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, qualified plumber.
NOTE:
If the water pressure is less than what is required, the flow
of water from the water dispenser could decrease or ice cubes
could be hollow or irregular shaped.

IMPORTANT:
The pressure of the water supply coming out of a
reverse osmosis system going to the water inlet valve of the
refrigerator needs to be between 35 and 120 psi (241 and
827 kPa).
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 (276 to 414 kPa).
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 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 filter, it may further reduce the
water pressure when used in conjunction with a reverse
osmosis system. Remove the water filter. See “Water
Filtration System.”
If you have questions about your water pressure, call a licensed,
qualified plumber.

Read all directions before you begin.
IMPORTANT:
Plumbing shall be installed in accordance with the
International Plumbing Code and any local codes and
ordinances.
The gray water tubing on the back of the refrigerator (which is
used to connect to the household water line) is a PEX
(cross-linked polyethylene) tube. 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
" and " open-end wrenches or two adjustable wrenches
" nut driver
NOTE:
Do not use a piercing-type or
" (4.76 mm) saddle valve
which reduces water flow and clogs easier.

(
IMPORTANT:
If you turn the refrigerator on before the water is
connected, turn the ice maker OFF.
1.
Unplug refrigerator or disconnect power.
2.
Turn OFF main water supply. Turn ON nearest faucet long
enough to clear line of water.
3.
Use a quarter-turn shutoff valve or the equivalent, served by a
" household supply line.
NOTE:
To allow sufficient water flow to the refrigerator, a
minimum " size household supply line is recommended.
4.
Now you are ready to connect the copper tubing to the
shutoff valve. Use " (6.35 mm) OD soft copper tubing to
connect the shutoff 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.
