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 2.1 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.
Check Valve—
A check valve is built into one end of the Reverse Osmosis housing under the tee fitting. 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 Assembly—
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.

Reverse Osmosis Cartridge—
The cartridge, inside the Reverse Osmosis housing, includes a tightly wound, special
membrane. Water is forced through the cartridge where the membrane removes the dissolved solids and organic
matter. High quality product water exits the Reverse Osmosis housing and goes to the storage tank. Reject water, with
the dissolved solids and organic matter, leaves the housing 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
which is inside the sump. The postfilter is also a replaceable sediment cartridge that contains activated carbon. Any
remaining tastes, odors, or sediments are removed from product water by the postfilter. Clean, high quality
drinking water flows through the tubing and to the system faucet.
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 elbow fitting at the Reverse Osmosis housing drain
port. A small, cone-shaped screen fits over the front end of the flow control to prevent clogging due to sediments in
the drain water.
