RIGGING DETAILS
WARNING
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.
CAUTION
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.
WARNING
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. 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.
