UV Lamp Replacement
1. Disconnect the power.
2. There is no need to disconnect the UV system from the water supply or to drain the water from the reactor
chamber, nor do you need to remove the reactor chamber from the UV system. Lamp replacement is a quick and
simple procedure requiring only a slotted screwdriver to perform the job. After 9,000 hours of continuous
operation (approximately one year), the UV lamp should be replaced.
3. Remove plastic end cover on the UV system. Remove lamp connector from gland nut and carefully slide the UV
lamp slightly out of chamber. Remove the lamp connector from lamp and fully remove lamp (be extremely careful
when handling UV lamp as they are extremely fragile).
4. To install the new lamp, carefully remove from protective tube being careful to handle by the ends only. Do not
touch the glass itself. Slide UV lamp into the reactor chamber. Affix lamp connector to the UV lamp, slide lamp
fully into cell, press fit lamp connector into aluminum gland nut and replace plastic end cover.
5.
Reconnect the power source. Verify “POWER-ON” LED is illuminated and ballast audible start-up sequence operates.
Quartz Sleeve Replacement and/or Cleaning
1. Mineral deposits and sediment may accumulate on the quartz sleeve decreasing UV output. Good maintenance of
filtration equipment will reduce the accumulation of residues. If necessary, remove the quartz sleeve after a few
months and clean with a commercially available scale remover and lint free cloth. Repeat the process as often as
necessary to keep the quartz sleeve clean.
2. 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, 2 & 3 of
the UV lamp replacement instructions above and follow these steps:
A. Shut off water supply and drain all lines.
B. Remove the lower connection on the reactor and drain the UV chamber (use a small bucket under the unit to
prevent a spill).
C. Remove aluminum gland nut 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
recommended to replace the o-rings annually.
E. Clean the quartz sleeve with a lint free cloth and commercially available scale remover and then rinse.
F. Reassemble the quartz sleeve in the UV chamber allowing the sleeve to protrude an equal distance from both
ends of the UV chamber.
G. Lubricate the o-rings with food grade lubricant and slide onto each end of the quartz sleeve and reassemble
the gland nuts (hand tight is sufficient).
H. Retighten all the connections, turn on the water and check for leaks.
I.
Reinstall 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 bypass or if it becomes contaminated after the sterilizer, it will be neces-
sary to sanitize the downstream lines before resuming the use of the water.
