SYSTEM DESCRIPTION:
The SpectraPure® High Chloramine Removal system is a five -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 become fouled.
2. The second stage of filtration is a 1 micron Pentek ChlorPlus carbon block prefilter.
This filter removes organics and chlorine from the feed water that can damage the
membrane and any particulates that are not removed by the sediment filter. The Pentek
ChlorPlus filter provides greater chloramine performance capacities than granular
carbon filters.
3. The third stage of filtration is a second Pentek ChlorPlus filter. This ensures that the
maximum amount of chlorine and chloramines are removed before they can negatively
affect the performance of the RO Membrane.
4. The fourth 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.
5. The fifth stage moves water through a SilicaBuster®Mixed-Bed Multi-Layer Deionization
Cartridge. SilicaBuster®Deionization Cartridges are fabricated with semiconductor grade
resins for the 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 CO2(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 “IN Port” on page 4).
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. (See image below)
7. Attach the black tubing and elbow to the membrane housing cap.
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 green 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 “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. “Line 1” displays the Tap Water TDS. “Line 2” displays
the TDS of the RO Water. “Line 3” displays the TDS of the DI (product) Water.
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.
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 THREE-PROBE TDS METER (TRM-1 METER)
The digital TDS meter (three probe) will provide a reliable means of evaluating the
performance of the RO membrane and the Deionization Cartridge. The numbers
from the three 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 “Line 3”) displays “001”, it is time to replace
the DI cartridge. The system must be running when taking this reading.
Warning!!
The TRM -1 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.

TESTING THE 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 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 multiplied 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.
