Performance Data Sheet - PUR PUN3RO Manuel Du Propriétaire

Performance Data Sheet:

Reverse Osmosis Drinking Water System
Model: PUN3RO and PUN4RO
The system must be installed and operated in accordance with manufacturer's recommended procedures and guidelines.
Failure to follow the instructions may result in leakage, malfunction and will void warranty.
Read the performance data (on page 16) and compare the capability of the system with your actual water treatment needs. It
is recommended that, before installing the system, you have your water supply tested to determine your actual water treatment
needs.
Arsenic Fact Sheet
This system has been tested for the treatment of water containing pentavalent arsenic (also known as As(V), As(+5) or Arsenate)
at concentration of 0.30 mg/L or less. The systems reduce pentavalent arsenic, but may not reduce other forms of arsenic. These
systems are also to be used on the 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.
Arsenic is a naturally occurring contaminant found in many ground waters. There are two forms of arsenic: Pentavalent Arsenic
[also called as As(V), As(+5) or Arsenate] and Trivalent Arsenic [As (III), As (+3) and Arsenite]. Although both forms are potentially
harmful to human health, trivalent arsenic is considered more harmful than pentavalent arsenic.
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.
RO systems do not remove trivalent arsenic from water very well. RO systems are very effective at reducing pentavalent arsenic. If
you have free chlorine residual in contact with your water supply for at least one minute, the trivalent arsenic will be converted to
pentavalent arsenic and reduced by RO systems. 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 requires regular replacement of all filters to maintain proper operation. Depending on usage and influent water quality,
the sediment and carbon filters should be changed at least annually and the RO Membrane should be replaced every 2 years.
Variation of chlorine, sediment or TDS levels may affect replacement frequency.
