REFRIGERANT PIPING
Piping Length & Elevation
If the pipe is too long, both 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 not exceed the maximum piping
length as tabulated below.
