Installation 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 63–85 pound
product, plus additional oven loads of up to 50 pounds
or a total weight of 113–135 pounds.
CAUTION: For personal safety, this product cannot
be installed in cabinet arrangements such as an island or
a 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.
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 minimize the possibility
of electric shock hazard
from this appliance.
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, 15 amps and
1.58 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- to 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.
Ensure proper
ground exists
before use

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 6.
OUTSIDE TOP EXHAUST (EXAMPLE ONLY)
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.
* IMPORTANT: If a rectangular-to-round transition adaptor is used, the bottom corners of the damper
will have to be cut to fit, using the tin snips, in order to allow free movement of the damper.

* IMPORTANT: If a rectangular-to-round transition

to allow free movement of the damper .
NOTE: If you need to install ducts, note that the total
duct length of 31⁄4 ″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 31⁄4″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
31⁄4″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 approximate feet
of equivalent length of some typical ducts.

Find the studs, using one of the following
methods:
A. Stud finder – a magnetic device which
locates nails.
OR
B. Use a hammer to tap lightly across the
mounting surface to find a solid sound.
This will indicate a stud location.
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.
Draw a line down the center of the studs.
THE MICROWAVE MUST BE CONNECTED TO
AT LEAST ONE WALL STUD.

DETERMINING WALL PLATE LOCATION UNDER YOUR CABINET
C.
Your cabinets may have decorative trim that interferes
with the microwave installation. Remove the decorative
trim to install the microwave properly and to make it
level.
THE MICROWAVE MUST BE LEVEL.
Use a level to make sure the cabinet bottom is level.
If the cabinets have a front overhang only, with no
back or side frame, install the mounting plate down
the same distance as the front overhang depth. This
will keep the microwave level.
Measure the inside depth of the front overhang.
Draw a horizontal line on the back wall an equal
distance below the cabinet bottom as the inside
depth of the front overhang.
For this type of installation with front overhang only,
align the mounting tabs with this horizontal line, not
touching the cabinet bottom as described in Step D.

ALIGNING THE WALL PLATE
Draw a vertical line on the wall at the center of the
30″wide space.
Use the mounting plate as the template for the rear
wall. Place the mounting plate on the wall, making
sure that the tabs are touching the bottom of the
cabinet or the level line drawn in Step C for cabinets
with front overhang. Line up the notch and centerline
on the bottom of the mounting plate to the centerline
on the wall.
While holding the mounting plate with one hand,
draw circles on the wall at holes A, B, C and D
(see illustration above/actual plate marked with
arrows). Four holes must be used for mounting.
NOTE: Holes C and D are inside area E. If neither
C nor D is in a stud, find a stud somewhere in area E
and draw a fifth circle to line up with the stud. It is
important to use at least one wood screw mounted
firmly in a stud to support the weight of the microwave.
Set the mounting plate aside.
Drill holes on the circles. If there is a stud, drill a 3⁄16″
hole for wood screws. For holes that don’t line up with
a stud, drill a 5⁄8 ″hole for toggle bolts.
NOTE: DO NOT MOUNT THE PLATE AT THIS
TIME.
