PERFORMANCE DATA
Cooling Capacity Tables
TC = Total Capacity (kBtu/h).
PI = Power Input (kW).
Nominal capacity as rated: 0 ft. above sea level with 25 ft. of refrigerant piping.
0 ft. level difference between outdoor and indoor units.
Nominal cooling capacity rating obtained with air entering the indoor unit at 80ºF dry bulb (DB) and
67ºF wet bulb (WB), and outdoor ambient conditions of 95ºF dry bulb (DB) and 75ºF wet bulb (WB).
The shaded rows indicate reference data. When operating at this temperature, these values can be
different if the system is not running consistently.
