Type II — medium, high and very high-pressure appliancesDifficulty 3/5
System-dependent recovery equipment may not be used on an appliance containing more than how much refrigerant?
- ATwo hundred pounds, above which the evacuation requirement in Table 1 increases
- BFifteen pounds, above which self-contained recovery equipment must be used instead
- CFive pounds, above which the appliance ceases to be classed as a small appliance
- DFifty pounds, above which the appliance becomes subject to the leak repair rules
Show answer and rationale
Correct: B. Fifteen pounds is the cut-off for passive, system-dependent recovery. It is easy to confuse with the other thresholds in the rule, which is exactly why the exam includes all of them as options.
- C — Five pounds is the small-appliance definition threshold, not the recovery equipment limit.
- D — Fifty pounds is the charge at which the 82.157 leak repair requirements begin to apply.
- A — Two hundred pounds is a Table 1 breakpoint for evacuation levels, not an equipment limit.
