Specications – Qualied System erformance
Because the performance of a Reverse Osmosis Membrane is highly dependent upon pressure,
temperature and TDS, the following should be used for comparison purposes only.
1. ndustry standards measure RO Membranes performance with no back pressure on the product water,
at 60 psig (414kPa) 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 gures 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/ANS Standard 58.
3. Efficiency rating means the percentage of the inuent 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 inuent 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 adequate disinfection
before or after the system. This system is certied for cyst reduction and may be used on disinfected water
that may contain lterable 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.
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
followed in these cases.
The product water shall be tested periodically to verify the system is performing satisfactorily.
roduct 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 18 months, or more often based on your local water. Only
replace the reverse osmosis membrane with a part approved for use in your Reverse Osmosis system.

SYSTEM MAINTENANCE
relter/ ostlter
The pre-lters (sediment- stage 1 and carbon - stage 2) and post-lter (carbon - stage 4) are replaceable
cartridges, and it is recommended replacing these every 6 months. You may need to replace more often
with high water usage or high sediment level. Replacing these cartridges timely will protect the RO
membrane from high levels of chlorine and/or sediment. As these lters build up with sediment, you may
notice slower water output.
RO Membrane Cartridge
The RO membrane is located in stage 3. This membrane is a tightly wound membrane which reduces the
dissolved solids and organic matter. Cartridge 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 membrane cartridge, typically after 24 months.
Flow rate and output are determined by 3 factors:
1 ncoming water temperature
2 Total dissolved solids (TDS) present in supply water
3 ncoming water pressure
Lower temperatures are directly proportional to slower ow rate. All membranes are tested at 77°F.
ncoming water temperature 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, greater lter time is required. ncoming TDS should not exceed 1000 ppm.
Higher water pressure enables a higher ow 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.
RO Cartridge Replacement
1 Remove the pre-lter cartridges rst to relieve pressure on the RO lter.
2 Turn RO lter to left and remove.
3 Remove post-lter cartridge.
4 Discard cartridges.
5 nstall new cartridges in reverse order turning to the right to secure:
a – Post-lter (stage 4)
b – RO membrane (stage 3)
c – Pre-lter (stage 2)
d – Pre-lter (stage 1)
6 Purge RO Filter System as outlined in Step Eight.
13

re-Filter & ost-Filter Cartridge Replacement
1 Remove pre-lter cartridge by turning to the left.
2 Remove post-lter cartridge by turning to the left.
3 Discard cartridges.
4 nstall new cartridges in reverse order by turning to the right:
a – post-lter
b – pre-lters
5 Purge RO Filter System as outline in Step Eight.
Drain Flow Restrictor
The restrictor is vital for proper operation of the RO membrane cartridge as it keeps water owing through
the membrane at the proper rate ensuring the water produced is the best quality. t is recommended the
restrictor assembly be periodically inspected to be sure it is clean and unrestricted. f service is required on
the drain ow assembly, disassemble and reassemble as outlined in Step Six.
