• Two ¼ in. outer diameter compression nuts
and 2 ferrules (sleeves) to connect the copper
tubing to the shutoff valve and the refrigerator
water valve.
• If your existing copper water line has a flared
fitting at the end, purchase an adapter (available
at plumbing supply stores) to connect the water
line to the refrigerator OR cut off the flared
fitting with a tube cutter and then use a
compression fitting.
• Shutoff valve to connect to the cold water line.
The shutoff valve should have a water inlet with
a minimum inside diameter of 5/32 in. at the
point of connection to the COLD WATER LINE.
Saddle-type shutoff valves are included in many
water supply kits. Before purchasing, make sure
a saddle-type valve complies with your local
plumbing codes.
NOTE
• A self-piercing saddle type water valve should
not be used.
Water Line Installation Instructions
Install the shutoff valve on the nearest frequently
used drinking water line.
WARNING
• When using any electrical device (such as a
power drill) during installation, be sure the
device is battery-powered, double-insulated or
grounded in a manner that will prevent the
hazard of electric shock.
1
Shut off the main water supply.
• Turn on the nearest faucet to relieve the
pressure on the line.
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.
NOTE
• 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.
NOTE
• 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.
