Wiring Instructions
Ensure power is OFF at the circuit breaker before beginning. This dimmer can be wired for single-pole (one location control) or 3-way (two location control) applications. Refer to the wiring diagram provided with your product for specific connections. Generally, connect the dimmer's wires to the corresponding house wires using wire connectors.
- Identify Wires: Identify the hot (line), load (to light fixture), and traveler wires (for 3-way applications).
- Single-Pole Wiring: Connect the dimmer's line wire to the hot house wire, and the dimmer's load wire to the load house wire. Cap off any unused traveler wires.
- 3-Way Wiring: Connect the dimmer's common wire to the hot house wire. Connect the two traveler wires from the dimmer to the two traveler wires from the other 3-way switch. Connect the load wire from the dimmer to the load house wire.
- Grounding: Connect the dimmer's green ground wire to the bare copper or green ground wire in the wall box.
- Mounting: Carefully fold wires into the wall box, mount the dimmer using the provided screws, and attach the wallplate (sold separately).
- Restore Power: Turn power back ON at the circuit breaker.
Operating Instructions

Troubleshooting
| Problem | Solution |
|---|---|
| Lights do not turn ON. | Check that the circuit breaker is ON. Verify all wiring connections are secure. Ensure the light bulb is functional and properly screwed in. |
| Lights flicker or do not dim properly. | Ensure that the light bulbs are specifically rated as dimmable CFL or LED. Incandescent bulbs must be compatible with dimmers. Check for minimum load requirements for CFL/LED bulbs. |
| Dimmer feels warm to the touch. | It is normal for dimmers to feel warm during operation. If it is excessively hot, ensure the total wattage of connected lights does not exceed the dimmer's maximum rating (600W Incandescent, 150W CFL). |
| Dimmer does not respond to controls. | Turn off power at the circuit breaker, wait 30 seconds, then turn power back on. Recheck wiring connections if the issue persists. |
