A building owner is relocating a working R-123 chiller to another property that the same owner controls. What has to happen to the charge before the machine is disconnected?
Correct Answer
B) It has to be recovered to the required level before the refrigerant circuit is broken
Breaking into the refrigerant circuit is what triggers the requirement, and disconnecting a chiller for a move means opening it. The charge comes out to the required level with certified recovery equipment, goes into labeled cylinders, and travels separately. Ownership is irrelevant here: the same owner on both ends changes nothing about opening the machine. It does help later, since a charge going back into the appliance it came from needs no reclamation.
Why This Is the Correct Answer
The evacuation requirement attaches to opening the appliance for service, maintenance, repair or disposal, and taking a machine apart to move it opens it. Recovery to the required level with certified equipment comes first, and the cylinders are labeled and transported separately. The charge may go back into the same machine at the new site without reclamation.
Why the Other Options Are Wrong
Option A: Nothing, because the machine is staying with the same owner and is not being disposed of
Continuing ownership matters for what may be done with the refrigerant afterward, not for whether the circuit may be opened while full.
Option C: It has to be transferred into the machine's condenser and the isolation valves wired shut
Isolation valves are not a substitute for recovery when the machine is being taken apart, and vessels full of refrigerant should not be shipped as part of a machine.
Option D: It has to be sent to a reclaimer, because a charge cannot be moved between two properties
Reclamation is not required for a charge returning to the appliance it came from, and refrigerant moves between sites in cylinders every day.
Memory Technique
If it comes apart, the charge comes out first. Who owns it decides only where it goes next.
Reference Hint
Appliances must be evacuated to the required level before the refrigerant circuit is opened, including for relocation.
