What's Included in This Kit

- 5 micron Sediment Depth Filter 20" Standard – SDC-25-2005

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.
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 both filter cartridges in order
- Restore water supply and check for leaks
- Power on and reset the lamp timer if applicable
