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.

1. Perform oil return operation. Refer to HA "Perform Oil Return Operation". (If refrigerant or oil leakage is detected in a large amount, omit this step, and then GO TO 2.) CAUTION: Do not perform oil return operation if a large amount of refrigerant or oil leakage is detected.
