GENERAL SYSTEM DESCRIPTION:

This SpectraPure® RODI System gives you a continuous supply of sparkling
clear water. The reliability with the SpectraPure® Water Treatment System is
greatly improved over other systems. Costly maintenance can be avoided,
providing high quality water at your fingertips.

The incoming feed water from a cold water source is directed through
BLACK tubing with an inline ball valve and is first passed through a
sediment prefilter. This filter is used to remove excessive turbidity, sand,
dust, silt, etc., that would otherwise cause the carbon filter to plug up.
The next stage of filtration is the carbon block prefilter. This filter is used to
remove organics and chlorine from the feed water that can damage the
membrane. The next stage of the system is the RO membrane.

Household water pressure is used to force tap water through the
semipermeable RO membrane. The membrane only allows the purest of
water molecules to pass through it while over 98% of

all microorganisms and almost all high molecular weight organics in the
water

are rejected by the membrane and sent down the drain.

most inorganic salts,

This RODI system has a one stage Deionization cartridge that polishes the
RO water to less-than-one ppm purity. This is

Life Super DI cartridge.

The CSPDI RODI system comes equipped with a three-probe Inline TDS
meter. The TDS meter can monitor three steps in the purification process.
Line 1 of the meter shows the tap water TDS. Line 2 of the meter shows
the TDS of the RO water. Line 3 of the meter shows the TDS of the final
product water (out of the SilcaBuster DI).

A pressure-operated Shutoff Valve and a Float Valve are provided for
convenient filling of a storage reservoir.

A Manual Flush Valve (-MF) can be used to periodically rinse the
accumulated impurities and concentrated waste water from the surface of
the RO membrane to help increase the life of the membrane.

An Automatic Flush System (-AF) can be used to periodically rinse the
accumulated impurities and concentrated waste water from the surface of
the RO membrane to help increase the life of the membrane.

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 6 or 7).

5. Attach the yellow drain line to the “Y”- connector at the rear of the system. This
“Y”- connector already has a yellow and green tube attached to it.

6. Attach the blue product line to the front port of the right-hand DI housing.

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

8. Unscrew the right DI housing and remove the DI cartridge. Reconnect the
empty housing to the threaded cap. Hand tighten.

9. 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.

10. A provided 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.

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

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

14. 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.)

15. Run both the blue and yellow tubings down the drain for an hour, then
reinstall the DI cartridge. Hand tighten.

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 section. However, when you later install the Float Valve for
automatic operation, all air must be kept purged from the housing by slightly
unscrewing the housing and letting the running water displace the air until
the housing is full of water. Hand tighten housing once air has been purged.

17. Set the meter to “Line 3” and run the system until the meter reads zero. The
water is now ready to use. You can set the meter to monitor either of the
3 probes at any time.

18. Close the cold water supply valve.

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

20. Install the included Float Valve onto a collection reservoir. See below.

21. Attach the blue line to the Float Valve.

22. (For -AF Systems) Connect the supplied power supply to the black 2.1 mm
Mini Plug. (See page 9)

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

reach its full production rate.

INSTALL THE FLOAT VALVE:

1. Drill a 1/2" hole near the top of your reservoir:

NOTE: If you are installing the Float Valve onto an acrylic tank we

recommend using a new Fostner Bit to reduce the chance of
cracking the acrylic.

2. (Refer to Diagram on next page) Remove the Compression Nut from
the float body.

3. Insert the 1/4" Blue Tubing into the 1/2" Compression Nut with the
threads towards the end of the tube.

4. Unscrew and remove the remaining nut from the float body.

5. Insert the float body and washer into the 1/2" hole and tighten the
nut, which securely tightens the float to the tank wall.

6. Push the Compression Nut towards the end of the tubing and screw
the Compression Nut back onto the float body.

7. To tighten, use one 1/2" wrench on the flats of the plastic threads and
another 1/2" wrench on the Compression Nut.

FLOAT VALVE ILLUSTRATION:

FLOW RESTRICTORS AND TEST STRIPS:

These systems are supplied with TWO Flow Restrictors (FR) - RED and
GREEN. See Pages 8 and 9. The RED FR (pre-installed) produces a preset
waste-to-product ratio of 3:1 and the optional GREEN FR has a 2:1 ratio.

Two Test Strips are provided to determine the Total Hardness (this is NOT
TDS) of your tap water. To test: Dip the colored end into a small tap water
sample for 3 seconds. Remove and do not shake. Wait for 20 seconds and
then match with the closest color block on the back of the package. Color
is stable for 1 minute.

If the Total Hardness is 180 or greater, you should keep the RED FR installed.
If the Total Hardness is less than 180, you may replace the RED FR with
the GREEN FR (see “Working with Push Fittings”). Be sure to note the
orientation of the small “plug” in the end of the removed FR and install the
new FR with the same orientation.

