INSTALLATION 15 ENGLISH Connecting the Water Line Before You Begin This water line installation is not covered by the refrigerator warranty. 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 can lead to water leakage or flooding. Call a qualified plumber to correct water hammer before installing the water supply line to the refrigerator. CAUTION To prevent burns and product damage, only connect the refrigerator water line to a cold water supply. If you use your refrigerator before connecting the water line, make sure the icemaker power switch is in the OFF (O) position. CAUTION Do not install the icemaker tubing in areas where temperatures fall below freezing. Water Pressure You will need a cold water supply. The water pressure must be between 20 and 120 psi on models without a water filter and between 40 and 120 psi on models with a water filter. If the water pressure does not reach the minimum requires pressure, a separate booster pump may be required for normal automatic icemaker and cool water dispensing operation. If a reverse osmosis water filtration system is connected to your cold water supply, this water line installation is not covered by the refrigerator warranty. Follow the following 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 (2.8 kgf/cm2 ~ 4.2 kgf/cm2, or less than 2.0~3.0 sec. to fill a cup of 7 oz capacity). CAUTION Wear eye protection during installation to prevent injury. If the water pressure from the reverse osmosis system is less than 21 psi or 1.5 kgf/cm2 (takes more than 4.0 sec to fill a cup of 7 oz 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 issue concerning water pressure from reverse osmosis remains, call a licensed, qualified plumber.  All installations must be in accordance with local plumbing code requirements. What You Will Need  Copper 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. Keep the total length of the feed water pipe tube within 26 ft (8 m). Be careful to avoid getting a kink in the tube. If the tube is longer than 26 ft (8 m), it may cause the water feed to malfunction.  Power drill.  ½ in. or adjustable wrench.  Flat blade and Phillips head 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.
