The Reverse Osmosis membrane is a specially constructed, fully aromatic polyamide film, and is classified as a Thin Film Composite (T.F.C.). The spiral wound construction of the Reverse Osmosis Membrane provides maximum surface area for water production and is less susceptible to fouling by particulate matter, turbidity and colloidal materials. INTRODUCTION Your new Reverse Osmosis Drinking Water System uses a combination of filtration technologies to reduce unwanted contaminants in your water supply.
REVERSE OSMOSIS PREPARATION A. Reverse Osmosis Major System Components The following components comprise the Reverse Osmosis Drinking Water System. (Refer to Fig. 1, below for general system layout.) 9. Reverse Osmosis Sediment Pre-filter, shrink wrapped. 10.Reverse Osmosis activated Carbon Prefilter, shrink wrapped. 11.Reverse Osmosis In-Line Activated Coconut Shell Carbon Post Filter. 12.

C. Site Selection for Major System Reverse Osmosis Components B. Tools Recommended for Reverse Osmosis Installation The following tools will cover most of the Reverse Osmosis installation sites encountered: The Reverse Osmosis System was designed to fit under a sink, however, because of space limitations or other reasons, the Reverse Osmosis system's flexible design allows for other locations.
2b. Drilling a porcelain sink: 4. Reverse Osmosis Feed Water Connection – The Reverse Osmosis Feed Water Ball Valve should be located as close to the manifold assembly as possible. USE A POTABLE COLD WATER SUPPLY ONLY TO YOUR REVERSE OSMOSIS SYSTEM. Softened water is preferred as it will extend the life of the Reverse Osmosis Membrane. It is best to use a special 1¼" diameter cutter designed for porcelain. A carbide tipped masonry bit is a second choice.

B. Reverse Osmosis Feed Water Ball Valve Installation 3. With the Reverse Osmosis Feed Water Ball Valve closed, open the Reverse Osmosis sink faucet and the water supply and allow the water to run for a few minutes to flush any debris caused by the installation. Decide on location. Do NOT connect Reverse Osmosis to a hot water feed line. Water over 100ºF may cause permanent damage to the Reverse Osmosis Membrane. (Refer to Fig. 3 page 8.) 1.
3. Locate the 3/8" Black Drain Tubing connected to the Reverse Osmosis System. Route to the Reverse Osmosis tubing to the Drain Clamp and trim to length. C. Reverse Osmosis Drain Clamp Installation Choose the Reverse Osmosis drain outlet location. The following are instructions for discharging in the sink drain pipe. (Refer to Fig. 1, page 3) CAUTION: The lowest point of the line should be the point of connection to the Reverse Osmosis Drain Clamp.
• Slowly open the Reverse Osmosis Feed Water Ball Valve (turning counter clockwise). D. Position the Reverse Osmosis Holding Tank & Make the Final Hose Connections 1. Check the Reverse Osmosis tank precharge pressure. Make sure it is between 5 to 7 psig. • As soon as the water begins to come out of the Reverse Osmosis Dispensing Faucet, close the Faucet. 2. Pull the cap/plug off the top of the Reverse Osmosis tank where the Reverse Osmosis Tank Shut-Off should go. (Refer to Fig.
1. Close the Reverse Osmosis Feed Water Ball Valve by turning fully clockwise and open the Re4verse Osmosis Dispensing Faucet by lifting the handle. Allow the REverse Osmosis Holding Tank to empty. REVERSE OSMOSIS OPERATION & MAINTENANCE A. Reverse Osmosis Normal Operation 1. Reverse Osmosis systems produce drinking water at relatively slow rates. Normal operation is to let the Reverse Osmosis Holding Tank fill with water and then draw water as is needed.
3 ml) into the Reverse Osmosis tubing and reconnect it to the Tee. 5. Slowly open the Reverse Osmosis Feed Water Ball Valve. NOTE: Now is the convenient time to change the In-Line Reverse Osmosis Activated Carbon Post Filter. 6. When water begins dripping out of the Reverse Osmosis Faucet, in the following order, close the Reverse Osmosis Faucet and open the Reverse Osmosis Holding Tank Valve.

REVERSE OSMOSIS TROUBLE SHOOTING GUIDE Problem Low quantity of Reverse Osmosis Product Water from Holding Tank Possible Cause Reverse Osmosis Feed Water Ball Valve is plugged or closed. Clogged Sediment Pre-filter or Activated Carbon Pre-filter. Low water pressure. Reverse Osmosis. Membrane is fouled. Plugged In-Line Activated Carbon Post Filter. Air pre-charge pressure in Holding Tank is too high.
Problem High Total Dissolved Solids (TDS) in the Product Water (continued) Possible Cause The Product Water and Drain Water lines are reversed. No drain flow, Reverse Osmosis Drain Restrictor is clogged. The Reverse Osmosis ASO Valve is not closing. New In-Line or Activated Carbon Pre-filter not rinsed completely. The Reverse Osmosis Feed Water TDS has increased. Tastes and odors in the Reverse Osmosis Product Water The In-Line or Activated Carbon Pre-filter is exhausted.
