Before recovering refrigerant, what must the technician do?

Identifying the refrigerant before recovering it is crucial for several reasons. Different refrigerants have distinct properties, pressures, and recovery methods. Using the wrong method for a particular type of refrigerant can lead to system damage, safety hazards, or environmental harm.

Knowing the specific refrigerant allows technicians to apply the appropriate recovery techniques and equipment, ensuring compliance with safety regulations and environmental guidelines. Furthermore, refrigerants are regulated due to their potential impact on the ozone layer and global warming; identifying the refrigerant helps in adhering to proper disposal procedures.

By accurately determining the refrigerant type, a technician ensures that the recovery process is safe, efficient, and compliant with industry standards.
