Purenex Multipure Aqua RO System - Manual (Page 24)

NSF/ANSI 58 - Reverse Osmosis
The System has been tested according to NSF/ANSI Standard 58 for the reduction of the following substances. The concen-
tration of the indicated substances in water entering the system was reduced to a concentration less than or equal to the per-
missible limit for water leaving the system, as specified in NSF/ANSI 58.
NOTES:
1. Multipure Drinking Water Systems have been certified, as indicated, by NSF International for compliance to NSF/ANSI Standard
Nos. 42 and 53, and 58.
2. This Multipure Drinking Water System(s) have been certified by the State of California Department of Health Services for the
reduction of specific contaminants listed herein.
3. Chloroform was used as a surrogate for claims of reduction of Volatile Organic Chemicals (VOC). Multipure Systems tested at
>99.8% actual reduction of Chloroform. Percent reduction shown herein reflects the allowable claims for VOCs as per tables in the
Standard.
4. Do not use with water that is microbiologically unsafe or with water of unknown quality without adequate disinfection
before or after the unit. Systems certified for cyst reduction may be used on disinfected waters that may contain fil-
terable cysts.
5. The System may be used with municipal or well water sources that are treated and tested on a regular basis to ensure bacteriolo-
gical safe quality of the water.
6. Do not allow water to freeze in the unit. If unit is exposed to freezing temperatures, drain water from unit and remove filters.
7. Do not allow the RO membrane to dry out. If the RO system is to sit for an extended period of time, remove the RO membrane,
place in a zip lock plastic baggie with a small amount of RO water, and place in the refrigerator until it is time to restart the RO
system. The RO membrane can become damaged if allowed to dry out.
8. Multipure Drinking Water System Housings are warranted for a lifetime (provided that filter has been changed at least once per
year). All exterior hoses and attachments to the System are warranted for defects in material and workmanship for one year. Please
see the Owner’s Manual for complete product guarantee and warranty information.
9. Please see the Owner’s Manual for installation instructions and operating procedures.
10. In compliance with New York law, it is recommended that before purchasing a water treatment system, NY residents have their water
supply tested to determine their actual water treatment needs. Please compare the capabilities of the Multipure unit with your actual
water treatment needs.
11. Check for compliance with state and local laws and regulations.
12. While testing was performed under standard laboratory conditions, actual performance may vary.
13. The list of substances which the treatment device reduces does not necessarily mean that these substances are present in your
tap water.
14. This system is acceptable for treatment of influent concentrations of no more than 27 mg/L nitrate and 3 mg/L nitrite in combination
measured as N and is certified for nitrate/nitrite reduction only for water supplies with a pressure of 280 kPa (40 psig) or greater.
15. 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 0.050 mg/l or less. This system reduces pentavalent arsenic, but may not remove other forms of arsenic.
This system is to be used on water supplies containing a detectable free chlorine residual at the system inlet or on water supplies
that have been demonstrated to contain only pentavalent arsenic. Treatment with chloramine (combined chlorine) is not sufficient to
ensure complete conversion of trivalent arsenic to pentavalent arsenic. Please see the Arsenic Facts section of the Performance
Data Sheet for further information.
