� Do not use a piercing-type or 3/16" (4.76 mm) saddle valve
which reduces water flow and clogs more easily.
� Use copper or PEX tubing and check for leaks. Install copper
or PEX tubing only in areas where the household temperatures
will remain above freezing.
� For models with water filters, the disposable water filter should
be replaced at least every 6 months.
Water Pressure
A cold water supply with water pressure of between 35 psi and
120 psi (241 kPa and 827 kPa) is required to operate the water
dispenser and ice maker. If you have questions about your water
pressure, call a licensed, qualified plumber.
NOTE: If the water pressure is less than what is required, the flow
of water from the water dispenser could decrease or ice cubes
could be hollow or irregular shaped.
Reverse Osmosis Water Supply
IMPORTANT: The pressure of the water supply coming out of a
reverse osmosis system going to the water inlet valve of the
refrigerator needs to be between 35 psi and 120 psi (241 kPa and
827 kPa).
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 psi to 60 psi (276 kPa to
414 kPa).
If the water pressure to the reverse osmosis system is less than
40 psi to 60 psi (276 kPa to 414 kPa):
� 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. The tank capacity could be too small to
keep up with the requirements of the refrigerator.
NOTE: Faucet-mounted reverse osmosis systems are not
recommended.
� If your refrigerator has a water filter, it may further reduce the
water pressure when used in conjunction with a reverse
osmosis system. Remove the water filter. See “Water Filtration
System”.
If you have questions about your water pressure, call a licensed,
qualified plumber.
Connect the Water Supply
Read all directions before you begin
IMPORTANT:
� Plumbing shall be installed in accordance with the
International Plumbing Code and any local codes and
ordinances.
� The water tubing on the back of the refrigerator (which is used
to connect to the household water line) is a PEX (cross-linked
polyethylene) tube. Copper and PEX tubing connections from
the household water line to the refrigerator are acceptable, and
will help avoid off-taste or odor in your ice or water. Check for
leaks. If PEX tubing is used instead of copper, we recommend
contacting Service to obtain current part numbers.
� Install tubing only in areas where temperatures will remain
above freezing.
� Connect to a potable water supply only.
Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after
the system. Systems certified for cyst reduction may be used
on disinfected waters that may contain filterable cysts.
Tools Needed:
Gather the required tools and parts before starting installation.
� Flat-blade screwdriver
� 7/16" and 1/2" Open-end or two
adjustable wrenches
� 1/4" Nut driver
� 1/4" Drill bit
� Cordless drill
NOTE: Your refrigerator dealer has a kit available with a 1/4"
(6.35 mm) saddle-type shutoff valve, a union, and copper or PEX
tubing. Before purchasing, make sure a saddle-type valve
complies with your local plumbing codes. Do not use a piercing-
type or 3/16" (4.76 mm) saddle valve which reduces water flow
and clogs more easily.
Connect to Water Line
IMPORTANT: If you turn on the refrigerator before the water line is
connected, turn off the ice maker.
1. Unplug refrigerator or disconnect power.
2. Turn off main water supply. Turn on nearest faucet long
enough to clear line of water.
3. Use a quarter-turn shutoff valve or the equivalent, served by a
1/2" copper or PEX household supply line.
NOTE: To allow sufficient water flow to the refrigerator, a
minimum 1/2" size copper or PEX household supply line is
recommended.
A. Bulb
B. Nut
C. Copper or PEX tubing (to
refrigerator)
D. Household supply line (½"
minimum)
