What's Included in This Kit
- Pura UV20/UVBB Compatible UV Lamp – L-463-22-4E (463mm 22W T5 4-pin)
- 5 micron Sediment Depth Filter 20" Standard – SDC-25-2005
Note: The original system may have included a string wound 5 micron cartridge. We supply the sediment depth equivalent, which we recommend for more effective filtration. String wound available on request.
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 the filter cartridge
- Restore water supply and check for leaks
- Power on and reset the lamp timer if applicable
