Installation Instructions

6. Apply foam tape to the underside of the cooktop glass and flush with edge of the cooktop frame. The foam tape prevents sealant from seeping between the countertop and the underside of the cooktop. Service problems may arise if foam tape is not applied correctly.

7. Place metal reflective tape around the bottom inside edge of the cooktop cutout. This applies only to solid surface countertops.

8. Place cooktop in opening. The cooktop surface should be 1/16 inches higher than countertop surface. The 1/16 inch offset prevents hot cookware from coming in contact with the countertop surface.

9. Align cooktop in opening. There should be 1/16 inch clearance on all sides.

10. Using 3/4 inch masking tape, place a border around the edge of the cutout. This prevents sealant from sticking to the countertop.

11. Work in a well ventilated area when applying sealant. Apply the provided sealant into the 1/16 inch opening between the countertop and edge of cooktop, one side at a time. The sealant will begin to form a skin within 5 minutes. Wipe away excess sealant and smooth with a spatula or wet finger. Use only the sealant provided.

12. Do not touch sealant, move or use the cooktop for 24 hours. Protect the area from dust for at least 2 hours.

13. After 24 hours, clean up excess sealant on cooktop with razor blade and on countertop with a spatula.

Connecting Electrical Supply

Connect the lead wires from the cooktop conduit to the house feed wires inside the junction box. Connect red to red (120 VAC line), and black to black (120 VAC line). The neutral (if present) and ground wires are twisted together during manufacturing. One of the two following options should be used to ground the unit. Check local codes to determine which option should be used.

Option 1

Option 2

Attach the cooktop ground wire (green or bare) to the junction box (if grounded) or a suitable ground. Connect the cooktop ground wire (green or bare) to the house ground feed wire (green, bare, or white). If grounding through white wire, observe the following warning.

WARNING

To avoid risk of personal injury or electrical shock do not ground through the neutral wire if the installation is in a mobile home or if local codes do not permit grounding through a neutral.

Improper connection of aluminum house wiring to the copper leads can result in property damage, personal injury or fire. Use only connectors designed for joining copper to aluminum and follow the manufactures recommended procedure closely.

Place Cooktop in Cutout

Apply the foam gasket to the glass tops bottom edge before placing cooktop into its cutout.

1. Turn cooktop upside down. Do not rest cooktop on its knobs. Take care not to scratch the countertop.

2. Cut foam gasket to length for each edge. Apply one foam gasket strip for each edge.

3. Pull liner off foam gasket. Apply gasket to glass approximately 1/8 inch from the edge.

4. After foam gasket is applied to all four edges, place cooktop in cutout.

Checking for Proper Operation

1. Connect electrical supply at main circuit breaker.

2. Check each element for proper operation.

Removing and Replacing Cooktop

1. Disconnect electrical supply at main circuit breaker.

2. Disconnect unit from junction box.

3. Lift cooktop out of opening.

4. Replace the cooktop by following the instructions listed in this section or according to the Installation Instructions booklet included with the unit.

RS2420002 Rev. 59

Operating Instructions

Using the Cooktop

• Use Proper Pan Size Use cooking utensils with flat bottoms large enough to cover the flame. Correct-sized utensils improve cooking efficiency and promotes safety. Undersized utensils expose clothing and spillovers to direct flame.

• Never Leave Surface Units Unattended Boilovers can cause smoking or fire.

• Glazed Cooking Utensils Use glass, glass/ceramic, earthenware or other glazed utensils for cooking, although these products are not recommended on glass top cooktops. Sudden temperature changes may break some utensils and easily scratch cooktop if there are any imperfections in utensil bottom.

• Turn Utensil Handles Inward A handle extending from the cooktop invites accidents.

Cooking Utensils

Utensils made of different materials react differently to cooking temperatures. The best results occur by matching cooking utensil and cooking style. The following list describes the cooking characteristics of various materials.

• Aluminum responds quickly to temperature changes.

It responds best for frying, braising and roasting.

• Cast iron responds slowly to temperature changes. It

responds best for long low heat cooking and pan frying.

