4) Refrigerant Piping
When the pipe length becomes too long, both the capacity and reliability drop. As the number of bends
increase,resistanceto owofrefrigerantsystem increases,thusloweringcoolingcapacityandasaresult
the compressor may become defective. Always choose the shortest path and follow the recommendation as
