Setup & Installation
Always ensure power is turned off at the circuit breaker before beginning any electrical installation. If you are unsure about any steps, consult a qualified electrician.
Step 1: Prepare the Ceiling
Using the provided 1:1 cutout template, mark the desired location on the ceiling. Carefully cut a 4.25-inch (108mm) hole in the ceiling. Ensure there are no obstructions like electrical wires or pipes within the ceiling space where the light will be installed.

Step 2: Wire the Junction Box
Open the junction box cover. Connect the household electrical wires (Live, Neutral, Ground) to the corresponding quick-connect terminals inside the junction box. Ensure all connections are secure and properly insulated. Close the junction box cover.

Operating Instructions
Color Temperature Selection (5CCT)
Before installing the light fixture into the ceiling, locate the 5CCT selectable switch on the side of the junction box.

Maintenance
To maintain the performance and appearance of your zouzai LED Recessed Ceiling Light, follow these simple guidelines:
- Cleaning: Ensure power is off before cleaning. Wipe the light fixture gently with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, but avoid abrasive cleaners or solvents.
- No User-Serviceable Parts: The LED components and driver are integrated and not user-serviceable. Do not attempt to open or repair the light fixture, as this will void the warranty and may pose a safety risk.
- Inspection: Periodically check the light fixture for any signs of damage or loose connections. If any issues are found, consult a qualified electrician.
Troubleshooting
If you encounter any issues with your zouzai LED Recessed Ceiling Light, refer to the following troubleshooting steps:
Light Not Turning On
- Check Power Supply: Ensure the circuit breaker supplying power to the light is in the ON position.
- Verify Wiring: Confirm that all electrical connections in the junction box are secure and correctly wired (Live, Neutral, Ground).
- CCT Switch Position: Check the 5CCT switch on the junction box. Ensure it is set to a valid color temperature and not in an intermediate position.
- Fixture Connection: Ensure the connection between the light fixture and the junction box is fully seated and secure.
Flickering Light
- Dimmer Compatibility: If using a dimmer, ensure it is compatible with LED lighting. Incompatible dimmers can cause flickering.
- Minimum Load: Some dimmers require a minimum load to function correctly. Ensure enough lights are connected to meet the dimmer's minimum wattage requirement.
- Loose Connections: Check all wiring connections for looseness, which can cause intermittent power and flickering.
