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
fl
ooding. Call a quali
fi
ed 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.
Connect to a potable water supply only.
If you use your refrigerator before connecting the water
line, make sure the icemaker power switch is in the
OFF (O)
position.
Do not install the icemaker tubing in areas where
temperatures fall below freezing.
WATER PRESSURE
Connect to the cold water supply.
The water pressure
must be between 20 and 120 psi (138 to 827 kPa) on
models without a water
fi
lter and between 40 and 120 psi
(276 to 827 kPa) on models with a water
fi
lter.
If a
reverse osmosis water
fi
ltration 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
fi
ltration 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
kgf/cm
2
~ 4.2 kgf/cm
2
, less than 2.0~3.0 sec. to
fi
ll a cup
of 7 oz capacity).
If the water pressure from the reverse osmosis system is less
than 21 psi or 1.5 kgf/cm2 (takes more than 4.0 sec to
fi
ll a
cup of 7 oz capacity):
• Check to see if the sediment
fi
lter in the reverse osmosis
system is blocked. Replace the
fi
lter if necessary.
• Allow the storage tank on the reverse osmosis system to
re
fi
ll after heavy usage.
• If the issue concerning water pressure from reverse
osmosis remains, call a licensed, quali
fi
ed plumber.
• All installations must be in accordance with local
plumbing code requirements.
CAUTION:
Wear eye protection during installation to
prevent injury.
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 su
ffi
cient 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 shuto
ff
valve and the
refrigerator water valve.
• If your existing copper water
line has a
fl
ared
fi
tting 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 o
ff
the
fl
ared
fi
tting with
a tube cutter and then use a
compression
fi
tting.
• Shuto
ff
valve to connect
to the cold water line.
The
shuto
ff
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 shuto
ff
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.
