Cleaning and Replacing Quartz Sleeve
Note: Minerals in the water slowly form a coating on the quartz sleeve. This coating must be removed because
it reduces the amount of UV light reaching the water, thereby reducing disinfection performance. If the sleeve
cannot be cleaned, it must be replaced.
Prerequisites:
Shut off water supply and drain the line.
Place a small pail under the unit to catch any spills.
Remove the UV lamp.
Refer to Previous Section.
Remove the bottom retaining nut,
floating spring, and Oring.
Remove the top retaining nut and
O-ring.
Carefully remove O-ring adhering
to the sleeve. Remove the quartz
sleeve.
Clean the quartz sleeve with a
cloth soaked in CLR, vinegar or
some other mild acid and then
rinse with water.
Note: If sleeve cannot be
completely cleaned or it is
scratched or cracked, then replace
the sleeve.
Reinstall the quartz sleeve in the
UV chamber allowing the sleeve
to protrude at equal distance on
both ends of the UV chamber.
Reinstall the top and bottom
retaining nuts, floating spring, and
O-rings respectively.
When service is complete,
assemble the prerequisites in the
reverse order of disassembly.
Push the lamp connector against
lamp connector base together until
an audible click is heard.
Plug in controller and verify the
POWER-ON LED display is
illuminated.
Re-pressurize the system to check
for leaks.
Notes:
1) After replacing the UV lamp or
quartz sleeve, perform the disinfection
procedure.
2) If the system is put on a temporary
by-pass or if it becomes contaminated
after the disinfection system, it is
necessary to shock the system with
household bleach for a full 20 minutes
before resuming the use of the water.
