With the support tabs of the mounting plate facing forward, insert a 3/16-24 x 3" (7.6 cm) round-head bolt through the end hole that fits over the 5/8" (16 mm) hole drilled in Step 3 of "Installation for Wall Stud at One End Hole" in the "Drill Holes in Rear Wall" section. 2. Start a toggle nut on the bolt from the back of the mounting plate. Leave enough space for the toggle nut to go through the wall and to open. 3. Position mounting plate on the wall. 4. Push the bolt with toggle nut through the drywall, and finger tighten the bolt to make sure toggle nut has opened against drywall. 5. Insert a lag screw into the remaining end hole. 6.

Remove all contents from upper cabinet. 3. Place Upper Cabinet Template against the bottom of the upper cabinet, and attach with tape or thumbtacks. Make sure the template centerline aligns with the vertical centerline on the rear wall. The "rear wall" arrows must be against the rear wall so that the holes cut into the upper cabinet align with the holes in the top of the microwave oven. NOTES: ■■ If the upper cabinet has a frame around it, trim the template edges so that it fits inside the frame, against the upper cabinet bottom. The template has trim lines to use as guides. ■■ If the wall behind the microwave oven (as installed) has a partial wall covering (for example, tile backsplash), be sure the "Rear Wall" arrows align to the thickest part of the rear wall (for example, the thickness of the tiles rather than the drywall). 4. Make sure the 10" (25.4 cm) dimension from the rear wall to points "D" and "E" on the template is maintained. Upper-cabinet template D 10" (25.4 cm) F E 10" G (25.4 cm) 5. Cut the 11⁄2" (3.8 cm) diameter hole at the circular shaded area "G" on the template. This hole is for the power supply cord. NOTE: If upper cabinet is metal, the supply cord bushing needs to be installed around the supply cord hole as shown. B A A. Metal cabinet B. Power supply cord bushing 6. Drill 3/8" (10 mm) holes at points "D" and "E" on the template. These are for two 1/4-20 x 3" (7.6 cm) bolts and washers used to secure the microwave oven to the upper cabinet. For Roof Venting Installation Only 7. Cut 3/4" (1.9 cm) hole at one corner of the shaded rectangular area "F" on Upper Cabinet Template. 8. Using a keyhole saw, cut out the rectangular area. 9
