of injury, and tell you what can happen if the instructions are not followed.
1-1
PRECAUTIONS TO BE OBSERVED BEFORE AND
DURING SERVICING TO AVOID POSSIBLE EXPOSURE
TO EXCESSIVE MICROWAVE ENERGY
a) Do not operate or allow the oven to be operated with the door open.
b) Make the following safety checks on all ovens to be serviced before activating the
magnetron or other microwave source, and make repairs as necessary:
1. Interlock Operation
2. Proper Door Closing
3. Seal and Sealing Surfaces (Arcing, Wear and Other Damage)
4. Damage to or Loosening of Hinges and Latches
5. Evidence of Dropping or Abuse
Before turning on microwave power for any service test or inspection within the microwave
c)
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.
A microwave leakage check to verify compliance with the Federal Performance Standard
e)
should be performed on each oven prior to release to the owner.
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 microwave oven.

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.

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.
Reattach blower motor to back of mi-
6.
crowave 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.
Place a washer on each 1/4-20 x 3˝ bolt
1.
and place inside upper cabinet near the
3/8˝ (10 mm) holes.
Make sure the microwave oven door is

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.
5. Rotate the microwave oven up toward
upper cabinet.
NOTE: If venting through the wall, make sure
the damper assembly fits easily into the vent
in the wall cutout.
Push the microwave oven against mount-
6.
ing plate and hold in place.
NOTE: If microwave oven does not need to
be adjusted, skip steps 7-9.
If adjustment is required, rotate the
7.
microwave oven downward. Using 2 or
more people, lift microwave oven off of
mounting plate, and set aside on a protected surface.
Loosen mounting plate screws. Adjust
8.
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:
•
With front of microwave oven still tilted,
4.
thread power supply cord through the
power supply cord hole in the bottom of
the upper cabinet.
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.
