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 refrigera-
tor.
CAUTION
To prevent burns and product damange, only con-
nect 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

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 830 kPa) 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 os-
mosis system needs to be a minimum of 40 to 60 psi (280
and 420 kPa) , less than 2.0~3.0 sec. to fill a cup of 7 oz
(200cc) capacity.
CAUTION
Wear eye protection during installation to prevent
injury.
If the water pressure from the reverse osmosis system is less
than 20 psi (140 kPa) (takes more than 4.0 sec to fill a cup
of 7 oz (200cc) 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 plumb-
ing 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 refrig-
erator 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 refrig-
erator 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.
If your existing copper water
line has a flared fitting at the end, you will need an adapter
(available at plumbing supply stores) to connect the water
line
to the refrigerator OR you can
cut off the flared fitting with
a tube cutter and then use a
compression fitting.
Shutoff valve to connect to
the cold water line. The shutoff valve should have a water
inlet with a minimum inside diameter of 5/32 in. at the
point of connection to the COLD
WATER LINE. Saddle-type
shutoff valves are included in
many water supply kits. Before
purchasing, make sure a saddle-
type valve complies with your local plumbing codes.
NOTE
A self piercing saddle type water valve should not be
used.
