BEFORE YOU BEGIN Unless it is performed by Sears service this water line installation is not warranted by the refrigerator or icemaker manufacturer. Follow these instructions carefully to minimize the risk of expensive water damage. Water hammer (water banging in the pipes) in house plumbing can cause damage to refrigerator parts and lead to water leakage or flooding. Call a qualified plumber to correct water hammer before installing the water supply line to the refrigerator. To prevent burns and product damage, do not hook up the water line to the hot water line. If you use your refrigerator before connecting the water line, make sure the icemaker power switch is in the O (off) position. Do not install the icemaker tubing in areas where temperatures fall below freezing. When using any electrical device (such as a power drill) during installation, be sure the device is doubleinsulated or grounded in a manner to prevent the hazard of electric shock, or is battery-powered. All installations must be in accordance with local plumbing code requirements. NOTE: Wear eye protection (Use security lenses). WHAT YOU WILL NEED • Copper Tubing , 1/4" outer diameter to connect the refrigerator JJ to the water supply. Be sure both ends of the tubing are cut square. To determine how much tubing you need: measure the distance from the water valve on the back of the refrigerator to the water supply pipe. Then add 8 feet (2.4 m). Be sure there is sufficient extra tubing (about 8 feet [2.4 m] coiled into 3 turns of about 10" [25 cm] diameter) to allow the refrigerator to move out from the wall after installation. Be sure that the kit you select allows at least 8 feet (2.4 m) as described above. , A cold water supply. The water pressure must be between 20 and 120 p.s.i. (1.4-8.2 bar) on models without a water filter and between 40 and 120 p.s.i. (2.8-8.2 bar) on models with a water filter. _e,._,,= • Power drill. • 1/2"or adjustable wrench. . Straight- and Phillips-blade screwdriver. Two 1/4" outer diameter compression nuts and 2 ferrules (sleeves) to connect the copper tubing to the shutoff valve and the refrigerator water valve. If your existing copper water line has a flared fitting at the end, you will need an adapter (available at plumbing supply stores) to connect the water line to the refrigerator OR you can cut off the flared fitting with a tube cutter and then use a compression fitting. Shutoff valve to connect to the cold water line. The shutoff valve should have a water inlet with a minimum inside diameter of 5/32" at the point of connection to the COLD WATER LINE. Saddle-type shutoff valves are included in many water supply kits. Before purchasing, make sure a saddle-type valve complies with your local plumbing codes. INSTALLATION INSTRUCTIONS Install the shutoff valve on the nearest frequently used drinking water line. 1. SHUT OFF THE MAIN WATER SUPPLY Turn on the nearest faucet to clear the line of water. 2. CHOOSE THE VALVE LOCATION Choose a location for the valve that is easily accessible. It is best to connect into the side of a vertical water pipe. When it is necessary to connect into a horizontal water pipe, make the connection to the top or side, rather than at the bottom, to avoid drawing off any sediment from the water pipe. 3. DRILL THE HOLE FOR THE VALVE Drill a 1/4" hole in the water pipe (even if using a selfpiercing valve) using a sharp bit. Remove any burrs resulting from drilling the hole in the pipe. Take care not to allow water to drain into the drill. Failure to drill a 1/4" hole may result in reduced ice production or smaller cubes. 21
