Application Information
(4) Refrigerant Piping
Maximum Pipe and Maximum Number of Bends
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 font compressor may become defective. Always choose the shortest path and follow
the recommendation as tabulated below:
