Electrical Requirements

Before you move your refrigerator into its final location, it is
important to make sure you have the proper electrical

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

Gather the required tools and parts before starting installation.
Read and follow the instructions provided with any tools listed



All installations must meet local plumbing code requirements.

Do not use a piercing-type or

³⁄₁₆" (4.76 mm) saddle valve

which reduces water flow and clogs more easily.

Use copper tubing and check for leaks. Install copper 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 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.

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).

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.”

If you have questions about your water pressure, call a licensed,
qualified plumber.

Connect the Water Supply

Read all directions before you begin.

IMPORTANT: If you turn the refrigerator on before the water line
is connected, turn the ice maker OFF.

Connect to Water Line

1. Unplug refrigerator or disconnect power.

2. Turn OFF main water supply. Turn ON nearest faucet long

enough to clear line of water.

3. Find a

¹⁄₂" to 1¹⁄₄" (12.7 mm to 31.8 mm) vertical cold water

pipe near the refrigerator.


Make sure it is a cold water pipe.

Horizontal pipe will work, but the following procedure
must be followed: Drill on the top side of the pipe, not the
bottom. This will help keep water away from the drill. This
also keeps normal sediment from collecting in the valve.

4. Determine the length of copper tubing you need. Measure

from the connection on the rear of the refrigerator to the
water pipe. Add 7 ft (2.1 m) to allow for cleaning. Use


(6.35 mm) O.D. (outside diameter) copper tubing. Be sure
both ends of copper tubing are cut square.

Flat-blade screwdriver

⁷⁄₁₆" and ¹⁄₂" Open-end or two
adjustable wrenches

¹⁄₄" Nut driver

¹⁄₄" Drill bit

Cordless drill

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.
