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.With the support tabs facing forward (see illustrations in “Possible Wall Stud Configurations” in “Locate Wall Stud(s)” section), align the mounting plate center markers 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.
NOTE: 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.

3.Holding the mounting plate in place, mark both bottom corner holes.
4.Find the wall stud centerline(s) marked in Step 2 of “Locate Wall Stud(s),” and mark at least 1, preferably 2, hole(s) through the mounting plate, closest to the centerline(s). See figures 1, 2 and/or 3 in “Possible Wall Stud Configurations” in “Locate Wall Stud(s)” section. The blackened holes in the shaded areas are ideal hole locations.
5.Set mounting plate aside.

Centerline | Upper cabinet bottom |
| ³⁄₈" (1 cm) |
4" (10.2 cm) |

6" (15.2 cm) | 6" (15.2 cm) |
6.Mark the centerline 3/8" (1 cm) down from the bottom edge of the upper cabinet.
7.Using measuring tape, measure out 6" (15.2 cm) on both sides of the centerline, and mark.
8.Measure down 4" (10.2 cm) from the mark made in Step 6, and mark.
9.Using a straightedge, draw the 2 horizontal, level lines through the marks made in steps 6 and 8.
10.Draw the 2 vertical, plumb lines down from the marks made in Step 7 to complete the 12" x 4" (30.5 x 10.2 cm) rectangle. This is the venting cutout area.
11.Cut a 3/4" (19 mm) hole in one corner of the cutout area.
12.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 bottom corner holes. If the holes are not over wall studs, use two
3 installation configurations.
Installation for No Wall Studs at Corner Holes (Figures 1 & 2)
1.Drill 3/4" (19 mm) holes through the wall at both bottom corner 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 4 of “Mark Rear Wall.” Refer to figures 1 and 2 in “Possible Wall Stud Configurations” in “Locate Wall Stud(s)” section.
Installation for Wall Stud at One Corner Hole (Figure 3)
1.Drill a 3/16" (5 mm) hole into the wall stud at the corner 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 4 of “Mark Rear Wall.” Refer to Figure 3 in “Possible Wall Stud Configurations” in “Locate Wall Stud(s)” section.
3.Drill a 3/4" (19 mm) hole through the wall at the other corner hole.
Installation for Wall Studs at Both Corner Holes (Figure 4)
1.Drill 3/16" (5 mm) holes into the studs at the corner holes marked in Step 3 of “Mark Rear Wall.”
