What must happen to the non-leaking components that will be opened?

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

A 220-pound R-22 system has a badly leaking evaporator. The technician can isolate the evaporator from the rest of the system. What must happen to the non-leaking components that will be opened?

• AThey may be opened at 0 psig like the leaking part
• BThey need no evacuation if they are isolated
• CThey must be evacuated to the Table 1 levelCorrect answer
• DThey may be opened once liquid is removed

Why “They must be evacuated to the Table 1 level” is correct

The leaky-appliance exception covers only the leaking parts. The technician must isolate leaking from non-leaking components where possible and evacuate the non-leaking components to the full Table 1 levels.

Why the other answers are wrong

• They may be opened at 0 psig like the leaking part — The 0 psig ceiling applies only to the leaking components.
• They need no evacuation if they are isolated — Isolation does not excuse non-leaking components that are being opened from evacuation.
• They may be opened once liquid is removed — Removing the liquid is not enough; the components must reach the Table 1 vacuum level.
