Installation & Safety Guidelines

To get the best performance from your new UV bulb and ensure your safety during maintenance, please follow these essential guidelines:

Important Cautions:

• Safety First: UV-C light is highly harmful to the eyes and skin. Never look directly at an illuminated UV bulb or operate it outside of its protective, sealed housing.

• Replacement Schedule: For optimal algae control and continuous sterilization, it is highly recommended to replace your UV bulb every 6 to 12 months, even if it still appears to be glowing (the invisible UV-C output degrades significantly over time).

• Handling Instructions: Avoid touching the quartz glass of the new bulb with your bare fingers. Natural oils from your skin can create hot spots and significantly shorten the bulb's lifespan. Handle with a clean cloth or soft gloves during installation.
