Water Supply Requirements
A cold water supply with water pressure between 35 and 120 psi
(241 and 827 kPa) is required to operate the water dispenser and
ice maker. If you have questions about your water pressure, call
a licensed, qualied plumber.
NOTE: If the water pressure is less than what is required, the ow
of water from the water dispenser could decrease or ice cubes
could be hollow or irregular-shaped.
Reverse Osmosis Water Supply
IMPORTANT: The pressure of the water supply coming out
of a reverse osmosis system and supplying the water inlet valve
of the refrigerator needs to be between 35 and 120 psi (241 and
827 kPa).
If a reverse osmosis water ltration system is connected to
your home cold water supply, the water pressure to the reverse
osmosis system needs to be a minimum of 40 to 60 psi (276 to
414 kPa).
■ Check to see whether the sediment lter in the reverse
osmosis system is blocked. Replace the lter if necessary.
■ Allow the storage tank on the reverse osmosis system to rell
after heavy use. The tank capacity could be too small to keep
up with the requirements of the refrigerator.
NOTE: Faucet-mounted reverse osmosis systems are
not recommended.
■ If your refrigerator has a water lter, it may further reduce
the water pressure when used in conjunction with a reverse
osmosis system. Remove the water lter. See the “Water
Filtration System” section.
If you have questions about your water pressure, call a licensed,
qualied plumber.
Connect the Water Supply
Read all directions before you begin.
IMPORTANT:
■ Plumbing must be installed in accordance with the
International Plumbing Code and any local codes and
ordinances.
■ Copper and PEX tubing connections from the household
water line to the refrigerator are acceptable and will help
avoid off-taste or odor in your ice or water. Check for leaks.
If PEX tubing is used instead of copper, we recommend the
following Part Numbers: W10505928RP (7 ft [2.14 m] jacketed
PEX), 8212547RP (5 ft [1.52 m] PEX), or W10267701RP
(25 ft [7.62 m] PEX).
■ Install tubing only in areas where temperatures will remain
above freezing.
Tools Needed:
Gather the required tools and parts before starting installation.
■ Flat-blade screwdriver
■ 7/16" (11.11 mm) and 1/2" (12.7 mm) open-end wrenches or
two adjustable wrenches
■ 1/4" (6.35 mm) nut driver
NOTE: Do not use a piercing-type or 3/16" (4.76 mm) saddle
valve which reduces water ow and clogs easier.
Connect to Water Line
IMPORTANT: If you have turned the refrigerator on before the
water was connected, turn off the ice maker.
1. Unplug refrigerator or disconnect power.
4. Now you are ready to connect the copper tubing to the
shut-off valve. Use 1/4" (6.35 mm) O.D. (outside diameter)
soft copper tubing to connect the shut-off valve and the
refrigerator.
■ Ensure that you have the proper length needed for the job.
Be sure both ends of the copper tubing are cut square.
■ Slip compression sleeve and compression nut onto copper
tubing as shown. Insert end of tubing into outlet end squarely
as far as it will go. Screw compression nut onto outlet end
with adjustable wrench. Do not overtighten.
A. Compression sleeve
B. Compression nut
C. Copper tubing
5. Place the free end of the tubing into a container or sink and
turn on main water supply to ush out tubing until water is
clear. Turn off shut-off valve on the water pipe.
NOTE: Always drain the water line before making the nal
connection to the inlet of the water valve to avoid possible
water valve malfunction.
6. Bend the copper tubing to meet the water line inlet which
is located on the back of the refrigerator cabinet as shown.
Leave a coil of copper tubing to allow the refrigerator to be
pulled out of the cabinet or away from the wall for service.

D. Household supply line (1/2" [12.7 mm] minimum)
2. Turn off main water supply. Turn on nearest faucet long
enough to reduce water pressure in the water line.
3. Use a quarter-turn shut-off valve or the equivalent, served by
a 1/2"
(12.7 mm)
household supply line.
NOTE: To allow sufcient water ow to the refrigerator, a minimum
1/2" (12.7 mm) size household supply line is recommended.
