WARNING:

• Always use HFC-134a for A/C refrigerant. If CFC-12 is accidentally charged, compressor will be damaged due to insufficient lubrication.
• Always observe and follow precautions described on refrigerant container. Incorrect handling may result in an explosion of refrigerant container, frostbite, or the loss of eyesight.
• 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.
