Sharp OVER THE RANGE MICROWAVE OVEN/HOOD SYSTEM, KOT1J0U Installation Instructions Manual

1

This Microwave Oven/Hood should be mounted against and

supported by a at vertical wall. The wall must be at for proper
installation. If the wall is not at, use spacers to ll 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 nd the location of the studs, one of the following methods

may be used:

A. Use a stud nder, a magnetic device which locates the nails

in the stud.

B. Use a hammer to tap lightly across the mounting surface to

nd 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 nd the edges of the stud and then placing a mark
halfway between the edges. The center of any adjacent studs
will normally be 16" or 24" to either side of this mark.

NOTE: In the event that the unit will be unable to be supported by any stud, it will be necessary to use
special care in the placement of the toggle bolts and top cabinet screws. See Wall Template for details.
The top cabinet should be tested to ensure it is securely attached to the wall. Place extra weight up to 110
pounds inside the top cabinet to test the support.

OVER THE RANGE MICROWAVE OVEN/HOOD SYSTEM

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 qualied electrician before the
Microwave Oven/Hood is installed. See 3 ELECTRICAL GROUNDING INSTRUCTIONS on page 2.

This Microwave Oven/Hood requires a mounting space on a wall
as shown in Figure 1.

If the space between the wall cabinets is greater than 30-inches
(36-inches or 42-inches), a Filler Panel may be used to fill

the gap between the Microwave Oven/Hood system and wall

cabinets. The Filler Panel Kit should be installed before the
Microwave Oven/Hood is installed.

For proper installation and servicing, a 2-inch space is necessary
between the top of the range backsplash and the bottom of the
Microwave Oven/Hood system.

3 ELECTRICAL GROUNDING INSTRUCTIONS

4 HOOD EXHAUST DUCT

5 TOOLS RECOMMENDED FOR INSTALLATION

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 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 qualied electrician or serviceperson.

2. 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.

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 31/4" 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 31/4" X 10" rectangular or 6"
diameter round duct should not exceed 140 feet.

Elbows, adapters, wall, roof caps, etc. present
additional 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.

• Phillips Screwdriver • 11/2" Wood Bit or Metal Hole Cutter (if metal cabinet is used)

• Electric Drill • 1/2", 5/8" and 3/32" Drill Bits

• Scissors • Saw to cut exhaust opening (if needed)

• Pencil • Measure

• Tape • Protective Drop Cloth for product and range—you may also use carton for protection
