Electrical Requirements WARNING ■■ 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" section. If you have questions about your water pressure, call a licensed, qualified plumber. Connect the Water Supply Electrical Shock Hazard Plug into a grounded 3 prong outlet. Do not remove ground prong. Do not use an adapter. Do not use an extension cord. Failure to follow these instructions can result in death, fire, or electrical shock. Before you move your refrigerator into its final location, it is important to make sure you have the proper electrical connection. Recommended Grounding Method A 115-volt, 60 Hz, AC-only 15- or 20-amp fused, grounded electrical supply is required. It is recommended that a separate circuit serving only your refrigerator and approved accessories be provided. Use an outlet that cannot be turned off by a switch. Do not use an extension cord. IMPORTANT: If this product is connected to a GFCI (Ground Fault Circuit Interrupter) protected outlet, nuisance tripping of the power supply may occur, resulting in loss of cooling. Food quality and flavor may be affected. If nuisance tripping has occurred, and if the condition of the food appears poor, dispose of it. NOTE: Before performing any type of installation or cleaning, turn off cooling, then disconnect the refrigerator from the electrical source. When you have finished, reconnect the refrigerator to the electrical source and turn on cooling. See "Using the Controls" section. Water Supply Requirements A cold water supply with water pressure between 35 and 120 psi (241 and 827 kPa) is required to operate the water dispenser and ice maker. If you have questions about your water pressure, call a licensed, qualified plumber. NOTE: If the water pressure is less than what is required, the flow of water from the water dispenser could decrease or ice cubes could be hollow or irregular shaped. 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 and 120 psi (241 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 to 60 psi (276 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. Read all directions before you begin. IMPORTANT: ■■ 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 off-taste 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 ■■ ¼" 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 off the ice maker. 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 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 C. Copper tubing (to refrigerator) B. Nut D.
