Check with your local building authority for recommendations on 

water lines and associated materials prior to installing your new 

refrigerator.

Ensure that your water supply line connections comply with all 

local plumbing codes.

• 

Copper or Stainless Steel braided tubing is recommended 

for the water supply line. Water supply tubing made of ¼ inch 

plastic is not recommended to be used. Plastic tubing greatly 

increases the potential for water leaks, and the manufactur-

er will not be responsible for any damage if plastic tubing is 

used for the supply line.

• 

DO NOT install water supply tubing in areas where tempera-

tures fall below freezing.

• 

Chemicals from a malfunctioning softener can damage the 

ice maker. If the ice maker is connected to soft water, ensure 

that the softener is maintained and working properly.

To avoid electric shock, which can cause death or severe 

personal injury, disconnect the refrigerator from electrical 

power before connecting a water supply line to the refriger-

ator.

1.  Disconnect refrigerator from electric power source.

2.  Place end of water supply line into sink or bucket. Turn ON 

water supply and flush supply line until water is clear. Turn 

OFF water supply at shutoff valve.

3.  Remove plastic cap from water valve inlet and discard cap.

4.  If you use copper tubing - Slide brass compression nut, 

then ferrule (sleeve) onto water supply line. Push water sup-

ply line into water valve inlet as far as it will go (¼ inch / 6.4 

mm). Slide ferrule (sleeve) into valve inlet and finger tighten 

compression nut onto valve. Tighten another half turn with a 

wrench; DO NOT over tighten. See Figure 28. 

       

If you use stainless steel tubing - The nut and ferrule are 

       already assembled on the tubing. Slide compression nut onto

       valve inlet and finger tighten compression nut onto valve.

       Tighten another half turn with a wrench; 

DO NOT over 

        tighten. See Figure 29.

5.  With steel clamp and screw, secure water supply line (copper 

tubing only) to rear panel of refrigerator as shown.

6.  Coil excess water supply line (copper tubing only), about 2½ 

turns, behind refrigerator as shown and arrange coils so they 

do not vibrate or wear against any other surface.

7.  Turn ON water supply at shutoff valve and tighten any con-

nections that leak.

8.  Reconnect refrigerator to electrical power source.

9.  To turn ice maker on, lower wire signal arm (freezer ice 

maker) or set the ice maker’s On/Off power switch to the “On” 

position (fresh food ice maker).

• 

Basic Tools: adjustable wrench, flat-blade screwdriver, and 

Phillips™ screwdriver

• 

Access to a household cold water line with water pressure 

between 30 and 100 psi.

• 

A water supply line made of ¼ inch (6.4 mm) OD, copper 

or stainless steel tubing. To determine the length of tubing 

needed, measure the distance from the ice maker inlet valve 

at the back of the refrigerator to your cold water pipe. Then 

add approximately 7 feet (2.1 meters), so the refrigerator can 

be moved out for cleaning (as shown).

• 

A shutoff valve to connect the water supply line to your 

household water system. DO NOT use a self-piercing type 

shutoff valve.

• 

Do not reuse compression fitting or use thread seal tape.

• 

A compression nut and ferrule (sleeve) for connecting a cop-

per water supply line to the ice maker inlet valve.
