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 ooding. Call a quali ed 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.
If you use your refrigerator before connecting
the water line, make sure the icemaker power
switch is in the OFF (O) position.
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 on
models without a water lter and between 40
and 120 psi on models with a water lter.
If a reverse osmosis water ltration system is
connected to your cold water supply, this water
line installation is not covered by the refrigerator
warranty. Follow the following instructions
carefully to minimize the risk of expensive water
damage.
If a reverse osmosis water ltration 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 (2.8 kgf/cm2
~ 4.2 kgf/cm2, or less than 2.0~3.0 sec. to ll 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 ll a cup of 7 oz capacity):
 Check to see if the sediment lter in
the reverse osmosis system is blocked.
Replace the lter if necessary.
 Allow the storage tank on the reverse
osmosis system to re ll after heavy
usage.
 If the issue concerning water pressure
from reverse osmosis remains, call a
licensed, quali ed plumber.
 All installations must be in accordance
with local plumbing code requirements.

What You Will Need

 Copper Tubing, ¼ in. outer diameter,
t o c o n n e c t t h e r e f r i g e r a t o r t o
t h e w a t e r s u p p l y. B e s u r e b o t h
ends of the tubing are cut square.
To d e t e r m i n e h o w
much tubing you need:
measure the distance
from the water valve
on the back of the
r e f r i g e r a t o r t o t h e
water supply pipe. Then, add 8 feet (2.4
m). Be sure there is su cient 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.
 Power drill.
 ½ in. or adjustable
wrench.
 Flat blade and Phillips
head screwdrivers.
 Two ¼ in. outer
diameter compression
nuts and 2 ferrules
(sleeves) to connect the copper tubing to
the shuto valve and the refrigerator water
valve.
