EPA Section 608 Universal Certification ExamCoreHard
A technician is performing a leak test on a low-pressure chiller operating with R-123. If the system is found to be leaking, what is the maximum amount of time allowed to repair the leak and verify the repair before EPA regulations require the appliance to be retrofitted or retired?
- A120 days
- B10 days
- C90 days
- D30 days
Show answer & explanationAnswer & explanation
Correct answer: D. 30 days
For comfort cooling appliances with a charge of 50 lbs or more, the EPA requires leaks to be repaired within 30 days of detection. If the leak rate exceeds the threshold (10% for comfort cooling), the owner must repair the leak and conduct follow-up verification tests. If the leak cannot be repaired within 30 days, an extension can be granted, but the general rule is 30 days.
Why the other options are wrong
- A. 120 days is not a standard repair timeframe under Section 608 regulations.
- B. 10 days is typically for industrial process refrigeration or when an extension is denied, not the initial repair period.
- C. 90 days is a possible extension period if certain conditions are met, but not the initial repair window.
EPA Leak Repair Timeframes
EPA Section 608 regulations specify maximum timeframes for repairing leaks in appliances with 50 lbs or more of refrigerant, based on the appliance type.
- Comfort Cooling and Commercial Refrigeration: 30 days.
- Industrial Process Refrigeration: 30 days (or 120 days for certain conditions).
- Verification tests required after repair.
- Extensions (e.g., 120 days) are possible under specific circumstances.
Memory trick: 30 days for comfort, no more delays, or the system's fate sealed always.
