CUSTOMER CHECK ACCEPTABLE” basis. In the interim period during which credit  
references are being evaluated, all orders must be shipped “C.O.D. - CERTIFIED  
FUNDS” (cash, cashiers check or money order).  
3. X - Y = 143 ppm  
4. (X - Y) ÷ X = 143 ÷ 150 = 0.953  
5. Rejection = [ ( X - Y) ÷ X ] ×100 = 0.953 ×100 = 95.3  
10. All returned checks (due to insufficients funds or closed accounts) will be  
subjected to a $25 service charge.  
Membrane Hardness Rejection = 95.3 % : Rejection rates less than 95% may  
indicate that the membrane should be replaced.

CHOOSING A MOUNTING LOCATION  
SYSTEM DESCRIPTION  
The MAXCAP DI ™ system is a five stage reverse osmosis de-ionization system.  
When considering a location for the installation of the  
RO System, consider the following factors:  
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 carbon  
block filter to plug.  
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. 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.  
2. Algae is more likely to thrive inside the clear filter housings  
when exposed to bright light.  
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 organics  
above 100 diatoms molecular weight.  
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.  
4. The fourth and fifth stage filter is our MAXCAP DI ™ cartridge followed by  
SpectraPure’s SilicaBuster ™ cartridge.  
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  
The MAXCAP DI ™ system comes equipped with two Dual Inline TDS monitors.  
The first monitor shows TDS levels of pre-and post- RO membrane water. The  
second monitor helps detect the exhaustion points of the DI stages.  
garden hose that may be exposed to sunlight.  
The MaxCap DI™ is used as a “roughing” cartridge followed by our original  
SilicaBuster™ . For example, if the RO water has 25 ppm TDS (Total Dissolved  
Solids) entering a SilicaBuster™ cartridge alone, it may only process about 200  
gallons of pure DI water. By placing a MaxCap DI ™ cartridge in front of the  
SilicaBuster™ cartridge, 600 gallons of water will pass through both cartridges  
before the Max Cap DI ™ is exhausted. The SilicaBuster™ DI cartridge will be only  
one-third exhausted. A second Max Cap DI ™ will process another 600 gallons  
and the SilicaBuster™ cartridge will now be two-thirds exhausted. Only after a  
third Max Cap DI ™ cartridge processes another 600 gallons will the  
SilicaBuster™ cartridge finally become fully exhausted.  
TIPS FOR LONG MEMBRANE LIFE  
1. Replacement of .5 micron sediment filter once every 6  
months. This will prevent membrane fouling due to silt or  
sediment depositing on the membrane.  
2. Replacement of .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 9-10.  
This example illustrates that three Max Cap DI ™ cartridges plus the original  
mixed-bed cartridge will process 1800 gallons of pure DI water. It would have  
taken nine original mixed-bed cartridges to produce the same amount of pure DI  
water.  
4. Operating reverse osmosis systems on softened feed  
water greatly reduces the chances of membrane fouling.  
IMPORTANT NOTE:If you are starting up this system for the first  
time, or replacing either DI cartridge, it is very important that you  
follow the directions on page 8, “System Initialization”.  
5. Use the optional flush valve kit after each use of the system to help  
extend membrane life.

USING THE PRESSURE GAUGE  
The pressure gauge is used to monitor the condition of the Sediment and Carbon  
Pre-Filters. With the Sediment and Carbon filters removed, the gauge will indicate  
the “actual” input water tap water 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 dirt 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 pre-filters 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.

MAINTENANCE  
The maintenance and trouble-shooting procedures have been made easy and  
effective with a combination of the Pressure gauge and two dual Inline TDS  
meters.  
- When there is a pressure drop of 15% of your normal house  
pressure that is an indication that your pre-filters need to be  
replaced.  
- The TDS monitors will let you know when the TDS level rises. All  
our membranes have a 98% rejection. When the TDS level starts  
to rise the % rejection will decrease. You should replace the  
membrane before the % rejection gets to 90%.  
METERING AND DIAGNOSITCS  
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 pre-filters become clogged by dirt [turbidity] from the tap  
water).  
It is highly recommended that one set of Sediment and Carbon  
replacement filters should be on hand and ready for installation as soon as the  
fist monitor indicates that a cartridge change or replacement is required. We do  
not recommend that you have a replacement  
The digital TDS meter (left side) will provide a reliable means of evaluating the efficiency of  
the RO membrane. This meter will indicate the tap water conductivity and the RO water  
conductivity. The difference between the two meter readings will be used to calculate the  
percentage of rejection of the (TFC) RO membrane.  
membrane and DI because they do have a shelf life.  
The Digital TDS meter (right side) will be used to determine the condition of the two stages  
of the DI system. As the reading on the meter begin to increase, the operator will be alerted  
to the possibility that the DI system may have deteriorated past the exhaustion point and  
that the DI cartridges may need to be replaced.  
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).

