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 0.05
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 50 ppb (0.050 mg/L) 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 below for further information.
Arsenic Facts
Arsenic (As) is a naturally occuring
contaminant found in many ground
waters. Arsenic in water has no color,
taste or odor. It is measured by a
laboratory 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 the state environmental health
agency can provide a list of certified
labs. Information about arsenic in
water can be found on the internet
at the U.S. Environmental Protection
Agency website:
epa.gov/safewater/arsenic
There are two forms of arsenic:
pentavalent arsenic (As(V), As(+5), and
arsenate) and trivalent arsenic (also
called As(III), As(+3), and arsenite).
Although both forms of arsenic are
potentially harmful to human health,
trivalent arsenic is considered more
harmful than pentavalent arsenic. In
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
canprovide this type of service.
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 AQ-SFRO system is designed to
reduce pentavalent arsenic only.
It will not convert trivalent arsenic
to pentavalent arsenic. This System
was tested in a lab. Under testing
conditions, the system reduced
[0.050 mg/L (ppm)] pentavalent
arsenic to 0.010 mg/L (ppm) (the
USEPA standard for drinking water)
or less. The removal performance
of pentavalent arsenic of the system
may be limited due to water quality
conditions (i.e. iron-containing water
or other water quality conditions).
Have your treated water tested for
arsenic to check whether the system
is working properly.
The SmartFlow™ Membrane of the
AQ-SFRO system must be replaced
every 12 months to ensure 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.
Carbon Block and Advanced Carbon Block
Replace every 6 months*
The Carbon and Advanced Carbon Blocks are replaceable activated carbon
cartridges located in Stages 1 and 3. It is recommended to replace these
cartridges at least every 6 months. You may need to replace more often
with high water usage or high sediment levels. Timely replacement of these
cartridges will protect the RO Membrane from high levels of chlorine and/or
sediment. As these filters build up with sediment, you may notice slower
water output.

Advanced Carbon Block replacement manual.
SmartFlow™ Membrane
Replace every 12 months*
The SmartFlow™ Membrane is located in Stage 2. This membrane reduces
the dissolved solids and organic matter. Most municipally treated water has a
7.0-7.5 pH, in this case you would need to replace your SmartFlow™ Membrane
every 12 months. Membrane life depends on pH and supply water hardness.
Higher pH shortens membrane life by causing pin-hole leaks. When output,
water quality, and production rate decrease, it is time to replace the filter.
*Filter life depends on water usage and water supply quality.

Membrane replacement manual.
Remineralizer
Replace every 6 months*
The Remineralizer is located outside of the manifold. It is recommended
to replace this cartridge every 6 months.

Remineralizer replacement manual.
