What Your Reverse Osmosis System Will Do Your Reverse Osmosis (RO) Drinking Water System is a water treatment unit. It uses household water pressure to reverse a natural physical process called osmosis. Water, under pressure, is forced through a semi-permeable membrane where minerals and impurities are filtered out. Clean drinking water goes to the faucet or storage, while minerals and impurities are sent to the drain with RO waste water.
Plan Your Installation Typical Under Sink Installation All install parts included in package.
Overview and Site Preparation OVERVIEW There are seven easy steps to installing your Drinking Water system. They are as follows: STEP 1 - Install Cold Water Supply fitting STEP 2 - Install Drain Adapter STEP 3 - Install Reverse Osmosis Assembly STEP 4 - Install Storage Tank STEP 5 - Install Reverse Osmosis Faucet STEP 6 - Connect Tubing STEP 7 - Sanitize, Pressure Test, Purge System These steps are explained in detail over the next few pages.
Step 1 - Install Supply Water Fitting CHOOSE TYPE OF WATER FITTING TO INSTALL Locate the cold water line in the sink cabinet. It is recommended, but not required, that the cold water line be soft water. You can use the saddle valve provided with your unit to tap into the cold water line. See Fig. 5. Or you can purchase standard pipe fittings locally such as a compression fitting. The fitting must provide a leak-tight connection to the Reverse Osmosis 1/4" tube.
Step 2 - Install RO Drain Under Sink INTRODUCTION Under The Sink Installation A suitable drain point is needed for the reject water from the Reverse Osmosis Filter. You have two options to choose from: • Install the Drain Adapter included with your unit See Figures 6, 7 & 8. This is used in under the sink installations. The drain adapter kit is installed onto your sink drain pipe above the P-trap. See Figure 6.

Step 3 - Install RO Filter Assembly INSTALL REVERSE OSMOSIS FILTER ASSEMBLY Hanger Washer (2) The Reverse Osmosis Filter Assembly is mounted on hanger washers. The hanger washers allow you to lift the filter assembly from the washers without any hardware removal. When planning your installation, you need to leave room for changing filters. See Figure 11. Screw (2) 9'' Complete the following steps to install your Reverse Osmosis Filter Assembly: 1. Remove the cover. 2.
Step 5 - Install RO Faucet SELECT LOCATION OF REVERSE OSMOSIS FAUCET MOUNTING HOLE You will need to select the location of the Reverse Osmosis Faucet. You have three options to choose from: • Use the existing sink top hole for the spray hose or soap dispenser (Must be 1-1/4” in diameter) • Drill a new hole in the sink • Drill a new hole in the countertop next to the sink 1. Determine where you are going to install your Reverse Osmosis Faucet. 2.
Step 5 - Install RO Faucet 5. Locate the 1/4" red tubing. One end is connected to the RO Filter assembly. See Figure 21. Locate the loose end. A. Route red tube through countertop to faucet. B. Cut the loose end of the red tube square and to length. See Figure 21. NOTE: Tubing lengths should allow for the removal of the assembly from the hanger washers for servicing. If tubing lengths are shortened for neater appearance, it may be necessary to keep the assembly on the hanger washers for service. C.
Step 6 - Connect Tubes HOW TO CUT AND CONNECT THE TUBES Your Reverse Osmosis Water System includes push-in fittings for quick tubing connection. Review the following instructions before connecting the tubes in the next step. Cut tubes to length 1. Use a sharp cutter or knife to cut the end of tubing. Always cut the tubing square. See Figure 16. 2. Inspect the end (about 1") of the tubing to be sure there are no nicks, scratches or other rough spots. If needed, cut the tubing again. See Figure 16.
Step 6 - Connect Tubes NOTE: Tubing lengths should allow for the removal of the assembly from the hanger washers for servicing. If tubing lengths are shortened for neater appearance, it may be necessary to keep the assembly on the hanger washers for service. NOTE: Codes in the state of Massachusetts require installation by a licensed plumber and do not permit the use of saddle valves.
Step 7 - Sanitize, Test and Purge System SANITIZE THE SYSTEM Sanitizing is recommended immediately after installation of the Reverse Osmosis system. It’s also recommended after servicing inner parts. It is important that the person installing or servicing the system have clean hands while handling inner parts of the system. Complete the following steps to sanitize the system. See Figure 22. 1. Turn off the water supply to the Reverse Osmosis system. 2. Open the Reverse Osmosis faucet. 3.
Step 7 - Sanitize, Test and Purge System PRESSURE TEST THE SYSTEM Reverse Osmosis Faucet NOTE: Complete the sanitizing procedures on the preceding page before pressure testing. To pressure test the system, complete the following steps. 1. Open the water supply valve to the Reverse Osmosis System. See Figure 23. 2. Open the main water supply valve and several house faucets. This will purge air from the house plumbing and system. Close faucets when water runs smooth. See Figure 23. 3.
How Your RO Water System Works 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 impurities are sent down the drain. The following paragraphs will explain in detail how your Reverse Osmosis Drinking Water System works.

Water enters prefilter. Sand, silt and other sediments are reduced. Chlorine is also reduced. 2.
Maintenance PREFILTER/POSTFILTER MAINTENANCE NOTE: It is recommended to replace the battery, prefilter and postfilter cartridges at least every 6 months of product water use. Replace more often if they begin to plug with sediments. The prefilter and postfilter are replaceable sediment cartridges with activated carbon in its composition. See Figure 25. You must periodically replace the prefilter and postfilter cartridge. This will protect the RO membrane from being destroyed by chlorine.
Maintenance FLOW CONTROL The flow control is vital for proper operation of the Reverse Osmosis membrane cartridge. See Figure 26. The control keeps water flowing through the membrane at the required rate. This is to ensure the system produces the best quality product water. Flow Control Insert Periodically check the flow control assembly to be sure the small hole through it is clean and unrestricted.

Troubleshooting Problem: Chlorine taste and/or odor in the RO product water. Cause: The level of chlorine in your water supply exceeds maximum limits, and has destroyed the Reverse Osmosis membrane. Cause: The prefilter is no longer reducing chlorine from the water supply. Correction: Correction: If the water supply contains more than 2.0 ppm of chlorine, additional filtering of the water supply to the Reverse Osmosis is needed.
Troubleshooting Problem: Water leaking from faucet airgap hole. Cause: Drain side of faucet airgap (3/8” black tub- Correction: ing) plugged, restricted or incorrectly connected to drain point. Inspect and eliminate restriction or plug. Refer to installation instructions for proper drain connection. See page 9. Problem: Faucet LED indicator light does not function after battery change. Cause: Battery dead. Correction: Replace with new battery. See page 21. Cause: Battery installed incorrectly.
