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).
Cooling range with Low Ambient Wind Baffle Kit (sold separately) is -4°F to +118°F.
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.
Due to our policy of continuous product innovation, some specications may change without notication.
