appliance.
• Never place combustible items on the cooktop.
• Never keep any combustible items or aerosol cans in a drawer located under the cooktop.
• When heating fat or grease, watch it closely. Fat or grease may catch fire if allowed to become too hot.
• Overheated fats and oils catch fire quickly. You should supervise cooking when preparing foods in fat or
oil.
• Use a deep fat thermometer, if possible, to prevent overheating fat beyond the smoking point.
• If the surface is cracked, switch off the appliance to avoid the possibility of electric shock. Do not reuse
your cooktop until the glass surface has been replaced.
• When using the cooktop, never use aluminum foil, products wrapped in aluminum foil, or deep-frozen
food in aluminum cookware.
• 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.
• Items of interest to children should not be stored in cabinets above a cooktop or on the backsplash of a
cooktop – children climbing on the cooktop to reach items could be seriously injured.
• Children should not be left alone or unattended in the area where an appliance is in use. They should
never be allowed to sit or stand on any part of the appliance.
• Take care when plugging in electric appliances near the cooktop. Cords must not come into contact with
the hot surface. Doing so could cause damage to the cooktop and cable insulation.
• After use, switch off the cooktop element by its control and do not rely on the pan detector.
• Avoid placing metal objects such as knives, forks, spoons and lids on the cooking surface areas. Metal
objects can become hot and cause burns.
• Do not place any object on or near the display area in order to prevent accidental activation of the
cooktop controls.
• Cookware 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
cookware, the handles of cookware should be positioned so that they are turned inward, and do 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.
• 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.

5IMPORTANT SAFETY INSTRUCTIONS
ENGLISH
• Do not clean or operate a broken cooktop. If the cooktop breaks, cleaning solutions and spillovers may
penetrate the broken cooktop and create a risk of electric shock. Contact a qualified technician
immediately.
• Never leave surface units unattended at high heat settings. Boilover causes smoking and greasy
spillovers that may ignite.
• Always turn off all controls when cooking is completed.
• Keep pets away from the product to avoid risk of fire or burns. Do not allow pets to climb on the product
even when it is not in operation.
• Liquids such as water, coffee or tea are able to be overheated beyond the boiling point without
appearing to be boiling, due to surface tension of the liquid. Visible bubbling or boiling is not always
present when the container is removed from the cooktop. This could result in very hot liquids suddenly
boiling over when the container is disturbed or a spoon or other utensil is inserted into the liquid. To
reduce the risk of injury to persons:
- Do not overheat the liquid.
- Stir the liquid both before and halfway through heating it.
- Do not use straight-sided containers with narrow necks.
- After heating, allow the container to stand on the cooktop for a short time before moving the
container.
- Use extreme care when inserting a spoon or other utensil into the container after heating.
• Do not use the cooktop as a work surface or storage space.
• 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.
Maintenance
• Do not repair or replace any part of the appliance. All servicing should be done only by a qualified
technician to avoid the risk of personal injury and damage to the appliance.
• Take care to avoid steam burns if using a wet sponge or cloth to wipe spills on a hot cooking area.
• Wait for the cooktop to cool before using cooktop cleaners. Some cleaners can produce NOXIOUS
FUMES if applied to a hot surface.
• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
• If your appliance malfunctions or fractures, switch off all cooking zones, and contact an LG Customer
Information Center for service.
• Always keep the control panel clean and dry. Do not let liquids or grease remain on the cooktop display
area. Spilled or burnt-on foods can activate or deactivate the appliance. Clean the display area
thoroughly to resume normal operation of the appliance.
• 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 the hood or filters.
Greasy deposits in the fan could catch fire. Refer to the hood manufacturer's instructions for cleaning.

6IMPORTANT SAFETY INSTRUCTIONS
CAUTION STATEMENTS
CAUTION
• To reduce the risk of minor or moderate injury to persons, malfunction, or damage to the product or
property when using this product, follow basic precautions, including the following:
Operation
• This appliance may only be used for normal cooking and frying in the home. It is not designed for
commercial or industrial purposes.
• Use proper pan sizes. This appliance is equipped with one or more surface units of different sizes.
• Select cookware having flat bottoms large enough to cover the cooking zones.
• Only certain types of glass, glass/ceramic, ceramic, earthenware, or other glazed cookware are suitable
for rangetop service without breaking due to the sudden change in temperature. Check the
manufacturer’s recommendations for cooktop use.
• Do not place hot cookware on cold cooktop glass. This could cause the 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.)
• Cook meat and poultry thoroughly, meat to at least an INTERNAL temperature of 160 ℉and poultry to at
least an INTERNAL temperature of 180 ℉. Cooking to these temperatures usually protects against food-
borne illnesses.
• Prior to using the cooktop for the first time, apply the recommended cooktop cleaning cream to the
ceramic surface. Buff with a non-abrasive cloth or pad. This will make cleaning easier when the cooktop
gets soiled from cooking. The special cooktop cleaning cream leaves a protective finish on the glass to
help prevent scratches and abrasions.
• Please be careful of the cooktop edges when moving pots and pans.
• 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 the glass.
• Do not slide metal or glass across the cooktop surface.
• Do not use cookware with any dirt buildup on the bottom.
• Do not use cookware with rough or uneven bottoms. This cookware can mark and scratch the cooktop
surface.
• Do not use the glass cooktop surface as a cutting board.
Maintenance
• 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.
• 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 the cooktop cautiously. Do not use sponges or cloth to wipe spills on a hot cooking area. Use a
proper metal scraper.
• If sugar or a mixture containing sugar falls onto a hot cooking zone and melts, remove it with a metal
scraper immediately, while still hot. If left to cool down, it may damage the surface when removed. Use
caution and wear an oven mitt to avoid burns.

7IMPORTANT SAFETY INSTRUCTIONS
ENGLISH
SAVE THESE INSTRUCTIONS
• 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.
• Use oven mitts to avoid burns when using a metal scraper on a hot cooking zone.
• Refer to the Maintenance section for proper cleaning and maintenance of the cooktop.
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.

the Operating Instructions in this guide for details.

18 OPERATION
OPERATION
Cookware
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 inwards (concave). They should never be
bowed outwards (convex).
• When using specialty cookware such as pressure
cookers, simmering pans, or woks, 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.
Avoiding Scratches
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. 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 (for
example, after washing vegetables) which are
dragged with the pot across the cooking surface.
Using Cookware
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 element to the amount
of food being prepared.
Tips for Saving Energy
• Always position pots and pans before you switch
on the element.
