5. If the water contains any hardness minerals (calcium or magnesium),
iron or manganese, the quartz sleeve will require periodic cleaning. To
remove the quartz sleeve, first remove the UV lamp as outlined in step
1-4. and follow the following steps:
a) Shut off water supply and drain all lines.
b) Remove the lowest connection on the disinfection system and
drain the UV chamber (use a small bucket under the unit to
prevent a spill).
c) Remove aluminum gland nuts from chamber, checking for the
free floating spring inside sleeve at the opposite end to the lamp
connection (do not allow quartz sleeve to fall).
d) Carefully remove 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.
e) Clean the quartz sleeve with a cloth soaked in CLR, vinegar or
some other mild acid and then rinse.
f) 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.
g) Wet the o-rings and slide onto each end of the quartz sleeve and
reassemble the gland nuts (hand tight is sufficient).
h) Re-tighten all connections, turn on water and check for leaks.
I) Re-install the UV lamp and lamp connector as per prior
instructions.
j) Plug in ballast and verify the POWER-ON LED is illuminated and
ballast power-up sequence operates.
Note: If the system is put on a temporary by-pass or if it becomes
contaminated after the disinfection system, it will be necessary to
shock the system with household bleach for a full 20 minutes before
resuming the use of the water.
