Important Safety Instructions

Recognize this symbol as a SAFETY

message

Caution

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

Caution

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.

Caution

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.

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.

Caution

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

Caution

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.
