Quartz Sleeve Replacement / Cleaning:
Mineral deposits and sediment may accumulate on the quartz sleeve
decreasing the UV energy required for adequate disinfection. Good
maintenance of filtration equipment will reduce the accumulation of
residues. If necessary, remove the quartz sleeve and clean with a
commercially available scale remover (CLR, Lime-Away, etc.) and a
lint free cloth. Repeat the process as often as necessary to keep the
quartz sleeve clean. Be sure to remove all traces of cleaning fluid from
the sleeve before it is reinstalled in the reactor (be sure not to allow
liquid inside the sleeve).
1. To remove the quartz sleeve, first remove the UV lamp as outlined
in step 1-2 (page 7) then perform 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 gland nuts from both ends of the reactor chamber
(Figure 3A), 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 (Figure 3A).
As the o-ring may tend to adhere to the quartz sleeve, it is
recommended to replace the o-rings annually. Remove quartz
sleeve carefully from chamber.
e) Clean the outside of the quartz sleeve with a cloth soaked in
CLR, vinegar or some other mild acid and then rinse.
f) Re-assemble the quartz sleeve in the UV chamber allowing the
sleeve to protrude an equal distance from both ends of the UV
chamber (Figure 3B).
g) Wet the o-rings and slide onto each end of the quartz sleeve and
reassemble the gland nuts (hand tight is sufficient), slide spring
into quartz sleeve. Use new o-rings supplied.
h) Re-tighten all connections, turn on water slowly and check for
leaks.
i) Re-install the UV lamp and lamp connector as per UV Lamp
Replacement instructions on page 7.
j) Plug in ballast and verify the POWER-ON LED display 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.
