EPA Section 608 Universal Certification ExamType I (Small Appliances)Easy
A technician is recovering refrigerant from a small appliance that has a completely evacuated system (0 psig). According to EPA regulations, what is the maximum amount of refrigerant that CANNOT be recovered from this appliance?
- A0 pounds
- B5 pounds
- C1 pound
- D10 pounds
Show answer & explanationAnswer & explanation
Correct answer: A. 0 pounds
If a small appliance system is already completely evacuated (0 psig), it means there is no refrigerant left to recover. Therefore, the maximum amount that cannot be recovered is 0 pounds, as there's nothing to recover.
Why the other options are wrong
- B. This implies there is still refrigerant to be recovered.
- C. This implies there is still refrigerant to be recovered.
- D. This implies there is still refrigerant to be recovered.
Small Appliance No-Recovery Rule (Evacuated System)
If a small appliance system has already been completely evacuated to 0 psig or below, no further refrigerant recovery is required or possible, as there is no refrigerant remaining to be recovered.
- Applies to systems already at 0 psig (or vacuum).
- Indicates the system is empty of refrigerant.
- No 'maximum amount not recovered' exists if there's nothing there.
Memory trick: If the gauge shows 'zero,' your recovery hero has no job to do!
