GENERAL SYSTEM DESCRIPTION:
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 become
fouled. 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 most inorganic salts,
all microorganisms and almost all high molecular weight organics in the
water
are rejected by the membrane and sent down the drain.
These RODI systems have two stages of Deionization that polish the RO
water to less than one ppm purity.
The fourth and fifth stage filters are our
Mega MaxCap™ DI Cartridge and our Enduro DI™ High-Performance DI
Finishing Cartridge.
The Mega MaxCap™ DI Cartridge is used as a high-capacity “roughing”
cartridge and is followed by our Enduro DI™ high-performance finishing
cartridge. The Mega MaxCap™ DI cartridge has a much higher capacity,
but less purity than the Enduro DI™ cartridge. These DI cartridges work
in tandem to achieve a greatly extended lifespan when compared to
standard mixed-bed DI cartridges. Because the RO water reaches it first,
the Mega MaxCap™ will need to be replaced more often than the Enduro
DI™.
The Mega MaxCap™RODI system comes equipped with two Dual-Probe
Inline TDS meters for complete monitoring of water purity throughout
every stage of the purification process. The left-side TDS meter will monitor
the tap water TDS and the TDS of the RO water, allowing you to accurately
compute the rejection rate of the RO membrane. (See “Testing The Quality
Of The Membrane” on Page 15.) The right-side meter monitors the DI
cartridges to let you know when they need to be replaced. It will also
monitor the purity of your product water when set to the “Out” position.

A pressure -operated Automatic Shutoff (ASO) Valve and a Float Valve are
provided for convenient filling of a storage reservoir.
NOTE: SpectraPure does not recommend using the Float Valve for topoff
due to evaporation. The short duration of the fill cycle when using
a float valve will rapidly deplete the life of the DI cartridges due
to TDS creep. Instead, we recommend the use of high/low float
switches in the reservoir/sump to extend the fill cycle and minimize
the effects of TDS creep. (see SpectraPure part number LLC-SVC-
2FLT-2-10)
The Manual Flush Valve may 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. The Manual Flush
Valve is located in parallel with the flow restrictor (see page 9) 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. We recommend that the valve be turned ON for 30
seconds at the start of a fill cycle and at the end of a fill cycle. BE SURE to
turn the Flush Valve OFF before making product water.

OPTIONAL BOOSTER PUMP (BPHF-MF-115):
An optional Booster Pump is necessary for installations with less than 40
psi tap water pressure.
RO production is directly dependent upon water pressure, so the
production rate may be dramatically increased by adding a Booster
Pump Kit. When installed between the Carbon Block filter and the RO
Membrane, the pressure may be increased up to 80 psi.This would double
the production rate if the starting household water pressure is 40 psi.
Higher water pressure not only increases the rate of production, it also
results in higher rejection rates for the RO Membrane. Higher rejection
rates mean less contaminants reach the DI stages, thereby extending the
life of your DI Cartridges which are a more expensive way to filter water
when compared to Reverse Osmosis Membranes.
If you are interested in installing a Booster Pump Kit on your RO/DI system
or if you have any questions regarding a Booster Pump Kit, please contact
SpectraPure Support.
FLOW RESTRICTORS AND TEST STRIPS:
These systems are supplied with TWO Flow Restrictors (FR) - RED and
GREEN. (See images on Page 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” on Page 18.) 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.

SYSTEM INSTALLATION & INITIALIZATION:
1. Attach the black tap water tubing to the left side of the Sediment Filter Housing
(See page 8).
2. Attach the yellow drain line to the “Y”- connector at the rear of the system. This “Y”
-connector already has a yellow and red tube attached to it. (See page 9)
3. Attach the blue product line to the rear port of the
right-hand DI housing (Left-side housing when
viewed from rear. See image on right).
4. Attach the black tubing and elbow(s) to the
membrane housing cap(s). (See page 9)
5. Attach the garden hose adapter (connected to
the black tubing) to your cold water source.
6. Remove the two DI filter cartridges from the two right-hand filter housings.
Reconnect the two housings to their threaded caps. Hand tighten.
7. The 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. This will allow you to cut off the water supply to service the RO/
DI system without affecting the household water supply.
8. Place the yellow concentrate (waste) tubing and the blue purified (product)
water tubing temporarily into a drain. Do not restrict flow from these lines.
9. Let both tubings run water down the drain for 20 minutes.
10. Reinstall the two DI cartridges into the DI housings. Hand tighten.

• 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.
• 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.
• 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.

