LOCATION REQUIREMENTS
IMPORTANT: Check the opening where the microwave oven will be installed.
The location must provide:
•The unit must be mounted to both a top cabinet and a wall. It cannot be
installed in cabinet arrangements such as an island or a peninsula.
•Minimum installation dimensions. See the "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 cabinet opening.
•Support for weight of 150 lbs (68 kg) which includes microwave oven and
items placed inside the microwave oven and upper cabinet.
•Grounded electrical outlet inside upper cabinet. See the "Electrical
Requirements" section.
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.
SPECIAL REQUIREMENTS
For Wall Venting Installation Only:
•Cutout must be free of any obstructions so that the vent fits properly and
the damper blade opens freely and fully.
For Roof Venting Installation Only:
•If you are using a rectangular-to-round transition piece, the 3" (7.6 cm)
clearance needs to exist above the microwave oven so that the damper
blade can open freely and fully.

ELECTRICAL REQUIREMENTS
WARNING
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 following these instructions can result in death, fire, or electrical
shock.
Observe all governing codes and ordinances.
Product rating:
Required:
•A 120 V, 60 Hz, AC only, 15 or 20 A 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.
This product must be connected to a separate and dedicated supply circuit of
the proper voltage and frequency. Wire size must conform to the
requirements of the National Electrical Code or the prevailing local code for
this kilowatt rating.
The power supply cord and plug should be brought to a separate and
dedicated 15- to 20- ampere branch circuit single grounded outlet. The outlet
box should be located in the cabinet above the microwave oven.
The outlet box and supply circuit should be installed by a qualified electrician
and conform to the National Electrical Code or the prevailing local code.
•A 120 V AC, 60 Hz, 15 A, 1550 W.

11
The installer must perform a ground continuity check on the power outlet box
before beginning the installation to ensure that the outlet box is properly
grounded. A qualified electrician should be employed to correct any
deficiencies.
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.
•Where a standard two-prong wall receptacle is encountered, have it
replaced with a properly grounded three-prong wall receptacle by a
qualified electrician.
WARNING:
•Do not, under any circumstances, cut, deform, or remove any of the
prongs from the power cord.
•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.

•If top cabinets are deeper than 13.8" (35 cm), the unit must be spaced out
from the wall using adequate materials supporting 150 lbs to allow top
vent airflow in the front. These materials are not provided.
•Before positioning the Rear Wall Mounting Template, use a level to make
sure the cabinet bottom is level.
