About the reverse osmosis system.
How the Reverse Osmosis System Works
Reverse Osmosis reduces Total Dissolved Solids (TDS) and organic matter from water by diffusing it through a special membrane (see
Performance Data Sheet). 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.
These systems include an electronic faucet assembly with a prefilter and postfilter change reminder, Reverse Osmosis membrane change
reminder and a status okay reminder.
The prefilter and postfilter change reminder will flash amber after six months have passed or 900 gallons have been used. When this occurs, it
is time to replace these cartridges and sanitize the system.
The membrane change reminder flashes amber when the TDS monitor in the system has measured the amount of impurities removed is less
Finally, a green flashing light will indicate the system is functioning properly.
Description of the Reverse Osmosis System
1
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 taste and odor 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.
2
Reverse Osmosis Cartridge
special membrane. Water is forced through the cartridge where the membrane
reduces the dissolved solids and organic matter. For the reduction of the claims
specified, see Performance Data Sheet. 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
" tubing.
3
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.
4
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.
5
Check Valve
The check valve prevents a backward flow of product water
from the storage tank. A backward flow could cause the Reverse Osmosis
membrane to rupture.
6
Automatic Shutoff Assembly
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.

Flow Control

The flow control regulates the flow of water through the Reverse Osmosis cartridge at
the required rate to produce high quality water. The control is located in the 1/4" drain line exiting off the
manifold.
8
Faucet and Electronics
has a hand-operated lever, with variable flow adjustment. You can keep the faucet open by removing
your hand from the lever once water is flowing. To comply with plumbing codes, an air gap is built into
the faucet drain water connection.
The electronic faucet provides a six month timer and flow monitor to remind you when it is time to
replace your prefilter and postfilter. Replace these when the amber filter light flashes. The faucet also
provides an amber RO light indicating when the Reverse Osmosis cartridge is no longer filtering out at
