1. For this installation, you will need (3) 2 wire Romex, double-gang retrot box, an 8 Hour Timer,
and a HIGH-LOW-OFF Switch.
2. Using your rst 2 wire Romex, tape the white common wire because we are going to use it for
low speed. Attach the white wire to the top gold screw on the right of the switch. Then, attach
the black wire to the bottom gold screw. (see Figure 4.2A)
3. With a piece of bare copper wire, attach it to the green ground screw on the switch.
4. Using the second 2 wire romex that’s going to your timer, use one of the supplied wire nuts to
tie the black wire to the black wire on the timer. Tie the white wire from the 2 wire Romex to the
white wire on the timer.
5. Using a wire nut, tie all bare copper wires together with the green ground wire on the timer.
6. Attach the red leg wire from the timer to the top gold screw on the left of the switch. Finish up
the installation of the timer and switch and switch cover plate.
