Gather the required tools and parts before starting installation.
Read and follow the instructions
provided with any tools listed
here.
TOOLS NEEDED:
•
Flat-blade screwdriver
•
1/4"Nut driver
•
7/le" and 1/2"Open-end or two
•
1/4"Drill bit
adjustable wrenches
•
Cordless drill
NOTE: Your refrigerator dealer has a kit available with a 1/4"
(6.35 mm) saddle-type shutoff valve, a union, and copper tubing.
Before purchasing, make sure a saddle-type
valve complies with
your local plumbing codes. Do not use a piercing-type
or ¾e"
(4.76 mm) saddle valve which reduces water flow and clogs more
easily.
IM PO RTANT:
•
All installations must meet local plumbing code requirements.
•
Use copper tubing and check for leaks. Install copper tubing
only in areas where the household temperatures will remain
above freezing.
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.
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 you have questions about your water pressure, call a licensed,
qualified plumber.
Read all directions before you begin.
IMPORTANT: If you turn the refrigerator on before the water line is
connected, turn the ice maker OFE
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. Locate a 1/2"to 1V4" (1.25 cm to 3.18 cm) vertical cold water
pipe near the refrigerator.
IM PO RTANT:
•
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.
4. Determine the length of copper tubing you need. Measure
from the connection on the lower left rear 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.
5. Using a cordless drill, drill a V4"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 washer makes a watertight seal. Do not
overtighten or you may crush the copper tubing.
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.
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. Coil the copper
tubing.
Connect to Refrigerator
1. Unplug refrigerator or disconnect power.
2. Attach the copper tube to the valve inlet using a compression
nut and sleeve as shown. Tighten the compression
nut. Do not
overtighten.
3. Use the tube clamp on the back of the refrigerator to secure
the tubing to the refrigerator as shown. This will help avoid
damage to the tubing when the refrigerator is pushed back
against the wall.
Turn shutoff valve ON.
4.
5. Check for leaks. Tighten any connections
(including
connections at the valve) or nuts that leak.

The ice maker is equipped with a built-in water strainer. If your
water conditions require a second water strainer, install it in
the 1/4"(6.35 mm) water line at either tube connection. Obtain
a water strainer from your nearest appliance dealer.
