Why Replace a Faulty Ballast?
A failing ballast can cause the UV lamp to flicker, underperform, or fail completely — leaving your water untreated. If your UV system is not disinfecting effectively, the ballast is often the culprit. Always replace with a compatible wattage-rated ballast.
How to Replace Your UV Ballast
- Turn off the UV system and disconnect power
- Turn off the water supply
- Remove the ballast cover
- Disconnect the lamp and power leads from the old ballast
- Install the new ballast and reconnect all leads
- Replace the cover, restore water supply, and power on
- Reset the 365-day countdown timer
- Verify the UV lamp is operating correctly
