NuTone CFVS-1N installation instructions

Solid-State Speed Control

1. Install single-gang switch box.

2. Run 120vAC, 60Hz power line to switch box.

3. Run 14/2 cable from switch box to fan location.

4. Refer to wiring diagram and make connections.

CAUTION: Be sure all wiring complies with local electrical

codes and switch and fan are properly grounded.

5. LOW SPEED ADJUSTMENT: Turn the main control shaft

fully clockwise. If the fan is not running at the desired

speed, use an insulated screwdriver to adjust the trimpot

until the desired speed is achieved (turn clockwise for

slower, counterclockwise for faster). Make low speed

adjustment so that the louvers stay open when the

ventilator is operating.
