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 - 414 kPa).
If the water pressure to the reverse osmosis system is less than
40 to 60 psi (276 - 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.

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. Locate a ½" to 1

¹⁄₄

" (1.25 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 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 grounded 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 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 prevent
damage to the tubing when the refrigerator is pushed back
against the wall.

4. Turn shutoff 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.

Complete the Installation

Plug in refrigerator or reconnect power.
NOTE: Allow 24 hours to produce the first batch of ice. Discard
the first three batches of ice produced. Allow 3 days to completely
fill ice container.
