Water Supply Requirements

Read all directions before you begin.

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, ⁷⁄₁₆" and ¹⁄₂" open-end

wrenches or 2

adjustable wrenches, ¹⁄₄" nut driver and drill bit,

cordless drill.

IMPORTANT:

■ If you turn on the refrigerator before the water line is

connected, turn off the ice maker.

■ 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.

NOTE: Your refrigerator dealer has a kit available with a ¹⁄₄"

(6.35

mm) saddle-type shut-off 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 ³⁄₁₆"

(4.76

mm) saddle valve which reduces water flow and clogs more

easily.

Water Pressure

IMPORTANT: A cold potable water supply with water pressure

between 30 and 120 psi (207 and 827 kPa) is required to operate

the ice maker.

NOTE: If the water pressure is less than what is required, ice

cubes could be hollow or irregular shaped.

If you have questions about your water pressure, call a licensed,

qualified plumber.

Reverse Osmosis Water Supply

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 ice maker is still not operating properly:

■ 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.

Connect the Water Supply

(on some models)

Read all directions before you begin.

IMPORTANT: 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. Locate a ¹⁄₂" to 1¹⁄₄" (1.27 cm to 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.

4. Determine the length of copper tubing you will need. Measure

from the connection on 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 ¹⁄₄" (6.35 mm) hole in the cold

water pipe you have selected.

6. Fasten the shut-off 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 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.

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 shut-off valve on the water pipe. Coil the copper

tubing.

Connect to Refrigerator

NOTE: On kit models, assemble water valve to refrigerator

according to kit instructions.

Style 1

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.

4. Turn shut-off valve on.

5. Check for leaks. Tighten any connections (including

connections at the valve) or nuts that leak.

6. 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.
