SYSTEM DESCRIPTION:

The SpectraPure® CSPDI™ system is a four-stage reverse osmosis deionization system.

1. First, the incoming feed water is passed through a 0.5 micron MicroTec™ sediment

prefilter. This filter is required to remove excess turbidity (particulate matter) that may
cause the membrane to plug.

2. The second stage of filtration is a 0.5 micron carbon block prefilter. This filter

removes organics and chlorine from the feed water that can damage the membrane.
(9,000 gal of water with 1 ppm Chlorine removal)

3. The third filtration stage of the system is a high rejection, thin film composite (TFC)

reverse osmosis membrane. It removes, on average, 98% of most inorganic salts, all
microorganisms and almost all high molecular weight organics in the water.

4. The fourth stage moves water through a SilicaBuster Mixed-Bed Multi -Layer Deionization

Cartridge. Mixed-Bed Multi-Layer Deionization Cartridges are fabricated with semiconductor
grade resins for highest possible purity water. They are capable of producing 18 megohm-cm
resistivity water. They are the first DI cartridges designed to reduce silica, nitrates and
phosphate levels in the low ppb range. These newly formulated cartridges far exceed the
performance of previous cartridges, offering enhanced contaminant removal, longer life and
higher purity.

Caution: The deionization cartridge life is greatly reduced when operated

on low pH waters or water with high CO

2

(carbon dioxide) levels.

The exact cartridge life will vary greatly with pH, carbon dioxide levels, TDS,
etc., in your RO water or the feed water supplying the RO system. Aeration
or degasification of RO product water is recommended for such waters for
removal of carbon dioxide.

WORKING WITH PUSH FITTINGS:

Push fittings are very reliable and convenient tubing connectors.

To remove the tubing from its push fitting:

1. Firmly depress and hold the push fitting collar down with your thumbnail.

2. While the push fitting collar is depressed, pull the tubing straight out

of the push fitting. Once the tubing is removed, release the collar.

To reinsert the tubing into its push fitting:

1. Moisten the O-ring seal inside the push fitting by dripping a few drops

of clean water into the fitting.

2. Grasp the tubing near the end, and insert the tubing into the push

fitting.

3. 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.

4. 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
past the O -ring seal.

5. 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
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.

SYSTEM INSTALLATION & INITIALIZATION:

1. Most of the components of this system are plastic and are subject to damage by
ultraviolet light from the sun and other sources such as metal halide lighting.

2. Avoid installing this unit in an area where it may be subjected to bright light
or direct sunlight, as algae is more likely to thrive inside the clear filter housings
when exposed to bright light. The unit must be kept out of areas that are
subject to freezing temperatures.

3. High temperatures greater than 113° F (45° 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.

4. Attach the black tap water tubing to the left side of the Sediment Filter Housing
(See page 5).

5. Attach the yellow drain line to the union connector at the rear of the system. This
connector already has a red tube attached to it.

6. Attach the blue product line to the front port (after the “tee”) of the right-hand
DI housing.

7. Attach the black tubing and elbow(s) to the membrane housing cap(s).

8. Attach the garden hose adapter (connected to the black tubing) to your
cold water source. Never run hot water (greater than 113° F/45° C) through
the system.

9. Remove the DI filter cartridge from the right-hand filter housing. Reconnect
the housing to its threaded cap. Hand tighten.

10. An optional ball valve can be located at a convenient place on the black tap
water line. Cut the black tubing in two and reconnect the two cut ends with
the ball valve, if desired.

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

12. Let both tubings run water down the drain for one hour.

13. Reinstall the DI cartridge into the DI housing. Hand tighten.

14. There is a group of red, white, and blue sensor wires. At the end of the wires,
you will find a white connector. Just insert the connector into the receptacle
on the top of the TDS monitor. You can then use the Velcro on the back to
mount the meter wherever it’s convenient. For example, even on a wall for
easier viewing.

