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.

Electrical Requirements

The electrical requirements are a 120 volt 60 Hz, AC only, 15 amp. or more
protected electrical supply. It is recommended that a separate circuit serving
only this appliance be provided.
The oven is equipped with a 3-prong grounding plug. It must be plugged into
a  wall  receptacle  that  is  properly  installed  and  grounded.  Should  you  only
have a 2-prong outlet, have a qualified electrician install a correct wall recep-
tacle.
A  3-prong  adapter  may  be  purchased  and  used  temporarily  if  local  codes
allow. Follow package directions.
A short power-supply cord is provided to reduce risk of becoming entangled in
or tripping over a longer cord.

Extension Cord

If it is necessary to use an extension cord, use only a 3-wire extension cord
that has a 3-blade grounding plug and a 3-slot receptacle that will accept the
plug on the microwave oven. The marked  rating of the extension cord should
be AC 115-120 volt, 15 amp. or more.
Be careful not to drape the cord over the countertop or table where it can be
pulled on by children or tripped over accidentally.

Notes:

1. If  you  have  any  questions  about  the  grounding  or  electrical  in-

structions, consult a qualified electrician or service person.

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.

Radio or TV Interference

Should there be any interference caused by the microwave oven to your radio or TV, check that the microwave
oven is on a different electrical circuit, relocate the radio or TV as far away from the oven as feasible or check
position and signal of receiving antenna.

GROUNDING INSTRUCTIONS

INSTALLATION

Because  your  Sharp  Commercial  Microwave  Oven  will  be  used
frequently, place it so that there is easy access for all users.

1. Be sure all electrical requirements are met. See above.
2. Air intake openings are on the back of the unit. Install the unit at

least 2 inches (5.1 cm) away from the nearest wall to permit
adequate ventilation for proper cooling and air flow in the oven.

3. Install the unit where no excessive heat or steam are generated.

Do not place next to an oven or cooking surface.

4. The unit may be secured to a countertop or stand. There is a

screw hole in the bottom of the unit. After the oven is perma-
nently placed, drill a hole through the counter top for a 3/16 inch
(

0.48 cm) 

self-tapping screw. The hole should be 1 inch (2.5 cm)

from the left side of the outer case cabinet and 7-1/8 (20.1 cm)
inches back from the front edge of the cavity face plate.
