PERFORMANCE DATA
IMPORTANT:
Read this performance data and compare the capabilities of
this system with your actual water treatment needs.
It is recommended that before installing a water treatment
system, you have your water supply tested to determine your
actual water treatment needs.
This system has been tested according to NSF/ANSI 58 for the
reduction of substances listed below. The concentration of the
indicated substances in water enteringthe sysem was reduced
to a concentration less than or equal to the permissible limit
for water leaving the system as specified in NSF/ANSI 58.
The GRO-475BP shall only be used for arsenic reduction on
chlorinated water supplies containing detectable residual free
chlorine at the system inlet. Water systems using an in-line
chlorinator should provide a one-minute chlorine contact time
before the RO system.
Do not use with water that is microbiologically
WARNING:
unsafe or of unknown quality without adequate disinfection
before or after the system. Systems certified for cyst reduction
may be used on disinfected waters that may contain filterable
cysts.
NOTE: Substances reduced are not necessarily in your water.
Filter must be maintained according to manufacturer's
instructions, including replacement of filter cartridges.
The tested efficiency rating for these systems is 51.42%.
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.
The tested recovery rating is 55.82%. Recovery rating means
the percentage of the influent water to the membrane portion
of the system 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.
The GRO-475BP 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 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.

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.
