SAFETY & WARNINGS

SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.

This is the safety alert symbol.

This symbol alerts you to potential hazards that can kill or hurt you and others.

All safety messages follow the safety alert symbol and one of the following words:

DANGER!: You can be killed or seriously injured if you do not immediately follow instructions.
WARNING!: You can be killed or seriously injured if you don’t follow instructions.
CAUTION!: Hazards or unsafe practices COULD result in minor personal injury if you don’t follow instructions.

Always read and obey all safety messages.

WARNING!: To reduce the risk of fire, electrical shock, injury to persons, or damage when using the cooktop, follow basic precautions, including the following safety and warnings.
CAUTION!: DO NOT store items in cabinets above the cooktop that is of interest to children. Children climbing on the cooktop to reach items could be seriously injured.

THIS PRODUCT IS INTENDED FOR HOUSEHOLD USE ONLY.

Be sure your cooktop is properly installed and grounded by a qualified technician.
DO NOT repair or replace any part of the cooktop unless specifically recommended in the manual. All other servicing SHOULD be referred to a qualified technician.
Wear proper apparel. Loose-fitting or hanging garments SHOULD NEVER be worn while using the cooktop.
DO NOT store flammable materials near cooktop or surface burners.
Only certain types of glass, glass/ ceramic, ceramic, earthenware, or other glazed utensils are suitable for cooktop service without breaking due to the sudden change in temperature.
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.
DO NOT use water on grease fires. Smother fire or flame or use dry chemical or foam-type extinguisher.
NEVER leave surface units unattended at high heat settings. Boilover causes smoking and greasy spillovers that may ignite.
Children SHOULD NOT be left alone or unattended in the area where the cooktop is in use.
They SHOULD NEVER be allowed to sit or stand on any partof the cooktop.
DO NOT touch surface units or areas near units. Surface units may be hot even though they are dark in color. Areas near surface units may become hot enough to cause burns.
During and after use, DO NOT touch, or let clothing or otherflammable materials contact surface units or areas near units until they have had sufficient time to cool. Among those areas are the cooktop and surfaces facing the cooktop.
Use proper pan size. This cooktop is equipped with one or more surface units of different sizes.
Select cookware has flat bottoms large enough to cover the surface unit heating element. The use of undersized cookware will expose a portion of the heating element to direct contact and may result in the ignition of clothing. Proper sizing of cookware to burners will also improve efficiency.
Use only dry potholders. Moist or damp potholders on hot surfaces may result in burns from steam.
DO NOT let potholder touch hot heating elements. DO NOT use a towel or other bulky cloth.
DO NOT COOK ON A BROKEN COOKTOP. If the cooktop should break, cleaning solutions and spillovers may penetrate the broken cooktop and create a risk of electric shock. Contact a qualified technician immediately.
NEVER use your cooktop for warming or heating the room.
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.
Extreme caution SHOULD be exercised when using cookware or bakeware constructed of anything other than ovenproof metal or glass.
DO NOT place any of the following materials in the oven: cardboard, plastic, paper, or anything similar.

---|---

Cooktop Control Knob

The control knobs can be set to anywhere between LOW and HIGH. Push in and turn the control knob to set the desired heat level.

Surface Cooking Area Locator

The surface cooking area locator shows which burner element is turned on.
Use the following chart as a guide when setting heat levels.

WARNING!: When cooktop is in use, the entire cooktop area may become hot.

SETTING	RECOMMENDED US
High

Start cooking food.
Bring liquid to a boil.

Medium High|

Hold a rapid boil.
Quickly brown of sear food.

Medium|

Maintain a slow boil.
Fry or saute foods.
Cook soups, sauces and gravies.
High simmer or simmer without lids.

Medium Low|

Stew or steam food.
Simmer.

Low|

Keep food warm.
Melt chocolate or butter.
Low simmer using lids.

Dual Elements|

Home canning.
Large-diameter cookware.
Large quantities of food

DUAL ZONE ELEMENT

The Dual Zone elements offer flexibility depending on the size of the cookware. A Single Zone element can be used in the same way as a regular element. The Dual Zone element combines single and dual elements and is recommended for larger cookware, large quantities of food, and home canning. The Dual Zone element must have Dual Mode activated before it can be used.

To use the Single Zone element:

Push in and turn Control Knob from the OFF position to anywhere between LO and HI to adjust cooking temperature.
Turn knob to OFF when finished.

To activate DUAL MODE for the Dual Zone element:

Push in and turn the Control Knob clockwise from the OFF position, past HI / DUAL MODE position, towards the symbol (See Knob Diagram).
The Control Knob will click then retract back to the HI / DUAL MODE position; Dual Mode is now activated.
Use the Control Knob to anywhere between LO and HI to adjust cooking temperature.
To deactivate Dual Mode, turn the Control Knob to the OFF position. You may then restart the burner to use the Single Zone element.

For best High heat performance, match the burner to cookware size.
For best Low heat or Simmer performance, match cookware to the largest cooking area ring and use a single ring for desired performance.

HOT SURFACE INDICATOR LIGHT

This unit features a Hot Surface Indicator Light.
The Hot Surface Indicator Light will glow as long as any surface cooking area is too hot to touch, even after the surface cooking area(s) is turned off.

CERAMIC GLASS COOKTOP SURFACE

The surface cooking area will glow red when an element is on. Some parts of the surface cooking area may not glow red when an element is on; this is normal. The burner will cycle on and off to maintain the selected heat level. It will also randomly cycle off and back on again, even while on High, to keep the cooktop from extreme temperatures. It is normal for the surface of the light-colored ceramic glass to appear to change color when surface cooking areas are hot. As the glass cools, it will return to its original color.

