CONNECTING THE WATER SUPPLY
w WARNING
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 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 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.
• 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 2.0~3.0 sec 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 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 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.
CONNECTING THE WATER LINES
IMPORTANT: Before connecting the tubing to the water line,
unplug the refrigerator or disconnect the power.
• Turn off the main water supply and open the nearest faucet
to relieve pressure in the line. Opening an outside faucet may
help drain water from the line in the house.
• Find a 1/2-in. vertical COLD water pipe near the refrigerator.
NOTE: A horizontal pipe will work, but the following precaution
must be taken: drill on the top of the pipe, not the bottom. This
will help keep water away from the drill and also keep normal
sediment from collecting in the valve.
• To determine the length of copper tubing you will need,
measure from the connection on the lower left rear of the
refrigerator to the water pipe. Add 7 ft. (2.1 m) to allow for
moving the refrigerator for cleaning. Use 1/4-in. O.D. (outside
diameter) copper tubing. Be sure both ends of the copper
tubing are cut square.
• Using a drill, drill a 1/4-in. hole in the cold water pipe you
have selected.
