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
ft. coiled into three turns of about 10 in.
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.
