Note on Adding Refrigerant
Some systems require additional charging depending on pipe lengths. In North America, the
standard pipe length is 15' (7.5 meters). 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.
Connective Pipe
Length (m)
≤ Standard pipe length
> Standard pipe length
CAUTION: DO NOT mix refrigerant types.
