PERFORMANCE DATA
Cooling Capacity Tables
DB: Dry Bulb Temperature (°F) WB: Wet Bulb Temperature (°F) TC: Total Capacity
(kBtu/h)
SHC: Sensible 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. Cooling operating range with the Low Ambient Baffle Kit (sold separately) is -4°F to
+122°F.
3. Grey shading indicates reference data. When operating the unit at this temperature,
these values can be different by discontinuous operation.
4. 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 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).
