Introduction
The Watts SmartStream
line of ultraviolet disinfection systems
™
provide protection against microbiological contamination in water for
residential and commercial applications.
Disinfection of water with SmartStream
process. When contaminated water is exposed to SmartStream's
254 nanometer UV light, the UV light penetrates the cell walls of
microorganisms and disrupts their genetic deoxyribonucleic acid
(DNA) material. This quickly inactivates microorganisms by destroy-
ing their ability to replicate and infect.

at anytime a component needs to be replaced,
use only parts recommended and supplied
by Watts. DO NOT add components to or
remove components from this system.
The UV lamp is rated for 9000 hours under
normal operating conditions and should be
replaced annually to keep the UV intensity at
the highest possible output. Quartz sleeves
should be cleaned as needed or replaced as
needed to guarantee the highest possible UV
transmittance into the water.
Use only Watts supplied UV lamps and quartz
sleeves for your specific model. Failure to do
so may result in system failure and will void all
