Feed Water Requirements
Please review operating pressures, temperatures and water
chemistry limitations to ensure compatibility.
Installation
1. Remove all system components from packaging and
inspect for any damage. Confirm that the system being
installed matches the flow rate for the application.
2. Turn off water heater(s).
3. Turn off the main water supply valve to the pipe the system
will be installed in.
4. Relieve pressure within plumbing system by opening then
closing both the hot and cold sides of a faucet until water
ceases to dispense from faucet.
5. If equipped with isolation valves, isolate the water heater(s)
by closing its inlet and outlet valves.
6. Mount the UV system on its installation surface using
appropriate hardware for your mounting surface type. The
system comes with 1" wood screws for mounting to wooden
surfaces. If system is being mounted to anything other than
wood then the installer must provide the appropriate mount-
ing hardware. The mounting surface and hardware must be
sturdy enough to support the weight of the wetted system.
7. Connect the water supply pipe to the inlet of the UV system.
8. Install a supply valve in this supply line.
9. Install an adequately sized 5 micron cartridge filter in this
supply line after the supply valve. The cartridge filter must
have a higher flow rate rating than the UV system.
10. Connect the outlet of the system to the outlet plumbing.
11. Install the solenoid safety shut off valve in this outlet plumb-
ing line (optional).
12. Install a flow controller in this outlet plumbing line after the
solenoid valve (optional).
13. Install an outlet valve in this outlet plumbing line. This valve
should be located after any optional devices such as the
solenoid valve or flow control.
14*. Install the quartz sleeve into the UV chamber. DO NOT touch
the quartz sleeve with your fingers. Hold it with a paper towel.
15*. Install the quartz sleeve o-ring onto the visible end of the
quartz sleeve. Screw the quartz sleeve nut onto the quartz
sleeve port thread and tighten hand tight.
16*. Install the ultraviolet lamp into the quartz sleeve. DO NOT
touch the lamp with your fingers. Hold it with a paper towel.
17*. Insert the lamp power lead wire into the receptacle on the
lamp's glow cap.
18**. If using the solenoid valve safety shut off feature, connect
the solenoid valve's power wires to the solenoid valve
power output on UV system controller. Then plug the sole-
noid valve transformer into a power outlet. Use only Watts
supplied solenoid valve kit part number T7401001 for 20
GPM systems and below and part T7401002 for 25 GPM
systems and above.
19. Open water supply valves.
20. Check for leaks and repair as needed.
21. Plug in power cord.
22. Open outlet valve.
23. Purge air from plumbing system out of the nearest cold
water faucet to the UV system.
24. Open inlet and outlet isolation valves on water heaters(s)
and turn water heaters back on.
25. Perform the sterilization procedure within this manual.
