  1. The UV Clarifier brings UltraViolet radiation when it is working, which is harmful to the human eyes & skin. Avoid eye contact and skin contact with the UV light at all times. Remember to switch off the power before opening the unit.
  2. The working status of the UV lamp can be observed from a small eliptical white lens on the unit.*
  3. When the unit is damaged (ie. dropped or slightly bumped) please check to see that there is no damage to the quartz tube and UV lamp. If any damage has occured, the unit cannot be used until the broken parts have been replaced.

*NOTE: The lens from the unit is normally brighter when the unit is first used. Over time, the light may dim some. This is a result of dirt particles blocking the lens. The lens can be cleaned by opening the unit, however, be sure to TURN THE UNIT OFF before opening it.

It is suggested that this clarifier be used with a pump no stronger than 1050 GPH.

  2. Place the O-ring on the inlet/outlet and screw on the two screws on the water inlet/outlet tightly.
