INSTALLATION
INSTRUCTIONS
Please read all instructions thoroughly before installing the Microwave Oven/Hood System. Two people are
recommended to install this product.
If a new electrical outlet is required, its installation should be completed by a qualified electrician before the
Microwave Oven/Hood is installed. See 3 ELECTRICAL GROUNDING INSTRUCTIONS on page 2.
1 MOUNTING SPACE
This Microwave Oven/Hood requires a mounting space
on a wall as shown in Figure 1. It is designed to be used
with standard 12-inch wall cabinets.
If the space between the wall cabinets is 36 or 42 inches,
a Filler Panel Kit can be used to fill the gap. The metal
filler panels come in 3-inch wide pairs. One set is needed
for a 36-inch opening and 2 sets for a 42-inch opening.
White and black are available. See page 8 for ordering
information. The Filler Panel Kit should be installed before
the Microwave Oven/Hood is installed.

3 ELECTRICAL GROUNDING INSTRUCTIONS
This appliance must be grounded. This oven is equipped with a cord having a grounding wire with a ground-
ing 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, ground-
ing reduces risk of electric shock by providing an escape wire for the electric current.
WARNING - Improper use of the grounding plug can result in a risk of electric shock.
The oven is equipped with a 3-prong grounding plug. DO NOT UNDER ANY CIRCUMSTANCES 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:
1. If you have any questions about the grounding or electrical
instructions, consult a qualified electrician or serviceperson.
2. Neither Sharp nor the dealer can accept any liability for dam-
age to the oven or personal injury resulting from failure to
observe the correct electrical connection procedures.

2 WALL CONSTRUCTION
This Microwave Oven/Hood should be mounted against and supported by a flat vertical wall. The wall must
be flat for proper installation. If the wall is not flat, use spacers to fill in the gaps. Wall construction should be
a minimum of 2” x 4” wood studding and 3/8” or more thick dry wall or plaster/lath. The mounting surfaces
must be capable of supporting weight of 110 pounds—the oven and contents—AND the weight of all items
which would normally be stored in the top cabinet above
the unit.
The unit should be attached to a minimum of one 2” x 4”
wall stud.
To find the location of the studs, one of the following meth-
ods may be used:
A. Use a stud finder, a magnetic device which locates the
nails in the stud.
B. Use a hammer to tap lightly across the mounting surface
to find a solid sound. This will indicate stud location.
The center of the stud can be located by probing the wall
with a small nail to find the edges of the stud and then plac-
ing a mark halfway between the edges. The center of any
adjacent studs will normally be 16” or 24” to either side of
this mark.

4 HOOD EXHAUST DUCT
When the hood is vented to the outside, a hood exhaust duct is required. All ductwork must be metal;
absolutely do not use plastic duct. Check that all connections are made securely. Please read the following
carefully:
Exhaust connection: The hood exhaust has been designed to connect to a standard 3-1/4” x 10” rectangular
duct. If round duct is required, a rectangular-to-round adapter must be used.
Rear exhaust: If a rear or horizontal exhaust is to be used, care should be taken to align the exhaust with the
space between the studs, or wall should be prepared at the time it is constructed by leaving enough space
between wall studs to accommodate exhaust.
Maximum duct length: For satisfactory air movement, the total duct length of 3-1/4” X 10” rectangular or 6”
diameter round duct should not exceed 140 feet.
Elbows, adapters, wall, roof caps, etc. present addi-
tional resistance to air flow 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. Figure 4 shows the approximate feet of
equivalent length of some typical ductwork parts.
Use the values in parentheses for calculating air
flow resistance equivalent, which should total less
than 140 feet.
5 TOOLS RECOMMENDED FOR INSTALLATION
• Phillips Screwdriver • Electric Drill • 1/2”, 5/8” and 3/32” Drill Bits
• 1-1/2” Wood Bit or Metal Hole Cutter (if metal cabinet is used) • Saw to cut exhaust opening (if needed)
• Protective Drop Cloth for product and range -you may also use carton for protection

TIONS FOUND ON BOTH TEMPLATES.
THE NEXT STEP IS TO READ AND FOLLOW MOUNTING INFORMATION ON BOTH TOP CABINET AND
WALL TEMPLATES.
NOTE: THIS OVEN SHOULD BE ATTACHED TO AT LEAST ONE WALL STUD. See WALL CONSTRUC-
TION on page 2.
MOUNTING PLATE
1. Separate 4 Toggle Bolts 2, packed in the INSTALLATION HARDWARE, from the Toggle Nuts.
2. Use Wood Screws 1to attach Mounting Plate to the stud or studs. Use Toggle Bolts to attach Mounting
Plate through the holes at A, B, C and D; UNLESS THOSE HOLES ARE LOCATED ON THE STUD. Insert
one Toggle Bolt into A, B, C and D where appropriate (these correspond to the holes of the Wall Template)
and put the Toggle Nuts onto the Toggle Bolts. Figure 15.
