6.1.3 Note on adding refrigerant

Some systems require additional charging
depending on pipe lengths. The standard pipe
length varies according to local regulations. For
example, in North America, the standard pipe

length is 7.5m (25'). In other areas, the standard
pipe length is 5m (16'). The refrigerant should be
charged from the service port on the outdoor unit's
low pressure valve. The additional refrigerant to
be charged can be calculated using the following
formula:
