What is the recommended method for detecting refrigerant leaks in a Class A refrigeration system according to the 2024 IMC?
- AVisual inspection only
- BManual vacuum leak detection with soap solution
- Electronic leak detection equipment
- DLeak detection using ultraviolet light only
Exam tip
Always refer to the latest IMC for specific requirements on refrigeration system maintenance and leak detection.
Why C is correct
The 2024 IMC recommends the use of electronic leak detection equipment for detecting refrigerant leaks in Class A refrigeration systems. Visual inspection and soap solution methods are less reliable and ultraviolet light detection is not as effective for all refrigerants.
