Application Information

(4) Refrigerant Piping

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:
