According to required recovery levels for Type II appliances before and after November 15, 1993, what is the recovery level for HCFC22 less than 200 lbs after?

The recovery level for HCFC-22 (also known as hydrochlorofluorocarbon 22) in Type II appliances is established to ensure that refrigerants are handled in an environmentally responsible manner. For appliances containing less than 200 lbs of HCFC-22, the required recovery level after November 15, 1993, is indeed 0 psig. This means that technicians are required to capture all of the refrigerant from the appliance until the pressure is reduced to 0 psig, ensuring that there is no emissions into the atmosphere.

This requirement reflects the regulations put in place to mitigate the impact of refrigerants on ozone depletion and climate change. By achieving a recovery level of 0, technicians are ensuring a complete and thorough recovery process, which is critical for compliance with EPA regulations.

The other choices represent levels of recovery that are either too high or irrelevant for this specific guideline, as Type II appliances must achieve a specified low pressure to ensure full recovery of the refrigerant.
