Before opening any MVAC system for repairs, what must a technician do first?
Answer: Recover all refrigerant using approved equipment
EPA regulations require that all refrigerant must be recovered using approved recovery equipment before any MVAC system component is opened.
Recovery equipment for MVAC systems must be certified to which standard?
Answer: SAE J2788
MVAC refrigerant recovery/recycling equipment must meet SAE J2788 standards, which specify recovery and purity efficiency requirements.
What is the difference between 'recovery' and 'recycling' of refrigerant?
Answer: Recovery removes refrigerant from the system; recycling cleans it on-site for reuse
Recovery transfers refrigerant from the vehicle to a container, while recycling additionally passes it through filters and driers to remove contaminants for reuse.
What is 'reclaimed' refrigerant?
Answer: Refrigerant sent to a certified facility and processed to meet AHRI 700 purity standards
Reclaimed refrigerant has been processed off-site to meet AHRI 700 purity standards, equivalent to virgin refrigerant.
Recovered refrigerant that is contaminated with moisture or other refrigerants should be:
Answer: Sent to a certified reclaimer for processing
Contaminated refrigerant must be sent to a certified reclaimer who has equipment to separate and purify it properly.
According to EPA Section 609, recovery equipment must remove what percentage of refrigerant from an MVAC system?
Answer: At least 90%
EPA-approved MVAC recovery equipment must achieve at least 90% efficiency in removing refrigerant from the system.
