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 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 1.3 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—
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—
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 drain water.
To conserve water, the drinking water system has an automatic shutoff. When the storage
