Over-the-Range Microwave Oven: SMO1461GS
INSTALLATION MANUAL
IMPORTANT SAFETY INSTRUCTIONS
BEFORE YOU BEGIN
Read all instructions thoroughly before installing the Over-the-
Range Microwave Oven.
Note to Installer – Leave these instructions with the consumer.
• Skill level – Installation of this appliance requires basic mechani-
cal and electrical skills. We recommend that two people install
this microwave oven.
• Proper installation is the responsibility of the installer.
• Product failure due to improper installation is not covered under
the Warranty.
• If a new electrical outlet is required, its installation should be
completed by a qualied electrician before the Over-the-Range
Microwave oven is installed. See ELECTRICAL GROUNDING
INSTRUCTIONS section.
Note to Consumer – Keep these instructions for future reference.
• Save these instructions for local inspector’s use.
• Observe all governing codes and ordinances.
ELECTRICAL
GROUNDING
INSTRUCTIONS
THIS APPLIANCE MUST BE PROPERLY GROUNDED
TO AVOID SEVERE OR FATAL SHOCK. PLEASE READ
CAREFULLY.
This appliance must be grounded. This oven is equipped with a cord
having a grounding wire with a grounding plug. It must be plugged
into a wall receptacle that is properly installed and grounded in
accordance with the National Electrical Code and local codes and
ordinances. In the event of an electrical short circuit, grounding
reduces risk of electric shock by providing an escape wire for the
electric current.
WARNING
Improper use of the grounding plug can result in
risk of electric shock.
The oven is equipped with a
3-prong grounding plug. NEVER
cut or remove the grounding pin
from the plug.
The Power Supply Cord and plug
must be connected to a separate
120 Volt AC, 60 Hz, 15 Amp, or more branch circuit, single grounded
receptacle. The receptacle should be located inside the cabinet
directly above the Microwave Oven/Hood mounting location.
Note: If you have any questions about the grounding or electrical
instructions, consult a qualied electrician or serviceperson. Neither
Sharp nor the dealer can accept any liability for damage to the oven
or personal injury resulting from failure to observe the correct
electrical connection procedures.
CAUTION
FOR PERSONAL SAFETY
• Remove the house fuse or open the circuit breaker before begin-
ning installation to avoid severe or fatal shock injury.
• The mounting surface must be capable of supporting the cabinet
load, in addition to the added weight of this 50-70 lb (22.6-31.7
kg) product, plus additional oven loads of up to 50 pounds (22.6
kilograms) for a total weight of 100-120 lb (45.2-54.3 kg).
• 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.
• For easier installation and personal safety, we recommend that
two people install this microwave oven.

GENERAL INFORMATION
HOOD EXHAUST
Note: Read the 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.
All ductwork must be metal. DO NOT use plastic duct. Check that
all connections are made securely.

the bottom corners of the damper will have to be cut to t, using the
tin snips, in order to allow free movement of the damper.

GENERAL INFORMATION
If you need to install ducts, note that the total duct length of 3 1/4"
x 10" (8.3 x 25.4 cm) rectangular or 6" (15.2 cm) diameter round
duct should not exceed 140 equivalent feet (42.7 m).
Outside ventilation requires a HOOD EXHAUST DUCT. Read
the following carefully.
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 connect with a standard
3 1/4" x 10" (8.3 x 25.4 cm) rectangular duct.
If a round duct is required, a rectangular-to-round transiting adapter
must be used. Do not use less than a 6" (15.2 cm) diameter duct.
MAXIMUM DUCT LENGTH
For satisfactory air movement, the total duct length of
3 1/4"x 10" (8.3 x 25.4 cm) rectangular or 6" (15.2 cm) diameter
round duct should not exceed 140 equivalent feet.
ELBOWS, TRANSITIONS, WALL AND ROOF
CAPS, ETC.
Elbows, adapters, wall and roof caps, etc. present additional resis-
tance to air ow and are equivalent to a section of straight duct which
is longer than their actual physical size. When calculating the total
length, add the equivalent lengths of all transitions and adapters
plus the length of all straight duct sections. The chart on the right
shows the approximate measurement of equivalent length of some
typical ductwork parts.
Use the values in the chart for calculating total ductwork, which
should be less than 140 equivalent feet (42.7 m). Equivalent lengths
of duct pieces are based on actual tests and reect requirements for
good venting performance with any vent hood.
IMPORTANT: If a rectangular-to-round transition adapter is used,
the bottom corners of the damper will have to be cut to t, using the
tin snips, in order to allow free movement of the damper.

