HOW Your Reverse Osmosis System Works

Introduction: Your Reverse Osmosis (RO) Drinking Water System uses your household water pressure to force water through three filters. Minerals and impurities are filtered out. Delicious tasting drinking water goes to the storage tank-ready for your use. Minerals and impu- rities are sent down the drain. The following paragraphs will explain in detail how your Reverse Osmosis Drinking Water System works.

Prefilter: Water from the cold supply pipe enters the pre- filter. See Figure 24. The prefilter has a replaceable sedi- ment cartridge with activated carbon in its composition. The cartridge reduces taste, odor, sand, silt, dirt, other sediments, and up to the amount of chlorine shown in the specifications.

Reverse Osmosis Cartridge: Filtered water flows from the prefilter, to the Reverse Osmosis membrane car- tridge. See Figure 24. The Reverse Osmosis cartridge is a tightly wound special membrane. The membrane

reduces the dissolved solids and organic matter. High quality product water (about one ounce per minute) exits the Reverse Osmosis cartridge. The product water flows to the storage tank, postfilter or Reverse Osmosis faucet. See Figure 24. Reject water, with the dissolved solids and organic matter, is routed to the drain. See Figure 24.

Storage Tank: The storage tank holds product water. See Figure 24. A diaphragm inside the tank holds water pres-

surized to about 30 psi when the tank is full. This pro- vides fast flow to the Reverse Osmosis faucet. When the

tank is empty of water, it is pressurized to 5 - 7 psi.

Postfilter: Before going to the Reverse Osmosis faucet, product water goes through the postfilter. See Figure 24. The postfilter is an activated carbon type filter. Any remaining tastes and odors are reduced from the prod- uct water. Clean, high quality drinking water is available at the faucet.

Reverse Osmosis Faucet: The sink or countertop faucet has a hand operated knob to access drinking water. See Figure 24. An air-gap is built into the faucet drain water

connection to comply with plumbing codes. See Figure 24.

Faucet Electronics: The RO system will monitor the total

product flow of the unit and also length of time the fil- ters have been installed. The faucet base has an indicator

light that flashes to inform you of the status of the RO membrane and filters.

Green - RO membrane and filters are good.

Amber - Warning, filters need replacing. Filters need replacing, when water has been drawn, after 6 months time (or 650 gallons have been used).

Red - RO membrane needs to be replaced.

Shutoff Assembly: The unit has an automatic shutoff system to conserve water. When the storage tank has filled to capacity, and the drinking water faucet is closed, pressure closes the shutoff to stop flow to the drain.

After enough drinking water is used, pressure in the sys- tem drops, and the shutoff opens to allow the tank to be refilled. See Figure 24.

Check Valve: A check valve is located in the Reverse Osmosis manifold, above the center sump. The check valve prevents a backward flow of product water from the storage tank to drain. A backward flow could dam- age the Reverse Osmosis Membrane. See Figure 24.

Flow Control: Water flow to the drain is restricted 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 Reverse Osmosis manifold drain port. See Figure 24.
