Setup and Installation
Follow these steps to install your dimmer switch:
- Turn Off Power: Locate the circuit breaker or fuse that supplies power to the switch box. Turn off the power completely before proceeding. Verify power is off using a voltage tester.
- Remove Old Switch: Carefully remove the wall plate and unscrew the existing switch from the wall box. Disconnect the wires from the old switch, noting which wire was connected to which terminal.
- Identify Wires: You will typically find a hot wire (usually black), a load wire (to the light fixture, often black or red), and a ground wire (bare copper or green). The A600LV-W dimmer has pre-stripped wires for connection.
- Wire the Dimmer:
- Connect the dimmer's black wire to the hot (line) wire from the electrical box.
- Connect the dimmer's other black wire to the load wire (to the light fixture).
- Connect the dimmer's green or bare copper wire to the ground wire in the electrical box.
Use appropriate wire connectors and ensure all connections are tight and secure.
- Mount the Dimmer: Carefully fold the wires into the electrical box. Mount the dimmer into the wall box using the provided screws.
- Install Wall Plate: Attach the decorative wall plate (not included) over the dimmer.
- Restore Power: Turn the power back on at the circuit breaker.

Maintenance

- Cleaning: To clean the dimmer, wipe it with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure power is off before cleaning.
- Bulb Replacement: Always turn off power at the circuit breaker before replacing light bulbs connected to the dimmer.
Troubleshooting
If you experience issues with your dimmer, try the following solutions:
- Lights do not turn on:
- Check if the circuit breaker is tripped.
- Ensure all wire connections are secure.
- Verify that the light bulbs are working and correctly installed.
- Lights flicker or hum:
- Ensure the total wattage of the incandescent bulbs does not exceed the dimmer's maximum rating (600W).
- Confirm that only incandescent bulbs are being used.
- Check for loose wire connections.
- Dimmer is warm to the touch:
- It is normal for dimmers to feel warm during operation. If it is excessively hot, ensure the load does not exceed 600W and that proper ventilation is maintained in the electrical box.
