  • Page 17 Application Information 4) Refrigerant Piping Maximum Piping Length 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 compressor may become defective.
  • Page 18 Application Information 5) Additional Charge • The refrigerant charge has already charged into the outdoor unit. For the piping length of 7.6m, additional refrigerant charge after vacuuming is not necessary. • When the piping length is more than 7.6m, please use the table below (unit in gram).
