Never breathe A/C refrigerant and lubricant vapor or mist. Exposure my irritate eyes, nose, or throat.
Never allow HFO-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.
Use a approved refrigerant recovery/recycling equipment (for HFO-1234yf).
Connect recovery/recycling/recharging equipment to the A/C service valve.
Operate recovery/recycling/recharging equipment, and evacuate air from A/C system for 25 minutes or more.
