Choosing a Mounting Location
When considering a location for the installation of the
RO System, consider the following factors:
Light Sources
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. Algae is more likely to thrive inside the clear filter housings
when exposed to bright light.
3. Avoid installing this unit in bright light or direct sunlight.
Temperature Extremes
1. The unit must be kept out of areas that are subject to freezing
temperatures.
2. High temperatures greater than 100° F (38° 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.

System Description
The MaxPure™ MPDI System is a four stage reverse osmosis/
de-ionization system.
1. First, the incoming feed water is passed through a 1 micron micro-tec
sediment pre-filter. 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 10 micron carbon block pre-filter.
This filter removes organics and chlorine from the feed water that
can damage the membrane.
3. The third filtration stage of the system is a high rejection thin film
composite (TFC) reverse osmosis membrane. It removes over 98% of
most inorganic salts, all micro-organisms and almost all high molecu
lar weight organics in the water.
4. The fourth stage moves water through a color change strong based
anion cartridge. The anion exchange resin removes all negative ions
and replaces them with hydroxyl ions.
This super-capacity RO/DI system consists of newly developed color-indicating DI resin cartridges with twice as much phosphates/silica removal
resin as in previous designs.
It is recommended that you keep replacement cartridges on hand,
ready to install as soon as the cartridge becomes exhausted.
Operating the Push-Fittings
The push-fittings used on SpectraPure products can be easily serviced.
To remove the tubing from its push-fitting:
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.

Tips for Long Membrane Life
1. Replacement of 1 micron sediment filter once every 6
months. This will prevent mem brane fouling due to silt or
sediment depositing on the membrane.
2. Replacement of 10 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. Membrane should not be operated at lower than the
recommended concentrate to purified water ratios, as
described on page 6.
4. Operating reverse osmosis systems on softened feed
water greatly reduces the chances of membrane fouling.
5. Use the optional flush kit valve after each use of
the system to extend membrane life up to 6 months.
Storage
1. It is recommended that you store your RO System
in a cool place when not being used.
2. Your RO System must be protected from freezing or
temperatures above 100° F (38°C).

1. Remove the DI cartridge from the right-most housing and
re-install the empty housing.
2. Attach the garden hose adapter to your cold water source.
Never run hot water (greater than 100° F (38° C)) through
the system.
3. Place the yellow concentrate tubing and the blue purified
water tubing into the drain. Do not restrict flow from these
lines.
4. Slowly open the cold water supply valve and allow
the first two housings to fill. You may use pressure up to
80 psi (5.5 bar).
5. Check the system to ensure that all fittings are tight and
leak-free before leaving the system unattended.
6. Allow the system to produce at least 2 gallons (7.57 liters)
of purified water and discard.
7. Check the Concentrate to Purified Water Ratio by follow
ing the set-up instructions on the next page.
8. Close the cold water supply valve. Locate and re-install the
DI cartridge.
9. Slowly open the cold water supply valve and discard the
first gallon of product water.
Note: Air trapped in the DI cartridges is a normal condition
and will not affect the operation of the DI cartridges. Mounting
the blue product water tubing so that at least a short length
of tubing is higher than the filter unit can often alleviate this
condition.

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%
37.7 GPD would be the Actual Production Rate
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)).
Important: Test the quality of the membrane once every 6 months.
Note: This procedure will require a Conductivity Meter (TS-C61) or (TS-T71).
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 directly from the blue product
water line. (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 % : Rejection rates less than 95% may
indicate that the membrane should be replaced.

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.
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.

System Set-Up
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
membranes 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 4X the product flow rate. 4X to 6X is an
acceptable concentrate flow rate.
Procedure:
1. Open the cold water supply valve and let the system run for
15 minutes.
2. Collect product water from the blue tubing into a measuring
cup for two minutes. Measure the collected amount in milli liters and divide by 2. The resultant is the product flow
rate in Milliliters per Minute.
(Although not needed in this proceedure, the daily product
flow rate in Gallons per Day (GPD) can be calculated to be
equal to the product flow rate times 0.38 ).
3. Use the procedure and tables on the following pages to
determine the optimum length of the flow restrictor
capillary
tubing. After adjusting the flow restrictor, repeat the above
procedure and recheck the Concentrate to Purified Water
Ratio.

