Measure And Track/Tape Up The Templates

1. Using a plumb line and measuring tape, find and mark the vertical center line on the back wall, as in Figure 24.
2. Find and mark one or two points where the studs are on the wall. Then measure and mark the stud locations. If you cannot find any wall stud, consult a local building contractor.

CAUTION

DO NOT ATTEMPT TO INSTALL THE MICRO-WAVE OVEN IF YOU CANNOT FIND A WALL STUD.

3. Line up the plumb line on the wall with the center line on the mounting plate.
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 is at least 30 inches. See Figure 24.

4. Center mounting plate in operating by lining up the plumb line on wall with centerline on mounting plate. Make sure the minimum width is 30 inches and that the top of the mounting plate is located a minimum of 30 inches above the cooking surface. See Figure 25.
NOTE : If the cabinets are not plumb, adjust the mounting plate to the cabinets. If the front edge of the cabinet is lower than the back edge, adjust the mounting plate 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 the template so it fits inside the recessed area. Align the centerline of the upper cabinet template with the centerline of the mounting plate, then securely tape or tack the upper cabinet template in place. See Figure 25.

WARNING

To avoid risk of personal injury, electrical shock or death:

Note where electrical outlets and electrical wires are before you drill into the wall.
Locate and disconnect power to any electrical circuits that could be affected by installing this oven.

To avoid risk of personal injury, electrical shock or death, cover the edge of the power supply cord hole with the power supply cord bushing.

Drill The Holes In The Wall And Upper Cabinet.

1. Drill holes on the circles. If there is a stud, drill a 3/16″ hole for lag screws. If there is no stud, drill a 3/4″ hole for toggle screws. Make sure to use at least 1 lag screw in a stud, and 4 toggle screws in the drywall or the plaster.
2. Drill a 1/2” hole at points D,E and J on the upper cabinet template.

NOTE: If the bottom of the upper cabinet is recessed 3/4″ or more, you will need 2″x 2″ filler blocks (not included) to provide additional support for the bolts. See Figure 26.

Mark the center of each filler block and drill a 1/2″ 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 27.

3. Cut or drill a 1 3/4″ 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.

4. Cut out the venting areas (with the saber saw):

Roof-Vented: cut out the shaded area marked L on the upper cabinet template.
Wall-Vented: Tape the rear wall template to the rear wall, lining up with the holes previously drilled for holes A and B in the plate. Cut out the shaded area marked F on the REAR WALL TEMPLATE.
Room-Vented: go to STEP 5, INSTALL THE MOUNTING PLATE, located on page 14.

5. Complete whichever venting system you have chosen. Use caulking compound to seal the exterior wall or roof opening around the wall cap or roof cap.

STEP 5: INSTALL THE MOUNTING PLATE

The Oven Must Be Connected To At Least One Wall Stud.

1. Draw a vertical line on the wall at the center of the 30 wide space. Use the mounting plate as the template for the rear wall. Place the mounting plate on the wall, making sure that the tabs are against the bottom of the cabinet. Line up the notch and center line on the mounting plate to the center line on the wall.
2. While holding the mounting plate with one hand, draw circles on the wall at holes A, B, C and D. Four holes must be used for mounting. If the holes are not used, the installation will not be secure. Installer must use these holes for proper installation. Use toggle bolts through these holes unless one of them lines up with a stud. Use a wood screw for studs.

NOTE: Draw a fifth circle inside area E, through one of the bottom holes to match the location of a stud. For wall-vented: The oven requires a rear wall cutout opening for the rear wall duct and the exhaust adapter must be attached to the mounting plate. See the next page on how to prepare the rear wall cutout opening and the exhaust adapter/mounting plate for wall-vented.

3. Drill holes on the circles. If there is a stud, drill a 3/16 hole for lag screws. If there is no stud, drill a 5/8 hole for toggle bolts. Make sure to use at least 1 lag screw in a stud, and 4 toggle bolts in the drywall or the plaster.
4. Attach the plate to the wall. To use spring toggle head bolts: Remove the toggle wings from the bolts. Insert the bolts into the mounting plate and replace the spring toggle head to 3/4 past the bolt ends. Insert the spring toggle head into the holes in the wall to mount the plate. You may pull forward on the plate to help in tightening the toggle bolts. Tighten all bolts.

For Wall-Vented

Make the box cutout for the rear wall duct.

– 1 piece mounting plate:
Using a pencil, put dots through slots F and G, and through holes H and I. Remove the mounting plate and draw lines extending through the points. This will give the location and size of the box cutout for the rear wall duct. (Figure 30)
– 3 pieces mounting plate:
Use the wall template to determine the location and size of the box cutout for the rear wall duct.

Attach the exhaust adapter to the rear mounting plate (back plate) wall side. Push in securely until it is past the top locking tabs and in the lower locking tabs. Take care to assure the damper hinge is installed so that it is at the top and that the damper swings freely.
Carefully guide the exhaust adapter, now attached to the mounting plate, into the house duct. Before using the screws to attach the plate to the wall. This will assure proper alignment for installation.
Return to step 5, item 3 to continue. After completing the installation of the mounting plate, again check the rear damper for free movement to assure it will operate properly.
