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

Notes:
1. Equivalent piping length is obtained with actual length of gas piping.
2. 90° bend of piping is equivalent to L joint.
Bending must be carefully made so as not to crush the pipe.
Use a pipe bender to bend a pipe where possible.
* Spec with accumulator is available for 50m piping length application.
** Max. Allowance Length = Straight pipe length + Equivalent bends straight length
*** NOT applicable to modular coupling system.
Our guarantee on the performance of our air-conditioners is strictly revoked if the height
and/or length of the refrigerant piping system installed is beyond the limit above.
