REFRIGERATOR INSTALLATION
CONNECTING THE WATER LINE
NOTE: Water line installation is needed when the
Automatic Ice maker and/or Water Dispenser
features are available on your product.
BEFORE YOU BEGIN
This water line installation is not warranted by the
refrigerator or ice maker 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 ice maker power switch is in the OFF
(O) position. Do not install the ice maker 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 ice
maker 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.
