Storing the container of recycled refrigerant at a temperature above 65°F (18°C) for 12 hours allows sufficient time for non-condensable gases, such as air, to separate from the refrigerant. The separation process occurs because non-condensable gases do not condense under these conditions and will remain in vapor form. By allowing the refrigerant to sit for this duration, technicians can ensure that the refrigerant is primarily composed of the intended substances, free from contamination that could affect the air conditioning system's performance.

This prolonged storage time helps in accurately assessing the purity of the refrigerant before its use in the vehicle's air conditioning system. If the container were stored for a shorter period, there may not be enough time for the non-condensable gases to fully rise to the top or separate from the liquid refrigerant, potentially leading to issues when the refrigerant is reintroduced into the A/C system.
