Remove Cardboard Template

The cardboard piece from the top of the microwave oven packaging is perforated. The piece inside the perforation is for use as a rear wall template.

1. Cut along the perforation to separate the template from the rest of the cardboard packaging.

2. Set the cardboard template to the side and refer to it during the “Mark Rear Wall” part of installation.

Depending on your model, it may use full carton box for packing, then skip remove cardboard template steps, but use the wall template for "Mark Rear Wall" part of installation.

Location Requirements

Check the opening where the microwave oven will be installed. The location must provide:

■ Minimum installation dimensions. See the “Installation

Dimensions” illustration.

■ Minimum one 2" x 4" (5.1 x 10.2 cm) wood wall stud and

minimum 3/8" (1 cm) thickness drywall or plaster/lath within cabinet opening.

■ Support for weight of 150 lbs (68 kg) which includes

microwave oven and items placed inside the microwave oven and upper cabinet.

■ Grounded electrical outlet inside upper cabinet. See the

“Electrical Requirements” section.

NOTES:

■ If installing the microwave oven near a left sidewall, make

sure there is at least 6" (15.2 cm) of clearance between the wall and the microwave oven so that the door can open fully.

■ Some models have a pocket handle. If installing the

microwave near a right side wall, make sure there is at least 3 inches of clearance between wall and microwave oven so you can grab the handle integrated inside the door.

■ Some cabinet and building materials are not designed to

withstand the heat produced by the microwave oven for cooking. Check with your builder or cabinet supplier to make sure that the materials used will not discolor, delaminate, or sustain other damages.

■ Cardboard template (part of

packaging) or wall template

■ Aluminum grease lters

■ Charcoal lters (Depending

on model, charcoal lters may not be included. See User Instructions.)

NOTE: Depending on model, aluminum grease lter and charcoal lter may be combined.

Materials Needed

■ Standard ttings for wall or roof venting. See the “Venting

Design Specications” section.

Special Requirements

For Wall Venting Installation Only:

■ Cutout must be free of any obstructions so that the vent t

properly and the damper blade opens freely and fully.

For Roof Venting Installation Only:

■ If you are using a rectangular-to-round transition piece, the

3" (7.6 cm) clearance needs to exist above the microwave oven so that the damper blade can open freely and fully. See “Rectangular to Round Transition” illustration in the “Venting Design Specications” section.

Electrical Requirements

WARNING

Electrical Shock Hazard

Plug into a grounded 3 prong outlet.

Do not remove ground prong.

Do not use an adapter.

Do not use an extension cord.

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

Observe all governing codes and ordinances.

Required:

■ A 120 V, 60 Hz, AC only, 15 or 20 A electrical supply with a

fuse or circuit breaker

Recommended:

■ A time-delay fuse or time-delay circuit breaker

■ A separate circuit serving only this microwave oven

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.

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.
