Installation Instructions
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 insure 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 house fuse or
open circuit breaker before
beginning 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 59 pound product, plus additional oven loads
of up to 50 pounds or a total weight of 109
pounds.
CAUTION: For personal safety, this product
cannot be installed in cabinet arrangements such
as an island ora peninsula. It must be mounted to
BOTH a top cabinet AND a wall.
NOTE: For easier installation and personal
safety, it is recommended that two people install
this product.
You should have the wall receptacle and circuit
checked by a qualified electrician to make sure
the receptacle is properly grounded.
Where a standard two-prong wall receptacle is
encountered, it is very important to have it
replaced with a properly grounded three-prong
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.
ELECTRICAL REQUIREMENTS
Product rating is 120 volts AC, 60 Hertz, 14.5 amps
(13 amps, CANADA) and 1.65 kilowatts (1.5
kilowatts, CANADA). 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 20 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.
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)
wall receptacle to
Insure proper
ground exists
before use
minimize the possibility
of electric shock hazard
from this appliance.

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 exhaust with space between studs, or wall should be
prepared at the time it is constructed by leaving enough space between the wall studs to accommodate
exhaust.

Installation Instructions
NOTE: If you need to install ducts, note that the total
duct length of 3¼" x 10" rectangular or 6" diameter
round duct should not exceed 60 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 3¼"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
3¼" x 10" rectangular or 6" diameter round duct
should not exceed 60 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 approximate feet of equivalent length of
some typical ducts.

Installation Instructions
1.PLACEMENT OF THE MOUNTING PLATE
A. REMOVING THE MICROWAVE
OVEN FROM THE CARTON/
REMOVING THE MOUNTING
PLATE
1, Remove the installation instructions, Exhaust
adaptor, filters, glass tray and the small hardware
bag. Do not remove the Styrofoam protecting the
front of the oven.
2. Fold back all 4 carton flaps fully against carton
sides. Then carefully roll the oven and carton over
onto the top side. The oven should be resting in
the Styrofoam.
B. FINDING THE WALL STUDS
1. Find the studs, using one of the following
methods:
A. Stud finder-a magnetic device which locates
nails.
OR
3. Pull the carton up and off the oven.
4. Remove and properly discard plastic bags.
Screws
Mounting Plate _
5, Remove the 2 screws from the mounting plate.
This plate will be used as the rear wall template
and for mounting.
NOTE: You will have to reuse two screws in original
location of outcase after removing mounting plate.
Screws
T
B. Use a hammer to tap lightly across the
mounting surface to find a solid sound. This
will indicate a stud location.
2, After locating the stud(s), find the center by
probing the wall with a small nail to find the edges
of the stud. Then place a mark halfway between
the edges. The center of any adjacent studs
should be 16" or 24" from this mark.
3, Draw a line down the center of the studs.
THE MICROWAVE MUST BE CONNECTED TO AT
LEAST ONE WALL STUD.
