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:
ADDITIONAL REFRIGERANT PER PIPE LENGTH
Connective Pipe
Purging
Length (m)
Method
≤ Standard pipe Vacuum

>Standard pipe Vacuum
length
For R290 refrigerant unit, the total amount of refrigerant to be charged is no more than:
387g (<=9000Btu/h), 447g (>9000Btu/h and <=12000Btu/h), 547g (>12000Btu/h and
<=18000Btu/h), 632g (>18000Btu/h and <=24000Btu/h).
CAUTION DO NOT mix refrigerant types.