System Set-Up
Flow Restrictor Removal, Adjustment, and Replacement
1. Locate the yellow concentrate tubing (Fig. B). 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. C). 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 plug and thin capillary
tubing) may then be gently extracted.
Note: Take care not to crush or otherwise damage the delicate capillary tubing.
3. Refer to the Flow Restrictor Tables (Fig. D). Find the table that represents the
Flow Restrictor Assembly for the membrane that you have. Find the product
water flow rate in the left-hand column and the length of the flow restric tor in the right-hand column.
Example: If your Flow Restrictor Assembly is for a 90 GPD Membrane and
the product water flow rate is 175 mL/Min, then the flow restrictor
length should be 6 inches (15.2 cm)
4. Using a new single-edge razor blade, carefully measure and then cut the
flow restrictor to the length indicated.
5. 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.

Deionization Cartridge Diagnostic
The DI stage is an anion cartridge #DI-SB-CC-10. In order to determine the condition of the cartridge, watch for the color to change
from the bottom to the top. The color will change from a very dark
blue to a lighter blue or tan color. Once the cartridge has changed
color by 70 to 80% it must be replaced. Failure to replace the DI
cartridge upon exhaustion will contaminate the product water.
(For “down flow” DI systems or systems that incorporate a permeate
pump, the color will change from the top to the bottom ).
Note: If the pH of your tap water is too high, the resin may not
change color.

7. 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.
8. 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.

RO Membrane Replacement
1. Turn off the water supply to the RO system. Place the system where
the membrane housing is easily accessible.
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 (Fig. E).
3. Lift the membrane housing from the retention clips.
4. Unscrew the membrane housing lid. This may require two people.
5. Use a pair of pliers to grasp the membrane stem and pull the
membrane from the housing (Fig. F).
6. Remove the black housing O-ring (Fig. F). Wash the empty housing
with soapy water. Rinse thoroughly with hot, clean water.
7. Insert new membrane into the housing, with the double
O-ring end first (Fig.G). The tube must fit into the recess at the
bottom of the membrane housing. When the membrane is aligned
with the hole, firmly push the membrane into the hole until it
bottoms out.
8. Place the black housing O-ring on the housing rim and carefully
screw the lid back on to the base.
9. Reconnect the black tubing to the membrane feed push-fitting.
Note: If you have a dual-membrane system, perform steps 2 thru 9 on
the second membrane now.
10. Disconnect the yellow concentrate tubing (Fig. B) from the
membrane housing and remove the flow restrictor (Fig. C)

RO Membrane Diagnostic
In order to accurately determine the condition of the RO Membrane, a
conductivity tester capable of reading the tap water conductivity and the
product water conductivity would typically be required.
You may also use an alkalinity test kit (on softened water sources) or a
hardness test kit (cannot be used on softened water sources).
Before performing any membrane test, the DI cartridge must be removed
and the empty housing re-installed; also, the waste -to-product water ratio
must be 4 to 1 or greater.
Procedure:
1. Turn on the system, let it operate long enough to fill the
empty DI housing, then let it run for an additional 20 minutes.
2. See the section on Testing the Quality of the Membrane, page 19.
Perform the test using your chosen method.
3. Turn off the system, drain the DI housing, re-install the DI cartridge,
and turn on the system.
Note: All water sources are different and are subject to changes in
conductivity from season to season which could affect the monitor reading depending on the time of the year. For this reason we recommend
the use of a conductivity tester in order to register the most accurate
measurement for determining the condition of the RO membrane.

Sediment Pre-Filter Diagnostic
For maximum contaminant removal and long membrane life, the sediment and carbon pre-filters must be changed at least 6-month intervals.
**
If your water contains a great deal of sediment or chlorine, the pre-filters
may require more frequent changes to maintain adequate production
rate and extended membrane life.
Sediment Pre-Filter Replacement
Materials Required: 1-micron MicroTec™ Sediment Filter (SF-MT-1-10),
Filter Wrench
Procedure:
1. Turn off water supply to the system.
2.
Refer to Fig. A (System Diagram). Using the provided filter housing
wrench, remove the first housing from the left. Unscrew it coun terclockwise as viewed from the bottom.
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 pre-filter into the housing, screw the housing
back onto the assembly, and tighten securely using the supplied
filter wrench.
6. Proceed with carbon block filter replacement.
**NOTE: A drop in the system’s production is “in most cases” an indication that the sediment and/or carbon filter has become saturated with
contaminants and will need to be replaced.

Carbon Block Filter Diagnostic
Replace the Carbon Block Filter at least every 6 months OR when
chlorine breakthrough greater than 0.1 ppm occurs in the yellow concentrate line**. 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-CL-25. If the chlorine concentration is
above 0.1ppm, replace the carbon pre-filter.
Carbon Block Filter Replacement
Materials Required: 10 micron Carbon Block Filter (CF-10-10),
Filter Wrench, Chlorine Test Kit (TK-CL-25)
Procedure:
1. Turn off water supply to the system.
2.
