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 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.

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 MAXCAP 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 MAXCAP DI ™ cartridge followed by SpectraPure’s SilicaBuster ™ cartridge.

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.

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”.
