About the reverse osmosis system.

What the Reverse Osmosis System Does

Reverse Osmosis removes 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. 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; see Specification Guidelines. How much it makes depends on the feed water supply pressure, temperature and quality.

The carbon prefilter and postfilter are replaceable cartridges. The prefilter removes chlorine while also filtering sediments. The postfilter removes any other undesirable tastes and odors before you use the water.

Description of the Reverse Osmosis System

Installation Instructions Operating Instructions Safety Instructions

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

3 gallons of product water. A diaphragm inside the tank keeps water pressurized 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. 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 Valve—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.
