6. Installation Instructions
Follow these steps to properly install your ECOELER LED Surface Mount Downlight. Ensure power is disconnected at the circuit breaker before starting.
- Prepare the Fixture: Gently remove the trim ring from the luminaire. This will expose the mounting holes and the CCT selection switch.
- Select Color Temperature: Before mounting, locate the 5CCT selection switch on the side of the fixture. Slide the switch to your desired color temperature (2700K, 3000K, 4000K, 5000K, or 6000K). This setting cannot be changed easily after installation.
- Connect Wiring: Connect the fixture's wires to the corresponding wires in your 4-inch junction box using the provided wire nuts. Connect the black wire to the live wire, the white wire to the neutral wire, and the green wire to the ground wire. Ensure all connections are secure.
- Mount the Fixture: Align the fixture with the junction box. Secure the luminaire to the junction box using the provided screws.
- Attach the Trim: Once the luminaire is securely mounted, twist the trim ring back onto the luminaire until it is firmly in place.
- Restore Power: Restore power at the circuit breaker.
