PLUMBING SYSTEM DISINFECTION PROCEDURE
THE FOLLOWING DISINFECTION PROCEDURE IS GENERALLY ACCEPTED
AS BEING SUITABLE FOR THE DISINFECTION OF PLUMBING SYSTEMS
KNOWN TO BE CONTAMINATED.
IF YOU ARE UNCERTAIN ABOUT THE EFFECTIVENESS OF THIS
PROCEDURE YOU ARE ADVISED TO CONTACT YOUR LOCAL HEALTH
AUTHORITY RESPONSIBLE FOR WATER SAFETY.
During the UV disinfection process the only place disinfection takes place is within
the reactor chamber. There is no residual disinfectant capacity. Therefore, it is
necessary to chemically disinfect the plumbing system prior to the initialization of
the UV system.
1. Turn the UV system shut off valves to the closed position.
2. The disinfection of the plumbing system is most readily accomplished by
removing the 5-micron pre-filter cartridge and adding 250-500ml (1-2 cups) of a
standard 5% concentration of unscented household bleach into the empty filter
housing and re-attaching.
3. Verify that the UV system is connected to the AC power voltage and operating
properly.
