Using an exhaust fan in the bathroom helps prevent mold from developing in this warm, moist area. It is natural for a person to turn off this fan after stepping out of a shower. However, there may still be moisture within the air. Equipping the fan with a timer enables continued circulation without wasting energy. The fan will operate for the desired period and shut off automatically.
You will need:
Step 1: At the electric panel, turn off the power to the wall switch that will house the timer control. Use the screwdriver to remove the plate that covers the switch.
Step 2: Use the wire tester to verify that the electrical circuit is safe to touch. Remove the switch toggle.
Step 3: Remove the switch and mark the wires with the wire nuts for tracking purposes.
Step 4: Measure the area needed for double work box installation, using the measuring tape. With the pencil, mark the appropriate spots on the wall. The level should be used to verify that all marks are level.
Step 5: Cut into the drywall with your utility knife, cutting along the outline for the work box.
Step 6: Separate the wiring for the light switch and the exhaust fan. Pull each of the wires into the work box and then use the screwdriver to screw each in place.
Step 7: Attach the hot, neutral, and ground wires for the timer and toggle switch according to each product manufacturer’s instructions.
Step 8: Adjust the light toggle switch and timer shaft to alight with the cover on the switch plate. Screw this cover onto the light switch, using the screwdriver. Attach the timer knob and the plate.
Step 9: At the electrical panel, turn on power to the area. Test the fan timer and toggle switch to verify proper operation.
