Electrical Requirements

Electrical Shock Hazard
Plug into a grounded 3 prong outlet.
Do not remove ground prong.
Do not use an adapter.
Do not use an extension cord.
Failure to follow these instructions can result in death,
fire, or electrical shock.

Water Supply Requirements

A cold water supply with water pressure between 35 and 120 psi
(241 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 and 120 psi (241 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).

Connect the Water Supply

Read all directions before you begin.
Plumbing shall be installed in accordance with the
International Plumbing Code and any local codes and
The gray 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 the
following Whirlpool Part Numbers:
W10505928RP (7 ft [2.14 m] jacketed PEX),
8212547RP (5 ft [1.52 m] PEX), or
W10267701RP (25 ft [7.62 m] PEX).
Before you move your refrigerator into its final location, it is
important to make sure you have the proper electrical connection.
Recommended Grounding Method
A 115 volt, 60 Hz, AC only 15 or 20 A fused, grounded electrical
supply is required. It is recommended that a separate circuit
serving only your refrigerator be provided. Use an outlet that
cannot be turned off by a switch. Do not use an extension cord.
NOTE: Before performing any type of installation, cleaning, or
removing a light bulb, turn Cooling OFF, and then disconnect the
refrigerator from the electrical source. When you have finished,
reconnect the refrigerator to the electrical source and turn
Cooling ON. See "Using the Controls."
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 use. The tank capacity could be too small to keep
up with the requirements of the refrigerator.
NOTE: Faucet mounted reverse osmosis systems are not
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
If you have questions about your water pressure, call a licensed,
qualified plumber.
Install tubing only in areas where temperatures will remain
above freezing.
Gather the required tools and parts before starting installation.
Flat-blade screwdriver
7⁄16" and 1/2" open-end wrenches or two adjustable
1/4" nut driver
NOTE: Do not use a piercing-type or 3/16" (4.76 mm) saddle
valve which reduces water flow and clogs easier.