The RED FR has a waste-to-product ratio of 3:1, which will increase the
amount of water used, but also increase the lifetime of the RO membrane.
In hard water conditions, you may use the GREEN FR to save water, but
the RO membrane will not last as long, as it will plug up with hardness
much more quickly.

HOW IT WORKS:

The increasing water level raises the Float Valve in the reservoir and stops
the flow of water. Pressure builds up in the product line and ASO Valve until
the ASO Valve shuts off the flow of waste water to drain. This “OFF”
condition will be maintained until the reservoir needs more water and the
Float Valve drops, allowing both product and waste water to flow again.

NOTE: This configuration maintains house pressure in the prefilters,

membrane, and pressure gauge when in the “OFF” condition.
Also, this system WILL NOT WORK with any kind of “bladder tank”
attached to the product line.

An optional float kit can be used for filling an additional sump or reservoir.
Our Float Kit (SPFK) includes a Float Valve and 1/4" Union Tee.

THE MANUAL FLUSH VALVE (-MF Versions):

The Manual Flush Valve is located in parallel with the flow restrictor (see
page 8) and, when opened, provides a high flow bypass of waste water
used to purge concentrated brine from the membrane housing and rapidly
flush any particulates from the membrane surface. This is especially useful
in hard water conditions. The valve can be turned ON for 30 seconds at
the start of a fill cycle and/or at the end of a fill cycle. BE SURE to turn the
Flush Valve OFF before making product water.

An optional Booster Pump can be added for installations with less than 40
psi tap water pressure. Be sure to use the BPHF-MF-115 Booster Pump Kit.

THE AUTOMATIC FLUSH VALVE (-AF Versions):

The Automatic Flush Valve is located in parallel with the flow restrictor
and, when electrically activated, provides a high flow bypass of waste
water used to purge concentrated brine from the membrane housing and
rapidly flush any particulates from the membrane surface. This is especially
useful in hard water conditions. A Pressure Switch and Flush Control
Module (AFC) will activate the Flush Valve at the start of a fill cycle, at the
end of a fill cycle, and for a short time every hour during the fill cycle. This
module is powered by a 24VDC power supply. An optional Booster Pump
can be added for installations with less than 40 psi tap water pressure.
Only use a power supply rated at 24VDC, 2.5A that comes with the
Booster Pump Kit (BPHF-AF-115). Connect the Pump to the black/black
wires on the AFC Module.

Notice: Drinking water add-on kits and bladder tanks are

not compatible with Automatic Flush (AF) systems.

BOOSTER PUMP INSTALLATION (Both Versions):

If needed, install the Booster Pump on the black tap water feed line. Be
sure the arrow on the pump head is in the direction of the flow. Replace
the small black power supply (-AF Systems) with the larger black power
supply provided with the Booster Pump Kit. Connect the remaining free
wires and connector on the AFC module to the pump. Systems with 25
and 40 GPD RO membranes should first consider upgrading to the 90
GPD membrane before aquiring the Booster Pump.

SEDIMENT PREFILTER REPLACEMENT:

A Sediment Filter will usually last approx. 4-6 months, depending on the
quality of the tap water and quantity of water being produced. (The life
span of the filter is determined by the turbidity, iron content, organics,
and total particulate volume in your water source). The best way to
determine when your Sediment Prefilter needs replacement is to monitor
the Pressure Gauge. When you have a drop in pressure of 15-20% below
your normal gauge pressure, replace the filter. To verify this, run water
through the system without the filter in its housing. If the pressure returns
to your normal house pressure without the filter, you will know the filter
you just took out was plugged up and causing the pressure drop.

**NOTE: A drop in the system’s production is, in most cases, an indication
that the sediment filter has become saturated with contaminants and will
need to be replaced. If you remove the sediment and the pressure does
not return to normal, the carbon filter may be plugged. 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: Sediment prefilter (SF-MT-0.5-10),

Filter Wrench (WR-UNIV)

Procedure:

1. Turn off water supply to the system.

2. Using the provided filter housing
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. Insert the new prefilter into 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 BLOCK FILTER REPLACEMENT:

A Carbon Filter will usually lasts 4- 6 months ,depending on the chlorine
(or chloramine) content of your tap water and quantity of water being
produced. The best way to determine when your Carbon Block Prefilter
needs replacement is to use a chlorine test kit.

Any chlorine level above 0.1 ppm will cause damage to the membrane
and indicates that the carbon block filter must be changed. To test for
chlorine breakthrough, collect a 10 ml sample of the concentrate from
the yellow tubing and test the chlorine concentration using test kit TK-CL­10-KIT. If the chlorine concentration is above 0.1ppm, replace the carbon
prefilter.

