Maytag MBF2258DEH00, User Instructions

■

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:

■

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 Whirlpool 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.

■

If you turn on the refrigerator before the water line is 

connected, turn off the ice maker to avoid excessive noise or 

damage to the water valve.

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.

IMPORTANT:

■

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 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.

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" 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 the washer makes a watertight seal. Do not 

overtighten.

7. 

Slip the compression sleeve and compression nut on the 

copper tubing as shown. Insert the end of the tubing into the 

outlet end squarely as far as it will go. Screw compression nut 

onto outlet end with adjustable wrench. Do not overtighten or 

you may crush the copper tubing.

8. 

Place the free end of the tubing in a container or sink, and 

turn ON the main water supply. Flush the tubing until water is 

clear. Turn OFF the shutoff valve on the water pipe.
