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 damage, only
connect the refrigerator water line to a cold
water supply.
CAUTION
Do not install the icemaker tubing in areas
where temperatures fall below freezing.

Water Pressure

You will need a cold water supply. The water
pressure must be between 20 and 120 psi ( 138
– 827 kPa ) on models without a water filter and
between 40 and 120 psi ( 276 – 827 kPa ) on
models with a water filter. If the water pressure
does not reach the minimum required pressure,
a separate booster pump may be required
for normal automatic icemaker and cool water
dispensing operation.
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 these 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 - 413 kPa,
or less than 2.0~3.0 sec. to fill a cup of 7 oz
capacity).
CAUTION
Wear eye protection during installation to
prevent injury.
If the water pressure from the reverse osmosis
system is less than 21 psi or 1.5 kgf/cm2 (takes
more than 4.0 sec to fill a cup of 7 oz capacity):
y Check to see if the sediment filter in
the reverse osmosis system is blocked.
Replace the filter if necessary.
y Allow the storage tank on the reverse
osmosis system to refill after heavy usage.
y If the issue concerning water pressure
from reverse osmosis remains, call a
licensed, qualified plumber.
y All installations must be in accordance
with local plumbing code requirements.

What You Will Need

y Copper Tubing, ¼ in. 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 in. [25 cm] diameter) to
allow the refrigerator to move out from
the wall after installation. Keep the total
length of the feed water pipe tube within
26 ft (8 m). Be careful to avoid getting a
kink in the tube. If the tube is longer than
26 ft (8 m), it may cause the water feed to
malfunction.
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.
