MAINTENANCE REGIMEN
Maintenance and trouble-shooting procedures have been made easy and effective with a combination of the (2) Dual TDS
meters and a built-in pressure gauge. It is recommended that you keep replacement cartridges on hand, ready to install as
soon as the monitor indicates that the cartridge in use is exhausted.
SEDIMENT PRE-FILTER REPLACEMENT:
For maximum contaminant removal and long membrane life, the sediment pre-filter must be changed when the system
fails to maintain the pre-set pressure of 100 PSI. 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.
Materials Required:
0.2-micron Zeta-Zorb™ Sediment Filter (SF-ZZ-0.2-20), Filter Wrench.
(Failure to use a
Zeta-Zorb sediment filter for replacement will void the system’s warranty.)
Procedure:
(FIRST FILTER ON LEFT)
1. Turn off water supply to the system.
2. 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.
4. Thoroughly wash the housing with a mixture of hot soapy water and a few teaspoons of household
bleach. Rinse well with clean hot water.
5. Install the new pre-filter into the housing, Screw the housing back onto the assembly, and
hand tighten
only
.
NOTE: Do not use filter wrench to tighten housings. Over-tightening will damage housings
and void your warranty.
6. Proceed with carbon block filter replacement.
METERING AND DIAGNOSTICS:
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 (IN PROBE) and the RO water conductivity (OUT PROBE).
The difference between the two meter readings will be used to calculate the percentage rejection of the
(TFC) RO membrane. (as shown on page 12)
The Digital TDS meter (right side) will be used to determine the condition of the two DI stages. When the
reading on the (IN PROBE) reads 50% of the first meter’s OUT reading, then the MaxCap Cartridge needs to be
replaced. When a reading on the (OUT PROBE) is higher than 1 PPM, replace the Silica-Buster Cartridge
SHELF LIFE FOR FILTERS:
PRE-FILTERS (Sediment & Carbon Block Filters): Pre-Filters have an infinite shelf life.
REVERSE OSMOSIS MEMBRANE (RO:) Purchase an RO membrane when needed. If you would like to keep one on
hand, you can store it in the refrigerator for up to 1 year. (Keep in its sealed, original packaging). If the membrane
dries out, it will not produce water and any warranty will be voided).
DE-IONIZING CARTRIDGES (DI)
Replacement DI cartridges come shipped in a Mylar® Bag. Keep them in their sealed, original packaging until use.
You can store it for up to 1 year.
