of the surface unit you are cooking
on. Proper contact of cookware to heating element also will improve
efficiency.
• Clean cooktop with caution. If a wet sponge or cloth is used to wipe
spills on a hot cooking area, be careful to avoid steam burn. Some
cleaners can produce noxious fumes if applied to a hot surface.
WARNING
33
• Never cook directly on the glass. Always use cookware.
• Do not use the glass cooktop surface as a cutting board.
• Do not place any cookware, utensils, or leave excess water spills on
control key pads. This may result in unresponsive touch pads and
turning off the cooktop if present for several seconds.
• Do not slide metal or glass across the cooktop surface. Cookware with
rough or uneven bottoms can mark or scratch the cooktop surface.
• Do not place sealed containers on the cooktop.
• Do not place aluminum foil or plastic items such as salt and pepper
shakers, spoon holders, or plastic wrappings or any other material on
the cooktop when it is in use.
• Do not turn surface units on before placing cookware.
• Always turn the surface units off before removing cookware.
• The surface element may appear to have cooled after it has been
turned off. The element may still be hot and touching the element
before it has cooled sufficiently can cause burns.
• Only certain types of glass, glass-ceramic, ceramic, earthenware, or
other glazed cookware are suitable for cooktop service without
breaking due to the sudden change in temperature.
• Choose proper heating element size. For smaller pots and pans, use the
smaller heating elements. For larger pots and pans, use the larger
heating elements. Select pans that have flat bottoms large enough to
cover the heating elements. Using undersized pans exposes a portion of
the heating element to direct contact and may result in clothing
burning.
• Immediately clean spills on the cooking area to prevent a tough
cleaning chore later.
• Do not use a steel-wool pad or scrub pad or abrasive cleaning pads.
They can scratch the surface.
CAUTION
34
COOKING AREAS
The cooking areas on your cooktop are identified by permanent circles on the
glass cooktop surface.
For the most efficient cooking, fit the pan size to the element size. Pans should
not extend more than 1/2" to 1" beyond the cooking area.
When a control is turned on, a glow can be seen through the glass cooktop
surface.
NOTE:
• It is normal for the cooktop elements to cycle on and off during
cooking, even on higher settings.
• Do not place hot cookware over the keypads or indicator lights in the
control panel. Placing hot cookware on the control panel can damage
the electronic underneath.
35
HOT SURFACE INDICATOR
The element display next to the element keypad shows "H" after the element
is turned off, and indicates that element surface is still hot. When the surface
has cooled to approximately 150°F and the hot surface indicator "H"
disappears in the element display, the glass surface may still feel slightly hot
to touch.
USING THE COOKTOP ELEMENTS
The cooktop elements have a 2-hour heating time limit, after which the
control will automatically turn off the elements to avoid the elements being
left on accidentally. If desired, the cooktop elements can be restarted after
the time limit expires.

USING THE PROPER COOKWARE
The size and type of cookware will influence the settings needed for the best
cooking results. Cookware should have flat bottoms that make good contact
with the entire surface heating element.
Cookware Recommendations
NOTE:
• Flat bottom and straight sides
• Heavy-gauge pans
• Pan sizes that match the amount of food to be prepared and the size of
the surface element
• Weight of handle does not tilt pan. Pan is well balanced
• Tight-fitting lids
• Flat bottom woks
• Do not use woks that have support rings. This type of wok will not heat
on glass surface elements.
• Do not use foil or foil-type containers. Foil may melt onto the glass. Do
not use the cooktop if metal has melted on it.

to turn off the
38
Choosing Cookware
The cookware material determines how evenly and quickly heat is transferred
from the surface element to the pan bottom.
Recommended
• Aluminum - Excellent heat conductor. Some types of food will cause
it to darken (anodized aluminum cookware resists staining and
pitting). If aluminum pans slide across the ceramic cooktop, they may
leave metal marks which will resemble scratches. Remove these
marks immediately. Because of its low melting point, thin weight
aluminum should not be used.
• Copper - Excellent heat conductor but discolors easily. May leave
metal marks on glass-ceramic (see Aluminum above). Do not let
these pots boil dry. Overheated metal can bond to glass cooktops.
An overheated copper bottom pot will leave a residue that will
permanently stain the cooktop if not removed immediately.
• Stainless Steel - Slow heat conductor with uneven cooking results. Is
durable, easy to clean and resists staining.
• Enamel (painted) on Cast Iron - Bottom of pan must be smooth
coated and smooth.
Not Recommended
• Enamel (painted) on Steel - Heating empty pans can cause
permanent damage to cooktop glass. The enamel can melt and
bond to the ceramic cooktop.
• Cast iron - A poor heat conductor, slow to absorb heat but retains
heat very well. Will scratch the glass surface. Not recommended
unless designed specifically for use on ceramic cooktops.
• Glass-ceramic - Slow heat conductor. Poor performance, and will
scratch the glass surface.
• Stoneware - Poor performance, and may scratch the glass surface.

