STEP 4: PREPARE THE WALL AND
UPPER CABINET FOR INSTALLATION
BEFORE YOU START
1. Remove any shipping materials and parts from inside the
microwave oveR.
2. Cover the counter top or cooktop with a thick, protective
covering to protect it from damage and dirt. See Figure
19.
NOTE: If you have a free-standing range, disconnect it,
move it onto a piece of cardboard or hardboard
and pull it away from the wall, so that you can get
closer to the upper cabinet and back wall for
easier measuring and drilling.
MEASURE AND TACK / TAPE UP THE
TEMPLATES
1. Using a plumb line and (metal) measuring tape, find and
mark the vertical center line on the back wall, as
in Figure 20.
2. Find and mark one or two points where the studs are on
the wall (Studs are normally 16 inches apart.) and then
measure and mark the stud locations within the area
marked "H" on the wall template.
If you cannot find any wall stud, consult a local building
contractor.
CAUTION
DO NOT ATTEMPT TO INSTALL THE MICROWAVE
OVEN IF YOU CANNOT FIND A WALL STUD.
A thick, protective

3. Line up the plumb line on the wall with the center line on
the wall template.
NOTE: Be sure the minimum width is 30 inches and the
distance from the top of the wall template to the
range or counter top at least 30 inches. See
Figure 4 on page 4.
4. Securely tape or tack the wall template to the wall. See
Figure 21.
NOTE: If the cabinets are not plumb, adjust the wall
template to the cabinets.
Ifthe front edge of the cabinet is lower than the
back edge, adjust the wall template to be level
with the cabinet front.
5. Measure the bottom of the upper cabinet frame. Trim the
edges "A" "B" and "C" on the upper cabinet template so
that the template will fit on the bottom of the upper
cabinet. If upper cabinet has a recessed frame, trim
template so that it fits inside the recessed area. Align the
centerline of the upper cabinet template with the
centerline of the wall template; then securely tape or tack
the upper cabinet template in place. See Figure 21.

DRILL THE HOLES IN THE WALL AND UPPER CABINET.
WARNING
BE VERY CAREFUL WHEN DRILLING HOLES INTO THE WALL.
Electrical wires could be concealed behind the wall covering
and if the drill hits them you could get an electric shock.
1. Find the points on the wall template labeled "D", "E", "F", and "G". Drill a 3/16" diameter hole at any points
that are over a wall stud. Drill a 3/4" diameter hole at any points over drywall.
2. Locate the wall stud closest to the center of the areas marked "H" and "1" on the wall template. Drill 3/16"
holes into the wall stud in each of the areas. If a wall stud is not located within these areas, drill 3/4"
diameter holes nearest to the center of the areas as possible.
If there is not a wall stud within the areas marked "H" and "1" and not behind points marked "D",
"E", "F" and "G", DO NOT install microwave oven. (Consult building inspector.)
3. Drill a 3/8" hole at points "J", "K" and "N" on the upper cabinet template.
NOTE: If the bottom of the upper cabinet is recessed 3/4" or more, you will need 2"x2" filler blocks (not
included) to provide additional support for the bolts. See Figure 22.
• Mark the center of each filler block and drill a 3/8" diameter hole at the marks.
• Align filler blocks over the two openings in the top of the microwave oven cabinet and attach to
cabinet with masking tape. See Figure 23.
4. Cut or drill a "2" diameter hole at the area marked "M",
"Power-supply-cord-hole" on the upper cabinet template. If
the upper cabinet is metal, you will need to cover the edge
of the hole with the power-supply-cord bushing (supplied)
to prevent damage to the cord from the rough metal edge.
