TC = Total Capacity (kBtu/h).
PI = Power Input (kW).
Nominal capacity as rated: 0 ft. above sea level with Piping Length as Main Pipe (16.4 ft.) + Branch
pipe (98.4 ft.) = 115 ft.
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 table columns and rows indicate reference data. When operating at this temperature, these
values can be different if the system is not running consistently.
