Step 3: Install RO Filter Assembly INSTALL REVERSE OSMOSIS FILTER ASSEMBLY Hanger Washer (2) The Reverse Osmosis Filter Assembly is mounted on hanger washers. See Fig 11. 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. Screw (2) Complete the following steps to install your Reverse Osmosis Filter Assembly: 1. Remove the cover. 2.
Step 4 - Install Storage Tank INSTALL STORAGE TANK Tubing Connector 1. Apply thread sealing tape to the threads on the nipple at the top of the tank. See Fig 12. 2. Locate the tubing connector. Hand tighten the tubing connector onto the tank nipple being careful not to cross thread. See Fig 12. 3. Tighten the adapter 1/4 turn with a wrench. See Fig 12. 4. Set the tubing insert and nut aside for now. See Fig 12. Do not connect the tube at this time. This will occur later in the assembly. 5.
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 1-3/8” 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 INSTALL REVERSE OSMOSIS FAUCET 1. Locate and organize your RO faucet install parts. Refer to Fig. 14. 2. Mount faucet base to sink hole until the faucet base is square against the sink surface. The rubber gasket should be between the sink surface and the faucet base. 3. Tighten the toggle bolts until the base is firmly mounted to the sink surface. Do not overtighten. 4. Locate the faucet base. (The black and blue tubes are already connected to the faucet.
Step 6 - Connect Tubes Push In Fitting HOW TO CUT AND CONNECT THE TUBES Tube 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 Fig. 17. 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.
Step 6 - Connect Tubes 1/4" RED sink p-trap E LU "B HOT COLD 1/4" GREEN saddle valve 3/8 drain adaptor 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 3/8" black tubing 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 Fig. 23. 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 Note: Complete the sanitizing procedures on the preceding page before pressure testing. Kitchen faucet Reverse Osmosis Faucet To pressure test the system, complete the following steps. 1. Open the water supply valve to the Reverse Osmosis System. See Fig. 24. 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 Fig. 24. 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.
How Your RO Water System Works PRODUCT WATER FAUCET air gap BL AC K 6 PRODUCT WATER gravity drain WASTE WATER AUTOMATIC SHUTOFF WATER IN drain flow control check valve 8 GREEN BLUE PRODUCT WATER STORAGE POSTFILTER PREFILTER 7 5 RED 1 RO MEMBRANE 3 YELLOW 4 2 Reverse Osmosis Water Flow Schematic Water Flow Description 1. 2. 3. 4. 5. 6. 7. 8. Water enters prefilter. Sand, silt and other sediments are removed. Chlorine is also removed. See Fig. 25.
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 Fig. 26. 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 Fig. 27. 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. If the flow control assembly requires service, review the exploded view in Fig. 27.
