Preparing to install the refrigerator.
Read these instructions completely and carefully.
Rollers
The rollers have 3 purposes:
Rollers adjust so the door closes easily when opened about halfway.
1
[Raise the front about 5/8" (15 mm) from the floor.]
To assure that the doors will close automatically from a halfway open position,
there is a built-in tilt from the front to the back of the cabinet. Side-by-side
refrigerators also have specially designed door hinges that lift both doors slightly
when opened, allowing the force of gravity to help close them securely.
Rollers adjust so the refrigerator is firmly positioned on the floor
2
and does not wobble.
Rollers allow you to move the refrigerator away from the wall for cleaning.
3
To adjust the rollers, remove the base grille by pulling it out at the bottom.
Turn the roller adjusting screws clockwise to raise the refrigerator,
counterclockwise to lower it. Use an adjustable wrench (3/8" hex head bolt)
or pliers.
To replace base grille, align prongs on back of grille with clamps in cabinet and
push forward until grille snaps into place.
