NSTALLATION INSTRUCTIONS
lease read all instructions thoroughly before installing the Microwave Oven/Hood System. Two people are
P 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.
If the space between the wall cabinets is greater than 30-inches (36-inches or 42-inches), a Filler Panel Kit may be used to fill the gap between the Microwave Oven/Hood system and wall cabi­nets. The Filler Panel Kit is sold as an optional accessory; each kit contains two 3-inch panels. 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.

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
3
and
/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 methods may
be used:
Use a stud finder, a magnetic device which locates the nails in
A.
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 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 spe cial 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.
ARNING
W
The oven is equipped with a 3-prong grounding plug. DO NOT UNDER ANY CIRCUMSTANCES CUT OR
EMOVE THE GROUNDING PIN FROM THE PLUG.
R
he Power Supply Cord and plug must be connected to a
T 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 dam­age to the oven or personal injury resulting from failure to observe the correct electrical connection procedures.
- 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: 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.
