🛠️ Application Method
- Ensure your HVAC system is specifically designed for R-32 refrigerant.
- Wear appropriate PPE and work in a well-ventilated area due to mild flammability (A2L rating).
- Connect your charging hose to the cylinder’s left-hand threaded valve using a compatible adapter if needed.
- Charge the system carefully according to the manufacturer's specifications and pressure guidelines.
- Once finished, tightly close the valve and store the cylinder upright in a cool, dry location.
⚠️ Warning: R-32 is not a retrofit gas. Use only with systems that are approved and labeled for R-32. Improper use may result in damage or hazards.
