COOLING CAPACITY DATA
144,000 Btu/h 208-230V / 460V Outdoor Units
ARUM144BTE5 / ARUM144DTE5
TC = Total Capacity (MBh). PI = Power Input (kW) (includes compressor and outdoor fan).
Cooling range with the Low Ambient Baffle Kit (sold separately) is -9.9°F to +122°F and is achieved
only when all indoor units are operating in cooling mode. Does not impact heat recovery system
synchronous operating range.
The System Combination Ratio must be between 50–130%.
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).
