the shipping brace to the side rails. There will be six
(6) screws on each side of the unit and they are in a
diagonal pattern. See following figure.
3. Lift unit per the “Rigging Details” section of the
installation instructions, observing all warnings and
cautions. Lift the unit high enough off the ground to
reach under and grasp the shipping brace.

falls free from the unit.
