Description of the Reverse Osmosis System
Prefilter—Water from the cold supply pipe is
directed to the prefilter cartridge, which is inside
the sump. The prefilter is a replaceable sediment
cartridge containing activated carbon. The
cartridge removes sand, silt, dirt, other sediments
and up to 2.0 ppm of chlorine from the feed
water. The prefilter reduces chlorine in the feed
water because CHLORINE DESTROYS THE REVERSE
OSMOSIS MEMBRANE. Filtered, clean, chlorine-
reduced water flows from the prefilter to the
Reverse Osmosis cartridge.
Storage Tank—The storage area holds up to
3 gallons of product water. A diaphragm inside
the tank keeps water pressurized for fast flow
to the faucet when drinking water is needed.
Check Valve—A check valve is built into one end
of the Reverse Osmosis housing. The check valve
prevents a backward flow of product water from
the storage area. A backward flow could cause the
Reverse Osmosis membrane to rupture.
Automatic Shutoff Valve—To conserve water, the
drinking water system has an automatic shutoff.
When the storage tank has filled to capacity and
the drinking water faucet is closed, pressure closes
the shutoff. Water flow to the Reverse Osmosis
housing is shut off until drinking water is used
again, and pressure drops in the Reverse Osmosis
system.

About the reverse osmosis system.
What the Reverse Osmosis System Does
Reverse Osmosis removes Total Dissolved Solids
(TDS) and organic matter from water by diffusing
it through a special membrane. The membrane
separates minerals and impurities from the water
and they are flushed to the drain. High quality
product water goes directly to the drinking water
faucet or to the storage tank. The system makes
a good supply of drinking water each day; see
Specification Guidelines. How much it makes
depends on the feed water supply pressure,
temperature and quality. The carbon prefilter and postfilter are replaceable
cartridges. The prefilter removes chlorine while
also filtering sediments. The postfilter removes any
other undesirable tastes and odors before you use
the water.
