Installation & Safety Guidelines

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

Important Cautions:

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

• Replacement Schedule: For optimal algae control and 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 over time).

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