Electrical Requirements

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 V, 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.”

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).

■

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 

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:

■

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 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 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).

■

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

NOTE:

 Do not use a piercing-type or 3/16" (4.76 mm) saddle 

valve which reduces water flow and clogs easier.

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.

WARNING

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.
