Which of the following statements regarding pump down or removal of refrigeration is false?

The statement that refrigerant removal requires bringing the system into high-pressure to evaporate the refrigerant from the section being dismantled is incorrect. In fact, the process of removing refrigerant generally involves first shutting down the refrigeration system and creating a low-pressure environment to safely extract the refrigerant. This typically involves using a recovery machine that operates under a vacuum, allowing for the refrigerant to be collected without needing to introduce high pressure.

Additionally, introducing high pressure for the purpose of refrigerant removal is not standard practice as it can lead to hazards, including potential damage to the system or even personal injury. The preferred method is to utilize a vacuum pump to create a low-pressure environment that can effectively pull the refrigerant out of the system. Understanding these principles is critical for ensuring safety and compliance with refrigeration regulations.
