B.2.4 Cabinet Leveling
I. Locating the cabinet
Move the cabinet to the planned location with its feet aligned with the corresponding
foot location marks.
II. Leveling the cabinet
Place a horizontal ruler in two orthogonal directions on top of the cabinet to check the
cabinet levelness. If the cabinet is not leveled, loosen the retaining nuts on the cabinet
feet with a wrench and turn the cabinet foot finely to adjust the cabinet height to make it
leveled. Meanwhile, align all of the cabinets, and then lock the retaining nuts on the
cabinet feet until they are pressed tightly against the bottom plane of the cabinet.
