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.
If you use your refrigerator before connecting
the water line, make sure the icemaker power
switch is in the OFF (O) position.
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).
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 co n n e c t th e r e f r i ge ra to r t o
the wat er supply. Be sure both
ends of the tubing are cut square.
To determine how
much tubing you need:
measure the distanc
e
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 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.
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.
CAUTION
Wear eye protection during installation to
prevent injury.
