Performance Data Sheet
System Performance
This system has been tested according to NSF/ANSI 58 for reduction of the substances listed below. The concentration of
the indicated substances in water leaving the system was reduced to a concentration less than or equal to the permissible
limit for water leaving the system, as specified in NSF/ANSI 58. Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after the system. Systems certified for cyst reduction may be used
on disinfected water that may contain filterable cysts.
This system has been tested for the treatment of water containing pentavalent arsenic (also known as AS(V), As
+5
, or ar-
senate) at concentrations of 50 ppb. This system reduces pentavalent arsenic, but may not reduce other forms of arsenic.
This system is to be used on water supplies containing a detectable free chlorine residual at the system outlet 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 sec
-
tion of the Performance Data Sheet for further information.
Testing was performed under standard laboratory conditions, actual performance may vary. Incoming water must be free of
potential membrane foulants such as Iron, Hydrogen Sulfide and Manganese. Efficiency rating means the percentage of the
influent water to the system that is available to the user as reverse osmosis treated water under operating conditions that
approximate typical daily usage. Recovery rating means the percentage of the influent water that is available to the user as
reverse osmosis treated water when the system is operated without a storage tank or when the storage tank is bypassed.

System Maintenance
This reverse osmosis system contains a replaceable component critical to the efficiency of the system. Replacement of the
reverse osmosis component should be with one of identical specifications, as defined by the manufacturer, to ensure the
same efficiency and contaminant reduction performance. See: http://nimbuswater.com/techinfo/wm5_manual.pdf.
