EPA 608 Guaranteed Success
1. Definition of Reclaiming:
- To process refrigerant to a level equal to new (virgin) product specifications as determined by
chemical analysis defines: ✔️ Reclaiming.
2. Disposable Cylinder Disposal Method:
- The proper disposal method for disposable cylinders is to ✔️ recover any remaining refrigerant and
then render the cylinder useless, then recycle the metal.
3. Definition of Recycling:
- Clean refrigerant for reuse by separating the oil from the refrigerant by passing it through one or
more filter driers is the definition of: ✔️ Recycle.
4. GWP of R-1234ze:
- The Global Warming Potential (GWP) of R-1234ze is ✔️ 0.
5. Hydrostatic Testing Frequency:
- Reusable refrigerant containers under high pressure must be hydrostatically tested how often? ✔️
Every 5 years.
6. Venting Off Refrigerant Vapor:
- When filling a charging cylinder with a regulated refrigerant, the refrigerant vapor that is vented off
the top must be ✔️ recovered.
7. Example of Non-condensable:
- An example of a non-condensable is ✔️ air.
8. Vacuum System Safety:
- When a system is in deep vacuum, never ✔️ energize the compressor.
, 9. HC Refrigerant for Small Appliances:
- The HC refrigerant allowed for use in new domestic small appliances is ✔️ R-600a.
10. Leak Rate Repair Requirement:
- Leaks must be repaired on industrial process and refrigeration units with a 50-pound charge or
greater when the annualized leak rate reaches ✔️ 30% or more.
11. Refrigerant Trace Gas Release:
- What can be done with a refrigerant trace gas and nitrogen mixture after a system leak is found?
✔️ Release into atmosphere.
12. Classification of Common Refrigerants:
- Refrigerants CFC R-12, HCFC R-22, and HFC 134a are all classified as ✔️ A1.
13. Evacuation Level for R-410A:
- When using a recovery unit on a system containing 100 lbs of R-410A, it must be evacuated to: ✔️
0" Hg.
14. Dehydration Level:
- When dehydrating a system, it should be evacuated to a level of ✔️ 500 microns.

receiver.
16. Action for Non-Repairable Leaking Appliance:
- If a leaking appliance with a regulated refrigerant is not going to be repaired, it must be ✔️
retrofitted or retired within 12 months.
