5.2 Rigging and
Lifting
On each corner, the heavy gauge base of the ventilation unit has a lifting lug with a
1-1/2” diameter hole for rigging. When attaching rigging, insert a clevis in each lifting
lug. Use spreader bars in the rigging. Lift the unit straight up with vertical force.
Test lift the unit to be sure that it is secure. Adjust cables so that the unit will remain
horizontal throughout the lift. Lift slowly, following safe lifting procedures.
Rigging and lifting are the responsibility of the installer.
