Correct answer
Removing refrigerant from a system and storing it in an external container
Why
Recovery is removing refrigerant from a system and storing it in an external container without necessarily testing or processing it.
The concept behind this question
Recover, recycle and reclaim are three distinct things and the exam tests whether you know the difference. Recovering means removing refrigerant from an appliance and storing it, with no processing. Recycling means cleaning it for reuse — typically oil separation and a filter-drier pass — usually on site. Reclaiming means reprocessing it to meet the AHRI 700 purity specification, which requires laboratory analysis and can only be done by a certified reclaimer, not in the field.
