OPERATING AND MAINTENANCE INSTRUCTIONS
NOTE: Prior to performing any work on the Ultraviolet Light System, always disconnect the power supply fi rst
1) Regularly inspect your Ultraviolet Light System to ensure that the UV lamp is operating.
2) Replace the UV lamp with a new lamp after one year of continuous use to ensure a high bacteria and virus kill rate.
It should be noted that the UV lamp should be ON continuously as repeatedly turning the lamp on and off will severely
shorten the lamp life and allow bacteria to pass through without being affected by the UV.
3) To replace the UV lamp, fi rst disconnect power. Disconnect the lamp connector by carefully separating it from the
gland nut (use the aid of a slot screwdriver if required). Disconnect lamp connector from lamp and carefully remove the
UV lamp. Replace the new lamp being careful not to touch the new UV lamp “glass” with your fi ngers as oils impair UV
transmission. If contact does occur, clean with alcohol and reconnect carefully replace lamp into stainless steel cell. Press
lamp connector into aluminum gland nut. Plug power source into outlet. Verify “POWER-ON LED” is illuminated and ballast
audible start-up sequence operates.
4) 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, fi rst remove the UV lamp as outlined in step 3 and follow the following steps:
A) Shut off water supply and drain all lines.
B) Remove the lower connection on the Ultraviolet Light System and drain the UV chamber (use a small bucket under
the unit to prevent a spill).
C) Remove aluminum gland unit from chamber. (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 recom-
mended to replace the o-rings annually.
E) Clean the quartz sleeve with a cloth soaked in 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.
G) Wet the o-rings and slide onto each end of the quartz sleeve and re-assemble the gland nuts (hand tight
is suffi cient).
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 Ultraviolet Light System, it will
be necessary to shock the system with household bleach for a full 20 minutes before resuming the use of the water.

Note: If the ballast enters alarm condition, power must be removed for 30 seconds to allow ballast to reset.
Note: As the system requires time to reach its full operating capacity, please allow the Ultraviolet Light System to
operate 3-5 minutes prior to using the water from the unit. In addition, to clear any air from the system, open the
faucet and allow water to run through the Ultraviolet Light System for 2-3 minutes (when using an RO application,
run the water for 30-45 seconds).
