Mounting the appliance

Notes

• If the bottom of the upper cabinet is recessed or has front overhang, you will need to prepare 2″ x 2″ (51 mm x 51 mm – depth equivalent to cabinet recess or overhang) filler blocks to provide additional support for the bolts:
  • mark the center of each filler block and drill a 3 \8″ (10 mm) diameter hole
  • align filler blocks over the three openings on top of the appliance and attach with masking tape
• Use at least two people to install the appliance. Do not grip or use handle during the installation.
• When mounting the appliance, thread power cord through hole in bottom of top cabinet. Keep the cord tight and do not pinch it, especially when mounting flush to bottom of cabinet. Do not pull the cord to lift the appliance.

1. Lift the appliance, tilt it forward, and hook slots at back bottom edge onto four lower tabs of the mounting plate.

2. Rotate the front of the appliance up against cabinet bottom.

3. Insert a self-aligning screw (item A) through top center cabinet hole. Temporarily secure the appliance by turning the screw at least two full turns after the threads have engaged.

4. Insert the two remaining self-aligning screws through outer top cabinet holes. Turn two full turns on each screw.

5. Tighten center screw completely.

6. Tighten the outer two screws completely to the top of the appliance.
   Note : While tightening screws, hold the appliance in place against the wall and the top cabinet.

7. Install grease filters by sliding them into the side slots, then pushing up and toward the appliance to lock (image shows bottom view of appliance).

Hood exhaust
When venting exhaust to the outside, hood exhaust ducts will be required. Read the following carefully.
Note: It is important that venting be installed using the most direct route and with as few elbows as possible. This ensures clear venting of exhaust and helps prevent blockages. Also, make sure dampers swing freely and nothing is blocking the ducts.
The hood exhaust has been designed to mate with a standard 3¼” x 10″ (82 x 254 mm) rectangular duct. If a round duct is required, a rectangular-to-round transition adaptor must be used. Do not use less than a 6″
(152 mm) diameter duct.
For satisfactory air movement, the total duct length of 3¼” x 10″ (82 x 254 mm) rectangular or 6″ (152 mm) diameter round should not exceed 120 equivalent feet (36.5 m).
Elbows, transitions, wall and roof caps etc. cause additional resistance to airflow and are equivalent to a section of straight duct which is longer than their actual physical size. When calculating the total duct length, add the equivalent lengths of all transitions and adaptors plus the length of all straight duct sections. The chart below shows you how to calculate total equivalent ductwork length using the approximate feet of equivalent length of some typical ducts:

• If a rectangular-to-round transition adapter is used, first make sure the damper hinge of the appliance swings freely. If necessary, cut the damper to fit, using the tin snips, in order to allow free movement.
  Equivalent lengths of duct pieces are based on actual tests and reflect requirements for good venting performance with any vent hood.

Testing Operation

1. Turn on power at the breaker.

2. Test the microwave:
   Place a cup of water into the appliance cavity. Follow the instructions in the Use and Care Manual on how to heat a beverage.
   NOTICE : Never run the microwave unless there is food in the appliance cavity.

3. Verify that the appliance cavity light comes on and the water is heated.

4. If any of the tests do not result as explained above, contact Service for assistance. Otherwise, the installation is complete at this time.
