Chapter 25 Installation and Troubleshooting of Domestic Refrigerators and Freezers 641 Copyright Goodheart-Willcox Co., Inc. 8 Connect the tubing to the valve (usually with a compression fitting). Check how much tubing is required to connect from the valve to the refrigera- tor. The tubing run from the water to the refrigera- tor should include several large loops of tubing that can be placed behind the refrigerator. This extra length of tubing will allow the refrigerator to be moved for cleaning and servicing without requiring the water connection to be cut off or disconnected. Once enough tubing length has been determined, connect the other end of the tubing to the refrigera- tor water line fitting. Turn the water valve stem to turn on the water to the refrigerator-freezer. Check for water leaks. Test the water dispenser if applicable. Check the ice maker to see whether water has filled the ice cube tray and begun its cycle. If everything appears to be working and no leaks are found at any of the connections, gently move the refrigerator to its desired location. Be careful to avoid kinking, buckling, or pinching the tubing at any point.
