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):
■
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.”
If you have questions about your water pressure, call a licensed,
qualified plumber.
Connect the Water Supply
Read all directions before you begin.
IMPORTANT: If you turn the refrigerator on before the water line
is connected, turn the ice maker OFF.
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.
IMPORTANT:
■
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 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 tubing. Be sure
both ends of copper tubing are cut square.
5. Using a cordless drill, drill a
¹⁄₄
" hole in the cold water pipe
you have selected.
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
" 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
1. Create a service loop (minimum diameter of 2 ft [61 cm]) with
the copper tubing. Avoid kinks when coiling the copper
tubing.
2. Remove the plastic cap from water valve inlet port. Place a
compression nut and sleeve on the copper tubing.
3. Insert the end of the copper tubing into the water valve inlet
port. Shape tubing slightly so that the tubing feeds straight
into the port to avoid kinks.
4. Slide the compression nut over the sleeve and screw into the
water valve inlet port.
5. Using an adjustable wrench, hold the nut on the plastic water
line to keep it from moving. Then, with a second wrench turn
the compression nut on the copper tubing counterclockwise
to completely tighten. Do not overtighten.
6. Check connection by pulling on copper tubing. Attach copper
tubing to refrigerator cabinet with a “P” clamp. Turn on water
supply to refrigerator and check for leaks. Correct any leaks.
