A superintendent pulls twenty window air conditioners out of the walls every October, stores them in a basement, and reinstalls the same units the following May. What do the recovery rules require at the time the units are removed?
Correct Answer
D) No recovery, because no circuit is being opened and no unit is being disposed of
Recovery is triggered by opening a sealed refrigerant circuit or by disposing of the appliance. Unplugging a window unit, lifting it out of a wall sleeve and setting it on a shelf does neither. The charge stays where it has always been, inside a circuit that nobody has touched. Nothing changes if the unit sits for six months or six years, and nothing changes when it goes back in. The obligation would appear only if one of those units were later scrapped, or if a technician opened its circuit to make a repair.
Why This Is the Correct Answer
The recovery requirement attaches to two events, opening the sealed circuit and disposing of the appliance, and seasonal removal and storage is neither. The refrigerant remains contained in an intact circuit throughout, which is exactly the outcome the regulation is designed to produce. Handling, transporting and storing a charged appliance are ordinary activities that create no recovery duty on their own.
Why the Other Options Are Wrong
Option A: Recovery from each unit, because removing an appliance from service triggers the requirement
Taking an appliance out of service is not one of the triggers. Equipment sits idle in storage all over the country with its charge intact and that is entirely lawful.
Option B: Recovery from each unit, because storage counts as disposal until the unit goes back in
Storage is not disposal. Disposal means the appliance is being discarded or sent for destruction, not set aside for reuse next season.
Option C: Recovery from any unit older than the shop's recovery machine, and none from the rest
The recovery machine's build date decides what level a recovery must reach. It has nothing to do with whether a recovery is required in the first place.
Memory Technique
Open it or ditch it. Anything else, the charge stays put.
Reference Hint
Recovery is required when the sealed circuit is opened or when the appliance is disposed of. Storing or moving a charged unit is neither.
