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
before installing the water supply line to the
refrigerator.
WARNING
To prevent burns and product damage,
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
switch is in the OFF (O) position.
WARNING
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 on models without a wate filter and between
40 and 120 psi on models with a water filter.
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 filltration 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 (0,28 y 0,41 MPa)
less than 2.0~3.0 sec. to fill a cup of 7 oz (0.2 L)
capacity.
(Ice maker installed only)
WARNING
Wear eye protection during installation
to prevent injury.
If the water pressure from the reverse osmosis
system is less than 21 psi or 0,14 MPa takes
more than 4.0 sec
.
the reverse osmosis system is blocked.
.
Allow the storage tank on the reverse
usage.
.
If water pressure issues associated with
a reverse osmosis system persist, call a
.
All installations must be in accordance
with local plumbing code requirements.

What You Will Need

.
Copper Tubing,
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).
(about 8 feet [2.4 m] coiled into three
turns of about 10 in. [25 cm] diameter)
to allow the refrigerator to move out
from the wall after installation.
.
Power drill.
.
½ in. (13 mm) or
adjustable wrench.
.
Flat blade and Phillips
head screwdrivers.
.
Two ¼ in. (6.35 mm)
outer diameter compression
nuts and 2 ferrules (sleeves) to connect the
the refrigerator water valve.
cup of 7 oz capacity:
¼ in. (6.35 mm) outer
