RFI7: Regarding the rigging for the Rooftop unit, going to the top of an elevator shaft. Can the unit, which weighs 2300 lbs, Length 7’7”, Width 4’9”, Height 8’1” be moved through existing openings in the building and utilizing freight elevators to the desired location on the roof, or will it require an external rig to put the unit on the roof?

He may have to disassemble the units into smaller pieces to carry in and reassemble in field. An exterior rig should not be required.
