CONNECTING THE WATER LINE
NOTE: Water line installation is needed when the
Automatic Icemaker and/or Water Dispenser
features are available on your product.
BEFORE YOU BEGIN
This water line installation is not warranted by the
refrigerator or icemaker manufacturer or seller.
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 OFF
(O) 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 MUST be in accordance with local
plumbing code requirements.
NOTE: Wear eye protection.
• If a reverse osmosis water filtration system is
connected to your cold water supply, the water line
installation is not warranted by the refrigerator or
icemaker manufacturer or seller. 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•f/cm² ~ 4,2 kg•f/
cm² , less than 2~3 sec to fill a cup of 7 oz. capacity).
If the water pressure from the reverse osmosis system
is less than 21 PSI (1,5 kg•f/cm², more than 4 sec to
fill 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.
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 20 and 120 PSI (1,4 bar and 8,2 bar) on
models without a water filter and between 40 and 120
PSI (2,8 bar and 8,2 bar) on models with a water filter.
• Power drill.
• 1/2” (12,7 mm) or
Adjustable Wrench.
• Flat head and Phillips screwdrivers.
• Two 1/4” (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.
• 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”(3,96 mm) 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.
INSTALLATION INSTRUCTIONS
WARNING: Connect to potable water supply only.
1. SHUTOFF THE MAIN WATER SUPPLY
Turn on the nearest faucet to relieve the pressure on
the line.
2. CHOOSE THE VALVE LOCATION
Choose a location for the valve that is easily
accessible. It is best to connect into
the side of a vertical water pipe. When
it is necessary to connect into a
horizontal water pipe, make the
connection to the top or side, rather
than at the bottom, to avoid drawing
off any sediment from the water pipe.
