CONNECTING THE WATER SUPPLY

wWARNING

Connect to safe drinking water supply

only.

• The water pressure must be between 21 and

121 p.s.i. (1.5~8.5 kgf/cm

) on models without

a water filter and between 43 and 121 p.s.i.

(3~8.5 kgf/cm

) on models with a water filter.

• If water pressure does not reach 21 psi

(1.5 kgf/cm

) or falls below, it is necessary to

purchase a separate pressure pump for normal

automatic icemaker and water dispensing

operation.

• It is recommended that the total length of the water

feed tube does not exceed 26 ft. (8 m).

• Install the water supply line where it will not be

affected by heat.

• If a reverse osmosis water filtration system is

connected to your cold water supply, This water

line installation is not warranted by the refrigerator

or icemaker manufacturer. Follow next instructions

carefully to minimize the risk of expensive water

damage.

• 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 (2.8 kgf/cm

4.2 kgf/cm

, less than 2.0~3.0sec to fill a cup of

7oz capacity).

If the water pressure from the reverse osmosis

system is less than 21 psi (1.5 kgf/cm

, more than

4.0sec to fill a cup of 7oz capacity):

• 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 the issue about water pressure from reverse

osmosis remains, call a licensed, qualified plumber.

IMPORTANT: Read all directions thoroughly before

you begin.

• If operating the refrigerator before installing the

water connection, turn the icemaker to the OFF

position to prevent operation without water.

• All installations must be in accordance with local

plumbing code requirements.

• Use copper tubing and check for leaks.

• Install tubing only in areas where temperatures will

remain above freezing.

• It may take up to 24 hours for the icemaker to

begin producing ice.

Tools Required

• Standard screwdriver

• 7/16-in. and 1/2-in. open-end wrenches or two

adjustable wrenches

• 1/4-in. nut driver

• 1/4-in. drill bit

• Hand drill or electric drill (properly grounded)

NOTE: Refrigerator dealers offer a kit with a 1/4-in.

saddle-type shutoff valve, a union, and copper

tubing. Before purchasing, make sure a saddle-type

valve complies with local plumbing codes.

Do not use a piercing-type or 3/16-in. saddle

valve which reduces water flow and clogs more

easily.

NOTE: The Commonwealth of Massachusetts

Plumbing Code 248CMR shall be adhered to.

Saddle valves are illegal and use is not permitted in

Massachusetts. Consult with your licensed plumber.

Cold Water Supply

• The icemaker water valve contains a flow washer

which is used as a water pressure regulator.

• The icemaker needs to be connected to a cold

water line with water pressure between 21~121 psi

(1.5~8.5 kgf/cm

) on models without a water filter

and between 43 and 121 p.s.i. (3~8.5 kgf/cm

) on

models with a water filter.
