This system conforms to NSF/ANSI 58 for the specific performance claims as verified and substantiated by test data.
1
@ Feed water supply at 50 psi, 77°F, and 750 TDS --- Quality water production, amount of waste water and percent rejection all vary with
changes in pressure, temperature and total dissolved solids.
2
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.
3
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.
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 an 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 chlo-
rine 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 of 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.
TDS Test Kits: TDS test kits are available by calling 1--800--949--8220 or check the water testing section of your local phone directory.
Installations In The Commonwealth Of Massachusetts: The Commonwealth of Massachusetts requires installation be performed by a
licensed plumber and do not permit the use of saddle valves. Plumbing code 248--CMR of the Commonwealth of Massachusetts must be fol-
lowed in these cases.
Product Water Testing: The Reverse Osmosis System contains a replaceable treatment component critical for the effective reduction of total
dissolved solids. Product water should be tested periodically to verify that the system is performing properly.
Replacement of the reverse osmosis component: 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
assure the same efficiency and contaminant performance.
