General information

Insure proper
ground exists
before use

IMPORTANT SAFETY INSTRUCTIONS

This product requires a three-prong grounded
outlet. The installer must perform a ground
continuity check on the power outlet box before
beginning the installation to ensure that the
outlet box is properly grounded. If not properly
grounded, or if the outlet box does not meet
electrical requirements noted (under ELECTRICAL
REQUIREMENTS), a qualified electrician should be
employed to correct any deficiencies.

CAUTION: For personal
safety, remove the
house fuse or open
the circuit breaker
before beginning the
installation to avoid
severe or fatal shock
injury.

CAUTION: For personal safety, the mounting
surface must be capable of supporting the
cabinet load in addition to the added weight
of this 69 pound product, plus additional oven
loads of up to 50 pounds or a total weight of
109 pounds.

CAUTION: For personal safety, do not install
this product in cabinetry configured as an
island or a peninsula. The microwave oven
must be mounted to BOTH a top cabinet AND
a wall.

NOTE: For easier installation and personal
safety, we recommend that two people install
this product.

IMPORTANT – PLEASE READ CAREFULLY.
FOR PERSONAL SAFETY, THIS APPLIANCE
MUST BE PROPERLY GROUNDED TO AVOID
SEVERE OR FATAL SHOCK.

The power cord of this
appliance is equipped
with a three-prong
(grounding) plug which
mates with a standard
three-prong (grounding)

Insure proper
ground exists
before use.

You should have the wall receptacle and circuit
checked by a qualified electrician to make sure
the receptacle is properly grounded.

If you have a standard two-prong wall
receptacle, it is very important to have it
replaced with a properly grounded three­prong wall receptacle, installed by a qualified
electrician.

DO NOT, UNDER ANY CIRCUMSTANCES, CUT,
DEFORM OR REMOVE ANY OF THE PRONGS
FROM THE POWER CORD. DO NOT USE WITH
AN EXTENSION CORD.

wall receptacle to
minimize the possibility
of electric shock hazard
from this appliance.

ELECTRICAL
REQUIREMENTS

Product rating is 120 volts AC, 60 Hertz, 14.5
amps and 1.7 kilowatts.This product must be
connected to a supply circuit of the proper voltage
and frequency. Wire size must conform to the
requirements of the National Electrical Code or the
prevailing local code for this kilowatt rating. The
power supply cord and plug should be brought to a
separate 15 ampere branch circuit single grounded
outlet. The outlet box should be located in the
cabinet above the microwave oven. The outlet box
and supply circuit should be installed by a qualified
electrician and conform to the National Electrical
Code or the prevailing local code.

HOOD EXHAUST

NOTE: Read these next two pages only if you plan to vent your exhaust to the outside. If you plan to
recirculate the air back into the room, proceed to page 11.

NOTE: For back exhaust, care should be taken to align the exhaust with the space between studs, or the wall should

General information

NOTE: If you need to install ducts, note that the total

duct length of 3 ¼˝ x 10˝ rectangular or 6˝ diameter
round duct should not exceed 140 equivalent feet.

Outside ventilation requires a HOOD EXHAUST DUCT.
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.

Exhaust connection:

The hood exhaust has been designed to mate with a
standard 3 ¼˝ x 10˝ rectangular duct.

If a round duct is required, a rectangular-to-round
transition adaptor must be used. Do not use less

than a 6˝ diameter duct.

Maximum duct length:

For satisfactory air movement, the total duct length of
3 ¼˝ x 10˝ rectangular or 6˝ diameter round duct should
not exceed 140 equivalent feet.

Elbows, transitions, wall and roof
caps, etc. present 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
equivalent length in feet of some typical ducts.
