Tips for Long Membrane Life
1. Replacement of 1 micron sediment filter once every 6 months.
This will prevent membrane fouling due to silt or sediment
depositing on the membrane.
2. Replacement of 10 micron carbon block filter at least once
every 6 months or when chlorine breakthrough occurs . This
will ensure good membrane life and prevent membrane from
chlorine damage.
3. Membrane should not be operated at lower than 4:1
concentrate to purified water ratios. If you have a lower ratio,
reduce the length of the flow restrictor to adjust the ratio
to 4:1.
4. Operating reverse osmosis systems on softened feed water
greatly reduces the chances of membrane fouling.
5. Use the optional flush kit valve after each use of the system to
extend membrane life up to 6 months.
Storage
1. It is recommended that you store your Eliminator RO System in
a cool place when not being used.
2. Your Eliminator RO System must be protected from freezing or
temperatures above 110° F (43°C).
System Care
Choosing a Mounting Location
When considering a location for the installation of the System,
consider the following factors.
Light Sources
1. Most of the components of this system are plastic and are
subject to damage by ultra-violet light from the sun and other
sources such as metal halide lighting.
2. Algae is more likely to thrive inside the clear filter housings
when exposed to bright light.
3. Avoid installing this unit in bright light or direct sunlight.
Temperature Extremes
1. The unit must be kept out of areas that are subject to freezing
temperatures.
2. High temperatures greater than 110° F (43° C) must be
avoided. If the unit is used outside, avoid putting the system in
direct sunlight or connecting it to a garden hose that may be
exposed to sunlight.

Membrane Output
Calculation Example
What is the expected GPD from a 50 GPD MPRO-C System at 40 psi
pressure and 60°F water temperature?
PCF = 40 ÷ 60 = 0.666
TCF = 0.754 (from Table 1)
Expected GPD = 50 × 0.666 × 0.754 = 25.1 GPD ± 15%
Testing the Quality of the Membrane
The performance of a RO membrane is measured in terms of its
rejection characteristics.
Important: Test the quality of the membrane once every 6 months.
Note: This procedure will require a Conductivity Meter (TS-C61).
Procedure:
Membrane Testing
1. Measure tap water conductivity.* (Call it X.)
2. Run the system for 15-20 minutes.
3. Rinse test instrument cell 2-3 times with RO water.
4. Measure RO water conductivity.*(Call it Y.)
5. Subtract RO water conductivity*from tap water
conductivity.* (X - Y)
6. Divide this quantity by tap water conductivity.* (X - Y) ÷ X
7. Rejection = [(X - Y) ÷ X ] ×100
* Conductivity in the above procedure could be replaced by
hardness, alkalinity, nitrate, phosphate, silica etc. (measured in
ppm or mg/l).
1. Tap water hardness = 150 ppm (X)
2. RO water hardness = 7 ppm (Y)
3. X - Y = 143 ppm
4. (X - Y) ÷ X = 143 ÷ 150 = 0.953
5. Rejection = [ ( X - Y) ÷ X ] ×100 = 0.953 ×100 = 95.3
Membrane Hardness Rejection = 95.3 % Þ Membrane OK

Checking the
Concentrate to Purified Water Ratio
This procedure will be the most important factor in insuring that you
get the best possible results from your new system.
Failure to perform this procedure will void the pro-rated
Membrane Warranty.
In order to maximize the life of your SpectraPure ® RO Membrane,
you may need to adjust the ratio of the concentrate to purified
water. If not enough concentrate is allowed to flow past the
membrane during operation, the impurities can concentrate and
precipitate on the membrane surface, effectively clogging the
encapsulated RO Membrane. To keep this from happening, the
Concentrate to Purified Water Ratio should be checked and
adjusted at the highest temperature and pressure the system will be
operated at.
Procedure:
1. Open the cold water supply valve half-way and let the
system run for 1/2 hour.
2. Using two measuring cups, simultaneously place the
yellow concentrate tubing into one cup and the blue
purified water tubing into the other cup.
3. When the blue tubing cup has collected 2 oz. (or 100 ml.)
of water, simultaneously remove the tubing from both
measuring cups.
4. Note how many oz. (or ml.) of water the yellow tubing
cup has collected.
5. To calculate the Concentrate to Purified Water Ratio, divide
the number of oz. (or ml.) of concentrate by the number of
oz. (or ml.) of purified water.
Formula: Concentrate ÷ Purified = Concentrate to Purified Ratio
Examples: 8 oz (400 ml) ÷ 2 oz (100 ml) = 4:1 Ratio - Acceptable
10 oz (500 ml) ÷ 2 oz (100 ml) = 5:1 Ratio - Acceptable
6 oz (300 ml) ÷ 2 oz (100 ml) = 3:1 Ratio - Not Acceptable
If the ratio is less than 4:1 (as in the third example), the system must
be adjusted by reducing the length of the flow restrictor capillary
tubing as described on the next page. After modifying the flow
restrictor, repeat the above test and recalculate the Concentrate
to Purified Water Ratio.

