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 nut driver and ¹⁄₂" open-end or two adjustable wrenches drill bit ■ Cordless drill NOTE: Your refrigerator dealer has a kit available with a ¹⁄₄" (6.35 mm) saddle-type shutoff valve, a union, and copper tubing. Before purchasing, make sure a saddle-type valve complies with your local plumbing codes. Do not use a piercing-type or 4.76 mm) saddle valve which reduces water flow and clogs more easily. IMPORTANT: ■ All installations must meet local plumbing code requirements. ■ Use copper tubing and check for leaks. Install copper tubing only in areas where the household temperatures will remain above freezing. Water Pressure A cold water supply with water pressure of between 30 and 120 psi (207 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. ■ If your refrigerator has a water dispenser: After installation is complete, use the water dispenser to check the water pressure. ■ With the water filter removed, dispense 1 cup (237 mL) of water. If 1 cup of water is dispensed in 8 seconds or less, the water pressure to the refrigerator meets the minimum requirement. ■ If it takes longer than 8 seconds to dispense 1 cup of water, the water pressure to the refrigerator is lower than recommended. See "Problem Solver" for suggestions. 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 30 and 120 psi (207 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" in the User Instructions, User Guide, or Use & Care Guide. If you have questions about your water pressure, call a licensed, qualified plumber. INSTALLATION INSTRUCTIONS Unpack the Refrigerator WARNING Excessive Weight Hazard Use two or more people to move and install refrigerator. Failure to do so can result in back or other injury. Remove the Packaging Dispose of/recycle all packaging materials. Do not use sharp instruments, rubbing alcohol, flammable fluids, or abrasive cleaners to remove tape or glue. These products can damage the surface of your refrigerator. IMPORTANT: ■ Use ¹⁄₂" socket wrench to remove skids (socket extension is recommended). ■ All four leveling legs must contact the floor to support and stabilize the full weight of the refrigerator. When Moving Your Refrigerator: Your refrigerator is heavy. When moving the refrigerator for cleaning or service, be sure to cover the floor with cardboard or hardboard to avoid floor damage. Always pull the refrigerator straight out when moving it. Do not wiggle or "walk" the refrigerator when trying to move it, as floor damage could occur. Clean Before Using After you remove all of the package materials, clean the inside of your refrigerator before using it. See the cleaning instructions. Important information to know about glass shelves and covers: Do not clean glass shelves or covers with warm water when they are cold. Shelves and covers may break if exposed to sudden temperature changes or impact, such as bumping. Tempered glass is designed to shatter into many small, pebble-size pieces. This is normal. Glass shelves and covers are heavy. Use both hands when removing them to avoid dropping. 6
