Recycle Refrigerant INFOID:0000000011006107 WARNING: • Always use HFC-134a for A/C refrigerant. If CFC-12 is accidentally charged, compressor is 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. • Never breathe A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose, or throat. • Never allow HFC-134a to be exposed to an open flame or others because it generates poisonous gas when in contact with high temperature objects. Keep workshop well ventilated. 1. Perform lubricant return operation. Refer to HA-113, "Perform Lubricant Return Operation" . (If refrigerant or lubricant leakage is detected in a large amount, omit this step, and then GO TO 2.)
