Reverse Osmosis Water Supply IMPORTANT: The pressure of the water supply coming out of a reverse osmosis system going to the water inlet valve of the refrigerator needs to be between 35 psi and 120 psi (241 kPa and 827 kPa). If a reverse osmosis water filtration system is connected to your cold water supply, the water pressure to the reverse osmosis system needs to be a minimum of 40 psi to 60 psi (276 kPa to 414 kPa). ■ Check to see whether the sediment filter in the reverse osmosis system is blocked. Replace the filter if necessary. ■ Allow the storage tank on the reverse osmosis system to refill after heavy use. The tank capacity could be too small to keep up with the requirements of the refrigerator. NOTE: Faucet mounted reverse osmosis systems are not recommended. ■ If your refrigerator has a water filter, it may further reduce the water pressure when used in conjunction with a reverse osmosis system. Remove the water filter. See "Water Filtration System." If you have questions about your water pressure, call a licensed, qualified plumber. Connect the Water Supply Read all directions before you begin. IMPORTANT: ■ Connect to potable water supply only. A B C D A. Sleeve C. Copper tubing (to refrigerator) B. Nut D. Household supply line (1/2" minimum) 4. Now you are ready to connect the copper tubing to the shutoff valve. Use 1/4" (6.35 mm) OD soft copper tubing to connect the shutoff valve and the refrigerator. ■ Ensure that you have the proper length needed for the job. Be sure both ends of the copper tubing are cut square. ■ Slip compression sleeve and compression nut onto copper tubing as shown. Insert end of tubing into outlet end squarely as far as it will go. Screw compression nut onto outlet end with adjustable wrench. Do not overtighten. Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts. ■ Plumbing shall be installed in accordance with the International Plumbing Code and any local codes and ordinances. ■ The gray water tubing on the back of the refrigerator (which is used to connect to the household water line) is a PEX (cross-linked polyethylene) tube. Copper and PEX tubing connections from the household water line to the refrigerator are acceptable, and will help avoid off-taste or odor in your ice or water. Check for leaks. If PEX tubing is used instead of copper, we recommend the following Whirlpool Part Numbers: W10505928RP (7 ft [2.14 m] jacketed PEX), 8212547RP (5 ft [1.52 m] PEX), or W10267701RP (25 ft [7.62 m] PEX). ■ Install tubing only in areas where temperatures will remain above freezing. TOOLS NEEDED: Gather the required tools and parts before starting installation. ■ Flat-blade screwdriver ■ 7/16" and 1/2" open-end wrenches or two adjustable wrenches ■ 1/4" nut driver NOTE: Do not use a piercing-type or 3/16" (4.76 mm) saddle valve which reduces water flow and clogs easier. Connect to Water Line IMPORTANT: If you turn the refrigerator on before the water is connected, turn the ice maker OFF. 1. Unplug refrigerator or disconnect power. 2. Turn OFF main water supply. Turn ON nearest faucet long enough to clear line of water. 3. Use a quarter-turn shutoff valve or the equivalent, served by a 1/2" household supply line. NOTE: To allow sufficient water flow to the refrigerator, a minimum 1/2" size household supply line is recommended. AB C A. Compression sleeve C. Copper tubing B. Compression nut 5. Place the free end of the tubing into a container or sink, and turn on main water supply to flush out tubing until water is clear. Turn off shutoff valve on the water pipe. NOTE: Always drain the water line before making the final connection to the inlet of the water valve, to avoid possible water valve malfunction. 6. Bend the copper tubing to meet the water line inlet, which is located on the back of the refrigerator cabinet as shown. Leave a coil of copper tubing to allow the refrigerator to be pulled out of the cabinet or away from the wall for service. Connect to Refrigerator Follow the connection instructions specific to your model. Style 1 1. Remove plastic cap from water valve inlet port. Attach the copper tube to the valve inlet using a compression nut and sleeve as shown. Tighten the compression nut. Do not overtighten. Confirm copper tubing is secure by pulling on copper tubing. 2. Create a service loop with the copper tubing. Avoid kinks when coiling the copper tubing. Secure copper tubing to refrigerator cabinet with a "P" clamp. A B C D A. Copper tubing B. "P" clamp C.
