After recovering refrigerant, what information must be recorded on the recovery cylinder?
Answer: Refrigerant type, amount recovered, and date
Recovery cylinders must be labeled with the refrigerant type and amount to prevent mixing refrigerants and ensure proper handling during reclamation.
What happens to recovered refrigerant that is too contaminated to be reused in the same system?
Answer: It must be sent to an EPA-certified reclamation facility
Heavily contaminated refrigerant must be sent to an EPA-certified reclamation facility where it is processed to ARI-700 purity standards before being resold.
What is 'system-dependent' (passive) recovery?
Answer: Using the refrigeration system's own compressor to transfer refrigerant to a recovery cylinder
System-dependent recovery uses the refrigeration system's own compressor to pump refrigerant vapor into a recovery cylinder, and is only permitted on small appliances.
What does it mean when a recovery machine 'cycles off on low pressure' during the recovery process?
Answer: The refrigerant recovery is substantially complete for that section of the system
When a recovery machine cycles off on low pressure, it indicates that the refrigerant vapor pressure has dropped low enough that most accessible refrigerant has been removed.
Which EPA regulation section specifically governs refrigerant recovery and recycling requirements for stationary refrigeration and air conditioning equipment?
Answer: Section 608
EPA Section 608 of the Clean Air Act establishes the requirements for refrigerant recovery, recycling, reclamation, and technician certification for stationary equipment.
When must a technician achieve the EPA's required recovery efficiency before opening a system?
Answer: Before opening any part of a system that contains a regulated refrigerant
EPA regulations require achieving the specified recovery efficiency before opening any refrigeration or AC system containing a regulated refrigerant, regardless of circumstances.
