Conditions For Use
Water quality is extremely important for the optimum performance of your UV system. The following levels are recommend-
ed for installation:
If your water chemistry contains levels in excess of those mentioned above, proper pre-treatment is recommended to cor-
rect these water problems prior to the installation of your UV disinfection system. These water quality parameters can be
tested by your local dealer, or by most private analytical laboratories.
Proper pre-treatment is essential for the UV dis-
infection system to operate as intended.
Installing Your UV Disinfection System
CAUTION
Electronic ballast must be connected to a grounded receptacle and the lamp connector ground wire connected to the stain-
less steel reactor chamber.
• The disinfection system is designed to be mounted either horizontally or vertically at the point-of-use or point-of-entry
depending on the specific flow rate of the unit.
Note: The ideal installation is vertical with the lamp connector at the top. This is to prevent water damage from occur-
ring on the lamp pins and lamp connector.
• The ballast should be mounted either above or beside the reactor chamber. Never mount vertically with AC connector
at top of ballast to prevent moisture from running down cordage and causing a potential fire hazard. Drip loops in all
cordage connected to ballast controller is highly recommended (see Figure 1D).
• The complete water system, including any pressure or hot water tanks, must be sterilized before start up by flushing
with chlorine (household bleach) to destroy any residual contamination (see page 4).
• For safety purposes, the disinfection system should be connected to a ground fault interrupt circuit.
• The disinfection system is intended for indoor use only, do not install disinfection system where it may be exposed to
the outdoor weather.
• Install the disinfection system on cold water line only.
• If treating the entire house, install the disinfection system before any branch lines.
• A 5 micron sediment filter must precede the disinfection system. Ideally, the disinfection system should be the last
treatment the water receives before it reaches the faucet.

Note: The UV lamp inside the disinfection system is rated at an effective life of approximately 9000 hours. To
ensure continuous protection, replace the UV lamp annually.
Typical Installation

Iron (Fe)
< 0.3 ppm (0.3 mg/L)
Hardness*
< 7 gpg (120 mg/L)

*Where total hardness is less than 7 gpg, the UV unit should operate efficiently provided the quartz
sleeve is cleaned periodically. If total hardness exceeds 7 gpg, the water should be softened.
