Nissan Sentra B18 (2020-2025) Service Manual: Recycle Refrigerant
Warning:
-
Always use HFO-1234yf (R-1234yf) for A/C refrigerant. If HFC-134a (R-134a) or CFC-12 (R-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.
-
Do not breathe A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose, or throat.
-
Do not allow HFO-1234yf (R-1234yf) 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.

CAUTION:
Do not perform oil return operation if a large amount of refrigerant or oil leak is detected.