**NOTE: A drop in the system’s production is, in most cases, an indication
that the sediment filter has become saturated with contaminants, but a
carbon filter may also decrease production if it’s covered with extremely
fine sediment. If the carbon becomes plugged with sediment, it will no
longer be able to remove chlorine.

Carbon Block Filter Replacement

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

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

Procedure:

1. Turn off water supply to the system.

2. Using the provided filter housing wrench, remove the second housing

from 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. Insert the new carbon block filter into 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. Turn on system water supply and check for leaks.

2. Remove the black tubing from the membrane feed push fitting by
depressing the collar on the fitting with your thumb and pulling the
tubing from the push fitting. You should not have to remove the blue
and yellow tubes.

3. Lift the membrane housing from the retention clips and unscrew the
membrane housing cap. This may require two people.

4. Use a pair of pliers to grasp the membrane stem and pull the membrane
from the housing.

5. Remove the black housing O-ring. Wash the empty housing with soapy
water. Rinse thoroughly with hot, clean water.

6. Insert the new membrane into the housing, with the double O-ring
end first. The O-rings and tube must fit into the recess at the bottom
of the membrane housing. When the membrane is aligned with the
recess, firmly push the membrane into the recess until it bottoms out.

7. Place the black housing O- ring on the housing rim and carefully screw
the lid back on to the base. Hand-tighten.

8. Reconnect the black tubing to the membrane feed push fitting.

9. If you have a dual-membrane system (-180), perform steps 2 thru 8 on
the second membrane.

10. Open the Flush Valve and allow the system to flush for several minutes
to remove any loose particles.

11. Close the Flush Valve and turn on the water supply to the system.

12. Check for leaks.

RO MEMBRANE DIAGNOSTICS:

In order to accurately determine the condition and performance of the
RO Membrane, a conductivity tester capable of reading the tap water
conductivity (or TDS) and the product water conductivity (or TDS) would
typically be required. The CSPDI system comes equipped with such a
device.

You may also use an alkalinity test kit (on softened water sources) or a
hardness test kit (on non-softened water sources).

Note: All water sources are different and are subject to changes in
conductivity from season to season which could affect the TDS
reading depending on the time of the year. For this reason, we
recommend the use of a conductivity (TDS) tester in order to determine
the most accurate measurement for determining the condition of the
RO membrane.

TESTING THE QUALITY OF THE MEMBRANE:

The performance of a RO membrane is measured by its ability to reject
salts or TDS (Total Dissolved Solids). This test may be done using the TRM-1
meter that comes factory-installed on the CSPDI system.

General Procedure:

1. Before doing this test, make sure that the system has been running for

at least 10 minutes.

2. Set the switch on the meter to “Line 1”. This will give you the tap water

TDS. Call it X.

3. Set the switch on the meter to “Line 2”. This will give you the TDS of

the RO water. Call it Y.

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

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

6. Rejection = [(X - Y) ÷ X ] ×100

TDS in the above procedure is measured in ppm or mg/l.

Important: Test the quality of the membrane once every 6 months.

Rejection of the RO Membrane Calculation Example

1. Tap water TDS = 150 ppm (X)

2. RO water TDS = 15 ppm (Y)

3. X - Y = 135 ppm

4. (X - Y) ÷ X = 135 ÷ 150 = 0.90

5. Rejection = [ ( X - Y) ÷ X ] ×100 = 0.90 ×100 = 90%

NOTE: Rejection rates less than 95% may indicate that the membrane should be

replaced.

MEMBRANE PRODUCTION CALCULATION:

Membranes produce the rated gallons per day (GPD) at 60 psi (4.1 bars)
operating pressure, 77°F (25°C) operating temperature and with no more
than 500 ppm total dissolved solids.

Membrane output gallons per day (GPD) depends on operating pressure,
water temperature and the 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 multiplied by the PCF.

PCF = Line Pressure (in psi) ÷ 60

Calculation of Temperature Correction Factor (TCF): The output (GPD)
decreases with a decrease in temperature. This is due to water viscosity
increasing with a decrease in water temperature.

Membrane Output Calculation Example

What is the expected GPD from a 100 GPD System at 40 psi pressure and
60°F water temperature?

PCF = 40 ÷ 60 = 0.666
TCF = 0.754 (from Table above)

Expected GPD = 100 × 0.666 × 0.754 = 50.2 GPD ± 15%

50.2 GPD would be the Actual Production Rate

TIPS FOR LONG MEMBRANE LIFE:

1. Replacement of sediment filter at least once every 6 months.This will

prevent mem brane fouling due to silt or sediment depositing on the
membrane.

2. Replacement of 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. Membrane should not be operated at lower than the minimum 2:1

concentrate to purified water ratio.

4. Operating reverse osmosis systems on softened feed water greatly

reduces the chances of membrane fouling.
