Legend:
FLA - Full load amperes
ICF - Maximum instantaneous current flow, A (compressors)
kW - Maximum fan motor power input
RLA - Rated load amperes (compressors)
PW - Part-winding astart (compressors)
XL - Across-the-line-start (compressors)
Note: To obtain the maximum unit current, add the compressor maximum currecnt (RLA) to the fan motor current (FLA).
