BEFORE YOU BEGIN
This water line installation is not warranted by the
refrigerator or icemaker manufacturer. Follow these
instructions carefully to minimize the risk of expensive
water damage.
Water hammer (water banging in the pipes) 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 the icemaker power switch is in the O
(off) position.
Do not install the icemaker tubing in areas where
temperatures fall below freezing.
When using any electrical device (such as a power
drill) during installation, be sure the device is double-
insulated or grounded in a manner to prevent the hazard
of electric shock, or is battery-powered.
All installations must be in accordance with local plumbing
code requirements.
NOTE: Wear eye protection.
WHAT YOU WILL NEED
Copper Tubing, 1/4” outer
diameter to connect the refrigerator
to the water supply. Be sure both
ends of the tubing are cut square.
To determine how much tubing you need: measure
the distance from the water valve on the back of the
refrigerator to the water supply pipe. Then add 8 feet
(2.4 m). Be sure there is sufficient extra tubing (about 8 feet
[2.4 m] coiled into 3 turns of about 10” [25 cm] diameter) to
allow the refrigerator to move out from the wall after
installation.
Be sure that the kit you select allows at least 8 feet
(2.4 m) as described above.
A cold water supply .The water pressure must be
between 20 and 120 PSI or 0.137 and 0.82 MPa on
120 PSI or 0.275 and 0.82 MPa on models with a
water filter.

wrench.
Straight- and Phillips-
blade screwdriver
Two 1/4” outer diameter
compression nuts and
2 ferrules (sleeves) to
connect the copper tubing to
the shut off valve and the
refrigerator water valve.
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.
Shut off valve to connect to
the cold water line. The
Shut off 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.
INSTALLATION INSTRUCTIONS
Install the shut off valve on the nearest frequently used
drinking water line.
1. SHUT OFF THE MAIN WATER SUPPLY
Turn on the nearest faucet to relieve the pressure on
the line.
CONNECTING THE WATERLINE
NOTE: Water line installation is needed when the
Automatic Ice Maker and/or Water Dispenser features
are available on your product.

Ÿ If a reverse osmosis water filtration system is connected
to your cold water supply, This water line installation is not
warranted by the refrigerator or icemaker manufacturer.
Follow next instructions carefully to minimize the risk of
expensive water damage.
Ÿ If a reverse osmosis water filtration system is connected
to your cold water supply, the water pressure to the reverse
osmosis system needs to be a minimum of 40 to 60 PSI or
0.27 MPa to 0.41MPa (2.8 kg·f/cm² ~ 4.2 kg·f/cm², less than
2 ~ 3 seconds to fill a cup of 7 oz capacity [0.2 liters]).
If the water pressure from the reverse osmosis system is less
than 21 PSI or 0.14 MPa (1.5 kg·f/cm², more than 4 seconds
to fill a cup of 7 oz capacity [0.2 liters]).
Ÿ Check to see whether the sediment filter in the reverse
osmosis system is blocked. Replace the filter if necessary.
Ÿ Allow the storage tank on the reverse osmosis system to
refill after heavy usage.
Ÿ If the issue about water pressure from reverse osmosis
remains, call a licensed, qualified plumber.
