WARNING
T
O 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 dam-
age 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 mount-
ed 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.
Lower unit carefully onto roof mounting curb. While rigging
unit, center of gravity will cause condenser end to be lower
than supply air end.
