Does the size of a high-pressure appliance's refrigerant charge (for example, above versus below 200 pounds) affect which required recovery level applies?
Not quite. The answer is D: Yes — the evacuation table uses the appliance's full charge (under 200 pounds versus 200 pounds or more) as one of the variables that determines which required vacuum level applies
Charge size is a genuine variable in Table 1 of § 82.156. For a high-pressure appliance with newer equipment, a full charge under 200 lb requires 0 in. Hg while 200 lb or more requires 10 in. Hg; medium-pressure appliances are split the same way (10 vs. 15 in. Hg). That is why a technician must check the table for the appliance in front of them rather than relying on one memorized number.
