Electrical Requirements

GROUNDING SPECIFICATIONS

Ground Path Resistance 0.10 Ω Max. Insulation Resistance 250K Ω Min.

POWER SUPPLY REQUIREMENTS

The cooktop must be connected to a supply circuit of the proper voltage and frequency as speciﬁ ed on the nomenclature tag. Wire size must conform to the National Electrical Code or the prevailing local code. The nomenclature tag is located on the bottom of the burner box.

OVERCURRENT PROTECTION

Wall-Mounted Oven or Counter-Mounted Cooktops

The branch circuit load for 1 wall-mounted oven or 1 counter-mounted cooktop is the rating on the nomenclature tag of the appliance.

The branch circuit load for a counter-mounted cooktop and not more than 2 wall-mounted ovens― all supplied from a single branch circuit and located in the same room―shall be computed by adding the nameplate ratings on the individual appliances and treating this total as equivalent to 1 range.

WIRING

Built-in power leads are UL approved for connection to larger gauge household wiring. The insulation of these leads is rated at temperatures much higher than the temperature rating of household wiring. The current carrying capacity of a conductor is governed by the temperature rating of the insulation around the wire rather than the wire gauge alone.

WARNING: Improper connection of aluminum house

wiring to these copper leads can result in a serious problem. Use only connectors designed for joining copper to aluminum and follow the manufacturer’s recommended procedure closely.

WIRING REQUIREMENTS WARNING: This appliance must be properly

grounded.

All cooktops must be hard wired (direct wired) into an approved junction box. The junction box must be easily reached through the front of the cabinet where the cooktop will be located. Allow considerable slack in the conduit for serviceability. A “plug and receptacle” is not permitted on these products.

You must use a 2-wire, 3-conductor, 208/240 VAC, 60 Hertz electrical system. A white (neutral) wire is not needed for this unit. The cooktop must be installed in a circuit that does not exceed 125 VAC nominal to ground.

Refer to the nomenclature tag on your cooktop for the KW rating for your cooktop.

The following MINIMUM clearance dimensions must be maintained.

If a 30-inch clearance between the cooking surface and overhead combustible materials or metal cabinets cannot be maintained, a minimum clearance of 24 inches is required and the underside of the cabinets above the cooktop must be protected with not less than ¼-in. insulating millboard covered with sheet metal not less than

0.0122 inches thick.

Overall Cooktop Dimensions - 36-in. Models

There must be 5 inches minimum vertical clearance between the cooktop bottom and any combustible surfaces.

Make sure the wall coverings, countertop and cabinets around the cooktop can withstand heat up to 200°F (93°C) generated by the cooktop.

W all covering, cabinets and countertop must withstand heat up to 200° F ( 93° C ).

Overall Cooktop Dimensions - 30-in. Models

Note: The junction box must be located where

it will allow considerable slack in the conduit for serviceability.

Using the surface elements.

Your new Profile Cooktop makes an eloquent statement of style, convenience, and kitchen planning flexibility. Whether you chose it for its purity of design, assiduous attention to detail, or for both of these reasons—you’ll find that your Profile cooktop’s superior blend of form and function will delight you for years to come.

The touch controls give you precise control of the surface elements. You can quickly switch between a steady low heat and full power or any setting in between. The information on the following pages will help you operate and maintain your cooktop properly.

NOTE: Throughout this manual, features and appearance may vary from your model.

Never cook directly on the glass. Always use cookware.

About the radiant surface elements…

The radiant cooktop features heating elements beneath a smooth glass surface.

Cooktop temperatures increase with the number of surface elements that are on. With 3 or 4 elements turned on, cooktop temperatures are high. Always use caution when touching it.

The indicator lights will come on next to the Dual and Tri-Ring burners when activated. Lights also activate for the Control Lock feature when it is turned on. The indicator lights will go off when the surface element or feature is turned off.

The appropriate HOT SURFACE indicator light will glow when its corresponding radiant element is turned on and will remain on until the surface has cooled to approximately 150°F.

NOTE:

Hot surface indicator light will:

■ Come on when the surface element is

turned on.

■ Stay on even after the element is turned off.

■ Glow brightly until the element has cooled

below 150°F.

NOTE: A slight odor is normal when a new cooktop is used for the first time. It is caused by the heating of new parts and insulating materials and will disappear in a short time.

It is safe to place hot cookware (from the oven or surface) on the glass cooktop when the surface is cool. Never place

cookware on the control area.

Even after the surface elements are turned off, the glass cooktop retains enough heat to continue cooking. To avoid overcooking, remove pans from the surface elements when the food is cooked. Avoid placing utensils that could become hot or plastics that could melt on the surface element until it has cooled completely .

■ Water stains (mineral deposits) are removable

using the cleaning cream or full strength white vinegar.

■ Use of window cleaner may leave an

iridescent film on the cooktop. The cleaning cream will remove this discoloration.

■ Don’t store heavy items above the cooktop.

If they drop onto the cooktop, they can cause damage.

■ Do not use the surface as a cutting board.

Do not slide cookware across the control or cooktop surface because it can scratch the glass. The glass is scratch-resistant, not scratchproof.

Radiant Surface Elements

The controls for the radiant surface elements allow for 11 different heat settings: Low , 1–9 and High. The heating element may not visibly glow at low heat settings.

The surface heating element will cycle on and off to maintain your selected control setting.

Each radiant surface element has a temperature limiter which protects the glass cooktop from getting too hot.
