Non-potable Water Sources: Do not attempt to use this product to make safe drinking water from non-potable water sources. Do not use the system on microbiologically unsafe water, or water of
unknown quality without adequate disinfection before or after the system. This system is certified for cyst reduction and may be used on disinfected water that may contain filterable cysts.
Arsenic Reduction: This system shall only be used for arsenic reduction on chlorinated water supplies containing detectable residual free chlorine at the system inlet. Water systems using an inline
chlorinator should provide a one minute chlorine contact time before the reverse osmosis system.
Nitrate/Nitrite Test Kit: This system is acceptable for treatment for influent concentrations of no more than 27mg/L nitrate and 3mg/L nitrite in combination measured as N. It is certified for nitrate/nitrite
reduction only for water supplies with a pressure of 280 kPa (40 psig) or greater. This system is supplied with a nitrate/nitrite test kit. Product water should be monitored periodically according to the
instructions provided with the test kit.
Product Water Testing: The Reverse Osmosis System contains a replaceable membrane cartridge critical for the effective reduction of total dissolved solids (TDS).
Replacement of the reverse osmosis membrane cartridge: The reverse osmosis system contains a replaceable membrane cartridge critical to the efficiency of the system. This membrane should be
replaced every 12 months, or more often based on your local water. Only replace the reverse osmosis membrane with a part approved for use in your DuPont Reverse Osmosis system.

1 Industry standards measure RO Membranes performance with no back pressure
on the product water, at 60 psig (414 kPa) and 77°F (25°C). Further conditions on
the above are 250 ppm TDS and a 30.6% recovery rate. Production rate and TDS
reduction figures are for a new Membrane that has been rinsed for 24 hours.
The production rate of a new Membrane can decrease by 10% per year or more,
depending upon the scaling and fouling tendencies of the Feed Water.
2 Measured at 50 psi, 77° ± 2°F, and 717 mg/l TDS per NSF/ANSI Standard 58.
3 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.
4 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.
