-- HOW YOUR REVERSE OSMOSIS SYSTEM WORKS --

PREFILTER

Water from the cold supply pipe enters the RO as- sembly prefilter first (FIG. 8 and schematic below).

The prefilter has a replaceable sediment cartridge with activated carbon in its composition. The car- tridge (10 micron) removes sand, silt, dirt, other sedi- ments, and up to the ppm of chlorine shown in the specifications from the feed water. Chlorine will de- stroy the RO membrane. Filtered, clean, chlorine- free water flows from the prefilter, to the RO mem- brane cartridge.

IMPORTANT: See prefilter maintenance, page 11.

product water. Taste- free, odor- free, clean, high quality drinking water is available for use.

FAUCET

The sink or countertop faucet has a hand operated, spring- loaded closed lever to prevent the waste of drinking water. You can also keep the faucet open by pushing upward on the lever and locking it against the faucet spout.

To comply with plumbing codes, an air- gap is built into the faucet drain water connection.

SHUTOFF ASSEMBLY

REVERSE OSMOSIS (RO) CARTRIDGE

The cartridge inside of the RO housing, is a tightly wound, special membrane. Water is forced through the cartridge and the membrane removes the dis- solved solids and organic matter. High quality prod- uct water (about 1 ounce per minute) exits the RO housing and goes to the storage tank, or to the post- filter and RO faucet. Reject water, with the dissolved solids and organic matter, is routed through the flow control and to the drain.

STORAGE TANK

The storage tank holds up to 2.3 gallons of product water. A diaphragm inside the tank keeps water pressurized to about 30 psi, when the tank is full, to provide fast flow from the RO faucet. The tank, when empty, is pressurized to 5 - 7 psi.

POSTFILTER

After leaving the storage tank, but before going to the RO faucet, product water goes through the postfilter. The postfilter is an activated carbon type filter. Any remaining tastes and odors are removed from the

To conserve water, the drinking water system has an automatic shutoff system. When the storage tank has filled to capacity, and the drinking water faucet is closed, pressure closes the shutoff to stop flow into the RO. Pressure in the storage tank is about half of the water supply pressure. After drinking water is used, and pressure in the system drops, the shutoff opens to allow water flow again.

CHECK VALVE

A check valve (FIG. 10) is located in the outlet end of the RO housing, opposite of the cap. The check valve prevents a backward flow of product water from the storage tank. A backward flow could rupture the RO membrane.

FLOW CONTROL

Water flow through the RO membrane is regulated by the flow control. It maintains the desired flow rate to obtain the highest quality drinking water. The flow control is located in the end of the 1/4”red drain tubing, at the RO housing drain port. A small cone- shaped screen fits over the end of the flow control to help prevent plugging with drain water sediments.
