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.
