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.
The system includes an electronic faucet assembly with a prefilter and postfilter change reminder. When six months have passed, a
flashing light will remind you to change the two filters.
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
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
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
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.
7
Flow Control
The flow control regulates the flow of water through the Reverse Osmosis
line exiting off the manifold.
8
Faucet and Electronics
It 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 to remind you when it is time to replace your prefilter and postfilter. Replace the
filters when the light begins to flash in order to protect the RO membrane and keep the system functioning properly.
