NOTE: This refrigerator is intended for use in a location where the temperature ranges from a minimum of 55°F (13°C) to a maximum of 110°F (43°C). The preferred room temperature range for optimum performance, which reduces electricity usage and provides superior cooling, is between 60°F (15°C) and 90°F (32°C). It is recommended that you do not install the refrigerator near a heat source, such as an oven or radiator. ¹⁄₂" (1.25 cm) 3³⁄₄" (9.5 cm) Electrical Requirements WARNING 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. NOTE: Before performing any type of installation, cleaning, or removing a light bulb, turn OFF Cooling, and 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 Control(s)." 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. ■ 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: ■ 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 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 and ¹⁄₂" open-end wrenches or two adjustable wrenches nut driver NOTE: Do not use a piercing-type or 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 shutoff valve or the equivalent, served by a ¹⁄₂" household supply line. 12
