IMPORTANT:
■
All installations must meet local plumbing code requirements.
■
Use copper tubing and check for leaks. Install copper tubing
only in areas where the household temperatures will remain
above freezing.
Water Pressure
A cold water supply with water pressure of between 30 and 120
psi (207 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.
■
If your refrigerator has a water dispenser: After installation
is complete, use the water dispenser to check the water
pressure.
■
With the water filter removed, dispense 1 cup (237 mL) of
water. If 1 cup of water is dispensed in 8 seconds or less,
the water pressure to the refrigerator meets the minimum
requirement.
■
If it takes longer than 8 seconds to dispense 1 cup of
water, the water pressure to the refrigerator is lower than
recommended. See “Problem Solver” for suggestions.
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 30 and 120 psi (207 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 to 60 psi (276 to 414 kPa).
If the water pressure to the reverse osmosis system is less than
40 to 60 psi (276 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.
■
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” in the User Instructions, User Guide, or Use & Care
Guide.
If you have questions about your water pressure, call a licensed,
qualified plumber.
Connect Water Supply
Read all directions before you begin.
IMPORTANT:
■
Connect to potable water supply only.
■
Plumbing shall be installed in accordance with the
International Plumbing Code and any local codes and
ordinances.
■
The gray water tubing on the back of the refrigerator (which is
used to connect to the household water line) is a plastic
tube. Copper and plastic 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 plastic tubing is used instead of copper, we recommend the
following Whirlpool Part Numbers:
W10505928RP (7 ft [2.14 m] jacketed plastic),
8212547RP (5 ft [1.52 m] plastic), or
W10267701RP (25 ft [7.62 m] plastic).
■
Install tubing only in areas where temperatures will remain
above freezing.
TOOLS NEEDED:
Gather the required tools and parts before starting installation.
■
Flat-blade screwdriver
■
7⁄16" and 1/2" open-end wrenches or two adjustable
wrenches
■
1/4" nut driver
Connect to Water Line
IMPORTANT:
If you turn the refrigerator on before the water line
is connected, turn the ice maker OFF.
Style 1 (Recommended)
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 household supply line.
NOTE:
To allow sufficient water flow to the refrigerator, a
minimum 1/2" size copper household supply line is
recommended.
4.
Now you are ready to connect the copper tubing to the
shutoff valve. Use 1⁄4" (6.35 mm) OD soft copper tubing to
connect the shutoff valve and the refrigerator.
■
Ensure that you have the proper length needed for the job.
Be sure both ends of the copper tubing are cut square.
■
Slip compression sleeve and compression nut onto
copper tubing as shown. Insert end of tubing into outlet
end squarely as far as it will go. Screw compression nut
onto outlet end with adjustable wrench. Do not
overtighten.
5.
Place the free end of the tubing into a container or sink, and
turn on main water supply to flush out tubing until water is
clear. Turn off shutoff valve on the water pipe.
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.
