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.

TIPS FOR LONG MEMBRANE LIFE

1.   Replacement of .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 .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.

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 help
 

  extend membrane life.

SYSTEM DESCRIPTION

The 

M

AX

C

AP

 DI ™ system is a five stage reverse osmosis de-ionization 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 carbon   

 

 

 

 

block filter 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 

 

98% of most inorganic salts, all micro-organisms and organics    

 

 

 

 

above 100 diatoms molecular weight. 

4.  The fourth and fifth stage filter is our 

M

AX

C

AP

 DI ™ cartridge followed by   

 

 

SpectraPure’s SilicaBuster ™ cartridge.

The 

M

AX

C

AP

 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.

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.

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.
