Annual Maintenance Kit for Sterilight S12Q-PA UV System — Triple 10" Filter Configuration
Keep your Sterilight S12Q-PA UV system delivering safe, bacteria-free water with this complete annual service kit. UV lamps lose disinfection effectiveness after 12 months — even when still glowing — so annual replacement is essential.

Why Replace Annually?
UV lamps lose disinfection effectiveness after 12 months of operation — even if they still appear to glow. Filters accumulate sediment and contaminants, reducing flow and water quality. Annual servicing keeps your system performing to its rated specification.
Important: Resetting the Ballast
After replacing the lamp, follow the instructions in your System Service Manual to reset the 365-day countdown ballast back to 365. This ensures your system accurately tracks the next service interval.
How to Service Your System
- Turn off power and water supply to the system
- Allow the lamp to cool for at least 5 minutes
- Replace the UV lamp — avoid touching the glass with bare hands
- Replace all three filter cartridges in order
- Restore water supply and check for leaks
- Power on and reset the 365-day ballast countdown
