WARNING

NOTE: The outlet should be on a circuit dedicated to the

microwave oven 120V, 60Hz., AC only with a 15 or 20A fused electrical supply.

NOTE: Do not use an extension cord.

Keep the power cord dry and do not pinch or crush it.

IMPORTANT: If you do not have the proper wall outlet, you

MUST have one installed by a qualified electrician.

THIS OVEN MUST BE PROPERLY VENTED!

You may vent your oven in one of three ways:

Roof-venting If your oven is located on an outside wall near the roof, as in Figures 5 (31/4" x 10" duct)

and 6 (6" round duct.)

Wall-venting If your oven is located on an outside wall on the first floor of your house, as in Figure 7

(31/4" x 10" duct) and Figure 6 (6" round duct.)

Room-venting If your oven is located on an inside wall of your house, as in Figure 8.

REMEMBER AS YOU INSTALL THE VENTING:

• Keep the length of the ductwork and the number of elbows to a minimum to ventilate your oven efficiently.

See examples on page 9.

• Keep the size of the ductwork the same.

• Do not install two elbows together.

• Use duct tape to seal all joints in the duct system.

• Use caulking to seal the exterior wall or roof opening around the cap.
