20 INSTALLATION
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
You will need a cold water supply. The water
pressure must be between 20 and 120 psi
(0.14 y 0.82 MPa) on models without a water
filter and between 40 and 120 psi (0.28 y 0.82 MPa)
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 to 60 psi (0,28 y 0,41 MPa)
less than 2.0~3.0 sec. to fill a cup of 7 oz (0.2 L)
capacity
If the water pressure from the reverse osmosis
system is less than 21 psi or 0,14 MPa takes more
than 4.0 sec to fill a cup of 7 oz (0,2 L) 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
osmosis system to refill after heavy
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.
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.
ENGLISH
What You Will Need
Copper Tubing,
.
¼ in. (6.35 mm) 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 three
turns of about 10 in. [25 cm] diameter)
to allow the refrigerator to move out
from the wall after installation.
Power drill.
.
½ in. (13 mm) or
.
adjustable wrench.
Flat blade and Phillips
.
head screwdrivers.
Two ¼ in. (6.35 mm)
.
outer diameter compression
nuts and 2 ferrules (sleeves) to connect the
copper tubing to the shutoff valve and
the refrigerator water valve.
