Electrical requirements

AWARNING

Electrical Shock Hazard

¢ Electrical ground is required on this appliance.

¢ Do Not ground to a gas pipe.

¢ Do Not modify the power supply cord plug. If it does not fit the outlet, have a proper ouilet installed by a qualified electrician.

* Do Not have a fuse in the neutral or grounding circuit. A fuse in the neutral or grounding circuit could result in an electrical shock.

* Do Not use an extension cord with this appliance.

« Check with a qualified electrician if you are in doubt as to whether the appliance is properly grounded.

Failure to follow these instructions could result in serious injury or death.

If codes permit and a separate grounding wire is used, it is recommended that a qualified electrician determine that the grounding path is adequate.

IMPORTANT:

Save Installation Instructions for local electrical inspector’s use.

A 120-volt, 60-Hz, AC-only, 15- or 20-ampere, fused electrical supply (located in the upper cabinet as close as possible to the microwave oven) is required. A time-delay fuse or circuit breaker is recommended. It is recommended that a separate circuit serving only this appliance be provided.

Recommended grounding method

For your personal safety, this appliance must be grounded. This appliance is equipped with a power supply cord having a 3-prong grounding plug. To minimize possible shock hazard, the cord must be plugged into a mating 3-prong grounding- type wall receptacle, grounded in accordance with the National Electrical

Code, ANSI/NFPA 70 — latest edition*, and all local codes and ordinances. (See Figure

1.) If a mating wall receptacle is not available, it is the personal responsibility and obligation of the customer to have a properly grounded, 3-prong wall receptacle installed by a qualified electrician.

Venting requirements

Ductwork needed for Installation is not included. Wall and roof caps used must have back-draft damper.

AWWARNING

Fire Hazard

* Venting system must terminate to the outside.

¢ Do Not terminate the ductwork in an attic or other enclosed space.

¢ Do Not use 4" laundry-type wall caps.

* Do Not use plastic ductwork.

Failure to follow recommended venting procedures may result in a fire.

CAUTION: To reduce risk of fire and to properly exhaust air, be sure to duct air outside. - Do Not vent exhaust air into spaces within walls or ceilings or into attics, crawl spaces or garages.

Rigid metal ductwork is recommended.

Flexible metal ductwork is Not recommended. If flexible metal ductwork is used, calculate each foot of flexible metal ductwork as two feet of straight metal ductwork. Flexible metal elbows count twice as much as standard elbows. Use metal ductwork only.

Determine which venting method (roof- venting or wall-venting) you need to use.

This microwave hood is equipped for roof- or wal-venting installation.

The length of the ductwork and number of elbows should be kept to a minimum to provide efficient performance. The size of ductwork should be uniform. Do Not install two elbows together. Use duct tape to seal all joints in the duct system, Use caulking to seal exterior wall or roof opening around cap. Figures 2-5 show common venting methods and types of materials needed.

Note: If the rear exhaust method is chosen, be sure that there is proper clearance within the wall for the exhaust duct.
