CONNECTING THE WATER LINE 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 th.e 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 local must be in accordance with plumbing code requirements. NOTE: Wear eye protection. WHAT YOU WILL NEED Copper Tubing, 1/4" (6.35 mm) 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 0.137 and 0.82 MPa (20 and 120 PSI or 1.4 bar and 8.2 bar) on models without a water filter and between 0.275 and 0.82 MPa (40 and 120 PSI or 2.8 bar and 8.2 bar) on models with a water filter. Power drill. ½" (12.7 mm) or Adjustable Wrench. Flat head-and Phillipsscrewdrivers. • 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 instruction carefully to minimize the risk of expensive water damage. • Two 1/4" (6.35 mm) outer diameter compression nuts and 2 Ferrules (sleeves) to connect the copper tubing to the shutoff valve and the refrigerator water valve. • 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 (2.8 kg•f/cm2 ~ 4.2 kg•f/cm2, less than 2~3 sec to fill a cup of 7 oz capacity). If the water pressure from the reverse osmosis system is less than 21 PSI (1.5 kg•f/cm2, more than 4 sec to fill a cup of 7 oz capacity). • 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. • 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 (3.96 mm) 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. 20
