A rack whose nameplate lists a full charge of two hundred forty pounds has leaked down and now holds only about one hundred thirty pounds. Which figure decides whether the two hundred pound line of the evacuation table applies?
Correct Answer
A) The full charge the appliance normally holds when correctly charged
The evacuation table is written around what an appliance normally contains, which means its full and correct charge rather than whatever happens to be in it when the technician arrives. A rack rated for two hundred forty pounds stays on the two hundred pound or more row even after it has leaked down to half that. Judging by the current contents would let a leaking appliance, the one most likely to release refrigerant, drop to an easier standard than a tight one.
Why This Is the Correct Answer
Normal charge means the full charge the appliance is designed to hold, which is read off the nameplate or the manufacturer's data. It does not change when the appliance leaks down, and it does not change when a technician has already pulled part of the charge out. A rack rated at two hundred forty pounds is a two hundred pound or more appliance on every service call for its whole life.
Why the Other Options Are Wrong
Option B: The amount of refrigerant actually in the appliance on the service day
Using the day's actual contents would move an appliance between rows every time it leaked, and would reward the leakiest equipment with the shallowest requirement.
Option C: The amount of refrigerant the recovery cylinder is able to accept
Cylinder capacity is a job planning question. Nothing in the evacuation table is written around how much the technician's cylinder can hold.
Option D: The combined charge of every appliance the owner has on the property
Charges are never added across separate appliances for this purpose. Each appliance is placed on the table by its own normal charge.
Memory Technique
Nameplate, not needle. What the machine is supposed to hold sets the rule, not what is left in it.
Reference Hint
The two hundred pound split in the evacuation table is measured against the appliance's full, normal charge.
