Maintenance & Replacement Guidelines
To maintain maximum performance and ensure safe, germ-free water:
- Replace Annually: Even if the lamp still emits visible light, UV output declines over time — annual replacement is strongly recommended.
- Clean Quartz Sleeve: Mineral deposits or scale buildup reduces UV transmission. Clean the sleeve during lamp change-outs or per system manual.
- Handle With Care: UV lamps are fragile. Avoid touching the quartz surface with bare hands — oils and fingerprints can shorten lamp life or reduce output.
- System Shutdown: Turn off power before servicing lamp or sleeve to prevent electrical shock and ensure safety.
- Monitor System Indicators: Many Viqua units include lamp life indicators or alarms — always heed system warnings.
