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
reduces sand, silt, dirt, other sediments and up to
2.0 ppm of aesthetic chlorine from the water. The
prefilter reduces chlorine in the water because
CHLORINE DESTROYS THE REVERSE OSMOSIS
MEMBRANE. Filtered, clean, aesthetic 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.
What the Reverse Osmosis System Does
Reverse Osmosis removes Total Dissolved Solids
(TDS) and other contaminates, as specified on page
3, from the water by diffusing it through a special
membrane. 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
water supply pressure, temperature and quality. The carbon prefilter and postfilter are replaceable
cartridges. The prefilter reduces chlorine taste and
odor while also filtering sediments. The postfilter
reduces any other undesirable taste and odors
before you use the water.
