Recovery requirements · EPA 608 Type II. The correct answer, and the reasoning behind it.

Evacuation levels by charge size and equipment date, major repairs, and system-dependent limits.

The question

What is the largest full charge on which system-dependent recovery equipment may be used, unless it is a permanently attached pump-out unit?

• A5 pounds
• B50 pounds
• C200 pounds
• D15 poundsCorrect answer

Why “15 pounds” is correct

System-dependent equipment relies on the appliance's own compressor or pressure. It may not be used on appliances with a full charge of more than 15 pounds unless it is permanently attached as a pump-out unit.

Why the other answers are wrong

• 5 pounds — 5 pounds is the small-appliance limit, not the system-dependent limit.
• 50 pounds — 50 pounds is the leak repair threshold under Part 82.
• 200 pounds — 200 pounds splits rows of Table 1; it is not the system-dependent limit.
