Follow these steps for a safe and proper installation:
5.1 Preparing the Fixture
Remove the Diffuser: Gently pull the plate (A-1) along the arrow as shown in Figure 3. Remove the diffuser (Part C) from the housing (Part A) by grasping the edge of the diffuser and carefully squeezing to release it. Continue downwards to fully disengage the diffuser.

5.2 Mounting and Wiring
Prepare Junction Box: Knock out the middle hole on the fixture and install the two screws into the junction box on the ceiling. Ensure the junction box is securely mounted.
Connect Wiring: Pass all wires through the prepared hole. Connect the fixture's wires to the building's electrical wires using wire nuts. Typically, black to black (live), white to white (neutral), and green/bare copper to green/bare copper (ground). Ensure connections are secure (Figure 5, Step 1 & 2).

Figure 5: Wiring Steps
Secure Wires: Carefully push all connected wires into the junction box (Figure 5, Step 3). Ensure no wires are pinched or exposed.
Attach Fixture to Ceiling: Securely attach the fixture to the ceiling, ensuring it is flush and stable. The design ensures wires will not drop on the cover once installed (Figure 5, Step 4).
5.3 Finalizing Installation
Reinstall Diffuser: Carefully reattach the prismatic acrylic cover (diffuser) to the fixture housing. Ensure it is securely snapped into place to maximize light output and distribution (Figure 6).

8. Troubleshooting
If you experience issues with your light fixture, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |

| Light does not turn on | No power to the fixture; Loose wiring connection; Faulty wall switch; Circuit breaker tripped. | Check power supply at the circuit breaker. Verify all wire connections are secure. Test the wall switch. Reset the circuit breaker. |
| Light flickers or dims | Loose wiring connection; Incompatible dimmer switch (if applicable); Voltage fluctuations. | Check all wire connections. Ensure a compatible LED dimmer is used if dimming functionality is desired (this model is not explicitly dimmable, so avoid dimmers unless specified). Consult an electrician for voltage issues. |
