Water Pressure
A cold water supply with water pressure of between 30 and 120 psi
(207 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.
• If your refrigerator has a water dispenser: After installation is
complete, use the water dispenser to check the water pressure.
• With the water filter removed, dispense 1 cup (237 mL) of water. If
1 cup of water is dispensed in 8 seconds or less, the water pressure
to the refrigerator meets the minimum requirement.
• If it takes longer than 8 seconds to dispense 1 cup of water, the
water pressure to the refrigerator is lower than recommended. See
"Problem Solver" for suggestions.
Reverse Osmosis Water Supply
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 30 and 120 psi (207 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).
If the water pressure to the reverse osmosis system is less than 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 usage.
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" in the User
Instructions, User Guide, or Use & Care Guide.
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.
• 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" and 1/2" open-end wrenches or two adjustable wrenches
• 1/4" nut driver
Connect to Water Line
IMPORTANT: If you turn the refrigerator on before the water line is
connected, turn the ice maker OFF.
Style 1 (Recommended)
1. Unplug refrigerator or disconnect power.
2. Turn OFF main water supply. Turn ON nearest faucet long enough
to clear line of water.
Use a quarter-turn shutoff valve or the equivalent, served by a
1/2" copper household supply line.
NOTE: To allow sufficient water flow to the refrigerator, a minimum
1/2" size copper household supply line is recommended.

Now you are ready to connect the copper tubing to the shutoff valve.
Use 1/4" (6.35 mm) O.D. (outside diameter) 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.

Place the free end of the tubing into a container or sink, and turn on
main water supply to flush out tubing until water is clear. Turn off
shutoff valve on the water pipe.
NOTE: Always drain the water line before making the final connection
to the inlet of the water valve to avoid possible water valve
malfunction.
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.
Style 2
1. Unplug refrigerator or disconnect power.
2. Turn OFF main water supply. Turn ON nearest faucet long enough to
clear line of water.
3. Locate a 1/2" (1.27 cm) to 11/4" (3.18 cm) vertical cold water pipe near
the refrigerator.
IMPORTANT:
4.
• Make sure it is a cold water pipe.
• Horizontal pipe will work, but drill on the top side of the pipe, not
the bottom. This will help keep water away from the drill and
normal sediment from collecting in the valve.
Determine the length of copper tubing you need. Measure from the
connection on the lower rear corner of refrigerator to the water pipe.
Add 7 ft (2.1 m) to allow for cleaning. Use 1/4" (6.35 mm) O.D.
(outside diameter) copper tubing. Be sure both ends of copper tubing
are cut square.
