NOTE: Water line installation is needed when the Automatic Icemaker and/or Water Dispenser features are available on your product. BEFORE YOU BEGIN 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. , If a reverse osmosis water filtration system is connected to your cold water supply, This water line installation is not warranted by the refrigerator or icemaker manufacturer. Follow next instructions carefully to minimize the risk of expensive water damage. , 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 or 0.27 MPa to 0.41MPa (2.8 kg.f/cm 2 ~ 4.2 kg.f/cm 2, less than 2 ~ 3 seconds to fill a cup of 7 oz capacity [0.2 liters]). If the water pressure from the reverse osmosis system is less than 21 PSI or 0.14 MPa (1.5 kg.f/cm 2, more than 4 seconds to fill a cup of 7 oz capacity [0.2 liters]). , 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 the issue about water pressure from reverse osmosis remains, call a licensed, qualified plumber. WHAT YOU WILL NEED • Copper Tubing, 1/4" outer diameter to connect the refrigerator 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 PSI or 0.137 and 0.82 MPa on models without a water filter and between 40 and 120 PSI or 0.275 and 0.82 MPa on models with a water filter. ° Power drill. • 1/2" or adjustable wrench. Straight- and PhiHipsbmadescrewdriver Two 1/4" outer diameter compression nuts and 2 ferrules (smeeves) to connect the copper tubing to the shut off 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 cutte rand then use a compression fitting. Shut off vamve to connect to the cold water line. The Shut off 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. mNSTALLATION 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 reaieve the pressure on the Uine. 29
