19 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
A cold water supply. The water pressure must
be between 20 and 120 psi (140 and 830 kPa)
on models without a water filter and between
40 and 120 psi (280 and 830kPa) 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 following 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 and 60 psi
( 280 and 420 kPa), less than 2.0~3.0 sec. to
fill a cup of 7 oz(200 cc) capacity.
If the water pressure from the reverse
osmosis system is less than 21 psi (145 kPa)
(takes more than 4.0 sec to fill a cup of 7 oz
(200 cc) capacity):
Check to see if the sediment filter in
the reverse osmosis system is blocked.
Replace the filter if necessary.
Allow the storage tank on the reverse
usage.
If the issue concerning water pressure
from reverse osmosis remains, call a
licensed, qualified plumber.
All installations must be in accordance
with local plumbing code requirements.
What You Will Need
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.
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 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 damange,
only connect the refrigerator water line to
a cold water supply.
