Connecting the Water Line

Before You Begin

This water line installation is not covered by the
refrigerator warranty. 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 can lead to water leakage or flooding.
Call a qualified plumber to correct water hammer
before installing the water supply line to the
refrigerator.
CAUTION
To prevent burns and product damange,
only connect the refrigerator water line to
a cold water supply.
If you use your refrigerator before connecting
the water line, make sure the icemaker power
button is turned off.
CAUTION
Do not install the icemaker tubing in
areas where temperatures fall below
freezing.

Water Pressure

The water pressure must be between 20 and
120 psi. If the refrigerator is installed in an area
with low water pressure (below 20 psi), you can
install a booster pump to compensate for the low
pressure.
If a reverse osmosis water filtration system is
connected to your cold water supply, this water
line installation is not covered by the refrigerator
warranty. Follow the instructions carefully to
minimize the risk of expensive water damage.
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 (276-414 kPa or
2.8-4.2 kgf/cm², less than 2.0-3.0 sec. to fill a cup
of 7 oz or 198 cc capacity).
CAUTION
Wear eye protection during installation
to prevent injury.
If the water pressure from the reverse osmosis
system is less than 20 psi or 138 kPa or 1.4 kgf/
cm² (takes more than 4.0 sec to fill a cup of 7 oz
or 198 cc capacity):
Check to see if the sediment filter in
y
the reverse osmosis system is blocked.
Replace the filter if necessary.
Allow the storage tank on the reverse
y
osmosis system to refill after heavy
usage.
If the issue concerning water pressure
y
from reverse osmosis remains, call a
licensed, qualified plumber.
All installations must be in accordance
y
with local plumbing code requirements.

What You Will Need

¼ in. outer diameter, to
y Copper Tubing,
connect the refrigerator to the water
supply. Be sure both ends of the tubing
are cut square.
To determine how
y
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 in. [25 cm] diameter) to allow the
refrigerator to move out from the wall
after installation.
y Power drill.
y ½ in. or adjustable
wrench.
y Flat blade and Phillips
head screwdrivers.
y 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.
