Disinfecting Your Water System
In any UV system, disinfection takes place inside the UV chamber and there is no
residual disinfection agent remaining in the water stream. Pathogens that may still
be present in the plumbing system downstream of the UV unit will not be affected
by the disinfection process. For this reason, it is CRITICAL that the plumbing
system is disinfected after initial installation to prevent possible re-contamination
of the water on it’s way to the taps.
The following steps must be taken to accomplish this important task.
1 Turn off the water supply to the UV unit and make sure that the by-pass valve is
closed if equipped. Turn on the UV unit.
2
Remove the filter bowls from the filter housing head and remove the filter car
-
tridges.
3
Fill one filter bowl one-half full with chlorine bleach and screw the bowls (without
cartridges) back onto the filter housing head.
4 Turn on the water supply, check for leaks.
5 Turn on every tap in the water system of the building both inside and outside,
one-by-one. Run the water at each tap until the smell of chlorine is evident. Let
the system sit idle for 60 minutes.
6
While the UV lamp remains on, open all taps in the water system to flush out the
chlorine - approximately 5 minutes.
7
When all chlorine is flushed from the system, and while the UV lamp remains on,
shut off the water supply and reinstall the filter cartridges in the filter housings.
8 Turn on the water supply, check for leaks. Test water for contaminants.
WARNING
This simple procedure must be performed after installation
of the UV system, and whenever the UV system is shut down
or inoperative for any reason whatsoever.
