22 INSTALLATION
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 ¼ in. hole in the water pipe using a
sharp bit. Remove any burrs resulting from
drilling the hole in the pipe. Be careful not
to allow water to drain into the drill. Failure
to drill a ¼ in. hole may result in reduced ice
production or smaller cubes.
• The hookup line cannot be white, plastic tubing.
Licensed plumbers must use only copper tubing
(NDA tubing #49595 or #49599) or Cross Link
Polyethylene (PEX) tubing.
4 Fasten the shutoff valve.
• Fasten the shutoff valve to the cold water
pipe with the pipe clamp.
• Commonwealth of Massachusetts Plumbing
Codes 248CMR shall be adhered to. Saddle
valves are illegal and use is not permitted in
Massachusetts. Consult with your licensed
plumber.

5 Tighten the pipe clamp.

washer begins to swell.

the tubing.

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.
• Be sure there is sufficient extra tubing (about 8
ft. coiled into three turns of about 10 in.
