MAINTENANCE PROCEDURES
Maintenance and troubleshooting 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.
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 can 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 read-
ing on the (IN PROBE) reads 50% of the left-side meter’s OUT reading, then the MaxCap
®
DI Cartridge needs to
be replaced. When a reading on the (OUT PROBE) is higher than 001 PPM, replace the SilicaBuster Cartridge.
SHELF LIFE FOR FILTERS
PREFILTERS (Sediment and Carbon Block Filters): Prefilters 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). You should
always see moisture inside the bag. If the membrane dries out, it will not produce water and any warranty will
be voided).
DEIONIZING CARTRIDGES (DI)
Replacement DI cartridges are shipped in a Mylar
®
Bag. Keep them in their sealed, original packaging until use.
You can store them for up to 1 year.
SEDIMENT PREFILTER REPLACEMENT:
For maximum contaminant removal and long membrane life, the sediment prefilter must be changed when the system
fails to maintain the preset pressure of 80 PSI. If your water contains a great deal of sediment, the prefilter may require
more frequent changes to maintain adequate production rate and extended membrane life.
Materials Required:
0.2 micron ZetaZorb
®
Sediment Filter (SF-ZZ-0.2-10), Filter Wrench. (Failure to use a
ZetaZorb
®
sediment filter as the 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 prefilter 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.
