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 pooding. Call a qualioed
plumber to correct water hammer before installing the
water supply line to the refrigerator.
CAUTION: To prevent burns and product damage,
only connect the refrigerator water line to a cold
water supply.
If you use your refrigerator before connecting the water
line, make sure the icemaker is turned OFF at the control
panel.
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. If the refrigerator is installed in an area
with low water pressure (below 20 psi), you can install a
booster pump to compensate for the low pressure.
If a reverse osmosis water oltration 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 oltration 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 oll 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 oll a cup of 7 oz or 198 cc capacity):
v Check to see if the sediment olter in the reverse osmosis
system is blocked. Replace the olter if necessary.
v Allow the storage tank on the reverse osmosis system to
reoll after heavy usage.
v If the issue concerning water pressure from reverse
osmosis remains, call a licensed, qualioed plumber.
v All installations must be in accordance with local
plumbing code requirements.
CAUTION: Wear eye protection during installation to
prevent injury.
WHAT YOU WILL NEED
v Copper Tubing, ¼ in. outer
diameter, to connect the
refrigerator to the water supply. Be
sure both ends of the tubing are
cut square.
v 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 suècient 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.
v Power drill
v in or adjustable wrench
v Flat blade and Phillips head screwdrivers
v Two in outer diameter
compression nuts and
ferrules (sleeves to
connect the copper tubing
to the shutoç valve and the
refrigerator water valve.
v If your existing copper water
line has a pared otting 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 oç the pared
otting with a tube cutter and
then use a compression otting.
v Shutoç valve to connect to the cold water line. The
shutoç 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 shutoç 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.
WARNING
Electrical Shock Hazard
When using any electrical device (such as a power
drill) during installation, be sure the device is battery
powered, double insulated or grounded in a manner
that will prevent the hazard of electric shock.
