Water Pressure
A cold water supply with water pressure of 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.
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 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).
If the water pressure to the reverse osmosis system is less than
40 to 60 psi (276 to 414 kPa):
IMPORTANT: Flush the water system before calibrating
Measured Fill. See “Flush the Water System” in the Owner’s
Manual.
If you have questions about your water pressure, call a licensed,
qualified plumber.
Connect the 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 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
contacting Service to obtain current part numbers.
� Install tubing only in areas where temperatures will remain
above freezing.
� If you turn on the refrigerator before the water line is
connected, turn off the ice maker to avoid excessive noise or
damage to the water valve.
Connect to Water Line
1. Unplug refrigerator or disconnect power.
2. Turn off main water supply. Turn on nearest faucet long
enough to clear line of water.
3. Find a 1/2" to 1 1/4" (12.7 mm to 31.8 mm) vertical cold water
pipe near the refrigerator.
� Make sure it is a cold water pipe.
� Horizontal pipe will work, but the following procedure must
be followed: Drill on the top side of the pipe, not the
bottom. This will help keep water away from the drill. This
also keeps normal sediment from collecting in the valve.
4. Determine the length of copper tubing you need. Measure
from the connection on the lower right rear of the 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 or PEX tubing.
Be sure both ends of copper or PEX tubing are cut square.
5. Using a cordless drill, drill a 1/4" (6.35 mm) hole in the cold
water pipe you have selected.
A. Cold water pipe
B. Pipe clamp
C. Copper or PEX tubing
D. Compression nut
E. Compression sleeve
F. Shutoff valve
G. Packing nut
6. Fasten the shutoff valve to the cold water pipe with the pipe
clamp. Be sure the outlet end is solidly in the 1/4" (6.35 mm)
drilled hole in the water pipe and that the washer is under the
pipe clamp. Tighten the packing nut. Tighten the pipe clamp
screws slowly and evenly so the washer makes a watertight
seal. Do not overtighten.
7. Slip the compression sleeve and compression nut on the
copper tubing as shown. Insert the end of the tubing into the
outlet end squarely as far as it will go. Screw compression nut
onto outlet end with adjustable wrench. Do not overtighten or
you may crush the copper tubing.
8. Place the free end of the tubing in a container or sink, and turn
on the main water supply. Flush the tubing until water is clear.
Turn off the shutoff valve on the water pipe.
Connect to Refrigerator
Depending on your model, the water line may come down from
the top or up from the bottom. Follow the connection instructions
for your model.
Style 1
1. Remove plastic cap from water valve inlet port. Attach the
copper tube to the valve inlet using a compression nut and
sleeve as shown. Tighten the compression nut. Do not
overtighten. Confirm copper tubing is secure by pulling on
copper tubing.
2. Create a service loop with the copper tubing. Avoid kinks
when coiling the tubing. Secure copper or PEX tubing to
refrigerator cabinet with a “P” clamp.
A. Copper or PEX
tubing
B. “P” clamp
C.
Compression nut
D. Compression sleeve
3. Turn on water supply to refrigerator and check for leaks.
Correct any leaks.
Style 2
1. Create a service loop (minimum diameter of 2 ft. [61 cm]) with
the copper or PEX tubing. Avoid kinks when coiling the tubing.
