EPA Section 608 Preparatory Manual: Type III

Flashcards covering key concepts from the EPA Section 608 Preparatory Manual regarding refrigerant leak rates, recovery techniques, and regulatory responsibilities.

Maximum leak rate for comfort cooling

10% of the charge per year.

Maximum leak rate for commercial refrigeration

20% of the charge per year.

Maximum leak rate for industrial process refrigeration

30% of the charge per year.

Threshold leak rate for appliances with 50 or more pounds of refrigerant

Owner has 30 days to repair or 18 months to retrofit or retire if exceeding.

Initial verification test

Must be conducted after the repair to ensure leak rates are below the threshold.

Recovery unit cut-out control setting for low-pressure chiller

Typically set for 10 psig.

Average refrigerant remaining in a 350-ton R-123 chiller at 0 psig

Approximately 100 pounds of refrigerant in the vapor state.

Process for evacuation/dehydration involving moisture

Increase pressure with nitrogen to prevent trapped water from freezing.

Record-keeping requirement for leak inspections

Records must be kept for three (3) years.

System mothballing definition

Does not require removing the appliance and storing it.
