MAINTENANCE PROCEDURES
Maintenance and troubleshooting procedures have been made easy and effective with a combination of the two dual-
probe 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 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:
0.5
micron MicroTek™ Sediment Filter (SF-MT-0.5-10), Filter Wrench.
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.
SHELF LIFE FOR FILTERS:
PREFILTERS (Sediment & Carbon Block Filters): Prefilters have an infinite shelf life.
REVERSE OSMOSIS (RO) MEMBRANE: 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 it 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.
DEIONIZATION (DI) CARTRIDGES: 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.
