- HOW TO INSTALL YOUR HOME DRINKING WATER SYSTEM -
the RO system. At that time, carefully check all fit­
tings and tubing connections for any water leaks.
Correct leaks if any are found.
E. IMPORTANT PURGING INSTRUCTIONS:
The RO cartridge contains a food grade preser­
vative that you should clean from it before using
the system. The preservative wtil give product water
an unpleasant taste and odor.
1. After the storage bladder has filled (takes about
4 hours), open the system faucet until the bladder
is empty.
2. Allow the bladder to fill again for about 4 hours,
then open the faucet and empty. After 4 purgings,
the system is ready to make product water for your
use.
- HOW YOUR HOME DRINKING WATER SYSTEM WORKS -
Water from the cold supply pipe saddle valve is
directed through 1/4" tubing, to the electronic box.
Here, the total dissolved solids (TDS) content, of
the supply water, is measured. Water flow continues
to the RO prefilter.
PREFILTER - The prefilter is a replaceable
sediment-activated carbon cartridge. It removes
sand, silt, dirt, other sediments, and up to 2 parts
per million (ppm) chlorine from the supply water.
CHLORINE WILL DESTROY THE RO MEM­
BRANE ... SEE PAGES 4 AND 13. Filtered, clean,
chlorine-free water flows from the prefilter and to
the RO membrane.
RO MEMBRANE CARTRIDGE - The RO car­
tridge, located inside of the prefilter, is a tightly-
wound,
semi-permeable membrane. Semi­
permeable means water will work through the mem­
brane, but first, dissolved solids and organic mat­
ter are screened out and flushed to the drain. The
screened, high quality product water goes to the
storage area, or to the postfilter if the RO faucet
is open.
POSTFILTER - After leaving the storage area, but
before going to the faucet, product water goes
through the postfilter. The postfilter is also a
sediment-carbon type filter. It removes any remain­
ing tastes, odors or sediments from the product
