Electrical Requirements

WARNING

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

A115 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 are 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 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:

■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.

TOOLS NEEDED:

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

■	Flat-blade screwdriver	■	¹⁄₄" Nut driver
■	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 easily.

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.

IMPORTANT:

■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.

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.
