The quartz sleeve can be coated in limescale build up in hard water areas.
This should be carefully removed from the quartz sleeve and cleaned with a
soft damp cloth.
Use a flathead screwdriver to separate the quartz glass from the UV case
and remove the quartz by pulling it out (CUV-207 / 209 and 211 models only).
Unscrew the clamp screw and gently remove the UV quartz from the ballast
(CUV-218 / 224 / 236 and 272 models only).
Clean body and all attachments. Reassemble.

When reassembling your unit you must replace all O-rings as
per the parts diagram as otherwise this can cause the unit to leak which will
cause permanent damage to the UV operation.
Common Reassembly Questions
CUV-207 / 209 / 211
- when reassembling your unit you must make sure the
black O-ring sits on top of the quartz sleeve as seen in the image below.
Close the unit with the ballast pointing downwards. This is to ensure the O-
ring doesn’t fall out of place and enables you to correctly close the unit.