• Stainless steel combined with another metal such as

copper, responds better to temperature changes. Use stainless steel for soups, sauces, vegetables and general cooking.

• Copper, tin-lined utensils respond quickly to

temperature changes. It is excellent for gourmet cooking, wine sauces and egg dishes.

• Utensil design is important. Select utensils with flat

bottoms, straight sides, handle weight that does not tilt the pan, and pans that match the burner size. Do not use pans that exceed the diameter of the burner.

The following should not be used with cooktops.

• Glass/ceramic responds slowly to temperature

changes. It responds best to long and slow heating of liquids.

• Enamelware is stain resistant porcelain over metal.

The cooking time varies according to the base metal. Lower temperatures are usually recommended.

Using a Wok

Do not use a wok with a ring stand. A wok with a ring stand does not allow proper cooking. Use only a flat bottom wok.

Flat Bottom Wok

Ring Stand Wok

AKE Unit Description

AKE model cooktops feature four solid, cast iron elements. The heating coils beneath the elements are embedded in a insulated material, which protects the heating coils from damage and wear. This construction increases the elements durability. These elements are controlled by push-to turn control knobs that permit an infinite number of settings.

Each element has a built-in temperature limiter. The limiter prevents the surface temperature of an element from rising above 880°F. This temperature limiter is indicated by a red dot in the center of each element. The element will not get red hot (a temperature of 1000°F is needed for the element to glow), although the dots color changes slightly when it is heated. A low surface temperature decreases the risk of warping and/or melting down cookware that has boiled dry.

NOTE:

The solid element has twice the surface area of a conventional coil element and cooks by conduction rather than radiant heat.

The red dot will fade over time as a result of use and cleaning. This will not affect the performance of the element.

Operating Instructions

AKH, AK2H, CAK2H, and CAKH Unit Description

AKH and CAKH units feature one halogen element. AK2H units feature two Haloring elements reach cooking temperature quickly and provide an even heat. Both features improve cooking performance.

Halogen elements have two quartz halogen lamps which produce heat quickly and a glowing light when turned on. Halogen elements also use a resistance coil element. The coil element helps provide an even cooking heat. Haloring



elements feature a circular quartz halogen

bulb and a resistance coil. Non-halogen elements feature resistance coils designed

to provide a quicker and brighter visual response than that of conventional coil elements. These elements in some models are star shaped.

AKH and CAKH cooktops feature push-to-turn control knobs. These knobs permit an infinite number of settings. The elements cycle off and on to maintain the desired setting. Indicator lights glow red to indicate which surface areas are operating. After the elements are turned off, the indicator lights remain on until the cooking surface areas reach a safe temperature. A temperature limiter on each element protects the glass/ceramic cooktop from damage caused by overheating.

On the AK2H*2 and CAK2H*2 models, the two control knobs for the halogen burners have 10 settings which produce four visible brightness levels. The lowest setting offers only 5.5% of the maximum setting for a true low simmer. The other two control knobs operate the radiant elements and are infinite switches. These models, the AKH and CAKH also have dual Radiant element and a Quick Star Radiant element.

NOTE:

The halogen element will not be illuminated at settings LO through 3. The higher the selected temperature, the brighter the illumination from the element.

The halogen element will not cycle unless it has been left at a high heat setting for an extended amount of time without a pan in place or if the pan has boiled dry.

Turn control to OFF position, when finished.

Surface Element Hot Indicator Lights

Some cooktops feature four surface element indicator lights, some feature just one. On single indicator models, the hot indicator light glows red when any of the surface elements are turned on. On multiple light models, the hot indicator light glows red when the corresponding element is turned on. For all models, the surface indicator light remains on until the surface element reaches a safe temperature.

The four hot indicator lights featured on some models are located in the center of the control panel. The hot indicator lights glow red when the corresponding element is turned on. The light remains on until the corresponding element has cooled.

Changing Fuses−Canadian Models Before Date Code 2/96

The cooktop fuse box is located at the end of the power conduit. Turn the fuses counterclockwise to remove. Replacement fuses must have the same rating.

