If after cleaning the quartz sleeve, there is no signi fi cant improvement in the ultraviolet intensity, as shown on the intensity meter,
it may be necessary to clean the Ultraviolet Monitor’s sensor probe. The sensor probe body mounts in a fi tting, located in the
center of the disinfection chamber, and protrudes into the chamber.
1. WARNING: Disconnect power to water puri fi er.
2. Shut off water supply to the water puri fi er via the inlet and outlet shut off valves. Drain the chamber by removing the drain
plug. Once the chamber is drained, remove any old sealing tape from the threads of the drain plug, rewrap with 1/2” wide
Te

thread sealing tape, reinstall and tighten the drain plug.
3. Disconnect power to the Ultraviolet Monitor; remove from chamber by loosening the two set screws on the aluminum collar
and lifting it free from probe body.
4. Unscrew the sensor probe and remove from the chamber.
5. Remove the quartz rod sensor probe cap, from the probe body. Take care not to damage the quartz rod, o-ring or the threads
of the probe body. NOTE: It is recommended, when servicing the sensor probe, to work in a clean, dry area.
6. Once the quartz rod is removed, clean with alcohol or a mild detergent, and rinse with clean water. Stubborn stains usually
can be removed with a dilute hydrochloric acid. NOTE: Follow all manufacturer’s instructions and precautions when
handling chemicals. Once the quartz rod has been cleaned, handle the rod by the sides, to avoid getting fi ngerprints on the
quartz rod faces.
7. Clean the probe body, by removing any dirt or deposits on all surfaces. o-rings should be inspected and can be replaced if
worn or damaged.
8. Reassemble, replacing the o-rings, quartz rod and securing in place with the quartz rod sensor probe cap. Tighten the quartz
rod sensor probe cap by hand only, DO NOT USE HAND TOOLS . Tightening with hand tools may damage the quartz rod
or o-ring seal.
9. Reinstall sensor probe into the center fi tting of the chamber and hand tighten.
10. Slowly restore water supply to the water puri fi er, pressurize, and check for leaks. Once it is determined that there are no
leaks, inlet valve can be fully opened.
11. Reposition Ultraviolet Monitor on probe body and tighten set screws.
12. Restore power to the water puri fi er and ultraviolet monitor. If after the cleaning of the quartz rod, there is still no signi fi cant
improvement in the ultraviolet intensity, as shown on the intensity meter, proceed to the “Troubleshooting” section.
