WARNING
• Unit must be lifted by the four lifting holes located at 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.
Important:
If using bottom discharge with roof curb, ductwork
should be attached to the curb prior to installing the unit. Ductwork
dimensions are shown in Roof Curb Installation Instructions.
Refer to the Roof Curb Installation Instructions for proper curb
installation. Curbing must be installed in compliance with the Na-
tional Roofing Contractors Association Manual.
Lower unit carefully onto roof mounting curb. While rigging unit,
center of gravity will cause condenser end to be lower than supply
air end.
