PERFORMANCE DATA
Heating Capacity Tables
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 heating capacity rating obtained with air entering the indoor unit at 70ºF dry bulb (DB) and
60ºF wet bulb (WB), and outdoor ambient conditions of 47ºF dry bulb (DB) and 43ºF wet bulb (WB).
