5. Installation Instructions
This UV lamp is a replacement component. Refer to the original equipment manufacturer's (OEM) manual for specific installation procedures for your UV system. The following are general guidelines:
- Power Disconnection: Ensure the power supply to the UV system is completely disconnected before beginning installation.
- Protective Gear: Wear UV-rated eye protection and gloves to prevent exposure to residual UV light or accidental activation.
- Remove Old Lamp: Carefully remove the old UV lamp from its housing. Handle with care as it may be fragile.
- Clean Quartz Sleeve (if applicable): If your system uses a quartz sleeve, clean it thoroughly with a lint-free cloth and a mild cleaning solution (e.g., vinegar or isopropyl alcohol) to ensure optimal UV transmission.
- Install New Lamp: Gently insert the LSE Lighting 523035 UV Lamp into the system's lamp socket. Ensure the 4-pin base aligns correctly and seats firmly. Do not force the lamp.
- Secure Lamp: Follow your system's instructions to secure the lamp in place.
- Reconnect Power: Once the lamp is securely installed and all covers are replaced, reconnect the power supply.
- Verify Operation: Check for proper lamp operation according to your system's indicators.
Note: Avoid touching the quartz glass directly with bare hands, as oils from your skin can create hot spots and reduce lamp life. If touched, clean with alcohol and a lint-free cloth.
6. Operating Instructions
The LSE Lighting 523035 UV Lamp operates automatically once installed in a compatible UV system and powered on. Its primary function is to emit UVC light for sterilization purposes in air, surface, or water applications.
- Ensure the UV system is properly installed and maintained according to its manufacturer's guidelines.
- The lamp will begin emitting UVC light immediately upon receiving power.
- Do not operate the lamp outside of its intended UV system.

7. Maintenance
To ensure optimal performance and longevity of your LSE Lighting 523035 UV Lamp:
- Lamp Replacement: UV lamps have a finite effective life. While the lamp may still glow, its UVC output diminishes over time. Replace the lamp annually or as recommended by your UV system manufacturer to maintain effective sterilization.
- Cleaning: If your system includes a quartz sleeve, clean it periodically (e.g., every 3-6 months) to remove any buildup that could block UV light. Always disconnect power and wear protective gear before cleaning.
- Storage: Store spare lamps in their original packaging in a cool, dry place away from direct sunlight and extreme temperatures.
