generating compartments, check the magnetron, waveguide or transmission line, and cavity for proper alignment, integrity and connections.

d) Any defective or misadjusted components in the interlock, monitor, door seal, and micro-

wave generation and transmission systems shall be repaired, replaced, or adjusted by procedures described in service manual before the oven is released to the owner.

e) A microwave leakage check to verify compliance with the Federal Performance Standard

should be performed on each oven prior to release to the owner.

f) Do not attempt to operate the oven if the door glass is broken.

WARNING

ELECTRICAL REQUIREMENTS

Electrical Shock Hazard

Plug into a grounded 3 prong outlet.

Do not remove ground prong.

Do not use an adapter.

Do not use an extension cord.

Failure to follow these instructions can result in death, fire, or electrical shock.

Observe all governing codes and ordinances.

Required:

A 120 Volt, 60 Hz, AC only, 15- or 20-amp • fused electrical supply (or circuit breaker).

Recommended:

GROUNDING INSTRUCTIONS

For all cord connected appliances:•

The microwave oven must be grounded.

In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. The microwave oven is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.

WARNING: Improper use of the ground-

ing plug can result in a risk of electric shock. Consult a qualified electrician or serviceman if the grounding instructions are not completely understood, or if doubt exists as to whether the microwave oven is properly grounded.

Do not use an extension cord. If the

power supply cord is too short, have a qualified electrician or serviceman install an outlet near the microwave oven.

A time-delay fuse or circuit breaker is • recommended.

A separate circuit serving only this micro-• wave oven.

ROTATE BLOWER MOTOR

The microwave oven is set for recirculation installation. For wall or roof venting, changes must be made to the venting system.

NOTE: Skip this section if you are using recirculation installation. Keep the damper assembly in case the venting method is changed, or the microwave oven is reinstalled in another location where wall or roof venting may be used.

Wall Venting Installation Only

1. Remove screw attaching damper plate to top of microwave oven exterior. Slide damper plate back and lift up.

5. Rotate blower motor end over end.

6. Rotate blower motor so that exhaust ports face the back of microwave oven, and lower blower motor back into the microwave oven.

2. Keep damper plate and screw together and set aside.

3. Remove two screws attaching blower motor to back of microwave oven.

4. Lift blower motor out of microwave oven.

7. Reattach blower motor to back of microwave oven with 2 screws removed in Step 3.

8. Reattach damper plate. Make sure tabs at top and back of damper plate are inserted fully into their respective slots in the microwave oven.

WARNING

1. Repeat Step 1 from “Wall Venting Installation Only.”

2. Repeat Step 2 from “Wall Venting Installation Only.”

3. Repeat Step 3 from “Wall Venting Installation Only.”

4. Repeat Step 4 from “Wall Venting Installation Only.”

5. Rotate the blower motor so the exhaust ports face the top of the microwave oven and the flat sides of the blower motor face the back of the microwave oven. Lower the blower motor back into the microwave oven.

7. Reattach damper plate. Make sure tabs at top and back of damper plate are inserted fully into their respective slots in the microwave oven.

8. Secure damper plate with screw.

INSTALL THE MICROWAVE OVEN

IMPORTANT: If blower motor is not posi-

tioned with flat sides facing the back of the microwave oven (as shown), performance will be poor.

6. Reattach blower motor to back of microwave oven with 2 screws removed in Step 3 of “Wall Venting Installation Only.” Securely tighten screws.

NOTE: If blower motor is not correctly oriented, the 2 screws removed in Step 3 cannot be reattached to the microwave oven.

Excessive Weight Hazard

Use two or more people to move and install microwave oven.

Failure to do so can result in back or other injury.

IMPORTANT: The control side of the

microwave oven is the heavy side. Handle the microwave oven gently.

1. Place a washer on each 1/4-20 x 3˝ bolt and place inside upper cabinet near the 3/8˝ (10 mm) holes.

2. Make sure the microwave oven door is closed and taped shut.

NOTE: If venting through the wall, make sure the damper assembly fits easily into the vent in the wall cutout.

6. Push the microwave oven against mounting plate and hold in place.

NOTE: If microwave oven does not need to be adjusted, skip steps 7-9.

3. Using 2 or more people, lift microwave oven and hang it on support tabs at the bottom of mounting plate.

NOTE: To avoid damage to the microwave oven, do not grip or use the door or door handle while the microwave oven is being handled.

4. With front of microwave oven still tilted, thread power supply cord through the power supply cord hole in the bottom of the upper cabinet.

7. If adjustment is required, rotate the microwave oven downward. Using 2 or more people, lift microwave oven off of mounting plate, and set aside on a protected surface.

8. Loosen mounting plate screws. Adjust mounting plate and retighten screws.

9. Repeat steps 3-6.

10. With the microwave oven centered, and with at least one person holding it in place, insert bolts through upper cabinet into microwave oven. Tighten bolts until there is no gap between upper cabinet and microwave oven.

NOTES:

Some upper cabinets may require bolts • longer or shorter than 3˝ (7.6 cm). Longer or shorter bolts are available at most hardware stores.

Overtightening bolts may warp the top • of the microwave oven. To avoid warping, wood filler blocks may be added. The blocks must be the same thickness as the space between the upper cabinet bottom and the microwave oven.

When the microwave oven is in use, the display shows cooking power, quantities, weights and/or prompts. When the microwave oven is not in use, the display shows the time of day or Timer countdown.

Number Codes

The microwave oven is preset with shortcut number codes. A number code includes one or more of the following: cooking power, cook time and food quantity or weight. See the charts in the “Cooking” and/or “Reheating” sections for additional information.

Start/Add 30 Seconds

The START control shares function with the Add 30 Seconds feature. The START pad will start any function. If not touched within 5 seconds after touching a pad, “START?” will appear on the display as a reminder. If not touched within 5 minutes after touching a pad, the display will return to the time of day mode and the programmed function will be canceled.

If cooking is interrupted, touching the START will resume the preset cycle.

DISPLAY

When power is rst supplied to the microwave

oven, a “:” will blink in the display. Touch (Cancel) to stop the blinking. If the “:” blinks in the display at any other time, a power failure has occurred. Touch (Cancel) and reset the clock if needed.

If “RETRY” blinks in the display for 1 second, an invalid value has been entered. Retry your entry.

The ADD 30 SEC. control starts the oven at 100% power for 30 seconds, and adds 30 seconds of cook time with each additional touch of the control. Once cooking begins, cook power or cook time may be changed manually by touching the appropriate display area and entering the new setting.

Easy Minute Feature

The numerical pads 1-5 share function with the Easy Minute controls. When one of these controls is touched (while no function is operating), the oven will begin cooking at high power for 1-5 minutes, depending on which pad is touched. After cooking begins, the Easy Minute controls return to their normal numerical pad function.

Cancel

The CANCEL pad stops most functions except for the Timer, Child Lock and Demo Mode.

The microwave oven will also turn off when the door is opened. Close the door and touch START control to resume the cycle. A sensor

3-2

cooking cycle may not be resumed if interrupted by opening the door.
