NOTE: The weight distribution and center of gravity information include the impact of an economizer, the largest indoor fan motor, and a VFD (variable frequency
drive). On units with a return fan or high-capacity power exhaust, the largest motors and VFD are also included. These weights do not include the impact of other
factory-installed options such as barometric relief, power exhaust, high-capacity indoor coil, hot water coil, or indoor fan.
