CONNECTING THE WATER LINES IMPORTANT: Before connecting the tubing to the water line, unplug the refrigerator or disconnect the power. • Turn off the main water supply and open the nearest faucet to relieve pressure in the line. Opening an outside faucet may help drain water from the line in the house. • Find a 1/2-in. vertical COLD water pipe near the refrigerator. NOTE: A horizontal pipe will work, but the following precaution must be taken: drill on the top of the pipe, not the bottom. This will help keep water away from the drill and also keep normal sediment from collecting in the valve. • To determine the length of copper tubing you will need, measure from the connection on the lower left rear of the refrigerator to the water pipe. Add 7 ft. (2.1 m) to allow for moving the refrigerator for cleaning. Use 1/4-in. O.D. (outside diameter) copper tubing. Be sure both ends of the copper tubing are cut square. • Using a drill, drill a 1/4-in. hole in the cold water pipe you have selected. • Fasten the shutoff valve to the cold water pipe with the pipe clamp. Be sure the outlet end is solidly in the 1/4-in. drilled hole in the water pipe and the washer is under the pipe clamp. Tighten the packing nut. Tighten the pipe clamp screws carefully and evenly so the washer makes a watertight seal. Do not overtighten or you may crush the copper tubing, especially if soft (coiled) copper tubing is used. Now you are ready to connect the copper tubing. • Slip the compression sleeve and the compression nut onto the copper tubing as shown. Insert the end of the tubing into the outlet end squarely as far as it will go. Screw the compression nut onto the outlet end with a wrench. A flare nut wrench works best, but an open-end wrench will suffice. Do not overtighten. • Place the free end of the tubing into a container or sink, and turn on the main water supply. Flush out the tubing until the water is clear. Turn off the shutoff valve on the water pipe. Coil the copper tubing as shown below. Cold Water Pipe Packing Nut Pipe Clamp Coil of Polyethelyne or Copper Tubing Shutoff Valve Compression Sleeve Compression Nut IMPORTANT: Before connecting the tubing to the refrigerator, be sure the refrigerator power cord is not plugged into the wall outlet. NOTE: If your refrigerator is equipped with an internal water filter, an external in-line water filter should not be used. Tubing Clamp 1/4" Tubing • Place the compression nut and ferrule (sleeve) onto the end of the tubing as shown. • Insert the end of the copper tubing into the connection as far as possible. While holding the tubing, tighten the fitting. IMPORTANT: Tighten any connections that leak. Open the water at the shutoff valve. • Plug in the refrigerator. • Arrange the coil of copper tubing behind the refrigerator so it does not vibrate against the back of the refrigerator or against the wall. 1/4" Compression Nut • Check for leaks. • Before connecting the water line to house, purge the house line for 2 minute. Ferrule (Sleeve) Water valve NOTE: It may take a few seconds for water to begin to flow as the internal tank fills and air clears from the lines. • Push the refrigerator back to the wall. Refrigerator Connection • Remove the plastic flexible cap from the water valve. • Set the icemaker switch to the ON position. NOTE: The icemaker will not begin to operate until it reaches its operating temperature of 15°F (-9°C). It will then begin operation automatically. NOTE: Throw away the first few batches of ice (about 20 pieces). 18
