20 INSTALLATION Assembling the Hinge Cover Position the hinge cover in its place. Insert and tighten the cover screws. Connecting the Water Line Before Beginning This water line installation is not covered by the refrigerator warranty. Follow these instructions carefully to minimize the risk of expensive water damage. If necessary, call a qualified plumber to correct water hammer before installing the water supply line to the refrigerator. Water banging in the pipes (water hammer) in residential plumbing can cause damage to refrigerator parts and lead to water leakage or flooding. • Turn the icemaker OFF if the refrigerator will be used before the water line is connected. • Do not install the icemaker tubing in areas where the ambient temperatures fall below freezing. WARNING • Connect to potable water supply only. CAUTION • To prevent burns and product damage, only connect the refrigerator water line to a cold water supply. • Wear eye protection during installation to prevent injury. • Where reverse osmosis water filtration system is connected to a cold water supply: - 40 - 60 psi minimum to reverse osmosis system (2.8 kgf/cm2 - 4.2 kgf/cm2, or less than 2 - 3 seconds to fill a cup of 7 oz capacity) If the water pressure from the reverse osmosis system is less than 20 psi or 138 kPa or 1.4 kgf/cm2 (takes more than 4 seconds to fill a cup of 7 oz or 198 cc capacity): • Check to see if 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 water pressure remains low, call a licensed, qualified plumber. • All installations must be in accordance with local plumbing code requirements. Supplies Needed • Copper or PEX Tubing, ¼ in. 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 in. [25 cm] diameter) to allow the refrigerator to move out from the wall after installation. • Power drill. • ½ in. or adjustable wrench. • Flat-blade and Phillips screwdrivers. • Two ¼ in. outer diameter compression nuts and 2 ferrules (sleeves) to connect the copper tubing to the shutoff valve and the refrigerator water valve. Water Pressure You will need a cold water supply. Water Pressure • Models with water filter: - 20 - 120 psi (138 - 827 kPa) • If your existing copper water line has a flared fitting at the end, purchase an adapter (available at plumbing supply stores) to connect the water line to the refrigerator OR cut off the flared
