1. ABOUT THE HALLETT  
The Upstream and the Hallett systems, manufactured by UV Pure Technologies, 
are the world’s only ultraviolet water purification device with patented Crossfire 
Technology. 
Patented in US 6,707,048, Canada 2,463,503, Australia 2,002,333,084, 
Mexico 248805 
Patent Pending in Japan, UK, Europe, & Eurasia 
UV Pure’s Hallett UV systems employ revolutionary Crossfire Technology that is 
self-cleaning, self-monitoring, and fail-safe. The Hallett
®
 system with Crossfire 
Technology®  is designed to eliminate the potential risks associated with 
conventional single lamp UV systems. 
Committed to exceeding drinking water purification standards, UV Pure has 
turned conventional technology inside-out by running the water inside the quartz 
sleeve and including two lamps mounted in air, dual smart sensors, elliptical 
reflectors and an optional fail-safe solenoid valve. 
Crossfire Technology is complete UV disinfection: Crossfire Technology 
incorporates two proprietary high-output UV lamps, with elliptical reflectors, that 
target pathogens with radiation from 360º, to deactivate pathogens and provide 
microbiologically safe drinking water. 
Crossfire Technology is engineered to be risk-free and fail-safe: Crossfire 
Technology uses dual smart UV sensors mounted in air, which are designed to 
not foul and are more reliable indicators of system performance than ordinary 
systems. The lamps are fan-cooled and maintain consistent levels of UV output 
for maximum pathogen deactivation. Computerized alarms and an auto shut-off 
fail-safe valve are designed so that only safe water can enter your water system. 
Each system shipped to the North American market is supplied with a Transient 
Voltage Surge Suppressor (TVSS)/Surge Protective Device (SPD) that has been 
certified to the UL 1449 standard by an NRTL/C and includes integral 
Over/Under Voltage shutoff protection. 
Crossfire Technology is self-cleaning: Crossfire Technology uses a stainless 
steel wiper to clean the inside of the quartz sleeve eliminating quartz fouling and 
the need for a water softener making abrasive quartz cleaning a thing of the past 
– saving money and the environment. 
Crossfire Technology is virtually maintenance-free: Crossfire technology 
utilizes two lamps mounted in air, outside the quartz sleeve so maintaining a 
Hallett is as easy as changing a light bulb with no system draining required. The 
UV lamps require replacement after 12 months of operation and notification of 
lamp replacement is given via a warning one month in advance. 
Crossfire Technology is easy to install: Crossfire technology employs flexible 
stainless steel hoses with Female Iron Pipe (FIP) connections for quick and 
simple installation.
