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).

Tighten down loose lines, mark leaks. 

Then draw off draw off A/C system and seal off or repair leakage
points.

Then refill A/C system and test for leaks.
