      If your Neptune Water Dispenser is leaking, make sure the compression nut is tight and that the inlet pressure doesn't exceed 100 PSI. Also, ensure the O-Ring is properly seated and lubricated with food-grade silicone. Check the O-Ring for any cracks or tears, replacing it if necessary. Inspect the quartz sleeve for cracks or chips; if damaged, contact your dealer for a replacement.

      If you experience power failure with your Neptune Water Dispenser, the unit will restart automatically once power is restored. The unit is designed for continuous operation, so avoid connecting it to timers or similar devices that cause cycling, as this can reduce the lamp's lifespan.

      If you notice poor bacterial performance with your Neptune Water Dispenser, replace the lamp if it's older than 365 days or nearing its end-of-life. Perform routine maintenance. Check the water quality against the maximum concentration levels in Table 1 of the Pre-Installation Instructions, and take corrective action if needed. Verify the flow rate against disinfection levels in Technical Specifications Table 3.
