Section 3 Installation
3.1 Installing UV 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.
If installing the chamber in horizontal position the outlet port must be pointing upwards to ensure all air is fully purged from
the chamber.
Note: The ideal installation is vertical with the lamp connector on top. This is to prevent water damage from occurring on the
lamp pins and lamp connector.
9Flow Restrictor
Restricts water from flowing over the maximum NSF certified flow rate ensuring an adequate UV dose
is maintained.
10 Sample valve
Allows for sampling of water immediately following UV treatment; necessary in order to confirm
proper operation of UV system.
11 Shut-off valve Required to allow maintenance of UV system.
12 Controller
Powers and controls the UV lamp and other devices. Provides human interface, displaying
information and allowing control inputs (such as muting the audible alarm).
13 Power source
Provides power to the controller. For safety reasons the outlet must be protected by a Ground Fault
Circuit Interrupter (GFCI).
Note: To protect the controller, a UL1449 certified (or equivalent) transient voltage surge suppressor is
required.
