Signs you need this part

  • The lamp was last changed 12 months ago or more
  • The lamp no longer lights
  • Your system is showing a lamp warning or fault

Why it matters

UV lamps lose output gradually and well before they stop lighting, so they are normally changed every 12 months rather than when they fail.

How to fit it

  1. Isolate power to the UV system and let the lamp cool.
  2. Remove the old lamp following your system manual.
  3. Fit the new lamp, handling it by the end cap and avoiding the glass.
  4. Reconnect the lamp and refit any cover.
  5. Restore power and confirm the system runs normally.
