Section 3 Installation
3.1 UV Disinfection System
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: Install vertically with the lamp connector on top to prevent water damage from occurring on the lamp pins and lamp
connector.
• The controller should be mounted either above or beside the chamber. Always mount controller horizontally to prevent
moisture from running down cordage and causing a potential fire hazard. (Figure 5)
• 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. (Section 3.2)
• For indoor use only.
• Install the disinfection system on cold water line only, before any branched lines.
• A 5 micron sediment filter must precede the disinfection system. System should be the last treatment the water
receives before it reaches the faucet.
Procedure:
1. (Figure 2) shows the installation of a typical disinfection system and the related components that may be used for the
installation. The use of a bypass assembly is recommended in case the system requires offline maintenance. In this
case, note that the system requires a supplementary disinfection for the distribution system if any water is used during
by-pass condition. In addition, during by-pass, the water will NOT be disinfected and a “DO NOT CONSUME THE
WATER” tag should be physically installed on the by-pass assembly until such time as the system is sanitized and
returned to service. For more information, refer to Section 3.2. If the water is to be consumed while the system is off-
line, the water must be boiled for twenty minutes prior to consumption.
CAUTION
Electronic controller must be connected to a Ground Fault Protected Circuit (GFCI) receptacle and the lamp connector ground wire connected to the
stainless steel chamber.
