- Remove the lamp.
- Shut off the water supply and drain all lines.
- Remove lowest connection on the disinfection system and drain the UV chameber (use a smell bucket under the unit to prevent a spill) Note: on S12Q-PA and SSM-39 systems, the reactor is provided with a ¼” drain port. On this system simply remove the drain plug and allow water to drain into a bucket.
- Remove aluminum gland nuts from the chamber, checking for the free floating spring inside sleeve at opposite end to the lamp connection (do not allow quartz sleeve to fall).
- Carefully remove the o rings from the quartz sleeve. As the o ring may tend to adhere to the quartz sleeve, it is recommended to replace the O rings annually.
- Clean the outside of the quartz sleeve with a cloth soaked in CLR, vinegar or some other mild acid and then rinse.
- Re-assemble the quartz sleeve with spring in the UV chamber allowing the sleeve to protrude an equal distance from both ends of the UV chamber.
- Wet the o rings and slide onto each end of the quartz sleeve and reassemble the gland nuts (hand tight is sufficient).
- Re-tighten all connections, turn on the water and check for leaks.
- Plug in ballast and verify the POWER-ON LED is illuminated and ballast power-up sequence operates.
