Bathrooms have many spaces where excess moisture can cause damage.
Wet bathrooms can harbor mildew and molds of all kinds and shorten the life of your bathroom walls and fixtures. A good exhaust fan can help route moist air out of a bathroom and diminish the negative effects of excessive moisture. Broan manufactures exhaust fans that can help divert air quietly and efficiently. You can wire a Broan exhaust fan using some basic materials and wiring techniques. This installation is for a ceiling-mounted fan.
Instructions
Running the Wires
1. At the main circuit breaker, turn off the power to the room where you will be installing the exhaust fan.
2. Unscrew and remove the cover of a Broan exhaust fan to expose the black, white and bare electrical wires behind it.
3. Tape the end of a length of 120-volt AC wiring to the tip of a wire running kit with electrical tape.
4. Insert the wire running kit in the ceiling behind the exhaust fan.
5. Push the wire running kit across the interior surface of the ceiling toward the location of the junction box where the switch will be installed. When you reach where the ceiling meets the wall, continue to push the wire running kit until the end appears in the wall by the junction box.
6. Pull the tip of the wire running kit through the junction box and remove the electrical tape holding the tip of the wire to the kit.
7. Tape the wire against the wall with electrical tape to prevent it from falling back inside the wall.
8. Cut the other end of the wire, which will be attached to the exhaust fan. Allow about 1 foot of extra length.
9. Remove approximately 1/2 inch of insulation from the end of the wire at the exhaust fan, using a utility knife.
10. Splice the exhaust fan's black wire to the wire running to the switch, using a twist-on wire connector.
11. Using masking tape and a marker, label with the word "black" the wire at the switch. This will help you identify the wire when connecting it to the switch. Repeat running, cutting, splicing and labeling the wire with the fan's remaining white and bare wires.
12. Replace the cover on the exhaust fan and screw it into place.
Wiring the Switch
13. Splice the wire running from the fan's bare wire to the ground wire of the junction box with a twist-on wire connector.
14. Splice the wire running from the fan's white wire to the white wire from the building's electrical supply at the switch plate with a twist-on wire connector.
15. Wrap the wire running from the fan's black wire around the upper terminal, usually labeled "Top" in most switches, on the switch and tighten it in place with a screwdriver.
16. Wrap the black wire from the building's power supply at the junction box around the lower terminal on the switch and tighten it in a screwdriver.
17.Line up the screw holes of the switch with the screw holes in the junction box. Insert screws into the holes and screw them in place with a screwdriver.
18. Set the face plate of the switch in place over the switch and secure it with the included screws using a screwdriver.
