Materials Needed

Standard ﬁttings for wall or roof venting. See the “Venting Design Speciﬁcations” section.

Location Requirements

IMPORTANT: Check the opening where the microwave oven will be installed. The location must provide:

■ 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. See “Rectangular to Round Transition” illustration in the “Venting Design Speciﬁcations” section.

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 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 electrical supply

with a fuse or circuit breaker

Recommended:

■ A time-delay fuse or time-delay circuit breaker

A. 2" x 4" wall stud B. Grounded 3 prong outlet

*24” (61 cm) is typical for 60” (152.4 cm) installation height. Exact dimensions may vary depending on type of range/ cooktop below.

Product Dimensions

*Overall depth of product will vary slightly depending on door design.

■ A separate circuit serving only this microwave oven

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 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.

The microwave oven must be installed on a minimum of 1 wall stud, preferably 2, using a minimum of 1 lag screw, preferably 2.

1. Using measuring tape, ﬁnd and clearly mark the vertical

centerline of the opening.

2. Align the center markers on the mounting plate to the

centerline on the wall, making sure it is level, and that the top of the mounting plate is butted up against the bottom edge of the upper cabinet.

NOTES:

■ If the front edge of the upper cabinet is lower than the

back edge, lower the mounting plate so that its top is level with the front edge of the cabinet.

■ If the mounting template is damaged or unusable,

measure and mark the wall with the dimensions described in Step 4.

■ The end holes must be 8.78" (22.3 cm) from the bottom edge

of the upper cabinet and must be on a level line with each other. They must each be 14¹⁄8" (35.9 cm) from the centerline.

5. With the support tabs facing forward (see illustrations in

the “Locate Wall Stud(s)” section), align the mounting plate center markers to the centerline on the wall, making sure its bottom edge is aligned to the horizontal line drawn in Step 3 and that the end holes are properly marked. Make sure the mounting plate is level.

6. Holding the mounting plate in place, ﬁnd the wall stud

centerline(s) drawn in Step 2 of “Locate Wall Stud(s)” and mark at least 1, preferably 2 hole(s) through the mounting plate, closest to the wall stud centerline(s). See ﬁgures 1, 2, and/or 3 in “Possible Wall Stud Conﬁgurations” in the “Locate Wall Stud(s)” section. The blackened holes in the shaded areas are ideal hole locations.
