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

Additional Charge
The refrigerant gas is charged in the outdoor unit and, if the piping length is 7.6m, additional charge of the
refrigerant after vacuuming is not necessary.
When the piping length is more than 7.6m, additional refrigerant charge (g) per additional 1m length as
tabulated:
