OVER THE RANGE MICROWAVE OVEN
INSTALLATION INSTRUCTIONS
Please read all instructions thoroughly before installing the Over the Range 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.
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.
2 WALL CONSTRUCTION
This Microwave Oven/Hood should be mounted against and support-
ed 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.

3 ELECTRICAL GROUNDING INSTRUCTIONS
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
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
2. Neither Sharp nor the dealer can accept any liability for damage to the oven
- Improper use of the grounding plug can result in a risk of electric shock.

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:
is required, a rectangular-to-round adapter must be used.
Rear exhaust:
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:
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 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. Figure 4 shows the approximate feet of
equivalent length of some typical ductwork parts. Use the values
in parentheses for calculating air ow resistance equivalent, which
should total less than 140 feet.
The hood exhaust has been designed to connect to a standard 31/4" x 10" rectangular duct. If round duct
If a rear or horizontal exhaust is to be used, care should be taken to align the exhaust with the space between
For satisfactory air movement, the total duct

2. CHECK THE OVEN.
Check the oven for any damage, such as misaligned or bent door, damaged door seals and sealing surfaces, broken or loose
door hinges and latches and dents inside the cavity or on the door. If there is any damage, do not operate the oven and contact
your dealer or SHARP AUTHORIZED SERVICER.
3. Place carton upside down as shown in Figure 6-1.
4. Using cutting line around the carton, cut into two pieces (A) and (BC). See Figure 6-2.

rear side of the oven, please disregard this section and continue to Section 9.
9 VENTILATION SYSTEM
This Microwave Oven/Hood System is designed for adaptation to three types of hood
ventilation systems. Select the type required for your installation.
A. RECIRCULATING—Non-Vented, Ductless Operation
The unit is shipped assembled for recirculating.
NOTE:
1. The Exhaust Damper Assembly is not required for recirculating operation.
2. The Charcoal Filter should be replaced every 6 to 12 months, depending on use.
3. The Charcoal Filter RK-220 is also sold as an accessory. See Operation Manual
for ordering information.
B. HORIZONTAL EXHAUST — Outside Ventilation
1. Remove and save the 4 screws from Fan Cover Bracket. Remove Fan Cover
Bracket by sliding it in the opposite direction of the arrow on the Fan Cover Bracket,
as shown in Figure 8.
2. Lift Hood Fan Unit carefully and slip wires out of cavity. See Figure 9.
CAUTION:
3. Rotate the Hood Fan Unit 180° so that the fan blade openings are facing the back
of the oven. Note, you will need to lift the wire over the hood fan unit so the wire
will clear. See Figure 10 (A). Replace Hood Fan Unit into the oven. Be careful not
to pinch the wire and the Hood Fan Unit. See Figure 10 (B).
4. Put the wire back into the cavity.
5. Replace the fan cover bracket. Make sure the fan blades are visible through the
rear openings in oven before proceeding. Attach the fan cover bracket to the unit
with the 4 screws removed in step 1 above. See Figure 11. The hood fan is now
rotated for horizontal exhaust operation.
6. Attach the Exhaust Damper Assembly to the back of the mounting plate by sliding
it into the slits in the same direction as the arrow. See Figure 12. Using tapping
screw 4 x 12 mm from the INSTALLATION HARDWARE, tighten into place.
Do not pull or stretch hood fan wiring.

10 OVEN INSTALLATION
THIS OVEN CANNOT BE PROPERLY INSTALLED WITHOUT REFERRING TO THE MOUNTING INSTRUCTIONS FOUND ON
BOTH TEMPLATES.
READ AND FOLLOW MOUNTING INFORMATION ON BOTH TOP CABINET AND WALL TEMPLATES.
MOUNTING SCALE 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 18.
Refer to instructions in Wall Template.
3. Position the Mounting Plate with the Toggle Bolts attached at the wall location and insert Toggle Nuts and Bolts through the
holes in the wall with the Toggle Nuts closed. Figure 19. Use Wood Screws 1 to attach the Mounting Plate to studs.
NOTE:
4. Align the Mounting Plate carefully and hold in position while tightening Toggle Bolts. Pull Toggle Bolt toward you and turn
Before insertion, be sure you leave a space more than the thickness of the wall between the Mounting Plate and the
end of each of the Toggle Nuts (in the closed position). If you do not leave enough space, the Toggle Nut will not be able to
open on the other side of the wall. Also, once a Toggle Nut opens, it cannot be withdrawn from the hole; therefore make sure
all of the Toggles are in the correct position before insertion.

upward. See Figure 22. Take care that the power cord is able to clear
the edge of the hole as the oven is rotated upward. (In the case of a
non-recessed bottom in the top cabinet, the hole for the cord may need
to be enlarged.) Remove the carton portions.
6. Tighten the two unit mounting screws located in the grease lter openings.
See Figure 23.
7. Install grease lters by tting into the opening. Push back and up into
place. See Figure 24.
