UV and AXUV Disinfection Units
Instructions
Operating Information and Maintenance Instructions
Operating Information
When the UV lamp in is operating correctly, the current sensor in the control panel
reads about 0.38 amps.
• A reading of 0.20 to 0.0 amps indicates a failed or improperly connected lamp.
Different control panel types respond differently to UV lamp failures:
• AXUV units: When the sensor reads “0.0,” the AdvanTex system’s discharge
pump is automatically disabled to prevent the discharge of untreated effluent.
• VeriComm
™
Monitoring System (VMS): If the system has an operational
network connection and if the alarm delay has not been adjusted, when the
sensor reads “0” ...
~ An alert is sent to the service provider.
~ If the unit is powered through the VMS, a local alarm will sound if the
service provider does not provide service within about 18 hours.

Tip the unit housing to drain the effluent back into the basin.
Step 2d:
Lay the lamp tube/handle assembly and the unit housing on a
protective sheet of plastic.
Step 3: Clean Disinfection Unit Components
