NS-OTR16SS9 / NS-OTR16WH9 Before you install Read these instructions completely before installing your microwave. Make sure that your space meets the mounting requirements and that you’ve gathered all needed tools and materials.
Mounting requirements • The space between the cabinets must be 30 in. (76.2 cm) wide. If the space between the cabinets is more than 30 in. (76.2 cm), you’ll need filler material to fill the gap between the microwave and cabinets. • This microwave is for installation over ranges up to 36 in. (91.4 cm) wide. • If installing the microwave beneath smooth, flat cabinets, make sure that you leave enough space for the power cord clearance.
NS-OTR16SS9 / NS-OTR16WH9 Exhaust requirements Use this section if you plan to vent your microwave outside (top or back exhaust). If you plan to recirculate the air back into the room, skip to “Removing your microwave” on page 9. When installing exhaust vents: • Use the most direct route with as few elbows/transitions as possible. This helps prevent blockages and ensures that the exhaust is being vented correctly. • Your microwave is designed to mate with a standard 3-1/4” × 10” rectangular duct.
Equivalent duct length table To calculate your equivalent duct length: 1 Write the number of sections used for each of the duct pieces. 2 Multiply the number used by the equivalent length for each duct piece. 3 Add the total equivalent lengths together. This number must be less than 140 ft. Duct Pieces Rectangular-toround transition adapter Equivalent Length × Number Used = Total Equivalent Length 5 ft. × ( ) = ft. 40 ft. × ( ) = ft. 10 ft. × ( ) = ft. 5 ft. × ( ) = ft.
