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 Controls." Water Supply Requirements Gather the required tools and parts before starting installation. Read and follow the instructions provided with any tools listed here. TOOLS NEEDED: ■ Flat-blade screwdriver and ¹⁄₂" Open-end or two adjustable wrenches Nut driver Drill bit ■ Cordless drill IMPORTANT: ■ All installations must meet local plumbing code requirements. ■ Do not use a piercing-type or 4.76 mm) saddle valve which reduces water flow and clogs more easily. ■ Use copper tubing and check for leaks. Install copper tubing only in areas where the household temperatures will remain above freezing. ■ For models with water filters, the disposable water filter should be replaced at least every 6 months. Water Pressure 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. 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). If the water pressure to the reverse osmosis system is less than 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 usage. ■ 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 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. ■ If you turn on the refrigerator before the water line is connected, turn off the ice maker to avoid excessive noise or damage to the water valve. Connect to Water Line 1. Unplug refrigerator or disconnect power. 2. Turn off main water supply. Turn on nearest faucet long enough to clear line of water. 3. Find a ¹⁄₂" to 1¹⁄₄" (12.7 mm to 31.8 mm) vertical cold water pipe near the refrigerator. IMPORTANT: ■ Make sure it is a cold water pipe. ■ Horizontal pipe will work, but the following procedure must be followed: Drill on the top side of the pipe, not the bottom. This will help keep water away from the drill. This also keeps normal sediment from collecting in the valve. 4. Determine the length of copper tubing you need. Measure from the connection on the lower right rear of the refrigerator to the water pipe. Add 7 ft (2.1 m) to allow for cleaning. Use ¹⁄₄" (6.35 mm) O.D. (outside diameter) copper tubing. Be sure both ends of copper tubing are cut square. 4