SYSTEM INITIALIZATION  
If you are setting up your system for the first time or replacing the  
RO membrane, please see the “Checking the Concentrate to  
Purified Water Ratio” .  
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.  
1. IMPORTANT: During the initial rinse-up of the MAXCAP RO/DI ™, a large ionic load is  
presented to the downstream DI cartridges. Be sure to rinse up all new

tubing from the membrane housing and replace the flow restrictor.  
MAXCAP DI ™ with the downstream cartridge removed. This rinsing step will  
ensure that the MAXCAP DI ™ cartridge is initially rinsed up to produce high quality  
water before connecting your downstream cartridge. Failure to rinse this upstream  
MAXCAP DI ™ cartridge may reduce the lifetimeof your downstream DI cartridge.  
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.  
2. Remove the SilicaBuster ™ DI cartridge from the right-most housing and re-install the  
empty housing on the system. Attach garden hose adapter to your cold water source.  
Never run hot water (greater than 100 F (38 C)) through the system.  
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.  
3. Place the yellow concentrate tubing and the blue purified water tubing into a drain or  
bucket. Do not restrict flow from these lines.  
4. Slowly open the cold water supply valve and allow the housings to fill. You may use  
pressure up to 80 psi (5.5 bar). If the pressure is less than 40-PSI, a booster pump will  
be required. If the pressure is greater than 80- PSI, a pressure regulator will be  
required. (See “Optional Items” for the part numbers).

CHECK:  
- Ensure that all fittings are tight and leak-free before leaving the system  
unattended.  
- The concentrate line (yellow) 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 water without the flow restrictor.  
- All of the following conditions must be met before water will flow through the  
system. The water source must be turned “ON” and the water level in the  
reservoir tank must be below the low level float, if present.

CHECKING THE CONCENTRATE TO PURIFIED WATER RATIO  
RO MEMBRANE REPLACEMENT  
This procedure will assure you of maximum life and reliability of your SpectraPure System.  
Failure to perform this procedure can permanently damage the membrane and will void  
the pro-rated Membrane Warranty.  
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).  
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 Puri-  
fied 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.  
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).  
Procedure:  
1. Open the cold water supply valve and let the system run for 15 minutes. Direct  
both tube down the drain.  
6. Remove the black housing O-ring (Fig. F). Wash the empty housing  
with soapy water. Rinse thoroughly with hot, clean water.  
2. Collect product water from the blue tubing into a measuring cup for one minute.  
Measure the collected amount in milli-liters. Do the same with the waste water  
from the yellow line.  
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.  
WASTE (YELLOW) IN MILILITERS______________  
DIVIDED BY  
PRODUCT (BLUE) IN MILILITERS______________  
The resultant is the Concentrate to Product Ratio  
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.  
(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 ).  
Note: If you have a dual-membrane system, perform steps 2 thru 9 on  
the second membrane now.  
3. If ratio is less than 4:1  
Disconnect yellow drain line from the membrane housing and then remove flow restrictor.  
Use the appropriate Flow Restrictor Chart to determine how long to cut the flow restrictor  
in order to obtain a 4:1 ratio. ( Figure B)  
10. Disconnect the yellow concentrate tubing (Fig.C) from the  
membrane housing and remove the flow restrictor (Fig. D) from the  
yellow tubing (Refer to the procedure on page 11-12).  
* Please refer to pages 11-12 for Flow Restrictor Removal, Adjustment, and Replacement. *

RO MEMBRANE DIAGNOSTICS  
Although RO membranes are capable of maintaining high water quality  
over extended periods of time they eventually will begin to deteriorate.  
Normally, the conductivity of the permeate water will increase as the  
membranes age. By comparing the difference in TDS readings between  
the Tap water conductivity and the RO water conductivity, the per-  
centage of rejection of the RO membrane may be calculated and the  
resultant number may then be used to determine the condition of the  
membrane and thus the operator will know when the membrane needs  
to be replaced. Membrane failure will be indicated by a reduction of the  
percentage of rejection which will be determined by calculating the dif-  
ferential between the input and output numbers.

