3. When operating the refrigerant, ensure personal protection and avoid contacting or
inhaling the refrigerant.
4. When overhauling the A/C pipe, keep the workspace well ventilated. Don't weld any
A/C pipe containing refrigerant.
5. If disconnected, seal the A/C pipe with a plug and prevent moisture in the air from
entering the system.
6 . Don't directly discharge the refrigerant into the air. Collect it with specialized
equipment and dispose it as required. 41
7. Store the container with refrigerant in a cool area, free of sun exposure and high
temperature, or it may lead to expansion and even explosion.
8. Flammable mixture may occur if the compressed air is blended with the refrigerant.
