Nutone manufactures both ducted and ductless ventilation fans designed for residential applications. A Nutone fan receives its power supply from a typical switch-operated 120-volt electrical circuit. The ducted models connect to a ventilation duct that terminates outside. Ductless models circulate the interior air. Never install a ductless fan in rooms requiring exhaust ventilation. Both types of Nutone fans usually install above a bathroom's ceiling with only a louver showing below the drywall. A properly installed Nutone fan can remove moist air and bad odors.
Instructions
1. Turn off the circuit breaker feeding electricity to the Nutone fan. The appropriate circuit breaker should have a label listing the fan's room.
2. Lay out the Nutone fan's placement. Bathroom fans usually mount to the ceiling near the shower or tub door. Hold the fan's housing against the drywall and trace the fan housing's outline with a pencil.
3. Poke a hoke in the center of the outline with a screwdriver. Feel around above the drywall for ceiling joists or wires. Move the outline, as needed, if a joist or wire interferes with the fan's placement.
4. Cut the outline with a drywall saw. Use short strokes to avoid ripping the drywall. Remove the drywall square.
5. Unplug the fan unit from the Nutone fan's fan receptacle. The fan receptacle mounts to the housing's electrical compartment. The fan unit mounts to the inside of the fan's housing.
6. Remove the fan unit's mounting screw, located near the receptacle, with a hex-head screwdriver. Pull the fan unit from the housing. Save the screw.
7. Open the Nutone fan's electrical compartment using a hex-head screwdriver. Set the cover and the mounting screw aside.
8. Place a slotted screwdriver's blade into the slot in one of the knockouts. Bend the knockout back and forth until it snaps off. Knockouts provide wire access to the electrical compartment.
9. Mount the Nutone fan to the ceiling joists so that its finished edge rests even with the drywall's finished surface. If the ceiling does not have drywall, then mount the fan so its bottom edge finishes 1/2 inch below the joist. Screw the fan's mounting tabs, located on the sides of the fan's housing, to the joist with 1-inch wood screws.
10. Connect a 4-inch wide metal ventilation duct to a Nutone vented fan's duct damper. Slip the duct over the damper, located on the side of the housing, and secure it to the housing with metal-backed duct tape. Ductwork for a Nutone ventilation fan must run to an exterior termination point. Ductless fans skip this step.
11. Push the wire set from the switch into the Nutone fan's electrical compartment through the knockout hole. The switch's wire set should contain a black, a white and a bare copper wire.
12. Remove the last 3/8 inch of the insulating coating from each wire in the Nutone fan's with wire strippers. A total of five wires needs the coating removed -- two from the switch, the two connecting to the receptacle and a green ground wire.
13. Wrap the Nutone fan receptacle's black wire around the switch's black wire, the receptacle's white wire around the switch's white wire and the green wire around the bare copper wire. Spin a wire nut over each pair of wires.
14. Replace the electrical compartment's cover and the fan unit. Turn the fan blade with a finger to verify it spins freely.
15. Squeeze one of the louver's mounting springs, the wire springs connected to the interior side of the louver. Push the squeezed spring into the slot on the side of the fan's housing, then release the spring. Squeeze the second spring, place it in its respective slot and release the spring. Push the louver against the ceiling.
