1. All capacities are net, evaporator fan motor heat is deducted.
2. Grey shading indicates reference data. When operating at this temperature, these values can be
different if the system is not running consistently..
3. Direct interpolation is permissible.
Do not extrapolate.
Capacity as rated: 0 ft. above sea level with 24.6 ft. of refrigerant piping. 0 ft. level difference between
outdoor and indoor units.
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).
