RO 50 (P/N 01038040)
Aquasential RO Drinking Water Systems with RO 50 have been tested according to CSA B483�1, NSF/ANSI 372, and
NSF/ANSI 58 for the reduction of the substances listed below� The concentration of the indicated substances in water
entering the systems were reduced to a concentration less than or equal to the permissible limit for water leaving the
systems, as specified in NSF/ANSI 58�
These systems are 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 are certified for nitrate/nitrite reduction only for water supplies with a pressure of 280
kPa (40 psig) or greater�

1 While testing was performed under standard laboratory conditions, actual performance may vary depending on water pressure, temperatures and other
substances, which may be found in your water�
2 Thes systems have 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� These systems reduce pentavalent arsenic, but may not remove other forms of arsenic� These systems are 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 chloramines (combined chlorine) is not sufficient to ensure complete conversion of trivalent arsenic to pentavalent arsenic� Please
see the Arsenic Facts Sheet for further information�
3 Based upon testing methods using Barium as a surrogate� All concentrations in pCi/L pico curie/L�
4 Includes Giardia lamblia, Entamoeba histolyca and Cryptosporidium�
5 Units are not certified on water supplies with a pressure less than 40 psi (280 kPa)� A booster pump is strongly recommended�
