CONNECTING THE WATER SUPPLY
w
WARNING
Connect to safe drinking water supply
only.
• The water pressure must be between 20 and
120 p.s.i. (1.4~8.4 kgf/cm
2
) on models without
a water filter and between 43 and 121 p.s.i.
(3~8.5 kgf/cm
2
) on models with a water filter.
• If water pressure does not reach 20 psi
(1.4 kgf/cm
2
) 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
2
~
4.2 kgf/cm
2
, 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 20 psi (1.4 kgf/cm
2
, 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 20~120 psi
(1.4~8.4 kgf/cm
2
) on models without a water filter
and between 43 and 121 p.s.i. (3~8.5 kgf/cm
2
) on
models with a water filter.