15. Open the cold water supply valve. The pressure should not exceed 80 psi.

16. Upon startup, air may be trapped in the DI cartridge (housing may not appear
full), this is a normal condition and it will not affect the operation of the DI
system. However, if you later install an ASO Valve/Check Valve/Float Valve for
automatic operation, all air must be kept purged from the housings by slightly
unscrewing the housing and letting the running water displace the air until the
housing is full of water. When full, hand tighten the housing.

17. Set the meter to “OUT” and run the system until that meter reads zero. The
water is now ready to use. You can set the meter to read either probe at
any time. The “IN” position displays the TDS coming out of the RO membrane.

18. Close the cold water supply valve.

19. Finish the installation by directing or connecting the yellow line to a
permanent drain.

20. Check the system to ensure that all fittings are tight and leak-free before leaving
the system unattended. (If anything is leaking, contact SpectraPure for assistance.)

NOTE: It may take several days of normal operation for the membrane to

reach its full production rate.

SYSTEM INSTALLATION & INITIALIZATION: (cont.)

CHECK:

» Ensure that all fittings are tight and leak-free before leaving the

system unattended.

» The red concentrate (waste) line includes a smaller capillary tube

(flow restrictor) that is located “inside” of the tubing. Do not
remove or discard this restrictor - the system will not produce
permeate (product )water without the flow restrictor.

METERING AND DIAGNOSTICS:

This SpectraPure purification system has been fully equipped with sufficient
instrumentation to make monitoring and troubleshooting an easy process. The
provided pressure gauge is used to determine the tap water pressure and to
evaluate the condition of the sediment and carbon prefilters.

USING THE PRESSURE GAUGE

The pressure gauge is used to monitor the condition of the Sediment and Carbon
Prefilters (not the RO Membrane). When the filters are new, the gauge will
indicate the actual available house water pressure. As the filters collect particulates,
the pressure will begin to drop. A 15-20% (or more) drop in pressure would
indicate that the prefilters are in need of replacement.

USING THE DUAL PROBE TDS METER (DM1 METER)

The digital TDS meter (dual probe) will provide a reliable means of evaluating the
performance of the RO membrane and the Deionization Cartridge. The numbers
from the two probe readings can be used to calculate the percentage of rejection
of the RO membrane and the exhaustion point of the DI Cartridge.

Procedure for testing the RO Membrane:

1. Follow the instructions on page 11.

Procedure for testing the Deionization Cartridge:

1. When the reading on the probe (set to “OUT”) displays “001”, it is time to replace
the DI cartridge.

Warning!!:

The DM1 TDS Meter does not detect the presence of CO2, silica, organic
contaminants or microorganisms, nor should it be used as a medical or scientific
instrument. It should be used as an indicator or guide only, and does not imply
water safe for human consumption. No application other than monitoring the
electrical conductivity of water is expressed or implied.

RO MEMBRANE REJECTION DIAGNOSTIC:

In order to accurately determine the condition of the RO Membrane,
reconfiguring the DM1 TDS Meter, provided with this unit, is required.

Procedure:

1. Disconnect the BLACK line from the first stage housing (Sediment Filter)

2. Next, disconnect the “IN” Probe Tee of the DM1 meter and connect it to
the end of the black line. (This step will allow you to determine the TDS
of your tap water)

See page 7 for removal of tubing from push fittings.

3. Slowly turn the tap water on. Be careful where you point the open
fitting of the tee. Once you get a good flow coming out of the end of
the tee you can test the water:

- TAP WATER TDS READING (X):_______________

4. Once you obtain the tap water TDS reading, reconnect the “IN” Probe
Tee back to its original location.

5. Reconnect the BLACK line to the first stage housing (sediment filter)
and run water through the system for 15 min.

6. Note the reading on the meter with the setting still in the “IN” position:

- RO WATER TDS READING (Y):_______________

7. Subtract RO water TDS from tap water TDS. (X - Y)

8. Divide this quantity by tap water TDS. (X - Y) ÷ X

9. Rejection = [(X - Y) ÷ X ] ×100

Rejection of the RO Membrane Calculation Example

1. Tap water TDS = 150 ppm (X)

2. RO water TDS = 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 TDS Rejection = 95.3 %: Rejection rates less than 95% indicate
that the membrane should be replaced.

