RIGGING DETAILS
To prevent property damage, the unit should remain in an
upright position during all rigging and moving operations. To
facilitate lifting and moving when a crane is used, place the
unit in an adequate cable sling.
If units are lifted two at a time, the fork holes on the
condenser end of the unit must not be used. Minimum fork
length is 42" to prevent damage to the unit; however, 48" is
recommended.
Provisions for forks have been included in the
unit base frame. No other fork locations are
approved.
To prevent possible equipment damage, property damage,
personal injury or death, the following bullet points must
be observed when installing the unit.
• 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.

WARNING
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 National Roofing Contractors Association Manual.
