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 cal-
culate 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 sys-
tem 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
disinfection before or after the system.
Certified Performance
System Tested and Certified by NSF International against NSF/ANSI Standard 58 for the
reduction of: Arsenic (Pentavalent), Barium, Cadmium, Copper, Fluoride, Hexavalent
Chromium, Lead, Radium 226/228*, Selenium, Total Dissolved Solids, Trivalent
Chromium, Cysts, and Turbidity
The Culligan Water Tower™ conforms to NSF/ANSI 58 for pentavalent arsenic reduction. See per-
formance data sheet and arsenic facts section for an explanation of reduction performance.
The substances removed by this system are not necessarily in your untreated water. See
Performance Data Sheet for percentages of contaminant removal.
This system has been tested for the treatment of water containing pentavalent arsenic (also known
as As(V), As(+5), or arsenate) at concentrations of 0.30 mg/L or less. This system reduces pentava-
lent arsenic , but may not remove other forms of arsenic. This system is to be used on water sup-
plies containing a detectable free chlorine residual or on water supplies that have been demonstrat-
ed to contain only pentavalent arsenic. Treatment with chloramine (combined chlorine) is not suffi-
cient to ensure complete conversion of trivalent arsenic to pentavalent arsenic. Please see the
arsenic facts section of the performance data sheet of further information.
* Minimum removal based on approved testing methods with Barium as surrogate.
