UV Service Screen
2. Screen Select Menu: This menu is accessed through the function button on any screen and allows navigating to the
other HMI screens.
3. UV Service Screen: Contains countdown timers that track the hours remaining until service is due on listed UV
components. Once service is complete, the user will use the specific function button to reset the corresponding service
countdown timer. The hours remaining on the countdown timers are used to determine service messaging and alert
reminders:
• More than 10% remaining = no banner message
• 10% remaining = “SERVICE SOON” banner message
• 5% remaining = “SERVICE REQUIRED” banner message
• 0% remaining = “SERVICE PAST DUE” alert banner message with yellow screen background
History Screen
4. History Screen: Contains the runtime hour meter of the unit and the fault history table.
• The runtime hour meter indicates the actual on time of the UV system, to the closest 1/10 hour.
• The fault history table will indicate the fault and the accompanying time stamp, which is relative to the runtime
hour meter.
• Up to ten faults are listed with the most recent at the top of the table.
• The function buttons allow navigation through the fault history table screens.
Fault Counters Screen
5. Fault Counters Screen: Contains a list of possible faults for the system (model dependent) and how many faults have
occurred. The fault count can be used during troubleshooting to identify common faults in the system. All fault counts
can be reset through the function key.
Banner Message
6. Banner Message: Located on the top of all screens, this field will provide messages and alerts relative to the real-time
operation of the unit.
3C. System Shut-Down
Followed for servicing or storage.
1. Shut off water flow to the unit and/or close isolation valves if available.
2. Shut off power at the breaker.
3. Open enclosure door to access internal components.
NOTE:
Water pressure may still be present depending on system plumbing. Ensure water pressure is relieved prior to
servicing any water plumbing components.
3D. Water Chemistry
The UV-C Pro will provide the benefits of UV-C germicidal disinfection treatment with minimal impact to other water
chemistry parameters. However, chlorine or other sanitizer residual levels must be maintained as required to meet local
codes. Regular residual testing must be performed as usual.
