WARNING:

  • Always use HFC-134a for A/C refrigerant. If CFC-12 is accidentally charged, compressor will be damaged due to insufficient lubrication.

  • Do not breathe A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose, or throat.
  • Do not allow HFC-134a to be exposed to an open flame etc. because it generates poisonous gas when in contact with high temperature objects. Keep workshop well ventilated.
