GE IM4A Owner's Manual And Installation Instructions page 39

WHAT YOU WILL NEED
• Two 1/4 " outer diameter compression nuts and
2 ferrules (sleeves)---to connect the copper tubing
to the shutoff valve and the refrigerator water valve.
OR
• If you are using a GE SmartConnect
Tubing kit, the necessary fittings are preassembled
to the tubing.
• If your existing copper water line has a flared
fitting at the end, you will need an adapter
(available at plumbing supply stores) to connect
the water line to the refrigerator OR you can cut
off the flared fitting with a tube cutter and then
use a compression fitting. Do not cut formed end
from GE SmartConnect
• 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" 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.
Install the shutoff valve on the nearest frequently used
drinking water line.

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.
DRILL THE HOLE FOR THE VALVE
3
Drill a 1/4" hole in the water pipe (even if using
a self-piercing 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 SHUTOFF VALVE
Fasten the shutoff valve to the cold water pipe with
the pipe clamp.
