GROUNDING INSTRUCTIONS

GROUNDING INSTRUCTIONS

This appliance must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This appliance is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded.

WARNING – Improper use of the grounding plug can result in a risk of electric shock. The electrical requirements are 120 Volt, 60 Hz AC only, 20 Amp or more fused electrical supply. It is recommended that a separate circuit serving only this appliance be provided. When installing this appliance, observe all applicable codes and ordinances. 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 appliance. The marked rating of the extension cord should be AC 120 Volt 20 Amp. Consult a qualified electrician or serviceman if the grounding instructions are not completely understood or if doubt exists as to whether the appliance is properly grounded.

INSTALLATION

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 page 5.

2.Exhaust vents are on the back of the unit near the top. Install the unit at least 2 inches 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 permanently placed, drill a hole through the counter top for a 3/16 inch (0.48 cm) selftapping screw. The hole should be 12 inches (30.5 cm) from the hinge side of the oven door and 51/ 4 inches (13.3 cm) back from the front edge of the removable filter.
