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.
