  Caution

  • If moisture or foreign material enters the refrigeration cycle, cooling ability will be lowered and abnormal noise will occur. Always immediately plug all open fittings after removing any refrigeration cycle parts to keep moisture or foreign material out of the cycle.
  • Do not allow A/C compressor oil to spill. Operating the A/C compressor without sufficient A/C compressor oil can lead to abnormal noise and cause the A/C compressor to seize up.
