Table 73:
LMU36CHV Cooling Capacity Table — Non-Ducted Indoor Units (continued).
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 table rows indicate reference data. When operating at this temperature, these values can
be different if the system is not running consistently.
