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 21 psi
(1.5kgf/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.
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
2 ) on models without a water filter
and between 43 and 121 p.s.i. (3~8.5kgf/cm 2 ) on
models with a water filter.
