About the reverse osmosis system.
How the Reverse Osmosis System Works
Description of the Reverse Osmosis System
Reverse Osmosis reduces 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. For the
reduction of the claims specified, see Performance Data Sheet. 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. How much it makes
depends on the feed water supply pressure, temperature and quality.
The prefilter and postfilter are replaceable cartridges. The carbon prefilter reduces chlorine while also filtering sediments.
The postfilter reduces any other undesirable tastes and odors before you use the water.
The system includes an electronic faucet assembly with a prefilter and postfilter change reminder. When six months have
passed, a flashing blue light will remind you to change the two filters.

Operating Instructions
Prefilter— Water from the cold supply pipe is directed to the
prefilter cartridge. The prefilter is a replaceable sediment
cartridge containing activated carbon. 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.
Reverse Osmosis Cartridge— The middle cartridge includes a
tightly wound, special membrane. Water is forced through the
cartridge where the membrane reduces the dissolved solids and
organic matter. High quality product water exits the Reverse
Osmosis cartridge and goes to the storage tank. Reject water,
with the dissolved solids and organic matter, leaves the cartridge
and is discharged to the drain through 1⁄4
″ tubing.
Postfilter— After leaving the storage area, but before going
to the system faucet, product water goes to the postfilter
cartridge. The postfilter is also a replaceable sediment cartridge
that contains activated carbon. Any remaining tastes, odors or
sediments are reduced from product water by the postfilter.
Clean, high quality drinking water flows through the tubing
and to the system faucet.
Storage Tank— The storage area holds up to 2-1/2 gallons
of product water. A diaphragm inside the tank keeps water
pressurized, when the tank is full, for fast flow to the faucet
when drinking water is needed.
