Caution - Hot

Control Knobs The controls on the cooktop are marked to show which element they control. All

controls are marked from 1-9, with 1 being the lowest heat setting and 9 the high­est setting.

Using the Cooktop

Before Using the Cooktop for the First Time

Remove all packing materials and literature from the cooktop surface.
While cool, wipe with a clean, damp sponge and dry.
Apply the Cooktop Cleaning Creme® packaged with the cooktop. Buff with a clean cloth.
There may be a slight odor during the first several uses; this is normal and will disappear.
Optimum cooking results depend on the proper cookware being selected and used.
The cooking surface will hold the heat and remain hot up to 25 or 30 minutes after the elements have been turned off.
Read all safety precautions and Use and Care Manual information prior to operating.
English 3

Precautions for Long Life and Good Appearance of the Surface

Regular, daily care using the Cooktop Cleaning Creme® will protect the sur­face and make it easier to remove food soil and water spots.
The glass ceramic cooking surface is a durable material resistant to impact but not unbreakable if a pan or other object is dropped on it.
Do not use aluminum foil directly on the glass; it will melt and damage the glass surface.
Do not allow plastic, paper, or cloth to come in contact with the hot glass sur­face; these items can melt or burn and damage the glass surface.
Do not allow pans to boil dry. This can damage the pan, element and/or the cooktop.
Never cook food directly on the glass.
Avoid placing a wok support ring, trivet or other metal stand on the glass sur­face.
Do not use the glass surface as a cutting board.
Do not slide cookware across the cooking surface; it may scratch the glass.
Do not place wet pans on the glass surface.

Operation

Radiant Elements This type of electric element uses a wire ribbon located under the ceramic glass

surface to provide the heat for cooking. Radiant elements will cycle on and off by design (see Temperature Limiters, below.) There are an infinite number of heat settings between the 1-9 positions.

Single Element To turn on a single element, push down on the control knob and turn in either

direction to the desired heat setting.

Dual Element The dual element consists of two radiant ribbon elements within the same heating

area. Either the small inner element or both the inner and outer elements may be selected for use.
To turn ON the small, inner element, push down on the control knob and turn it clockwise. Set to desired heat level.
To turn ON both the inner and outer elements together, push down on the control knob and turn it clockwise past the number 9 setting to the dual element marker. The dual ON indicator light will glow indicating that the dual element is on. Turn the knob counterclockwise to the desired setting. To turn off the dual element, turn the knob to the OFF position.

Temperature Limiters Each radiant heating element has its own sensor to protect the glass cooking sur-

face from extreme high temperatures. The limiters will operate automatically by cycling the element off regardless of the cook setting.
Although cycling is normal, any one of the following conditions can activate the limiter and cause it to cycle on and off more than usual:
The base of the pan is not making full contact with the heating surface (due to a warped or uneven base).
The pan is too small for the size of the element.
The pan has boiled dry.
The material or shape of the pan is slow to transfer the heat.

Retained Heat CAUTION: The glass cooking surface retains heat and stays hot after

the element(s) have been turned off. The retained heat may be used to hold foods at serving temperatures for a short time.

Note for Owners of White Cooktops When an element is hot, there is a light green tint on the cooking surface. This is

normal and will disappear after several minutes as the surface cools down.

Getting the Most Out of Your Cooktop

Proper Cookware

Cookware Characteristics The choice of pans directly affects the cooking speed and uniformity. For best

results select pans with the following features:
Flat Bases
When a pan is hot, the base (pan bottom) should rest evenly on the surface with­out wobbling (rocking). Flat, medium-to-heavy-weight pans are best.
To test the flatness of your pans:
Turn the pan upside down on the countertop and place a ruler flat against the bot­tom of the pan. The bottom of the pan and the straight edge of the ruler should be flush against each other.
Another simple test to determine even heat distribution across the cookware bot­tom is to place 1” (25.4 mm) of water in the pan. Bring the water to a boil and
English 5
observe the location of the bubbles as the water starts to boil. Good, flat cookware will have an even distribution of bubbles over the bottom surface area.
Figure 6 - Testing Flatness
Diameter
The base of the pan should cover or match the diameter of the element being used. Pans may overhang the element area by 1" (25.4 mm) all around.
Tight Fitting Lid
A lid shortens cooking time by holding the heat inside the pan.
Specialty Pans
Specialty pans, such as griddles, roasters, pressure cookers, woks, water bath canners and pressure canners must have the same features as described above. (Use only a flat-bottom wok.) Never place a support ring, such as a wok ring or trivet, on the cooking surface.

Cookware Practices Use of pots and pans with rounded (either concave or convex) warped or

dented bottoms should be avoided. See drawings above. • Make sure the bot­tom of the pot or pan being used is clean and dry.
Use pots and pans with thick, smooth metal bottoms. • Do not slide metal pots across the cooktop. Pans may leave marks.
Do not use glass pans as they may scratch the surface.
Figure 7 - Good Practices
CAUTION:
Foods packaged in aluminum foil should not be placed directly on the glass ceramic surface for cooking; aluminum foil can melt and cause permanent damage.
Plastic, paper and cloth can melt or burn when in contact with a hot surface. Do not let these items come in contact with the hot glass ceramic surface.
Do not allow pans to boil dry. This can permanently damage the pan, the ele­ment and the cooktop glass.

A range of heat settings are listed because the actual setting depends on:

1. type and quality of pan

2. type, quantity and temperature of the food

3. element used

4. the cook’s preference.

208/240 Volt Connection The Heat Settings recommended on this page are based on a 240 volt power

source. If your cooktop is connected to 208 volts, the same heat settings apply but foods may take a little longer to finish cooking.

Care and Cleaning

Before Use Care Care is easy when preventative steps are taken. For example, apply a small

amount of Cooktop Cleaning Creme® (packaged with cooktop) on a daily basis. This provides a protective film that makes it easy to remove water spots or food spatters. The temperature of the cooking surface reduces the protective qualities of this cleaner. It must be reapplied before each use. Use a clean cloth and apply Cooktop Cleaning Creme® before each use to remove dust or metal marks that can occur on the counterlevel surface between uses.

Caustic Cleaners Oven cleaners such as Easy Off® may etch the cooktop surface.
Abrasive Cleaners
Metal scouring pads and scrub sponges such as Scotch Brite® can scratch and / or leave metal marks.
Soap-filled scouring pads such as SOS® can scratch the surface.
Powdery cleaners containing chlorine bleach can permanently stain the cook­top.
Flammable cleaners such as lighter fluid or WD-40.

Daily Cleaning Techniques 1. Clean the surface when it is completely cool with the following exception:

remove Dry Sugar, Sugar Syrup, Tomato Products and Milk immediately with the razor blade scraper.
Figure 8 - Scraper
CAUTION: Do not use any kind of cleaner on the glass while the sur-
face is hot; use only the razor blade scraper. The resulting fumes can be hazardous to your health. Heating the cleaner can chemically attack and damage the surface.

2. Wipe off spatters with a clean, damp sponge or paper towel. Rinse and dry. Use white vinegar if smudge remains; rinse.

Surface scratches
Small scratches are to be expected on the glass surface, but do not affect cooking. In time, small scratches will become smoother and much less noticeable with daily use of the Cooktop Cleaning Creme.
Apply Cleaning Creme before using to remove sand-like grains and grit such as salt and seasoning.
Can be reduced by using pans with bases that are smooth, clean, and dry before use. Use recommended Cooktop Cleaning Creme daily on the cooktop.
Be Careful: Diamond rings will scratch the surface.