Cleaning off the cooktop before and after each use will help keep it free from stains and provide the evenest heating. On cooktops with light-colored ceramic glass, soils and stains may be more visible and may require more cleaning and attention. A cooktop cleaner and a cooktop scraper are recommended. For more information, see “Care & Maintenance”,

Avoid storing jars or cans above the cooktop. Dropping a heavy or hard object onto the cooktop could crack the cooktop.
To avoid damage to the cooktop, do not leave a hot lid on the cooktop. As the cooktop cools, air can become trapped between the lid and the cooktop, and the ceramic glass could break when the lid is removed.
For foods containing sugar in any form, clean up all spills and soils as soon as possible. Allow the cooktop to cool down slightly. Then, while wearing oven mitts, remove the spills using a scraper while the surface is still warm. If sugary spills are allowed to cool down, they can adhere to the cooktop and can cause pitting and permanent marks.
To avoid scratches, do not slide cookware or bakeware across the cooktop. Aluminum or copper bottoms and rough finishes on cookware or bakeware could leave scratches or marks on the cooktop.
Do not cook popcorn in prepackaged aluminum containers on the cooktop. It could leave aluminum marks that cannot be removed completely.
To avoid damage to the cooktop, do not allow objects that could melt, such as plastic or aluminum foil, to touch any part of the entire cooktop.
To avoid damage to the cooktop, do not use the cooktop as a cutting board.
To avoid damage to the cooktop, do not cook foods directly on the cooktop.
Use flat-bottomed cookware for best heat conduction and energy efficiency. Cookware with rounded, warped, ribbed, or dented bottoms could cause uneven heating and poor cooking results. Determine flatness by placing the straight edge of a ruler across the bottom of the cookware. While you rotate the ruler, no space or light should be visible between it and the cookware.
Cookware designed with slightly indented bottoms or small expansion channels can be used.
Make sure the bottoms of pots and pans are clean and dry before using them. Residue and water can leave deposits when heated.

COOKWARE

CAUTION!: Do not leave empty cookware on a hot surface cooking area, element or surface burner.

Ideal cookware should have a flat bottom, straight sides, and a well-fitting lid and the material should be of medium-to-heavy thickness.
Rough finishes may scratch the cooktop. Aluminum and copper may be used as a core or base in cookware. However, when used as a base they can leave permanent marks on the cooktop or grates.
Cookware material is a factor in how quickly and evenly heat is transferred, which affects cooking results. A nonstick finish has the same characteristics as its base material. For example, aluminum cookware with a nonstick finish will take on the properties of aluminum.

Use the following chart as a guide for cookware material characteristics:

COOKWARE

|

CHARACTERISTICS

---|---
Aluminum|

Ceramic or Ceramic Glass|

Follow cookware manufacturer’s instructions
Heats slowly, but unevenly.
Ideal results on low to medium heat settings.

Copper|

Heats very quickly and evenly.

Earthenware|

Follow cookware manufacturer’s instructions.
Use on low heat settings.

Porcelain enamel- on-steel or cast iron|

See stainless steel or cast iron.

Dual Elements|

Heats quickly, but unevenly.
A core or base of aluminum or copper on stainless steel provides even heating.

HOME CANNING

When canning for long periods, alternate the use of surface cooking areas, elements, or surface burners between batches. This allows time for the most recently used areas to cool.

Center the canner on the grate or largest surface cooking area or element. On electric cooktops, canners should not extend more than ½” (1.3 cm) beyond the surface cooking area or element.
Do not place canner on 2 surface cooking areas, elements, or surface burners at the same time.
On ceramic glass models, use only flat-bottomed canners.

For more information on home canning, contact your local agricultural department; companies that manufacture home canning products can also offer assistance.

CARE & MAINTENANCE

IMPORTANT!: Before cleaning, make sure all controls are off and the oven and cooktop are cool. Always follow label instructions on cleaning products.

General Cleaning

Soap, water and a soft cloth or sponge are suggested first unless otherwise noted.

Ceramic Glass Cleaning

Always wipe with a clean, wet cloth or sponge and dry thoroughly to avoid streaking and staining. To avoid damage to the cooktop, do not use steel wool, abrasive powder cleansers, chlorine bleach, rust remover or ammonia.

Light to moderate soil: Paper towels or clean damp sponge. Sugary spills (jellies, candy, syrup)
o Cooktop Scraper: Clean while the cooktop is still warm. Wear heat-resistant oven mitts while doing so.
o Cooktop Polishing Creme and clean damp paper towel: Clean as soon as cooktop has cooled down. Rub creme into surface with a damp paper towel or soft cloth. Continue rubbing until white film disappears.
Heavy soil, dark streaks, specks and discoloration: Use Cooktop Polishing Creme or nonabrasive cleanser; rub product into soil with a damp paper towel or soft cloth. Continue rubbing until white film disappears.
Burned-on soil: Use Cooktop Polishing Creme and Cooktop Scraper; rub creme into soil with damp paper towel. Hold scraper as flat as possible on surface and scrape. Repeat for stubborn spots. Polish entire cooktop with creme and paper towel.
Metal marks from aluminum and copper: Use Cooktop Polishing Creme; clean as soon as cooktop has cooled down. Rub creme into surface with a damp paper towel or soft cloth. Continue rubbing until white film disappears. The marks will not totally disappear but after many cleanings become less noticeable.
Tiny scratches and abrasions: Use Cooktop Polishing Creme; rub creme into surface with a damp paper towel or soft cloth. Continue rubbing until white film disappears. Scratches and abrasions do not affect cooking performance and after many cleanings become less noticeable.

Cooktop Knob Cleaning

When replacing knobs, make sure knobs are in the OFF position. On some models, do not remove seals under knobs. To avoid damage to the cooktop controls, do not use steel wool, abrasive cleansers or oven cleaner, and do not soak knobs.
