INSTALLATION INSTRUCTIONS

Unpacking

1. Empty the microwave oven of any packing materials.

2. Clean the inside with a soft, damp cloth.

3. Check for damage, such as:

a door that is not lined up correctly

damage around the door, or

dents on the interior or exterior of the oven.

If there is any damage, do not operate the oven until a 
designated service technician has checked it and made any 
needed repairs.

Location Requirements

IMPORTANT: The control side of the unit is the heavy side. Use 
care when handling the oven.

Place the oven on a cart, counter, table or shelf that is strong 
enough to hold the oven and the food and utensils you place 
inside it.

The microwave oven should be at a temperature above 50°F 
(10°C) for proper operation.

NOTE: Some models can be built into a wall or cabinet by using 
one of the trim kits listed in the “Installation Instructions for Built-
In Trim Kit.”

Do not block the exhaust vents or air intake openings. Allow a 
few inches of space at the back of the oven where the 
exhaust vents are located. Blocking the exhaust vents could 
cause damage to the oven and poor cooking results. 

Make sure the microwave oven legs are in place to ensure 
proper airflow. If vents are blocked, a sensitive thermal safety 
device may automatically turn the oven off. The oven should 
work properly once it has cooled.

Electrical Requirements

Observe all governing codes and ordinances. A 120-Volt, 60-Hz, 
AC-only, 15- or 20-amp fused electrical supply (or circuit breaker) 
is required. (A time-delay fuse is recommended.) It is 
recommended that a separate circuit serving only this appliance 
be provided.

WARNING

Fire Hazard

Do not install the oven next to or over a heat 
source without a UL approved trim kit.

Doing so can result in death, fire, or         
electrical shock.

WARNING

Electrical Shock Hazard

Plug into a grounded 3 prong outlet.

Failure to follow these instructions can result in
death, fire, or electrical shock.

Do not use an extension cord.

Do not use an adapter.

Do not remove ground prong.

GROUNDING INSTRUCTIONS

■  

For all cord connected appliances:

 The microwave oven 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. The microwave oven 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. Consult a qualified 
electrician or serviceman if the grounding instructions 
are not completely understood, or if doubt exists as to 
whether the microwave oven is properly grounded. 

■  

For a permanently connected appliance:

 This appliance must be connected to a grounded, 
 metallic, permanent wiring system, or an equipment 
 grounding conductor should be run with the circuit 
 conductors and connected to the equipment 
 grounding terminal or lead on the appliance.

Do not use an extension cord. If the power supply cord 
is too short, have a qualified electrician or serviceman 
install an outlet near the microwave oven.
