If after cleaning the quartz sleeve, there is no significant 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
fitting, located in the center of the disinfection chamber, and protrudes into the chamber.
1.
Disconnect power to the water purifier.
2.
Shut off water supply to the water purifier 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 Teflon ® thread sealing tape, reinstall and tighten the drain plug.
3.
Disconnect power to the Ultraviolet Monitor; remove from chamber by loosening the two setscrews 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 retainer 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 fingerprints 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-ring, quartz rod and securing in place with the quartz rod-retaining cap. Tighten
the quartz rod-retaining cap by hand only, DO NOT USE HAND TOOLS. Tightening with hand tools my
damage the quartz rod or o-ring seal.
9.
Reinstall sensor probe into the center fitting of the chamber and tighten.
10.
Slowly restore water supply to the water purifier, 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 setscrews.
12.
Restore power to the water purifier and ultraviolet monitor.
If after the cleaning of the sensor quartz rod, there is still no significant improvement in the ultraviolet
intensity, as shown on the intensity meter, proceed to the "Troubleshooting" section.
