PERFORMANCE DATA
Heating Capacity Tables
DB: Dry Bulb Temperature (°F) WB: Wet Bulb Temperature (°F) TC: Total
Capacity (kBtu/h)
PI: Power Input (kW) (includes compressor, indoor fan motor, and outdoor
fan motor)
1. All capacities are net, evaporator fan motor heat is deducted.
2. Direct interpolation is permissible.
Do not extrapolate.
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 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).
