Why Replace Annually?
UV lamps degrade over time and lose their ability to neutralise bacteria, viruses, and protozoa after 12 months of operation — even when they still appear to be lit. Filters also accumulate sediment and contaminants, reducing flow rate 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
- Restore water supply and check for leaks
- Power on and reset your system timer if applicable
