Installation
Section 2 General Information
3.1 UV Disinfection System
CAUTION
Electronic controller must be connected to a Ground Fault Protected Circuit (GFCI) receptacle. Ensure green ground wire
ring terminal is securely fastened to ground stud on UV 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 on top. This is to prevent water dam-
age from occurring on the lamp pins and lamp connector.
•
The controller should be mounted either above or beside the UV chamber. Always mount controller hori-
zontally to prevent moisture from running down cordage and causing a potential fire hazard. Drip loops in
all cordage connected to controller is highly recommended. Refer to 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. Refer to Section 3.2.
•
The disinfection system is intended for indoor use only. DO NOT install disinfection system where it may
be exposed to the weather.
•
Install the disinfection system on cold water line only, before any branched 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.
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 by-pass assembly is recommended in case the system re-
quires "off-line" maintenance. In this case, note the system requires supplementary disinfection for the dis-
tribution 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 two minutes prior to consumption.