SpectraPure ®Operating Instructions
1. Turn off system water supply.
2. Remove the yellow tubing from its gray push-fitting at the
encapsulated membrane as follows:
a.) With one hand, grasp the yellow tubing near the
membrane.
b.) With the thumbnail of your other hand, firmly depress
and hold the gray push-fitting down.
c.) While the gray push-fitting is depressed, pull the
yellow tubing straight out of the push-fitting. Once
the tubing is removed, release the gray push-fitting .
3. Carefully remove the flow restrictor assembly, now visible
as a translucent plastic insert in the end of the yellow
tubing. You may use an object such as a dull knife to help
pry the flow restrictor insert from the end of the tubing.
The entire length of flow restrictor (consisting of the insert
plug and thin capillary tubing attached) may then be
gently extracted.
Note: Take care not to crush or otherwise damage the
delicate capillary tubing.
4. To adjust the flow restrictor, the length of the capillary
tubing must be reduced. With a new single-edge razor
blade, carefully cut off approximately 1 inch (25.4 mm) of
capillary tubing from the flow restrictor assembly.
5. Re-insert the flow restrictor assembly into the yellow
tubing and firmly re-seat the restrictor plug into the end of
the yellow tubing by carefully pressing on the plug with
your thumbnail. Care should be taken not to crush or
otherwise damage the end of the capillary tubing
protruding from the end of the plug.

Membrane Output Calculation
Membranes produce the rated gallons per day (GPD) at 60 psi
(4.1 bars) operating pressure, 77°F (25°C) operating temperature
and 500 ppm total dissolved solids.
Membrane output gallons per day (GPD) depends on operating
pressure, water temperature and the ppm TDS in the feed water.
Expected GPD = Rated GPD × PCF × TCF
PCF is the pressure correction factor
TCF is the temperature correction factor
Calculation of Pressure Correction Factor (PCF):The output
(GPD) from the membrane is directly proportional to the applied
pressure.
Note: The membrane is rated to produce the rated GPD at 60 psi.
For any pressure other than 60 psi the output GPD is multipled by
the PCF.
PCF = Line Pressure (in psi) ÷ 60
Calculation of Temperature Correction Factor (TCF): The output
(GPD) also decreases with decrease in temperature. This is because
water viscosity increases with decrease in water temperature.

6. Re-insert the yellow tubing to its gray push-fitting in the
encapsulated RO membrane as follows:
a.) Moisten the o-ring seal inside the concentrate outlet
fitting by dripping a few drops of clean water into the
fitting.
b.) Grasp the yellow tubing near the flow restrictor end, and
insert the tubing into the gray push-fitting. Push the
tubing into the fitting until resistance is felt, approximately
1/2 inch (12.7 mm). The tubing in now resting on the o-
ring seal inside the fitting.
c.) Now firmly push the tubing approximately an additional
1/4 inch
(6.35 mm) further into the fitting to completely
seat the line into the fitting and o-ring seal.
7. Turn on the system water supply and check for leaks prior to
further use or testing. If a leak is observed, you may not have
pushed the yellow tubing into the gray push-fitting far
enough to seal the tubing against the o-ring. Turn off the
system water supply and reseat the tubing as described above.
8. Repeat the Concentrate to Purified Water Ratio test on page 5.
If the ratio is within the acceptable (4:1 or greater) limits, the
system is ready for use. If the ratio is still below the 4:1 limit,
repeat the flow restrictor adjustment process, removing
another 1 inch (25.4 mm) of capillary tubing from the flow
restrictor, reassembling the concentrate line, and re-testing the
Concentrate to Purified Water Ratio.
9. Repeat the above testing and adjustment procedure until the
Concentrate to Purified Water Ratio is 4:1 or greater.
