22 INSTALLATION
Connecting the Water Line
Before Beginning
This water line installation is not covered by the 
refrigerator warranty. Follow these instructions 
carefully to minimize the risk of expensive water 
damage.
If necessary, call a qualified plumber to correct 
water hammer before installing the water supply 
line to the refrigerator. Water banging in the pipes 
(water hammer) in residential plumbing can cause 
damage to refrigerator parts and lead to water 
leakage or flooding.
• Turn the icemaker OFF if the refrigerator will be 
used before the water line is connected.
• Do not install the icemaker tubing in areas 
where the ambient temperatures fall below 
freezing.
• Connect to potable water supply only.
• To prevent burns and product damage, only 
connect the refrigerator water line to a cold 
water supply.
• Wear eye protection during installation to 
prevent injury.
Water Pressure
You will need a cold water supply.
Water Pressure
• Models with water filter:
-  20 - 120 psi (138 - 827 kPa)
• Where reverse osmosis water filtration 
system is connected to a cold water supply:
-  40 - 60 psi minimum to reverse osmosis 
system (2.8 kgf/cm
2
 - 4.2 kgf/cm
2
, or less than 
2 - 3 seconds to fill a cup of 7 oz capacity)
If the water pressure from the reverse osmosis 
system is less than 20 psi or 138 kPa or 1.4 kgf/cm
2
 
(takes more than 4 seconds to fill a cup of 7 oz or 
198 cc 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 water pressure remains low, call a 
licensed, qualified plumber.
• All installations must be in accordance with local 
plumbing code requirements.
Supplies Needed
• Copper or PEX 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 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, purchase an adapter (available 
at plumbing supply stores) to connect the water 
line to the refrigerator OR cut off the flared 
fitting with a tube cutter and 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. 
Saddle-type shutoff valves are included in many 
water supply kits. Before purchasing, make sure
