Water Supply Requirements

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

TOOLS NEEDED:

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.
IMPORTANT:

■

All installations must meet local plumbing code requirements.

■

Use copper tubing and check for leaks. Install copper tubing
only in areas where the household temperatures will remain
above freezing.

Water Pressure

A cold water supply with water pressure of 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.

■

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 Water Supply

Read all directions before you begin.
IMPORTANT:

■

Plumbing shall be installed in accordance with the
International Plumbing Code and any local codes and
ordinances.

■

Use copper tubing or Whirlpool supply line, Part Number
8212547RP, and check for leaks.

■

Install tubing only in areas where temperatures will remain
above freezing.

TOOLS NEEDED:

Gather the required tools and parts before starting installation.

Connect to Water Line

IMPORTANT: If you turn the refrigerator on before the water line is
connected, turn the ice maker OFF.
1. Unplug refrigerator or disconnect power.

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

enough to clear line of water.

3. Use a quarter-turn shutoff valve or the equivalent, served by a

¹⁄₂

" copper household supply line.

NOTE: To allow sufficient water flow to the refrigerator, a
minimum

¹⁄₂

" size copper household supply line is

recommended.

4. Now you are ready to connect the copper tubing to the shutoff

valve. Use

¹⁄₄

" (6.35 mm) OD soft copper tubing to connect the

shutoff valve and the refrigerator.

■

Ensure that you have the proper length needed for the job.
Be sure both ends of the copper tubing are cut square.

■

Slip compression sleeve and compression nut onto
copper tubing as shown. Insert end of tubing into outlet
end squarely as far as it will go. Screw compression nut
onto outlet end with adjustable wrench. Do not
overtighten.

5. Place the free end of the tubing into a container or sink, and

turn on main water supply to flush out tubing until water is
clear. Turn off shutoff valve on the water pipe.
NOTE: Always drain the water line before making the final
connection to the inlet of the water valve, to avoid possible
water valve malfunction.

6. Bend the copper tubing to meet the water line inlet, which is

located on the back of the refrigerator cabinet as shown.
Leave a coil of copper tubing to allow the refrigerator to be
pulled out of the cabinet or away from the wall for service.
