or cable slings to the lifting holes provided in the base rails. Spreader
bars, whose length exceeds the largest dimension across the unit,
MUST
be used across the top of the unit.
Units may be moved or lifted with a forklift. Slotted openings in the base
rails are provided for this purpose.

in contact with the unit underside.
CAUTION
All panels must be secured in place when the unit is lifted.
The condenser coils should be protected from rigging cable damage
with plywood or other suitable material.
