All capacity class
The length intended for the capacity calculation, which counts the length of refrigerant piping and
the number of bends, is called actual length.
Length of refrigerant piping (ft.) + ( Number of bends × 0.984 ft. ) = Actual length of refrigerant piping (ft.)
[Length of refrigerant piping (m) + ( Number of bends × 0.3 m ) = Actual length of refrigerant piping (m)]
