Necessary preliminary tasks:
Carry out leak-testing with a leak tester device from the workshop equipment catalogue following the device manufacturer's operating instructions.
If leaks not to be localized are already identified during evacuation, the A/C system must nevertheless be filled. Then test for leaks with leak tester device.
NOTE:
Refrigerant is heavier than air.
Therefore always conduct the leak test below the lines and components to be tested.
Shield lines and components against strong blasts of air (wind, drawing off).
