Application Information
Refrigerant Piping
Piping Length and Elevation
If the pipe is too long, both the capacity and reliability of the unit will drop. As the number of bends increases,
resistance to the
fl
ow of refrigerant system increases, thus lowering cooling capacity. As a result, the
compressor may become defective. Always choose the shortest path and follow the recommendations as
tabulated below:

* Be sure to add the proper amount of additional refrigerant. Failure to do so may result in reduced performance.
Remark: The refrigerant pre-charged in the outdoor unit is for piping length up to 7.5m.
