Whirlpool WRT138FFD Installation Instructions - Page 17

Connecting the Water Supply Read all directions before you begin. IMPORTANT: Connect to potable water supply only. 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 must be installed in accordance with the International Plumbing Code and any local codes and ordinances. ‡ Copper and PEX tubing connections from the household water line to the refrigerator are acceptable and will help avoid offtaste or odor in your ice or water. Check for leaks. ‡ If PEX tubing is used instead of copper, we recommend the following 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 2 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 have turned the refrigerator on before the water was connected, turn off the ice maker. 1. Unplug refrigerator or disconnect power. 2. Turn off main water supply. Turn on nearest faucet long enough to reduce water pressure in the water line. 3. Use a quarter-turn shut-off 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" (12.7 mm) size household supply line is recommended. A B C D A. Sleeve B. Nut C. Copper tubing (to refrigerator) D. Household supply line (1/2" minimum) 4. Now you are ready to connect the copper tubing to the shut-off valve. Use 1/4" (6.35 mm) O.D. (outside diameter) soft copper tubing to connect the shut-off valve and the refrigerator. 5. Ensure that you have the proper length needed for the job. Be sure both ends of the copper tubing are cut square. 6. 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. A B C A. Compression sleeve C. Copper tubing B. Compression nut 7. 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 shut-off 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. 17
