1
A pressure regulator is recommended for feed water pressures exceeding 80 psig (552 kPa)
2
See the Technical Manual for all applications where TDS exceeds 1000 ppm (1000 mg/L) to calculate
effective module pressure. A booster pump is strongly recommended.
3
The reverse osmosis membrane filter used in this system may be damaged by chlorine. This system
includes activated carbon which protects this element by reducing chlorine. Influent chlorine should not
exceed 2 mg/L.
4
Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfec-
tion before or after the system.
Certified Performance
System Tested and Certified by NSF International against ANSI/NSF Standard 58
for the reduction of: Barium, Cadmium, Copper, Fluoride, Hexavalent Chromium,
Lead, Radium 226/228*, Selenium, Total Dissolved Solids, Trivalent Chromium,
Cysts, and Turbidity
The substances removed by this system are not necessarily in your untreated water. See
Performance Data Sheet for percentages of contaminant removal.
* Minimum removal based on approved testing methods with Barium as surrogate.
