Some systems require additional charging depending on pipe lengths. The standard pipe length
is 10m. The additional refrigerant to be charged can be calculated using the following formula:
Make sure to remove the additional refrigerant charge according to the rated volume (5m
refrigerant piping) when doing market or government verication test.
