Enduro DI™ cartridge. These DI cartridges work in tandem to achieve a greatly extended lifespan when compared to standard mixed-bed DI cartridges. Because the RO water reaches it first, the Mega MaxCap™ will need to be replaced more often than the Enduro DI™. The Mega MaxCap RODI system comes equipped with two Dual-Probe ™... -
Page 6: General System Description
A pressure - operated Automatic Shutoff (ASO) Valve and a Float Valve are provided for convenient filling of a storage reservoir. NOTE: SpectraPure does not recommend using the Float Valve for topoff due to evaporation. The short duration of the fill cycle when using a float valve will rapidly deplete the life of the DI cartridges due to TDS creep. -

Page 10: Cautions
SpectraPure ® CAUTION • 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. • Avoid installing this unit in an area where it may be subjected to bright light or direct sunlight, as algae is more likely to thrive inside the clear filter housings when exposed to bright light. -

18. 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.) 19. It may take several days of normal operation for the membrane to reach its full production rate. -
Page 12: Float Valve Illustration
SpectraPure ® FLOAT VALVE ILLUSTRATION: HOW THE FLOAT VALVE WORKS: The increasing water level raises the Float Valve in the reservoir and stops the flow of water. Pressure builds up in the product line and ASO Valve until the ASO Valve shuts off the flow of waste water to drain. This “OFF”... -

Page 14: Using The Pressure Gauge
SpectraPure ® USING THE PRESSURE GAUGE: The pressure gauge is used to monitor the condition of the Sediment and Carbon Prefilters. With the Sediment and Carbon filters removed, the gauge will indicate the “actual” tap water input pressure. When the prefilters are “new”, the pressure shown on the gauge will be slightly less than the... -
Page 15: Testing The Quality Of The Membrane
SpectraPure ® 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). Use the TDS Meter located on the left side of your system for this procedure. -
Page 16: Membrane Production Calculation
SpectraPure ® MEMBRANE PRODUCTION CALCULATION: Membranes produce the rated gallons per day (GPD) at 60 psi (4.1 bars) operating pressure, 77°F (25°C) operating temperature and with no more than 250 ppm total dissolved solids. Membrane output gallons per day (GPD) depends on operating pressure, water temperature and the TDS in the feed water. -

Page 18: Working With Push Fittings
SpectraPure ® WORKING WITH PUSH FITTINGS: Push fittings are very reliable and convenient tubing connectors. To remove the tubing from its push fitting: 1. Firmly depress and hold the push fitting collar down with your thumbnail. 2. While the push fitting collar is depressed, pull the tubing straight out of the push fitting. -
Page 19: Sediment Prefilter Replacement
SpectraPure ® SEDIMENT PREFILTER REPLACEMENT: A Sediment Filter will usually last approx. 4 -6 months, depending on the quality of the tap water and quantity of water being produced. (The lifespan of the filter is determined by the turbidity, iron content, organics, and total particulate volume in your water source). -
Page 20: Carbon Block Filter Replacement
SpectraPure ® CARBON BLOCK FILTER REPLACEMENT: A Carbon Filter will usually lasts 4-6 months, depending on the chlorine (or chloramine) content of your tap water and quantity of water being produced. The best way to determine when your Carbon Block Prefilter needs to be replaced is to use a chlorine test kit. -

® MEGA MAXCAP DI REPLACEMENT: The Mega MaxCap™ DI cartridge is located in the second housing from the right. When the Right-Side Meter (set to the “IN” position) reads “1”, it is time to replace the Mega MaxCap™ DI cartridge. -
Page 22: Ro Membrane Replacement
SpectraPure ® RO MEMBRANE REPLACEMENT: Your Mega MaxCap system comes equipped with a SpectraSelectPlus™ 99% rejection membrane. As membranes age, their rejection rates drop. The DI cartridges scrub all of the TDS from the water that the RO membrane does not remove. -

SpectraPure ® RO MEMBRANE REPLACEMENT: (continued) 7. Place the black housing O-ring on the housing rim and carefully screw the lid back on to the base. Hand-tighten. 8. Reconnect the black tubing to the membrane feed push fitting. 9. If you have a dual-membrane system (-180), perform steps 2 thru 8 on the second membrane. -
