Location Requirements
Check the opening where the microwave oven will be installed.
The location must provide:
■ Minimum installation dimensions. See “Installation
Dimensions” illustration.
■ Minimum one 2" x 4" (50.8 x 101.6 mm) wood wall stud and
minimum 3/8" (10 mm) thickness drywall or plaster/lath within

NOTES:
■ If installing the microwave oven near a left sidewall, make sure
there is at least 6" (15.2 cm) of clearance between the wall and
the microwave oven, so that the door can open fully.
■ Some cabinet and building materials are not designed to
withstand the heat produced by the microwave oven for
cooking. Check with your builder or cabinet supplier to make
sure that the materials used will not discolor, delaminate or
sustain other damages.

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.
WARNING
GROUNDING INSTRUCTIONS
SAVE THESE 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 grounding 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.
NOTE: The grounded 3 prong outlet must be inside the upper
cabinet. See “Electrical Requirements” section.
Electrical Requirements
Observe all governing codes and ordinances.
Required:
■ A 120 volt, 60 Hz, AC only, 15- or 20-amp electrical supply
with a fuse or circuit breaker.
Recommended:
■ A time-delay fuse or time-delay circuit breaker.
■ A separate circuit serving only this microwave oven.
A. 2" x 4" wall stud

Depending on your model, the mounting plate may be in the foam
packaging, or it may be attached to the back of the microwave
oven.
NOTE: To avoid possible damage to the work surface, cover the

cavity.
2. If the mounting plate is attached to the back of the microwave
oven, remove it and set it aside.

swing open while the microwave oven is being handled.
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.
