the base frame corners.
• Lifting cables should be attached to the unit with
shackles.
• The distance between the crane hook and the top of
the unit must not be less than 60”.
• Two spreader bars must span over the unit to prevent
damage to the cabinet by the lift cables. Spreader
bars must be of sufficient length so that cables do not
come in contact with the unit during transport.
Remove wood struts mounted beneath unit base
frame before setting unit on roof curb. These struts
are intended to protect unit base frame from fork lift
damage. Removal is accomplished by extracting the
sheet metal retainers and pulling the struts through
the base of the unit. Refer to rigging label on the unit.

work should be attached to the curb prior to installing the
unit. Ductwork dimensions are shown in Roof Curb Installa-
tion Instructions.
Refer to the Roof Curb Installation Instructions for proper curb
installation. Curbing must be installed in compliance with the
National Roofing Contractors Association Manual.
