Before recovering a different refrigerant, which action must technicians perform on the recover/recycle equipment?

Purging is required because when you switch to a different refrigerant, any remaining refrigerant and oil inside the recovery equipment can contaminate the new refrigerant batch. Purging clears those residues from the internal paths and components, ensuring the next refrigerant you recover isn’t tainted and that the equipment operates correctly within regulatory limits. Evacuating would remove refrigerant from the system, but it isn’t the step specifically about preparing the recovery machine for a different refrigerant. Filtering isn’t about removing cross-contamination between different refrigerants, and recovering is the act of removing refrigerant from the system, not the preparation step.
