CONNECTING THE WATER LINE

BEFORE YOU BEGIN

This water line installation is not warranted by the

refrigerator or icemaker manufacturer. Follow

these instructions carefully to minimize the risk of

expensive water damage.

Water hammer (water banging in the pipes) in

house plumbing can cause damage to

refrigerator parts and lead to water leakage or

flooding. Call a qualified plumber to correct water

hammer before installing the water supply line to

the refrigerator.

To prevent burns and product damage, do not

hook up the water line to the hot water line.

If you use your refrigerator before connecting the

water line, make sure the icemaker power switch

is in the O (off) position.

Do not install the icemaker tubing in areas where

temperatures fall below freezing.

When using any electrical device (such as a power

drill) during installation, be sure the device is

double- insulated or grounded in a manner to

prevent the hazard of electric shock, or is battery-

powered.

All installations must be in accordance with local

plumbing code requirements.

NOTE: Wear eye protection.

WHAT YOU WILL NEED

• Copper Tubing, 1/4″ outer

diameter to connect the

refrigerator to the water

supply. Be sure both ends of

the tubing are cut square.

To determine how much tubing you need:

measure the distance from the water valve on the

back of the refrigerator to the water supply pipe.

Then add 8 feet (2.4 m). Be sure there is

sufficient extra tubing (about 8 feet [2.4 m] coiled

into 3 turns of about 10″ [25 cm] diameter) to

allow the refrigerator to move out from the wall

after installation.

• A cold water supply. The water pressure must

be between 20 and 120 p.s.i. on models without

a water filter and between 40 and 120 p.s.i. on

models with a water filter.

• Power drill.

• 1/2

″″

or adjustable

wrench.

• Straight- and

Phillips-blade

screwdriver.

• Two 1/4

″″

outer

diameter

compression nuts

and 2 ferrules

(sleeves) to connect

the copper tubing to the shutoff valve and the

refrigerator water valve.

• If your existing copper

water line has a flared

fitting at the end, you will

need an adapter (available

at plumbing supply stores)

to connect the water line to the refrigerator OR you

can cut off the flared fitting with a tube cutter and

then use a compression fitting.

• Shutoff valve to

connect to the cold

water line. The shutoff

valve should have a

water inlet with a

minimum inside diameter of 5/32″ at the point of

connection to the COLD WATER LINE. Saddle-

type shutoff valves are included in many water

supply kits. Before purchasing, make sure a

saddle-type valve complies with your local

plumbing codes.

INSTALLATION INSTRUCTIONS

Install the shutoff valve on the nearest frequently

used drinking water line.

SHUT OFF THE MAIN WATER SUPPLY

Turn on the nearest faucet to relieve the

pressure on the line.

2. CHOOSE THE VALVE LOCATION

Choose a location for the valve

that is easily accessible. It is best

to connect into the side of a

vertical water pipe. When it is

necessary to connect into a

horizontal water pipe, make the

connection to the top or side, rather than at

the bottom, to avoid drawing off any sediment

from the water pipe.

3. DRILL THE HOLE FOR THE VALVE

Drill a 1/4″ hole in the

water pipe (even if using

a self-piercing valve)

using a sharp bit. Remove

any burrs resulting from

drilling the hole in the

pipe. Take care not to

allow water to drain into the drill. Failure to drill

a 1/4″ hole may result in reduced ice

production or smaller cubes.
