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 entering 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 .
NOTES
Check for compliance with state and local laws and
regulations .
Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after
the system .
For installations in Massachusetts, the Commonwealth of
Massachusetts Plumbing Code 248 CMR shall be adhered
to. Consult your licensed plumber for installation of the
system. This system and its installation must comply with
state and local regulations.
Systems certified for cyst reduction may be used on
disinfected waters that may contain filterable cysts .
Substances that may be 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 this system is 18 .11% .
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 40 .17% . 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 .
Daily Production Rate: 14 .66 gpd
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±10 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 .

Arsenic Fact Sheet
Arsenic (abbreviated As) is found naturally in some well
water . Arsenic in water has no color, taste or odor . It must
be measured by a lab test . Public water utilities must have
their water tested for arsenic . You can get the results from
your water utility . If you have your own well, you can have
the water tested . The local health department or state
environmental health agency can provide a list of certified
labs . There are two forms of arsenic: pentavalent arsenic
[also called As(V), As(+5), and arsenate] and trivalent arsenic
[also called As(III), As(+3) and arsenite] . In well water,
arsenic may be pentavalent, trivalent, or a combination of
both . Special sampling procedures are needed for a lab to
determine what type and how much of each type of arsenic
is in the water . Check with the labs in your area to see if
they can provide this type of service . Reverse osmosis (RO)
water treatment systems do not remove trivalent arsenic
from water very well . RO systems are very effective at
removing pentavalent arsenic . A free chlorine residual will
rapidly convert trivalent arsenic to pentavalent arsenic .
Other water treatment chemicals such as ozone and
potassium permanganate will also change trivalent arsenic
to pentavalent arsenic . A combined chlorine residual (also
called chloramine) may not convert all the trivalent arsenic .
If you get your water from a public water utility, contact the
utility to find out if free chlorine or combined chlorine is
used in the water system . The system is designed to remove
pentavalent arsenic . It will not convert trivalent arsenic to
pentavalent arsenic . The system was tested in a lab . Under
those conditions, the system reduced 0 .30 mg/L (ppm)
pentavalent arsenic to 0 .010 mg/L (ppm)(the USEPA standard
for drinking water) or less . The performance of the system
may be different at your installation . Have the treated water
tested for arsenic to check if the system is working properly .
The RO component of the system must be replaced every
12-24 months to ensure the system will continue to remove
pentavalent arsenic . The component identification and
locations where you can purchase the component are listed in
the installation/operation manual .
