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.
INSTALLATIONS IN THE COMMONWEALTH OF MASSACHUSETTS: The Commonwealth of Massachusetts requires installation be
performed by a licensed plumber and does not permit the use of saddle valves. Plumbing code 248—CMR of the Commonwealth of
Massachusetts must be followed in these cases.
Do not use with water that is microbiologically unsafe or of unknown water quality without adequate disinfection before or after the System.
Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts.
Filter is only to be used with cold water. Systems certified for cyst reduction may be used on disinfected water that may contain filterable cysts.

Specifications – Qualified System
Performance
Because the performance of a Reverse
Osmosis Membrane is highly dependent
upon pressure, temperature and Total
Dissolved Solids (TDS), the following should
be used for comparison purposes only.
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.
Measured at 50 psi, 77°±2°F, and 717 mg/l
TDS per NSF/ANSI Standard 58.
Efficiency rating is the percentage of the
influent water to the System that is available
to the user as reverse osmosis treated water.
This measurement is taken under operating
conditions that approximate typical
daily usage.
Recovery rating is 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.

Nitrate/Nitrite Test Kit:
This System is acceptable for treatment
of influent concentration of no more
than 27 mg/L nitrate and 3 mg/L nitrite in
combination measured as N.* 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.
Drain Flow Restrictor
The restrictor is vital for proper operation of
RO Membrane Cartridge as it keeps water
flowing through the membrane at the
proper rate ensuring the water produced
is the best quality. It is recommended the
restrictor assembly be periodically inspected
to be sure it is clean and unrestricted.
If service is required on the drain flow
assembly, disassemble and reassemble as
outlined in Step 5.
Flow rate and output are determined
by 3 factors:
1
Incoming water temperature
2
Total dissolved solids (TDS) present in
supply water
3
Incoming water pressure
Lower temperatures are directly propor-
tional to slower flow rate. All membranes
are tested at 77°F. Incoming water tem-
perature should not exceed 100°F. The RO
Filter System should also not be installed
in a location susceptible to freezing. The
more TDS in the supply water, the more
filter time is required. Incoming TDS should
70 PSI
not exceed 1000 ppm. Higher water pres-
2.5
sure enables a higher flow rate. Pressure
must be above 40 psi for proper system
operation. You may consider installing a
permeate pump or booster pump if your
pressure is below 40 psi.
Carbon Pre-Filter &
Claryum Post-Filter
®
- Change every 6 months*
The Carbon and Claryum filter cartridges
®
are replaceable activated carbon
cartridges located in Stages 1 and 3. It is
recommended replacing these cartridges
at least every 6 months. You may need to
replace more often with high water usage
or high sediment level. 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.
RO Membrane Cartridge
- Change every 12 months
The RO 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 RO
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.
Remineralizer
- Change every 12 months*
The Remineralizer is Stage 4. It is
designed to provide healthy amounts
of calcium, magnesium and potassium
for great-tasting water.
*Filter life depends on water usage and
water supply quality.