Cleaning

Do not clean cooktop until it cools. Sudden temperature changes can crack the cooktop surface. Washing the cooktop with hot, soapy water after each use minimizes the need for heavy cleaning. To preserve the original appearance, rinse and wipe the surfaces dry after washing. Wipe up marinades, fruit juices, vinegar and milk spills to avoid permanent stains. These materials contain acids and cause discoloration and permanent staining. DO NOT touch any portion of the cooktop when it is hot. Wait and wipe up spills after the cooktop is cool.

Troubleshooting Procedures

Cleaning Glass/ Ceramic Cooktop

Problem Cause To Prevent To Remove

Brown streaks and spots. Cleaning with a sponge or

dishcloth that has been used for other kitchen cleaning tasks and may contain soil−laden detergent water.

Blackened burned on spots. Spatters or spillovers onto

a hot cooking area.

Accidental melting of plastic film, such as a bread bag or similar item.

Fine “brown/gray lines (tiny scratches or abrasions which have collected soil).

Metal marking (gray or black marks).

Pitting or flaking. Boilover of sugar syrup

Hard water spots. In cooking, condensation

Coarse particles (salt, sand, sugar, or grit) caught between bottom of cookware and cooktop that are not removed before cooking. Using incorrect cleaning materials

Sliding or scraping metal utensils across cooktops.

often collects and drips from cookware covers removed during cooking. The minerals found in the water supply and acids in foods may spill on the surface and cause a gray deposit. The layer is so thin it often seems to be in or under the cooking surface and cannot readily be felt.

Use Elco, Bon Ami, Soft Scrub, Cooktop Cleaning Creme or baking soda only with a clean, damp paper towel.

Select correct heat settings and large enough cookware to eliminate boilovers and spatting. Whenever possible, wipe spatters and food spills as they occur. Use a spatter shield available in houseware departments and some supermarkets.

Do not put plastic items on or near warm cooking areas.

In areas where there is an abundance of sand or dust, be sure to wipe cooktop each time before using. Daily use of Elco, Bon Ami, Soft Scrub, Cooktop Cleaning Creme or baking soda. Do not slide metal objects across cooktop.

Select correct heat settings and large enough cookware to eliminate boilovers and spattering. Watch sugar syrup carefully to avoid boilover.

Daily use of Elco, Bon Ami, Soft Scrub, Cooktop Cleaning Creme or baking soda applied with a damp paper towel will help keep the glass/ceramic surface free from hard water mineral deposits and food causing discoloration.

Use a light application of Elco, Bon Ami, Soft Scrub, Cooktop Cleaning Creme or baking soda with a clean, damp paper towel.

Use Elco, Bon Ami, Soft Scrub, Cooktop Cleaning Creme or baking soda with a damp paper towel to remove as much burn on as possible. Use Elco, Bon Ami, Soft Scrub, Cooktop Cleaning Creme or baking soda with non-impregnated plastic nylon pads such as SCRUFFY scouring brush, TUFFY plastic meshball. If burn−on persists, carefully scrape with a single edge razor blade. Hold blade so entire length of edge is on cooktop at a 30° angle. Use a blade holder. Tiny scratches are not removable but can be minimized by continual use of Elco, Bon Ami, Soft Scrub, Cooktop Cleaning Creme or baking soda. Such scratches do not affect cooking performance.

Apply Cooktop Cleaning Creme, Bon Ami, Soft Scrub, or baking soda with a dampened paper towel to cooled surface. Turn unit to LO: take several paper towels and carefully wipe hot cooktop immediately. Scrape off remainder of burn with a single edge razor blade. Use a blade holder. Mix a small quantity of Bon Ami with tap water to form a thick wet paste. Apply this mixture to stained area. Scrub surface vigorously. If stain remains make a new paste and let it stand for thirty minutes. Then rescrub if necessary after stain is removed. Clean remaining paste away with damp paper towel.

Troubleshooting Procedures

Power Supply

If no part of the cooktop operates or only part of it operates, the cause may be a problem in the power supply.

1. Verify supply circuit breakers or fuses are not tripped. Check rating.

2. Disconnect power source. Check terminals at terminal block for tightness.

3. Verify cooktop service wires are properly connected. Be sure wires are in good condition. Check for continuity with an ohmmeter.

