Lift the microwave, tilt it forward, and hook slots at

back bottom edge onto four lower tabs of the

mounting plate.

Rotate the front of the oven up against cabinet bottom.

Insert a self-aligning screw (item A) through top center

cabinet hole. Temporarily secure the oven by turning

the screw at least two full turns after the threads have

engaged.

Insert the two remaining self-aligning screws through

outer top cabinet holes. Turn two full turns on each

screw.

Tighten center screw completely.

Tighten the outer two screws completely to the top of

the microwave oven.

Note: While tightening screws, hold the microwave

oven in place against the wall and the top cabinet.

Install grease filters by sliding them into the side slots,

then pushing up and toward oven 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:
