WHAT IS REVERSE OSMOSIS?

Osmosis is a process in nature that allows fluid of a lower concentration to pass through a
semi-permeable membrane into a fluid of a higher concentration (See Figure 1). Because of
the difference in salt concentration, pure water flows through the membrane as though a
pressure were being applied to it (Figure 2). The effective driving force is called the osmotic
pressure. As a rough guide, the osmotic pressure is equal to about 1 psi (pounds per square
inch) per 100 ppm Total Dissolved Solids (TDS). When enough pressure is applied to the
solution with a higher concentration it can then pass through the membrane into the
solution of lower concentration. (See Figure 3). This is the basis of Reverse Osmosis.

Figure 1 Figure 3

Household water pressure is used to force tap water through the semipermeable R.O.
membrane. The membrane only allows the purest of water molecules to pass through
it while over 98% of most salts and other impurities are rejected and automatically
rinsed from the membrane down the drain.

Figure 2

WHAT DOES THE SYSTEM DO?

SpectraPure’s MPRO™ RO System uses household water pressure to reverse a natural
physical process called osmosis. Water, under pressure is forced through a semi-permeable
membrane where minerals and impurities are screened out and sent down the drain with
waste water. These minerals and impurities are measured as total dissolved solids (TDS).

The system connects to a house COLD water pipe for a water supply. The system includes
replaceable sediment, carbon pre-filters and a membrane. The sediment pre-filter removes
sand, dirt, rust particles and other particulates while the carbon pre-filter takes chlorine and
organics out of the feed water. The water then passes through the RO membrane.

The MPRO™ System gives you a continuous supply of sparkling clear, delicious water for
drinking, cooking, hydroponics etc. Foods will look better and taste better too. The reliability
with the MPRO™ Water Treatment System is greatly improved over other systems and costly
maintenance is avoided. The system eliminates the need to buy bottled water. Instead, it
puts high quality water at your fingertips.

SYSTEM DESCRIPTION:

The MPRO™ RO System is a three stage reverse osmosis system.

1. First, the incoming feed water is passed through a 0.5 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 0.5 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 96% of most inorganic
salts, all micro-organisms and almost all high molecular weight organics in
the water.

Product Water Ratio” procedure on page 10 after you do system
hook-up below.

System Hook-Up

1. Attach the garden hose adapter (connected to the black tubing) to

your cold water source. Never run hot water (greater than 100° F
(38° C)) through the system.

2. Place the yellow concentrate (waste) tubing and the blue purified

(product) water tubing into a drain. Do not restrict flow from these
lines.

3. Open the cold water supply valve. You may use pressure up to 80 psi

(5.5 bar).

lease follow the “

Measuring Waste to

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 is recommended that at least 2 gallons (7.57 liters) of purified
water be discarded now before collecting purified water for use. If the
unit is not used for several days, run the system for at least 10 minutes
before collecting any water. This will flush out any stale water in the
system.

4. Now follow procedure on page 10 to adjust the Flow Restrictor.

5. Finish the installation by connecting the yellow line to a drain. The

blue line can be placed into a Rubber Maid™ trash can or set up to
become automatic using a Liquid Level Controller (LLC-S-115 ),
(LLC-M-115) or the Auto Shut-Off Kit (ASOFK).

SpectraPure®Inc. Assumes no responsibility for water

damage due to leaks. It is the user’s responsibility to determine

that the system is leak-free.

MEASURING WASTE TO PRODUCT WATER RATIO.

This procedure will assure you of maximum life and reliability of your SpectraPure
System.

membrane and will void 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. Collect product water (blue tubing) into a measuring cup for one minute.
(Measure the collected amount in milli-liters). Do the same with the waste
water (yellow tubing):

Failure to perform this procedure can permanently damage the

WASTE (YELLOW) IN MILLILITERS______________

DIVIDED BY

PRODUCT (BLUE) IN MILLILITERS______________

The resultant is the Concentrate to Product Ratio

(Although not needed in this procedure, the daily product flow rate in Gallons per

Day (GPD) can be calculated to be equal to the product flow rate times 0.38 ).

2. If ratio is less than 4/1:
Disconnect yellow drain line from the membrane housing and remove
flow restrictor (page12-13). Use the appropriate Waste to Product ratio
chart (Fig D) to determine how long to cut the flow restrictor in order
to obtain a 4:1 ratio.

