How do I level the refrigerator and adjust the door height?

Insert a flat-head screwdriver into the slot of the Leveling Leg Control Lever and turn it clockwise to raise the refrigerator or counter-clockwise to lower it. If one door is lower than the other, you can adjust the door height by inserting a Snap Ring (available in 1mm, 1.5mm, 2mm, and 2.5mm sizes) between the door and the hinge. Insert only one Snap Ring at a time, as inserting two or more may cause them to slip out or create a rubbing noise. (Page 15-16)
