Refrigerant adjustment: lf total pipe length exceeds P, additional refrigerant (R32) charge is
required. (The outdoor unit is charged with refrigerant for total pipe length up to P meters).
Pipe length
≤P m
No additional charge required
>P m
An additional charge required:
20 g/m x (refrigerant piping length (m) - P)
