Important Safety Instructions

Recognize this symbol as a SAFETY message


To avoid electrical shock hazard remove house fuse or open circuit breaker before installing microwave oven.

Mounting Space

This over-the-range microwave oven requires wall mounting space, as shown below.

Minimum of 30 inches between cabinets is required for installation. If space between cabinets is greater

than 30 inches, filler panel kit may be used to fill in gap between microwave oven and cabinets. Contact dealer to purchase filler panel kit.


To avoid personal injury, mounting surface must be capable of supporting microwave oven (65 lbs.) and oven loads (up to 50 lbs.) for a total weight of 115 lbs.


To avoid personal injury, do not install microwave oven in island or peninsula. This microwave oven must be mounted to both top cabinet and wall.


To avoid personal injury, protect hands and arms. Microwave oven may have sharp edges.


To reduce risk of fire, use only metal duct.

Electrical Requirements

This product requires three-prong grounded outlet. Verify outlet box is properly grounded. If box is not properly grounded or does not meet electrical requirements, contact qualified electrician. Oven rating is 120 volts AC, 60 Hertz, 13.5 amps, and 1.45 kilowatts. Oven must be connected to circuit of proper voltage and frequency. Wire size must conform to requirements of National Electric Code or prevailing local code. Power supply cord and plug should be connected to separate 15 to 20 amp. circuit, single grounded outlet. Outlet box should be located in cabinet above oven. Outlet box and supply circuit should be installed by qualified electrician and conform to National Electric Code or prevailing local code. For easier installation and personal safety, two people should install microwave oven.

Verify bottom edge of cabinet is at least 66 inches from floor and 30 inches from cooking surface.

Bottom of microwave oven should be at least 2 inches above range backsplash for easy access to change hood and range lamps.

For outside ventilation, see "Preparing Microwave Exhaust Duct" section.

Charcoal filter kit is needed for recirculating exhaust installation. Contact dealer to purchase charcoal filter kit.

When installing microwave oven beneath smooth,

flat cabinets, follow instructions on top cabinet template for power cord clearance.

Cabinets may have trim that interferes with microwave oven installation. Remove interfering trim to allow microwave oven installation and leveling.

Space must be 30 inches wide. Remove any cabinet side trim that interferes with 30 inch space, front or back.

Top cabinet trim (front, back, or both) can be left in place if there is enough clearance for proper installation. If top front trim is left in place, and there is no back trim, verify that mounting plate is positioned down far enough to keep microwave oven level. Keep space between bottom of cabinet and mounting plate equal to height of top front trim. This will ensure that microwave oven is level.

Hood Exhaust Duct

Outside ventilation requires hood exhaust duct. Use only metal duct. Read the following carefully.

Exhaust Connection: Hood exhaust has been designed to mate with standard 3 1/4 inch x 10 inch rectangular duct. If round duct is required, rectangular-to-round transition adaptor must be used. Do not use less than 6 inch diameter duct.

Rear Exhaust: If rear or horizontal exhaust is to be used, care should be taken to align exhaust with space between studs.

Maximum Duct Length: Total duct length of 3 1/4 inch x 10 inch rectangular or 6 inch diameter round duct should not exceed 140 equivalent feet for satisfactory air movement.

Elbows, Transitions, Wall and Roof Caps, Etc.

Elbows, transitions, wall and roof caps, etc., create additional resistance to airflow and are equivalent to a section of straight duct. When calculating total duct length, add equivalent lengths of all transitions and adaptors, plus length of all straight duct sections. Chart below shows approximate feet of equivalent length of some typical ducts.

Charcoal filter kit: Charcoal filter kit is needed for recirculating exhaust installation.

Filler panel kit: If space between cabinets is greater than 30 inches, filler panel kit may be used to fill in gap between microwave oven and cabinets.

* If rectangular-to-round transition adaptor is used, bottom corners of damper will have to be cut to fit, using tin snips, in order to allow free movement of damper.


Installation Instructions
