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 flooding. Call a qualified 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 power switch is in the OFF (O) position.
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 (140 and 830 kPa) on models without a water filter and between 40 and 120 psi (280 and 830 kPa) on models with a water filter.
If a reverse osmosis water filtration 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 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
kgf/cm2 ~ 4.2 kgf/cm2, less than 2.0~3.0 sec. to fill 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 fill a cup of 7 oz capacity):
•Check to see if 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 concerning water pressure from reverse osmosis remains, call a licensed, qualified 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 sufficient 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 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 in. at the point of connection to the COLD WATER LINE.
make sure a
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.
