Maximum Heating Capacity Table for LC489HHV (LCN489HV + LUU480HHV)
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.
3. Grey shading indicates reference data. When operating at this temperature, these values can be
different if the system is not running consistently.
Capacity as rated: 0 ft. above sea level with 24.6 ft. of refrigerant piping. 0 ft. level difference between
outdoor and indoor units.
Maximum capacity based on full-load (maximum) compressor operation rather than part-load operation
as published in rated capacity tables.