EXAMPLE: If you have a 90 GPD unit (FR-90), and your product flow is
175 ml/.min, than the flow restrictor needs to be cut to a total length
of 6 inches (15.2 cm)

3. If ratio is greater than 6:1, flow restrictor requires replacement
(Please contact SpectraPure Inc).

.

This completes the procedure

FLOW RESTRICTOR REMOVAL, ADJUSTMENT
AND REPLACEMENT

1. Locate the yellow concentrate tubing (Fig. B for Single-Membrane System or
Fig. C) for Dual-Membrane System). 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. E). 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 collar 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 system that you have. Find the product

flow rate in the left-hand column and the length of the
flow restrictor in the right-hand column.

Example: If your Flow Restrictor Assembly is for a 90 GPD Membrane and
the product flow rate is 170 mL/Min, then the flow restrictor length should
be cut to 6.5 inches (16.5 mm). 170 is about halfway between 164 (7 in.)
and 175 (6 in.).

4. Using a new single-edge razor blade, carefully measure and then cut the
flow restrictor to the total 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.

6. 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.

7. 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 re-seat the tubing as
described above.

SEDIMENT PRE-FILTER REPLACEMENT:

A Sediment Filter will usually last approx. 4-6 months, depending on micron
rating and quality of water. (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 Pre-Filter needs
replacement is to the a Pressure Gauge. When you have a drop in pressure
between 15-20% from where your normal house pressure is, replace filter. To
check this, run water through the system without the filter in it’s housing. If the
pressure jumps back to your normal house pressure without the filter, you know
the filter you just took out was plugged up.

**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.

Sediment Pre-Filter 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.
wrench, remove the first housing on the left. Unscrew it
counterclockwise 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 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.

** 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.

CARBON BLOCK FILTER REPLACEMENT:

A Carbon Filter will usually lasts approx. 4-6 months ,depending on micron
rating for the filters, usage and the quality of your tap water. The best way to
determine when your Carbon Block Pre-Filter 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-CL-25. If the
chlorine concentration is above 0.1ppm, replace the carbon pre-filter.

**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 drop production, if its 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: 0.5 micron Carbon Block Filter (CF-0.5-10),
Filter Wrench, Chlorine Test Kit (TK-CL-25)

Procedure:

1. Turn off water supply to the system.

2.

Refer to Fig. A (System Diagram). Using the provided filter housing
wrench, remove the second housing from the left.
Unscrew it counterclockwise 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 carbon block filter, making sure that
the black gaskets on both ends of the filter are firmly
seated in the gasket recesses.

6. 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.

RO MEMBRANE DIAGNOSTICS:

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 waste -to-product water ratio
must be 4 to 1 or greater.

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.

MEMBRANE WARNING: All SpectraPure RO membranes, except
for encapsulated membranes, must remain moist at all times. It
is the customer’s responsibility to inspect the membrane upon
receipt and maintain adequate moisture.

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

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 (Page 12).

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. G).

6. Remove the black housing O-ring (Fig. G). 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. F) from the
membrane housing and remove the flow restrictor (Fig. E)

Place the flow restrictor in a safe location where it will not be
accidentally crushed or damaged.

11. Put the yellow concentrate tubing and the blue product
water tubing in the drain and turn on the system water supply.
Allow the system to flush for several minutes to remove any loose
particles.

12. Turn off the water supply to the system. Remove the yellow
tubing from the membrane tubing from the membrane housing
and replace the flow restrictor assembly as described on page 12-13.

13. Re-insert the flow restrictor end of the yellow tubing into
its push-fitting at the RO membrane and reconnect the yellow
concentrate tubing to the membrane housing.

14. Turn on the water supply to the system and check for leaks. Check,
and if necessary adjust, the Concentrate to Purified Water Ratio per
the procedures described in that section.

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 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.

Temperature Correction Factor Table (TCF)

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.

TIPS FOR LONG MEMBRANE LIFE:

1. Replacement of 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. Replacement of 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. Membrane should not be operated at lower than the
recommended concentrate to purified water ratios, as
described on page 10-11.

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

5. Use the optional flush valve kit 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).

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.