MEMBRANE OUTPUT CALCULATION:

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 250 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.

Temperature Correction Factor Table (TCF)

Membrane Output Calculation Example

What is the expected GPD from a 90 GPD System at 40 psi pressure and 60°F
water temperature?

PCF = 40 ÷ 60 = 0.666
TCF = 0.754 (from Table 1)
Expected GPD = 90 × 0.666 × 0.754 = 45.2 GPD ± 15%

45.2 GPD would be the Actual Production Rate

SEDIMENT PREFILTER REPLACEMENT:

For maximum contaminant removal and long membrane life, the sediment and carbon
prefilters must be changed when a 15-20% drop in pressure is observed OR at least 6 month
intervals. If your water contains a great deal of sediment or chlorine, the prefilters may require
more frequent changes to maintain adequate production rate and extended membrane life.

Sediment Prefilter Replacement

Materials Required: 0.5 micron MicroTec™ Sediment Filter (SF-MT-0.5-10), Filter Wrench

Procedure:

1. Turn off water supply to the system.

2. Using the provided filter wrench, remove the first housing on the left. Unscrew it by
rotating it to the left.

3. Remove the old filter and discard.

4. Thoroughly wash the housing with a mixture of hot soapy water and a few teaspoons
of household bleach. Rinse well with clean hot water.

5. Install the new prefilter onto the round port in the head of the housing. Screw the
housing back onto the assembly, and hand tighten only.

NOTE: Do not use filter wrench to tighten housings. Over-tightening will damage

housings and void your warranty.

6. Proceed with carbon block filter replacement.

CARBON PREFILTER REPLACEMENT:

For maximum contaminant removal and long membrane life, the sediment and carbon
prefilters must be changed when a 15-20% drop in pressure is observed OR at least 6-month
intervals. When chlorine breakthrough greater than 0.1 ppm occurs in the yellow concentrate
line, test for chlorine breakthrough by collecting a 10 ml sample of the concentrate from the
yellow tubing and test the chlorine concentration using test kit TK-CL-10-KIT. If the chlorine
concentration is above 0.1ppm, replace the carbon prefilter.

Carbon Block Filter Replacement

Materials Required: 0.5 micron Carbon Block Filter (CF-0.5 -10), Filter Wrench,

Chlorine Test Kit (TK-CL-10-KIT)

run water through system for at least 2 gallons. (This step will flush out
membrane preservatives.)

3. Reinsert flow restrictor and check for leaks. Allow at least 2 gallons of
water to run through the system before using water.

TIPS FOR LONG MEMBRANE LIFE:

1. Replace the 0.5 micron sediment filter once every 6 months. This will
prevent mem brane fouling due to silt or sediment depositing on the
membrane.

2. Replace the 0.5 micron carbon block filter at least once every 6
months or when chlorine breakthrough occurs. This will ensure good
membrane life and protect the membrane from chlorine damage.

3. Operating reverse osmosis systems on softened feed water greatly
reduces the chances of membrane fouling.

4. Use the optional flush valve kit after each use of the system to extend
membrane life.

STORAGE:

1. It is recommended that you store your RO System i n a co ol p la ce
when not being used.

2. If your system is exposed to sunlight you will grow algae in the h ousing
and it may damage your system.

3. Your RO System must be protected from freezing or t em p e ra t u r e s
above 113° F (45°C).

4. Replacement membranes should be kept in the sealed non-permeable
shipping bag and in a refrigerator until use. The membrane may be
kept there for up to 1 year. (DO NOT FREEZE)
