WARNING • This appliance is intended for normal residential use. It is not approved for commercial use, outdoor installation, or any other application not specifically allowed by this manual. • This appliance requires connection to a 3-prong or 4-prong, 240VAC single-phase (split-phase), 60Hz grounded electrical source. When installed, appliance must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, NFPA 70 or CSA Standards C22.
IMPORTANT SAFETY INSTRUCTIONS WARNING: To reduce the risk of fire, electrical shock, injury to persons, or damage when using the cooktop, follow basic precautions, including the following: • For Personal Safety, remove house fuse or open circuit breaker before beginning installation. Failure to do so could result in serious injury or death. - Aluminum to Copper wiring connections must conform with the National Electrical code, local codes and industry-accepted wiring practices.
IMPORTANT SAFETY INSTRUCTIONS • Be sure your appliance is properly installed and grounded by a qualified technician. • To eliminate the risk of burns or fire due to reaching over heated surface elements, cabinet storage located above the surface units should be avoided. If cabinet storage space is to be provided, the risk can be reduced by installing a range hood that projects horizontally a minimum of 5" beyond the bottom of the cabinets. Cabinet installation above the cooktop may be no deeper than 13".
IMPORTANT SAFETY INSTRUCTIONS • 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 other flammable materials contact surface units or areas near units until they have had sufficient time to cool. Among these areas are the coil elements, the cooktop, and surfaces facing the cooktop.
IMPORTANT SAFETY INSTRUCTIONS • Glazed Cooking Utensils – 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.
IMPORTANT SAFETY INSTRUCTIONS • Proper Disposal of Your Appliance – Dispose of or recycle your appliance in accordance with Federal and Local Regulations. Contact your local authorities for the environmentally safe disposal or recycling of your appliance. For units with ventilating hood – • Clean Ventilating Hoods Frequently – Grease should not be allowed to accumulate on hood or filter. • When flaming foods under the vent hood, turn the fan on.

OPERATION BEFORE USING THE COOKTOP Read all instructions before using. WARNING • 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.
CAUTION • 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.
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.
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.
Turning on the Triple Element 1. Touch the power keypad cooktop. for approximately 3 seconds to turn on the 2. Activate the triple element: - Touch the triple element keypad element. to activate the inner most - Touch the triple element keypad again to activate the inner most and middle elements (Dual Element). One indicator light at the triple element keypad will turn on. - Touch the triple element keypad again to activate the entire element (Triple Element).
for that element 5. To turn off an element, touch the element keypad again if any other element keypads were touched and touch 0 on the to turn off the element power settings, or touch the power keypad cooktop. The element display next to the element keypads will show "H" and indicate the element surfaces are still hot. USING THE PROPER COOKWARE The size and type of cookware will influence the settings needed for the best cooking results.
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.
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.
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.
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 nonscratch cleaning pad for ceramic cooktops, rub the residue area, applying pressure as needed.
TROUBLESHOOTING First try the solutions suggested here to possibly avoid the cost of a service call. COOKTOP PROBLEMS PROBLEM POSSIBLE CAUSE SOLUTION Surface units do not work properly There is no power to the cooktop. Make sure electrical plug is plugged into a live, properly grounded outlet. Replace the fuse or reset the circuit breaker. Cooktop controls improperly set. Check to see the correct control is set for the surface unit you are using.
PROBLEM POSSIBLE CAUSE SOLUTION Unable to maintain a rolling boil or will not cook fast enough Using improper cookware. Use pans with flat bottoms and that match the diameter of the cooktop element selected. See the "Using The Proper Cookware" section. Using large cookware without lid. Large pots and pans can lose a lot of heat from the top. Cover pot or pan with a lid to retain heat better. Food spillovers not cleaned before next use. See the "Cleaning" section. Cooktop is not cleaned thoroughly.
