4. 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 feet (2.1 m) to allow for moving refrigerator for cleaning.
Use 1 / 4 -inch O.D. (outside diameter) copper tubing. Be sure both ends of
copper tubing are cut square.
5. Using a drill, drill a i/ 4 -inch hole in the cold water pipe you have selected.
6. Fasten shut-off valve to cold water pipe with pipe clamp.
Be sure the outlet end is solidly in the I/ 4 " 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.
7. 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 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.
8. 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.
