Location Requirements

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″ (51 x 102 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.
  NOTE: 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 fit 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″ (76 mm) 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 on the Owner Manual on the product.

NOTE: If no wall studs exist within the cabinet opening, do not install the microwave oven. See illustrations in “Possible Wall Stud Configurations.”

1. Using a stud finer, locate the edges of the wall stud(s) within the opening.
2. Mark the center of each stud, and draw a plumb line down each stud center. See illustrations in “Possible Wall Stud Configurations.”

1.  Using measuring tape, and clearly mark the vertical centerline
   of the opening. Make sure it is align with the vertical wall
   centerline.
   
   The upper cabinet template is fit for depth of 13″ (35 cm) to 16″ (40.6 cm) cabinet installation, but need some adjustment for different depth. See the following steps.

2. Using measuring tape, measure the depth of the cabinet. The upper cabinet template is for variable cabinet depth use, find a dimension of your cabinet in below table.
   | Flush Depth (cabinet + door)| Stand-out Depth (cabinet + door)
   ---|---|---
   L| 133 /4″ to 14″ (35 cm to 35.6 cm| 13″ to 133 /4″ (33 cm to 35 cm)

NOTE : There are two install methods, one is flush to the cabinet door, another one is stand-out from the cabinet door. Find the dimension of your cabinet in above table, the dimensions in the left colomn are flush to the cabinet door, the dimensions in the right colomn are stand-out from the cabinet door.
Flush to the cabinet door, front allignment installation, follow below steps:

3. For example, the cabinet depth is 14″ (35.6 cm), you need to cut or fold the grey portion of the upper cabinet template.
   

4.  Place and tape the upper cabinet template against the bottom of the upper cabinet.
   NOTES :
   • Make sure the front edge of the upper cabinet template align with the front edge of upper cabinet.
   • Make sure the center marks on the upper cabinet template align with the upper cabinet centerline which draw in step 1.

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. See “Find the Wall Stud(s)” section for find the wall studs.

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

2. Tape the Wall template in place. Align the center mark on the wall template over the vertical centerline draw in step 1. Make sure the wall template is level, and that the top of the wall template is butted up against the bottom edge of the upper cabinet

Drill Holes in Upper Cabinet

1.  Using a 3/4″ (1.9 cm) hole saw, cut out the power cord hole (A), which is “G” on the upper cabinet template.

2.  Drill two mounting nut holes (B), which are 3/8″ (10 mm) holes at points “D” and “E” on the upper cabinet template. These are for two 1/4-20 x 3″ bolts and washers used to secure the microwave oven to the upper cabinet.

4.  Using a keyhole saw, cut out the rectangular area.
   NOTE : If the front edge of the upper cabinet is lower than the back edge, lower the wall template so that its top is level with the front edge of the cabinet.
   

Drill Holes in Rear Wall

In addition to being installed on at least one 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 one end hole is over a wall stud, use one 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 two lag screws. Following are four installation configurations. Installation for No Wall Studs at End Holes (See figure 1 in the “Locate Wall Studs” section)

Attach Bump Out Mounting Plate to Wall

Attach Bump Out Mounting Plate to Wall NOTE: Secure the mounting plate to the wall at both end holes drilled into the wall studs and/or drywall using either 3/16-24 x 3″ round-head bolts and toggle nuts and 1/4 x 2″ lag screws. Refer to illustrations in “Possible Wall Stud Configurations” in the “Locate Wall Stud(s)” section. Note: If the depth of cabinet is slightly larger than 16″, it may be necessary to use a number of the provided spacers, between the mounting plate and the wall, to achieve a more ‘Flush’ appearance. Stick spacer(s) before position mounting plate on the wall.
