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.
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-amp 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 Control(s).”

Water Supply Requirements

A cold water supply with water pressure 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.
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. The tank capacity could be too low to keep
up with the requirements of the refrigerator.
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.

Connect the Water Supply

Read all directions before you begin.
All installations must meet local plumbing code requirements.
Use copper tubing or Whirlpool supply line, Part Number
8212547RP, and check for leaks.
Install copper tubing only in areas where the temperatures will
remain above freezing.
Gather the required tools and parts before starting installation.
Read and follow the instructions provided with any tools listed
¹⁄₄" Nut driver
Flat-blade screwdriver
⁷⁄₁₆" and ¹⁄₂" Open-end or two
¹⁄₄" Drill bit
adjustable wrenches
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 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
Connect to Water Line
Style 1
1. Unplug refrigerator or disconnect power.
2. Turn OFF main water supply. Turn ON nearest faucet long
enough to clear line of water.
3. Locate a ½" to 1¹⁄₄" (1.25 cm to 3.18 cm) vertical cold water
pipe near the refrigerator.
Make sure it is a cold water pipe.
Horizontal pipe will work, but drill on the top side of the
pipe, not the bottom. This will help keep water away from
the drill and normal sediment from collecting in the valve.
4. Determine the length of copper tubing you need. Measure
from the connection on the lower left rear of refrigerator to the
water pipe. Add 7 ft (2.1 m) to allow for cleaning. Use ¹⁄₄"
(6.35 mm) O.D. (outside diameter) copper tubing. Be sure both
ends of copper tubing are cut square.
5. Using a cordless drill, drill a ¹⁄₄" hole in the cold water pipe you
have selected.
A. Cold water pipe
E. Compression sleeve
B. Pipe clamp
F. Shutoff valve
C. Copper tubing
G. Packing nut
D. Compression nut
6. Fasten the shutoff valve to the cold water pipe with the pipe
clamp. Be sure the outlet end is solidly in the ¹⁄₄" (6.35 mm)
drilled hole in the water pipe and that the washer is under the
pipe clamp. Tighten the packing nut. Tighten the pipe clamp
screws slowly and evenly so washer makes a watertight seal.
Do not overtighten or you may crush the copper tubing.
