What is the first step in the safe recovery of refrigerants?

The first step in the safe recovery of refrigerants is connecting the recovery machine to the system properly. This step is critical because it ensures that the recovery process can begin in a controlled and efficient manner. Proper connection of the recovery machine is essential to prevent leaks and ensure that the refrigerant is collected safely. When a recovery machine is correctly attached, it allows for the refrigerant to be drawn out of the system effectively while minimizing the risk of exposure to harmful substances.

Additionally, following best practices for this connection can also help avoid contamination of the refrigerant and ensure that it is collected in a manner that complies with safety and environmental regulations. Proper training on handling these connections also helps technicians be aware of any potential hazards associated with refrigerant recovery.

The other steps mentioned are necessary in the overall process of refrigerant recovery but are secondary to establishing the correct connections first. For instance, disconnecting the power supply is necessary for safety, but if the recovery machine is not set up properly, the recovery cannot proceed effectively.
