■ 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 and Care Guide.
If you have questions about your water pressure, call a licensed,
qualified plumber.
Connect Water Supply
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 Whirlpool 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" 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.
3. Use a quarter-turn shut-off 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.

A. Bulb
B. Nut
C. Copper tubing (to refrigerator)
D. Household supply line (1/2" minimum)
4. Now you are ready to connect the copper tubing to the
shut-off valve. Use 1/4" (6.35 mm) OD 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.

C. Copper tubing
5. 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 shut-off 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.
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.
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 1¼" (3.18 cm) vertical cold water
pipe near the refrigerator.
IMPORTANT:
■ 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.
