INSTALLATION
ENGLISH
CAUTION
Wear eye protection during installation
to prevent injury.
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.
If you use your refrigerator before connecting
the water line, make sure the icemaker power
switch is in the OFF (O) position.
Water Pressure
The water pressure must be 20~120 psi or
138~827 kPa or 1.4~8.4 kgf/cm² on models
without a water filter and 40~120 psi or 276~827
kPa or 2.8~8.4 kgf/cm² 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 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).
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
Copper Tubing,
y
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
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.
Power drill.
y
½ in. or adjustable
y
wrench.
Flat blade and Phillips
y
head screwdrivers.
Two ¼ in. outer
y
diameter compression
nuts and 2 ferrules (sleeves)
to connect the
copper tubing to the shutoff valve and
the refrigerator water valve.
CAUTION
Do not install the icemaker tubing in
areas where temperatures fall below
freezing.
CAUTION
To prevent burns and product damage,
only connect the refrigerator water line to
a cold water supply.
