Detecting Leaks
In this lesson, you’ll learn about how refrigerants should be handled so you to abide by the law and take care of the environment.
In this lesson, you’ll know how to store and safely handle cylinders, how to prevent incidents from happening, and what to expect and do if they should occur.
In this lesson, you will learn how to check for leaks and detect them, perform a pump-down and recover the refrigerant that is still left in the system.
In three steps, this lesson focuses on how to change cooler oil, and you will learn how to drain the oil and see the importance of the dryer and sight glass.
In this lesson, you will learn how to finish the reefer maintenance, by vacuum pumping the system for moisture, topping up the oil and adding new refrigerant.

Here follows a video about how to detect leaks and where you primarily should focus on the leakage search. Before conducting a leak check, test your instrument on a reference leak to ensure that the device is working correctly. When searching for leaks, there are certain things you should pay special attention to:
When you search for leaks, turn off the compressor to allow the low-pressure side to equalise with the high-pressure side. If the refrigerant is disappearing without a trace, the condenser is likely leaking.
