1. Standard length of connection pipe
● 15ft, 22.5ft,24ft
4. Additional refrigerant may be required when extending the line-set.
● After the line-set has been extended 33ft past standard length of 25ft,
adding additional 5ml of refrigerant oil for each additional 16ft.
● The calculation method of additional refrigerant charging amount (on the basis
of liquid pipe):
● Basing on the length of standard pipe, add refrigerant according to the
Additional refrigerant charge amount = extended length of liquid line x
required additional amount per foot.
2.Min. length of connection pipe is 9Ft .
