CONNECTING THE WATER LINE
20
BEFORE YOU BEGIN
This water line installation is not warranted by the
refrigerator or icemaker manufacturer. 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
lead to water leakage or flooding. Call a qualified
plumber to correct water hammer before installing the
water supply line to the refrigerator
.
To prevent burns and product damage, do not hook up
the water line to the hot water line.
If you use your refrigerator before connecting the water
line, make sure the icemaker power switch is in the O
(off) position.
Do not install the icemaker tubing in areas where
temperatures fall below freezing.
When using any electrical device (such as a power
drill) during installation, be sure the device is double-
insulated or grounded in a manner to prevent the hazard
of electric shock, or is battery-powered.
All installations local must be in accordance with
plumbing code requirements.
NOTE: Wear eye protection.
WHAT YOU WILL NEED
Copper Tubing, 1/4” (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 3 turns of about 10 [25 cm]
diameter) to allow the refrigerator to move out from the
wall after installation.
Be sure that the kit you select allows at least 8 feet
(2.4 m) as described above.
A cold water supply .The water pressure must be
between 0.137 and 0.82 MPa (20 and 120 PSI or 1.4
bar and 8.2 bar) on models without a water filter and
between 0.275 and 0.82 MPa (40 and 120 PSI or 2.8

cut off the flared fitting with a tube cutter and then use
a compression fitting.

included in many water supply kits. Before purchasing,
make sure a saddle-type valve complies with your

• If a reverse osmosis water filtration system is
connected to your cold water supply. This water line
installation is not warranted by the refrigerator or
icemaker manufacturer. Follow next instruction
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 (2.8 kg

If the water pressure from the reverse osmosis system
is less than 21 PSI (1.5 kg

a cup of 7 oz capacity).
• Check to see whether 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 about water pressure from reverse osmosis
remains, call a licensed, qualified plumber.
