1. Control must be grounded when installed.
2. All wiring should conform to the National Electrical Code and local
regulations.
3. Never connect control across line voltage - connect control in series with
motor and line voltage.
4. Do not exceed maximum amperage rating of the control.

Installation and Operation:
1. Turn power off at circuit breaker panel or fuse box.
2. Mounting: Use standard 2” single or double gang wall box. Connect only to line voltage shown on control.
3. Run conduit between the wall box, power source and the fan units being controlled. Leave approximately
six inches of wire in the box for connections (see figure 1).
4. Make wiring connections (see figure 2). Connect control leads as per diagram to switch box leads. Make
sure wire strands are straight and attach the wire leads of the control to the circuit wires by twisting them
together. Twist a wire nut onto each connection.
5. Check all connections for tightness, leave no exposed copper conductor.
6. Position connections in box, leaving room for control.
7. Install speed control in wall box using screws supplied. Secure control with outer bracket tabs.
8. Install front dial plate. (Remove protective plastic on face of dial plate.)
9. Turn main control shaft counter-clockwise until a click is heard.
10. Attach control knob by pressing onto shaft firmly so that pointer is in off position.
11. Restore power at circuit breaker panel or fuse box.
12. To turn control on, turn knob clockwise until a click is heard. To decrease fan speed, continue rotating knob

is suitable for mounting in a metal or polymetric field enclosure. Control must not be used at ratings exceeding
those clearly marked on the device.
Technical specifications subject to change without notice.
Speed Adjustment:
NOTE: Factory preset low speed setting is low speed setting normally acceptable in most installations. In
the event slower low speed setting is desired, read the following additional instructions:
1. Set the control on low setting and remove knob and cover plate.
2. Locate minimum speed setting (either on side or front panel of control) and adjust with screwdriver by
turning slotted white screw clockwise (to slow speed range) or counter-clockwise (to increase speed range).
3. Motor will now operate from this preset minimum to full speed.
4. Do not adjust so fan/motor stops while control is in the “on” position.
Reversing Switch
WARNING: Do not change direction of fan while fan is in motion.
