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.

Installation Dimensions

NOTE: The grounded 3 prong outlet must be inside the upper cabinet. See the “Electrical Requirements” 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, 15or 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

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.

Mark Rear Wall

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.

A.Centerline

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.

A.Rear wall

B.Mounting Template

C.Top of mounting template must

align with front edge of cabinet D. Front edge of upper cabinet

3.Holding the mounting template in place, mark both holes in the lower corners and draw a horizontal line across the

bottom edge of the mounting template. These represent the mounting plate’s end holes and bottom edge.

4.Remove the mounting template and check the markings:

■■ The bottom edge line must be 10.47" (26.6 cm) from the bottom of the upper cabinet and must be level.

■■ 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.

7.Set the mounting plate aside.

8.Mark the centerline 3/8" (1 cm) down from the bottom edge of the upper cabinet.

9.Using measuring tape, measure out 6" (15.2 cm) on both sides of the centerline, and mark.

10.Measure down 4" (10.2 cm) from the mark made in step 8 and mark.

11.Using a straightedge, draw the 2 horizontal, level lines through the marks made in steps 8 and 10.

12.Draw the 2 vertical plumb lines down from the marks made in step 9 to complete the 12" x 4" (30.5 x 10.2 cm) rectangle. This is the venting cutout area.

13.Cut a ³⁄4" (19 mm) hole in one corner of the cutout area.

14.Using a keyhole saw, cut out the venting cutout area.

Drill Holes in Rear Wall

In addition to being installed on at least 1 wall stud, the mounting plate must attach to the wall at both end holes. If the end holes are not over wall studs, use two 3/16-24 x 3" round head bolts with toggle nuts; if 1 end hole is over a wall stud, use 1 lag screw and one 3/16-24 x 3" round-head bolt with toggle nut; or if both end holes are over wall studs, use 2 lag screws. Following are 3 installation configurations.

Installation for No Wall Studs at End Holes (Figures 1 and 2)

1.Drill 5/8" (16 mm) holes through the wall at both end holes marked in Step 3 of “Mark Rear Wall.”

2.Drill 3/16" (5 mm) hole(s) into the wall stud(s) at the hole(s) marked in Step 6 of “Mark Rear Wall.” Refer to figures 1 and 2 in “Possible Wall Stud Configurations” in the “Locate Wall Stud(s)” section.

Installation for Wall Stud at One End Hole (Figure 3)

1.Drill a 3/16" (5 mm) hole into the wall stud at the end hole marked in Step 3 of “Mark Rear Wall.”

2.If installing on a second wall stud, drill a 3/16" (5 mm) hole into the wall stud at the other hole marked in Step 6 of “Mark Rear Wall.” Refer to Figure 3 in “Possible Wall Stud Configurations” in the “Locate Wall Stud(s)” section.

3.Drill a 5/8" (16 mm) hole through the wall at the other end hole.

Installation for Wall Studs at Both End Holes (Figure 4)
