Installation
Step 1: Th e UV d i s i n f ec t i o n s y s t em s h o u l d al w ay s b e t h e l as t p i ec e o f t r eat m en t b ef o r e t h e
water branches off to the hot and cold water lines if the intent is for Point of Entry (POE) (see figure
2). If the intent for the UV system is for Point of Use (POU) the system should be the final step before the
faucet.
Step 2: US Water Systems strongly recommends that a 5 micron filter be installed before the UV system for
a final polishing step before the water is disinfected.
Step 3: The reactor can be installed either horizontally or vertically using the clamps provided, however
vertical installation is the preferred method with the inlet at the bottom (lamp connection at the top) as it
allows any air that may be in the lines to be easily purged from the system.
Step 4: If the water supply flow rate is unknown, it is recommended that you use a flow restrictor so
that the rated flow of your particular US Water Systems system is not exceeded and the UV dose is not
compromised. The flow restrictor should be installed on the outlet port of the reactor.
Step 5: It is strongly recommended to have a licensed plumber connect the UV reactor to the water sup-
ply and may be a requirement depending on where you are located. If you are attempting this yourself, en-
sure you have all the necessary tools and fittings to accomplish this task.
Step 6: Although there are many methods of installation, this manual will provide a recommended
procedure using copper plumbing and standard soldering methods. US Water Systems recommends the
use of unions, a by-pass assembly and shut-off valves as this will allow you to isolate and remove the UV
reactor if necessary (this method is a recommended method only however it allows for the maximum con-
venience but it requires extra components and more time for installation. Please refer to Figure 3 for the
recommended installation.
Step 7: Before you cut into the cold water line, measure and cut all piping as per the recommended
layout. Once all the components are ready, start by installing the female adapters onto the ports of the re-
actor. To ensure a proper seal, the use of Teflon™ tape is recommended on all threaded connections.
Step 8: Next solder all the assembly together, including ball valves and unions and finally connect-
ed the by-pass assembly to the cold water feed line (water in and water out).
