ENGLISH Water Pressure You will need a cold water supply. Water Pressure • Models with water filter: - 20 - 120 psi (138 - 827 kPa) • 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. • 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. If you are using a PEX water line kit, • 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 fitting with a tube cutter and use a compression fitting. NOTE • The hookup line cannot be white, plastic tubing. Licensed plumbers must use only copper tubing (NDA tubing #49595 or #49599) or Cross Link Polyethylene (PEX) tubing. • Be sure there is sufficient extra tubing (about 8 ft. coiled into three turns of about 10 in. diameter) to allow the refrigerator to move out from the wall after installation. Connecting Water Line to Refrigerator 1 Connect the tubing to the shutoff valve. • Place the compression nut and ferrule (sleeve) onto the end of the copper tubing and connect it to the shutoff valve. If you are using PEX, the tubing may already have the required fittings at either end. Make sure the tubing is fully inserted into the valve. Tighten the compression nut securely. a Packing Nut b Shutoff Valve c Compression Nut d Ferrule (sleeve)