STEP-BY-STEP INSTALLATION GUIDE
PLACEMENT OF THE MOUNTING PLATE
A. REMOVE THE MICROWAVE OVEN AND MOUNTING
PLATE FROM CARTON
1. Open the carton and remove the upper foam from the box, but
remember to keep the accessories.
2. Pull the oven out of the carton and remove the plastic bag carefully.
3. Take the mounting bracket out from the upper foam.

B. FIND THE WALL STUDS
THE MICROWAVE MUST BE MOUNTED TO AT LEAST
ONE WALL STUD.
1. Find the wall studs using either a wall stud nder (a magnetic
device for locating nails) or a hammer to tap lightly across the
mounting surface to nd a solid sound, which indicates a wall
stud location.

Wall studs center
2. After locating the stud(s), nd the center by probing the wall with
a small nail to nd the edges of the wall stud.
3. Place a mark halfway between the edges. The center of any
adjacent wall studs should be 16" (40.6 cm) or 24" (61 cm) from
this mark.
4. Draw a line down the center of the wall studs.

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, the top
line of Rear Wall Template must align with below cabinet bottom,
the same distance as the front overhang depth. This will keep the
microwave level.
1. Measure the inside depth of the front overhang.
2. Draw a horizontal line on the back wall, an equal distance below
the cabinet bottom as the inside depth of the front overhang.
3. For this type of installation with front overhang only, align top
line of Rear Wall Template with this horizontal line, not touching
the cabinet bottom as described in step D.
Note: 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.
D. ALIGN TOP LINE OF REAR WALL TEMPLATE
Area E
Center line
CAUTION
Wear gloves to avoid cutting ngers on sharp edges.
1. Using tape measure, draw a vertical line on the wall at the center
of the 24" (61 cm) wide space.
2. Tape the Rear Wall Template on the cabinet wall, align the center
markers on the Rear Wall Template to the center line on wall,
making sure it is level and that the top line of the Rear Wall
Template is butted up against the bottom edge of the upper cabinet.
3. While taping the Rear Wall Template on the wall, draw circles
on the wall at hole A, B, C (see illustration above/actual plate
marked with arrows). THREE HOLES MUST BE USED FOR
MOUNTING. (If there are 2 wall studs in right and left side based
on center line, four holes must be used for mounting.)
4. Remove the Rear Wall Template and check the marking based on
the actual mounting plate (center line, holes A, B, C).
5. Drill holes on the circle marks (A, B, C). Drill a 3/16" (4.7 mm)
hole at C for lag screw and two 5/8" (15.88 mm) holes at A and
B for toggle bolts.
Note: DO NOT MOUNT THE PLATE AT THIS TIME.
6. If the Rear Wall Template is damaged or unusable, measure and
mark the wall with the dimensions described in step E.
E. MARK REAR WALL OF THE CABINET WITHOUT REAR
WALL TEMPLATE
1. The Bottom edge line of Mounting Plate must be 17 1/8" (435 mm)
from the bottom edge line of upper cabinet and must be level.
STEP-BY-STEP INSTALLATION GUIDE
2. Mounting plate end holes must be 16 11/16" (423.8 mm) from the
bottom edge line of upper cabinet and must be on a equal line
with each other. They must each be 9 3/8" (237.8 mm) from the
center line.
