UV is environmentally and user friendly, with no dangerous chemicals to handle or store. UV treatment does not change the taste, odor, pH, or the general chemistry of water. Simple and easy to maintain with only a periodic cleaning of sleeve and annual lamp replacement. Please dispose of UV lamps in accordance of local and state regulations.

  • Specific unit 0-rings should be replaced every time a quartz sleeve is cleaned or replaced
  • When replacing O-ring handle quartz sleeve carefully to prevent breaking or chipping
  • Install O-ring down the top of the nipple on the quartz sleeve
  • Proper positioning is critical to provide seal