COOKTOP CARE AND MAINTENANCE
CLEANING
IMPORTANT:
• Before cleaning, make sure all controls are off and the cooktop is cool.
• Always follow label instructions on cleaning products. Soap, water and a
soft cloth or sponge are suggested first unless otherwise noted.
• Do not use abrasive cleaning products.
GENERAL CLEANING
• Before using the cooktop for the first time, clean it with a ceramic cooktop
cleaner. This helps protect the top and makes cleanup easier.
• Regular use of ceramic cooktop cleaner will help keep the cooktop
looking new.
• If any sugar or food containing sugar spills, or plastic or foil melts on the
cooktop, remove the material IMMEDIATELY with a metal razor scraper
while the cooking surface is still hot to avoid the risk of damage to the
glass-ceramic surface. When used correctly, the scraper will not damage
the cooktop surface.
• For your safety, please use an oven mitt or pot holder while scraping the
hot cooking surface.
• If water or food containing water spills, remove the spill IMMEDIATELY
with a dry paper towel.
• Do not use scrub pads or abrasive cleaning pads. They may damage your
cooktop surface.
Cleaning Method:
• Use ceramic cooktop cleaner on the glass cooktop. Other creams may not
be as effective or may scratch, damage or stain the cooktop surface.
• Use a paper towel or non-scratch cleaning pad to clean the entire
cooktop surface.
• Rinse with clear water and use a dry cloth or paper towel to remove all
cleaning residue.
40
NOTE:
• Any damage or failure of the product resulting from the items
below may not be covered under the Limited Warranty.
- Sugary spillovers (such as preserves, ketchup, tomato sauce,
jellies, fudge, candy, syrups, or chocolate) or melted plastics
can cause pitting on the surface of your cooktop.
- If food or water containing calcium (such as baking powder,
wine, milk, spinach, or broccoli) is spilled on the cooktop, it can
permanently stain or discolor the surface.
BURNED-ON RESIDUE
• Allow the cooktop to cool.
• For additional protection, after all residue has been removed, polish the
entire surface with ceramic cooktop cleaner and a paper towel.
Cleaning Methods:
• Spread a few drops of ceramic cooktop cleaner on the entire burned
residue area. Using a non-scratch cleaning pad for ceramic cooktops, rub
the residue area, applying pressure as needed. Leave the cleaner on for
10 minutes before rinsing it off.
• Rinse with clear water and wipe the cooktop surface with a clean, dry
paper towel. If any residue remains, repeat the steps listed above as
needed.
NOTE:
• Damage to your glass surface may occur if you use scrub pads
other than those recommended.
HEAVY BURNED-ON RESIDUE
• Allow the cooktop to cool.
• For additional protection, after all residue has been removed, polish the
entire surface with ceramic cooktop cleaner and a paper towel.
41
Cleaning Methods:
• While the cooktop is still warm, use a single-edge razor blade scraper at
approximately a 30° to 45° angle against the glass surface and scrape
the soil. It will be necessary to apply pressure to the razor scraper in order
to remove the residue.
• When the cooking surface is completely cooled, spread a few drops of
ceramic cooktop cleaner on the entire burned residue area. Using a non-
scratch cleaning pad for ceramic cooktops, rub the residue area, applying
pressure as needed. Leave the cleaner on for 10 minutes before rinsing it
off.
• Rinse with clear water and wipe the cooktop surface with a clean, dry
paper towel.
NOTE:
• Do not use a dull or nicked blade.
METAL MARKS AND SCRATCHES
• Cookware with rough or uneven bottoms can mark or scratch the cooktop
surface. Carefully check the bottom of pans.
• Do not slide metal or glass across the cooktop surface.
• Do not use cookware with any dirt build-up on the bottom.
• Always clean the cooktop surface before cooking.
• Be careful not to place aluminum baking sheets or aluminum frozen
entrée containers on a hot cooktop surface. It will leave shinny dots or
markings on the cooktop surface. These markings are permanent and
cannot be cleaned off.
Cleaning Methods:
• Be careful not to slide pots and pans across your cooktop. It will leave
metal markings on the cooktop surface. These marks are removable using
the ceramic cooktop cleaner with a non-scratch cleaning pad for ceramic
cooktops.
• If pots with a thin overlay of aluminum or copper are allowed to boil dry,
the overlay may leave black discoloration on the cooktop. This should be
removed immediately before heating again or the discoloration may be
permanent.
