Connecting the ice maker to the water supply
Before you begin, please note:
• This water line installation is not warranted by the refrigerator or ice maker
manufacturer.
• Follow these instructions carefully to minimize the risk of water damage.
• Water hammer (water banging in the pipe) in house plumbing can cause
damage to refrigerator parts and lead to water leakage or flooding. Call a
qualified plumber to correct water hammer before installing the water
supply line to the refrigerator.
• To prevent burns and product damage, do not hook up the water line to the
hot water line.
• If you use your refrigerator before connecting the water line, make sure that
the ice maker wire signal arm is in the OFF position.
• Do not install the ice maker tubing in areas where temperature falls below
freezing.
• When using any electrical devices (such as a power drill) during installation,
make sure that the device is double insulated or grounded in a manner to
prevent the hazard of electric shock, or that the device is battery powered.
• All installations must be in accordance with local plumbing code
requirements.
1 Disconnect the refrigerator from the electric wall outlet.
2 Remove the parts in the water line kit that you purchased for this purpose.
3 Connect the end of the water supply line to the household cold water line
behind the refrigerator. Choose a location for the valve that is easy to access.
We recommend that you connect it to the side of a vertical water pipe. If it is
necessary to connect it to a horizontal water pipe, make the connection to the
top or side, rather than at the bottom, to avoiding drawing off any sediment
from the water pipe.
4 Make sure that the household water supply is turned off, then drill a ¼” hole in
the water pipe (even if using a self-piercing valve), using a sharp bit. Remove
any burrs resulting from drilling the hole. Take care not to allow water to drain
into the drill. Failure to drill a ¼” hole may result in reduced ice production or
smaller cubes.
5 Fasten the shutoff valve to the cold water pipe with the pipe clamp, then
tighten the pipe clamp screws until the sealing washer begins to swell. Do not
over-tighten or you may crush the tubing.
6 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.
7 Connect the tubing to the valve by placing the compression nut and ferrules
(sleeves) for copper tubing onto to the end of the tubing and connect it to the
shutoff valve. Make sure that the tubing is fully inserted into the valve.
WARNINGS:
• The ice maker should be installed by an authorized service technician.
• Make sure that the refrigerator is unplugged to eliminate the danger of
electric shock during installation.
Note: Make sure that there is sufficient extra tubing to allow the refrigerator to
move out from the wall after installation.

8 Tighten the compression nut securely. For plastic tubing, insert the molded
end of the tubing into the valve and tighten the compression nut until it is
hand-tight, then tighten one additional turn with a wrench. Over-tightening
may cause leaks.
9 Place the end of the water supply line into a sink or bucket and flush the water
supply line with water until the water runs clear.
10 Unscrew the plastic cap from the water inlet valve and discard it.
11 Slide a brass compression nut, then a ferrule (sleeve), onto the water supply
line.
12 Push the end of the tubing into the water inlet valve as far as it will go or
¼-inch, then slide the ferrule (sleeve) into the valve inlet and finger tighten the
compression nut onto the valve. Tighten another half turn with a wrench. DO
NOT overtighten.
13 Secure the water supply line to the back panel of your refrigerator with a steel
clamp and screw at the location shown on the illustration.
14 Coil the excess water supply line (about 2-½ turns) behind the refrigerator and
arrange the coils so they do not vibrate or wear against any other surface.
15 Turn on the water supply at the shutoff valve and tighten any connections that
leak.
Notes:
• Before making the connection to the refrigerator, be sure the refrigerator
power cord is not plugged into the wall outlet.
• If your refrigerator does not have a water filter, we recommend installing one
if your water supply has sand or particles that could clog the screen of the
refrigerator’s water valve.

17 To turn on the ice maker, lower the wire signal arm.
Tips for using your automatic ice maker
Remember that water quality determines the quality of ice. The ice maker should
not be connected to softened water. If the water softener has problems, chemical
substances can damage the ice maker.
To turn off the ice maker, raise the wire signal arm until it locks in the “up” (off)
position. When the ice storage bin is full, the wire signal arm will hit the ice cubes
and the ice maker will automatically shut down.
If you store ice cubes too long they may produce a peculiar smell. To eliminate the
smell, empty the ice storage bin, wash it out, then replace it. The ice maker will
produce more ice cubes.
Shake the ice storage bin from time to time to ensure that the ice cubes separate
from each other.
Before the refrigerator is connected to the water supply system, or any time the
water supply is turned off, the wire signal arm should be in the “up” or (off)
position.
Maintaining your ice maker
Use mild detergent in warm water to clean the ice storage box, then rinse and dry
it.
Turn off the ice maker when you clean your refrigerator or plan to be away for a
short period.
If you are going away for an extended period, turn off the water supply valve.
Important: It takes approximately 24 hours for the ice maker to begin
producing usable ice. Air in new plumbing lines may cause the ice maker to
cycle two or three times before making a full tray of ice. New plumbing may
cause ice to be discolored or have poor flavor. Discard ice made during the first
24 hours.
