Rigging the Unit for Lifting
Rig the unit for lifting by attaching four cables to the holes in
the base rail of the unit as illustrated in figure 5.
1. Remove protective packaging before rigging the unit
for lifting.
2. Connect the rigging to the holes in each corner of the
unit's base.
3. All panels must be in place for rigging.
4. Place a field‐provided H‐style frame just above the
top edge of the unit. The frame must be of adequate
strength and length. (An H‐style frame will prevent
the top of the unit from being damaged.)
