The water and UV system are under pressure. Before performing any maintenance on the system, in particular, removing the lamp and/or sleeve, you must:

  • Disconnect the power.
  • Turn off the water supply upstream of the UV system.
  • Release water pressure before servicing by opening a downstream faucet.
  • Ensure there is no closed valve between the open faucet and the UV system.
  • After relieving the pressure, proceed with replacing the lamp, cleaning the sensor, and/or cleaning or replacing the sleeve.

Failure to follow these instructions can result in UV exposure, severe bodily injury, or death due to the forcible ejection of a quartz sleeve, lamp, broken glass, or other material from the chamber.