Internal Wiring

1. Disconnect power from cooktop.

2. Place one ohmmeter lead at terminal block. Place other lead at the line terminal of the non−functioning parts control. Meter should indicate continuity.

Use the appropriate wiring diagram to repeat this procedure from the output of the control to the next point until each wire section is checked. Often a visual check of the wiring will determine where a wiring fault is.

Surface Control

Power Connection

1. Refer to schematic diagrams for assistance in testing voltages in and out of control.

2. Connect a voltmeter to the element receptacle or the terminals H1 and H2 of the surface control.

3. Turn control to LOW setting and allow it to cycle approximately two minutes. Time the OFF and ON cycle of the control and compare these to the following table.

SETTING APPROXIMATE SECONDS

TIME ON OFF

LOW 3 20

MED 5 7

HIGH Constant 0

4. Replace the control if it is not cycling properly. Calibration is not possible.

A malfunction in the internal switching may fuse the cycling contacts. This causes the heating element to operate at full power on all control settings.

1. Disconnect power from cooktop.

2. Connect voltmeter test lead to H2 and L2 terminals.

3. Connect appliance to power source.

4. Set control to MED. Meter should indicate 240 VAC volts. After 10 to 15 seconds, contacts should cycle open and indicate 0 VAC.

Infinite Switch Surface Controls

Power Disconnected

All controls may be checked for continuity using the schematic diagrams in this manual. When checking continuity of suspected control contacts, disconnect terminals to avoid false readings through other components.

The most common type of failures encountered with an infinite switch are given in subsequent paragraphs. Replace failed surface control.

The bimetal heater burns open which causes the cycling contacts to remain closed. The heating element would be on full power at all control settings.

1. Disconnect power from cooktop. Disconnect wire terminals from switch terminals H1 and H2.

2. Connect ohmmeter test leads to H1 and H2 terminals. The meter indicates no continuity if heater is open. The heater resistance should be approximately 15 KΩ.

The internal switching may fail causing the element or indicator light to be on constantly or not at all.

1. Disconnect power from cooktop.

2. Disconnect wire terminals from all switch terminals.

3. Test the small halogen ring by connecting ohmmeter to L2 and H2. Set control to any setting. Meter should indicate continuity. Turn control OFF. Meter should indicate no continuity.

4. Test the large halogen by connecting ohmmeter leads to L1 and H2. Turn control to OFF. Meter should indicate no continuity.

Functional Test

1. Apply power to cooktop. The halogen element should cycle according to the position of the switch as listed:

Position % of “ON” time

1 10% 2 20% 3 30% 4 40% 5 50% 6 60% 7 70% 8 80% 9 90%

10 100%

Approximate only, time varies between units.

2. After cooktop cycles for one minute, take ON/OFF readings over a five minute period to determine whether the switch is cycling properly. If the switch is not cycling properly with proper voltage applied, replace the switch.

NOTE:

If the switch is not supplied with proper voltage (240 VAC), the cycling time will be affected. With less than 240 VAC, the cycling time will be longer. With more than 240 VAC, the cycling times will be shorter.

Troubleshooting Procedures

Multi−Position Switch

Continuity Test

1. Remove all wires connected to the control.

2. Turn control to OFF. Check for continuity between each contact (1−1a, 2−2a, 3−3a, ect.) except contacts 7−7a. If continuity is found between any contacts, the switch has failed and must be replaced.

3. There is a diode across contacts 7−7a. With the control turned to OFF, check continuity across this contact. Ohmmeter must be set at 10 KΩ setting to check diode measurement. There should be no continuity one direction and continuity the other direction. If this indication is not obtained, switch has failed and must be replaced.

4. Use the matrix above to determine if the switch is closing the proper contacts at a particular setting. If switch does not match the matrix the switch has failed and must be replaced.

5. The switch thermostat is between terminals 5 and 1a, Replace the switch if an open exists between these terminals.

NOTE:

The halogen element being controlled by the multi−position switch will vary in intensity and not cycle on and off unless the limiter switch opens.
