Please read all safety instructions carefully before installing or operating the LSE Lighting GPH793T5L/4P UV-C Replacement Lamp. Failure to follow these instructions may result in serious injury or damage to the product.
- UV-C Radiation Hazard: UV-C light is extremely harmful to eyes and skin. NEVER look directly at an illuminated UV-C lamp. Avoid direct exposure to UV-C radiation.
- Protective Gear: Always wear appropriate UV-protective eyewear (goggles or face shield) and skin protection (long sleeves, gloves) when handling or working near an active UV-C lamp.
- Installation: Ensure the power supply to the UV system is completely disconnected before attempting installation, removal, or maintenance of the lamp.
- Handling: Do not touch the glass surface of the lamp with bare hands. Oils from your skin can create hot spots, reducing lamp life. If the lamp is accidentally touched, clean it with a high-strength isopropyl alcohol wipe before installation.
- Disposal: UV-C lamps contain mercury. Dispose of lamps according to local, state, and federal regulations. Do not dispose of in regular household waste.
- Compatibility: Use this lamp only in UV systems designed for GPH793T5L/4P or GPH793T5L/4 lamps. Using an incompatible lamp may cause system malfunction or damage.
- Children and Pets: Keep UV-C lamps and systems out of reach of children and pets.

5. Maintenance
Regular maintenance ensures the optimal performance and longevity of your LSE Lighting GPH793T5L/4P UV-C lamp and the overall UV system.
Maintenance Guidelines:
- Lamp Replacement: UV-C lamps have a finite effective life. While the lamp may still glow, its germicidal effectiveness diminishes over time. Replace the lamp according to your UV system manufacturer's recommendations, typically every 9-12 months, or as indicated by your system's lamp life monitor.
- Cleaning: If the quartz sleeve (if applicable) or the lamp itself becomes dirty, turn off and unplug the system. Allow the lamp to cool. Wearing gloves, carefully remove the lamp or sleeve and clean it with a lint-free cloth dampened with isopropyl alcohol. Do not use abrasive cleaners.
- Visual Inspection: Periodically inspect the lamp and its connections for any signs of damage, discoloration, or loose connections. If any damage is observed, replace the lamp immediately.