In order to accurately determine the condition of the RO Membrane, a  
conductivity tester (TDS meter) capable of reading the tap water  
conductivity and the permeate water conductivity has been provided  
with this system. With the assistance of the TDS meter you will be able to  
easily determine the RO membrane’s condition. (see page 7)

Before performing the diagnostic test on the RO membrane, make sure  
that the RO system has been “ON” and producing pure water for a mini-  
mum of 10 minutes. Also check the brine (yellow) line to make sure that  
water is flowing and that the flow ratio between the permeate water  
and the brine water is at a ratio that is > 4 to 1. ( See Page 9). (NOTE: The  
pressure gauge should indicate a pressure reading of > 40 PSI during this  
15-20 minute test period.

FLOW RESTRICTOR REMOVAL, ADJUSTMENT  
AND REPLACEMENT  
MAXCAP RO/DIMAINTENANCE AND REPLACEMENT  
Procedure:  
1. Locate the yellow concentrate tubing (Fig. C ). Remove the tubing from its push-fitting  
at the membrane as follows:  
1. When the reading on the right-hand TDS meter (set to “IN”) displays 75%  
of the reading on the left-hand TDS meter (set to “OUT”), it is time to  
replace the MAXCAP DI cartridge.  
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. Follow the directions on page 8 to replace the MAXCAP DI ™  
cartridge.  
3. Make sure the DI cartridge is installed in the correct direction as marked  
on the cartridge shell and be sure that the top seal is securely attached to  
the top of the cartridge.  
4. Tighten the cartridge housing by rotating it clockwise and hand tighten.  
5. Turn on system and check for leaks.  
SilicaBusterMAINTENANCE AND REPLACEMENT  
2. Carefully remove the flow restrictor assembly, now visible as a plastic insert In the end  
of the yellow tubing (Fig. D). 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 coller and thin capillary tubing) may then be gently extracted.  
Procedure:  
1. When the reading on the right-hand TDS meter (set to “OUT”) displays  
Note: Take care not to crush or otherwise damage the delicate capillary tubing.  
“001”, it is time to replace the SilicaBuster  
DI cartridge.  
3. Refer to the Flow Restrictor Tables (Fig. B). Find the table that represents the  
Flow Restrictor Assembly for the system that you have. Find the product  
flow rate in the left-most column and the length of the flow restrictor in the  
right-most column.  
2. Follow the directions on page 8 to replace the SilicaBuster  
DI cartridge.  
3. Make sure the DI cartridge is installed in the correct direction as marked  
on the cartridge shell and be sure that the top seal is securely attached to  
the top of the cartridge.  
Example: If your Flow Restrictor Assembly is for a 150 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. Tighten the cartridge housing by rotating it clockwise and hand tighten.  
5. Turn on system and check for leaks.  
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:  
SEDIMENT PRE-FILTER REPLACEMENT  
For maximum contaminant removal and long membrane life, the sediment  
pre-filter must be changed when a 15-20% drop in pressure is observed OR at  
least 6-month intervals. If your water contains a great deal of sediment the  
pre-filter may require more frequent changes to maintain adequate production  
rate and extended membrane life.  
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.  
Sediment Pre-Filter Replacement  
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.  
Materials Required: 0.5-micron MicroTec™ Sediment Filter (SF-MT-0.5-10),  
Filter Wrench  
Procedure: (FIRST FILTER ON LEFT)  
1. Turn off water supply to the system.  
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 reseat the tubing as described above.  
2. Refer to photo on page 6. Using the provided filter wrench, remove  
the first housing on the left. Unscrew it counterclockwise as viewed  
from the bottom.  
3. Remove the old filter and discard.
