CONNECTING THE WATERLINE INSTALLATION INSTRUCTIONS (CONTINUED) 2. CHOOSE THE VALVE LOCATION Choose a location for the valve that is easily accessible. It is best to connect into the side of a vertical water pipe. When it is necessary to connect into a horizontal water pipe, make the connection to the top or side, rather than at the bottom, to avoid drawing off any sediment from the water pipe. 3. DRILL THE HOLE FOR THE VALVE Drill a 1/4" hole in the water pipe (even if using a selfpiercing valve) using a sharp bit. Remove any burrs resulting from drilling the hole in the pipe. Take care not to allow water to drain into the drill. Failure to drill a 1/4 hole may result in reduced ice production or smaller cubes. 4. FASTEN THE SHUT OFF VALVE Fasten the shutoff valve to the cold water pipe with the pipe clamp.

Saddle valves are illegal and use is not permitted in Massachusetts. Consult with your licensed plumber. 5. TIGHTEN THE PIPE CLAMP Tighten the clamp screws until the sealing washer begins to swell. NOTE: Do not over tighten or you may crush the tubing. Washer Pipe Clamp Inlet End Clamp Screw 6. ROUTE THE TUBING Route the tubing between the cold water line and the refrigerator. Route the tubing through a hole drilled in the wall or floor (behind the refrigerator or adjacent base cabinet) as close to the wall as possible. NOTE: Be sure there is sufficient extra tubing (about 8 feet or 2.44 m coiled into 3 turns of about 10" or 25.4 cm of diameter) to allow the refrigerator to move out from the wall after installation. 7. CONNECT THE TUBING TO THE VALVE Place the compression nut and ferrule (sleeve) for copper tubing onto the end of the tubing and connect it to the shutoff valve. Make sure the tubing is fully inserted into the valve. Tighten the compression nut securely.

Saddle valves are illegal and use is not permitted in Massachusetts. Consult with your licensed plumber. 8. FLUSH OUT THE TUBING Turn the main water supply on and flush out the tubing until the water is clear. Shut the water off at the water valve after about one quart of water has been flushed through the tubing. 32
