Installation & Maintenance Guide

To protect your canister filter and ensure a perfect watertight seal, please handle this delicate component with care:

Usage Instructions:

• Handling: Always hold the sleeve by its plastic base or use a clean microfiber cloth when touching the glass. Preventing the transfer of natural oils from your skin helps maintain maximum UV transmission.

• Installation: Carefully align the locking tabs on the plastic base with your filter housing, then gently push and secure the sleeve into place until it sits completely flush.

• Cleaning: During routine filter maintenance, gently wipe the outside of the glass with a soft sponge to remove any bacterial slime or calcium build-up that could block UV light.
