4. Setup and Installation
Follow these steps to safely replace the shield lens in your compatible 15W LED fixture:
- Power Disconnection: Ensure the power to the LED fixture is completely turned off at the main circuit breaker. Confirm with a voltage tester.
- Access the Fixture: Carefully open or disassemble the LED fixture to gain access to the existing shield lens. This may involve removing screws, clips, or latches depending on the fixture design. Refer to your fixture's original manual for specific instructions.
- Remove Old Lens: Gently remove the damaged or old shield lens. Note how it was secured (e.g., clips, frame, sealant) to ensure proper installation of the new lens. Dispose of the old lens responsibly.
- Clean Fixture: Before installing the new lens, clean any dust, debris, or residue from the fixture's interior and the lens seating area. This ensures a proper fit and optimal light output.
- Install New Lens: Carefully position the new Ericson Manufacturing 1239TS Shield Lens into the fixture. Ensure it sits flush and is properly aligned.
- Secure Lens: Secure the new lens using the fixture's original fastening mechanism (screws, clips, frame, etc.). Do not overtighten screws, as this can crack the lens.
- Reassemble Fixture: Reassemble any parts of the fixture that were removed to access the lens. Ensure all components are securely fastened.
- Restore Power: Once the installation is complete and verified, restore power to the fixture at the circuit breaker.
- Test Functionality: Turn on the LED light to confirm proper operation and illumination.
5. Operation
The 1239TS Shield Lens is a passive component designed to protect the LED light source and diffuse light evenly. Once correctly installed, its operation is integrated with the LED fixture it is part of. It requires no separate operational controls.
6. Maintenance
Regular maintenance helps ensure optimal performance and longevity of the lens and the lighting fixture:
- Cleaning: Periodically clean the lens surface to remove dust, dirt, or debris that may accumulate and reduce light output. Use a soft, lint-free cloth dampened with a mild, non-abrasive cleaning solution (e.g., water with a small amount of dish soap). Avoid harsh chemicals or abrasive materials that could scratch or damage the lens.
- Inspection: Regularly inspect the lens for any signs of damage, suchs as cracks, discoloration, or loosening. If damage is observed, consider replacing the lens to maintain safety and performance.
- Power Disconnection for Cleaning: Always disconnect power to the fixture before cleaning or performing any maintenance.
7. Troubleshooting
The shield lens itself is a passive component and typically does not cause operational issues. Most problems after lens replacement are related to the fixture or installation.
Common Issues and Solutions:
- Light Does Not Turn On After Lens Replacement:
- Verify that the power supply to the fixture is restored at the circuit breaker.
- Check all electrical connections within the fixture (if any were disturbed during lens replacement).
- Ensure the LED light source itself is functional (this lens is for the LED only, not the entire fixture).
- Reduced Light Output or Uneven Illumination:
- Ensure the lens surface is clean and free of smudges or debris.
- Verify the lens is correctly seated and not obstructed.
- Confirm the lens is the correct type and size for your fixture.
- Lens Appears Loose or Not Seated Properly:
- Re-check the fastening mechanisms (screws, clips) to ensure they are securely engaged.
- Ensure no foreign objects are preventing the lens from seating flush.
If problems persist after following these steps, consult a qualified electrician or contact Ericson Manufacturing customer support.
