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.
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”.