11. Insert the connectors at the end of the red, white and blue sensor wires into
the tops of the TDS meters. You can then use the Velcro on the back to mount
the meters wherever it is convenient. You may mount the meters on the
system itself (as shown) or on a wall for easier viewing.
12. Open the cold water supply valve. The pressure should not exceed 80 psi.
13. Upon startup, air may be trapped in the DI cartridges (housings 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 the Float Valve for automatic operation,
all air must be kept purged from the housings by slightly unscrewing the
housing(s) and letting the running water displace the air until the housings
are full of water.
14. Close the cold water supply valve.
15. Finish the installation by directing or connecting the yellow line to a
permanent drain.
16. Install the included Float Valve onto a collection reservoir. (See below.)
17. Attach the blue line to the Float Valve.
18. 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.)
19. It may take several days of normal operation for the membrane to reach its full
production rate.
FLOAT VALVE INSTALLATION:
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 Page 12) 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:
HOW THE FLOAT VALVE 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.
Notice: Using a mechanical float valve is not
recommended for direct sump topoff.

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. The
pressure will drop as the prefilters become clogged by dirt (turbidity) from
the tap water.
The two digital TDS meters will provide a reliable means of evaluating the
efficiency of the RO membrane, the state of the DI cartridges, and the purity
of the product water. The left-side meter shows Tap Water TDS when set
to “IN” and RO Water TDS when set to “OUT”. These measurements may
be used to calculate the efficiency (lifespan) of the RO membrane. (See
“Testing The Quality Of The Membrane” on Page 15.) The right-side meter
shows the TDS of the water coming from the Mega MaxCap™ cartridge
when set to “IN” and the TDS of the water coming from the Enduro DI™
cartridge when set to “OUT”. The reading from the “OUT” setting on the
right-hand meter is also the TDS of your final product water. (See “Mega
MaxCap DI Replacement” and “Enduro DI Replacement” on Page 21)

USING THE PRESSURE GAUGE:
The pressure gauge is used to monitor the condition of the Sediment
and Carbon Prefilters. With the Sediment and Carbon filters removed, the
gauge will indicate the “actual” tap water input pressure. When the prefilters
are “new”, the pressure shown on the gauge will be slightly less than the
actual tap water pressure and as the filters age, the pressure will drop due
to the sediment that will collect in the prefilters. When the pressure on the
gauge drops below 40 PSI or as the filters collect particulates and the
pressure drop is greater than 15% to 20% of the normal water pressure,
the prefilters are in need of replacement.
NOTE: When the pressure on the pressure gauge drops below the normal
readings; do not assume that the sediment filter is the only cause.
In some geographical areas where the input water contains a high
percentage of very small micron particulates, the carbon filter may
become clogged before the sediment filter. (The filters may look
“new” but still cause the water pressure to drop). Do not judge the
condition of the prefilters by their color, always use the pressure
gauge to determine the condition of the prefilters.
USING THE MANUAL FLUSH VALVE
The Manual Flush Valve can be an important factor in extending the life
of your RO membrane. It helps to flush the accumulated salts from the
membrane surface and also lowers the TDS in the membrane housing. We
recommend that you flush the system for 30 seconds upon startup and
again when shutting the system down.
When the handle is perpendicular to the tubing, the waste water is forced
to pass through the flow restrictor which builds backpressure in the
membrane housing and reverses the osmotic flow to produce pure water.
When the handle is parallel to the tubing, the water flows unimpeded
through the waste water line, resulting in a fast flow across the surface of
the membrane and down the drain line.

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). Use the TDS Meter located on the left
side of your system for this procedure.
General Procedure:
1. Slide the switch on the Left-Side TDS meter all the way to the left (IN).
Measure the tap water TDS. (Call it X)
2. Run the system for 15 -20 minutes.
3. Slide the switch on the Left-Side TDS meter to the right (OUT).
Measure RO product water TDS. (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
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 250 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 on previous page)
Expected GPD = 100 × 0.666 × 0.754 = 50.2 GPD ± 20%*
50.2 GPD would be the Actual Production Rate
*Membrane manufacturers state their flow ratings with a ± 20% variance.
TIPS FOR LONG MEMBRANE LIFE:
1. Replace the sediment filter at least once every 6 months. This will
prevent membrane fouling due to silt or sediment depositing on the
membrane.
2. Replace the 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

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.

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
lifespan 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 to be replaced is to monitor
the Pressure Gauge. When you have a drop in pressure of15-20% 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 wrench, remove the first housing on
the left. Unscrew it clockwise as viewed from the top.
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 to be replaced 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 waste water 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.
**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 can 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 clockwise as viewed from the top.
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.
