5. Installation
Before you begin: Ensure power is OFF at the circuit breaker. Failure to do so may result in serious injury or death.
- Turn Off Power: Locate the circuit breaker or fuse that controls the light switch you are replacing. Turn it OFF. Verify power is off at the switch location using a voltage tester.
- Remove Existing Switch: Carefully remove the wall plate and unscrew the existing switch from the wall box. Disconnect the wires from the old switch. Note which wire is the 'hot' (line) wire and which goes to the light fixture (load).
- Wire the Dimmer: The P600VA-R dimmer typically has two wires for connection to the circuit. Connect one dimmer wire to the 'hot' (line) wire from the electrical box. Connect the other dimmer wire to the 'load' wire that goes to the light fixture. If a ground wire is present in the wall box, connect it to the dimmer's ground terminal (if applicable, or cap it if not used by the dimmer). Refer to the wiring diagram provided with the dimmer for specific color codes if available.
- Mount the Dimmer: Gently push the wired dimmer into the wall box. Secure it with the provided mounting screws.
- Install Wall Plate: Attach the decorative wall plate over the dimmer.
- Restore Power: Turn the power back ON at the circuit breaker.
6. Operation
The Lightolier Controls P600VA-R dimmer features a simple rotary control for both ON/OFF functionality and dimming.
- Turning ON/OFF: Push the rotary knob inward until you hear a click to turn the lights ON or OFF.
- Dimming: Rotate the knob clockwise to increase light intensity and counter-clockwise to decrease light intensity.
7. Maintenance
The Lightolier Controls P600VA-R dimmer requires minimal maintenance.
- Cleaning: To clean the dimmer, wipe the surface with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure power is off before cleaning.

8. Troubleshooting
If you experience issues with your dimmer, refer to the following common problems and solutions:
- Lights do not turn ON:
- Check if the circuit breaker is ON.
- Verify that the light bulb(s) are working and properly installed.
- Ensure all wiring connections are secure.
- Lights do not dim or flicker:
- Confirm that the light bulbs are dimmable. Not all LED or CFL bulbs are compatible with standard dimmers.
- Check that the total wattage of the connected lights does not exceed the dimmer's 600VA rating.
- Ensure wiring connections are secure.
- Dimmer is hot to the touch:
- A dimmer operating at or near its maximum capacity may feel warm. If it is excessively hot, turn off power and check the load wattage. Reduce the load if necessary.
If problems persist, contact a qualified electrician or Lightolier customer support.
