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
Do not lift units two at a time. Provisions
for forks have been included in the unit base
frame. Minimum fork length is 72” to prevent
damage to the unit.
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.
• Your unit may be equipped with a steel shipping brace
located underneath the unit (under compressors). If
installing on a roof curb, the brace MUST be removed.
Follow the following instructions for removal.
CAUTION
When unit is suspended, boards and shipping
brace will drop when screws are removed. To
prevent personal injury, STAND CLEAR. Remove
fork hole brackets, boards and shipping brace
from bottom of unit before placing unit onto
curb.
Before installing this unit on a roof curb:
1. Remove wooden struts per installation instructions.
These are the struts that are located in the fork holes
and are used to protect the unit from damage while
lifting with forks.
2. Locate and remove the four (4) screws that attach the
shipping brace to the side rails. There will be two (2)
screws on each side of the unit.
See following figure
.
3. Lift unit per the “Rigging Details” section of the
installation instructions, observing all warnings and
cautions. Lift the unit high enough off the ground to
reach under and grasp the shipping brace.
4. Rotate the brace by tapping the ends until the brace
falls free from the unit.
5. Dispose of the brace appropriately.
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.
