SYSTEM DESCRIPTION :

The incoming feed water from a cold supply pipe valve is directed through 3/8” BLACK
tubing and is first passed through a 1 micron Micro-Tec™ sediment pre-filter. This filter is
used to remove excessive turbidity, sand, dust, silt etc.that may cause the carbon filter to
plug up. The next two stages of filtration is a 5 and 1 micron carbon block pre-filter. These
filters are used to remove organics and chlorine from the feed water that can damage the
membrane. The final stage of the system is the R.O. membrane. A high rejection Thin Film
Composite (TFC) membrane is used in this system. This removes as much as 98% of most
inorganic salts, all micro-organisms and almost all high molecular weight organics in the
water.

SYSTEM INITIALIZATION

If you are setting up your system for the first time or replacing a
membrane, p
Ratio” section on page 6-8 .

SYSTEM HOOK-UP:

1. Attach the garden hose adapter (black tubing) to your cold water
source. Never run hot water (greater than 100° F (38° C)) through
the system.

2. Place the yellow concentrate (waste) tubing and the blue purified
(product) water tubing into a drain. Do not restrict flow from these
lines.

3. Open the cold water supply valve. You may use pressure up to 80 psi
(5.5 bar).

lease see the “

Checking the Concentrate to Purified Water

Check the system to ensure that all fittings are tight and
leak- free before leaving the system unattended. Monitor for
at least 72 hrs.

Note: It is recommended that at least 2 gallons (7.57 liters) of purified
water be discarded now before collecting purified water for use. If the
unit is not used for several days, run the system for at least 10 minutes
before collecting any water. This will flush out any stale water in the
system.

4. Finish the installation by connecting the yellow line to a drain. The
blue line can be placed into a Rubber Maid™ trash can or set up
automatically using a Liquid Level Controllers. (Liquid Level
Controllers and Automatic shut off accessories sold separately.)

CHECKING THE CONCENTRATE TO PURIFIED WATER RATIO:

This procedure will assure you of maximum life and reliability of your SpectraPure System.
Failure to perform this procedure can permanently damage the membrane and 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 will precipitate out on the membrane
surface, clogging the RO Membrane. To keep this from happening, the Concentrate to Puri­fied Water Ratio must be checked and adjusted in order to compensate for pressure and
temperature variations that exist in all water supplies. The flow rate of the concentrate must
be a minimum of 3X the product flow rate. 3X to 5X is an acceptable concentrate flow rate.

Procedure:

1. Locate the Yellow waste line. Direct the waste line into a sink drain.

2. Locate the Blue product line . Direct the product line into a sink drain.

3. Turn on the Feed Supply Valve and let the system run for 20 min.

4. Collect product water from the blue line into a measuring cup for one
minute. Measure the collected amount in milli-liters. (30 ml = 1 oz) Do
the same with the waste water.

WASTE IN MILLILITERS______________ML

DIVIDED BY

PRODUCT IN MILLILITERS______________ML

The resultant is the Concentrate to Product Ratio

(Although not needed in this procedure, the daily product flow rate in Gallons per

Day (GPD) can be calculated to be equal to the product flow rate times 0.38 ).

5. If ratio is less than 3:1= Remove Flow Restrictor as shown on page 8-9 and
cut 1” off.

6. Re-measure your ratio and repeat proceedure untill you acheive a 3/1 ratio.

7. If ratio is greater than 5:1, flow restrictor requires replacement

FLOW RESTRICTOR REMOVAL, ADJUSTMENT, AND REPLACEMENT:

1. Locate the yellow concentrate tubing (Page 8) Remove the tubing from its push-fitting at
the membrane as follows:
a.) Firmly depress and hold the push-fitting collar down with your thumbnail.
b.) While the push-fitting collar is depressed, pull the tubing straight out of the
push-fitting. Once the tubing is removed, release the collar.

2. Carefully remove the flow restrictor assembly, now visible as a plastic insert in the end of the
yellow tubing (Fig. B). 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 flow restrictor (consisting of the insert
coller and thin capillary tubing) may then be gently extracted.

Note: Sometimes, the Flow Restrictor might get stuck in the membrane fitting. To remove, use
needle nose plyers and rock the collar back and forth, while pulling. Take care not to crush,

stretch or otherwise damage the delicate capillary tubing.

3. Using a new single-edge razor blade, carefully measure and then cut the flow restrictor.

4. Re-insert the flow restrictor assembly into the yellow tubing and firmly re-seat the insert into
the end of the yellow tubing by carefully pressing on the insert with your thumbnail. Care
should be taken not to crush or other-wise damage the end of the capillary tubing
protruding from the end of the insert.

5. Re-insert the yellow tubing into its push-fitting in the 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
push-fitting. Push the tubing into the fitting until resistance is felt, approximately 1/2
inch (12.7 mm). The tubing is now resting on the O-ring seal inside the fitting.
c.) 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.

6. 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 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.

TESTING QUALITY OF THE MEMBRANE

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.

double
O-ring end of
membrane
product

tube

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.

Membrane Output Calculation Example

What is the expected GPD from a 75 GPD System at 40 psi pressure and 60°F
water temperature?

PCF = 40 ÷ 60 = 0.666
TCF = 0.754 (from Table 1)
Expected GPD = 75 × 0.666 × 0.754 = 37.7 GPD ± 15%

Performance Test

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:

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).

Rejection of the RO Membrane Calculation Example

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 % : Membrane OK
