5.9 LEAK TESTING
A leak can be identified by the presence of oil
residue on the components.
The preferred method for leak testing is to
replace refrigerant with pressurized nitrogen and
spaying soap on suspected leaks. Any bubbles
appearing would indicate a leak.
Additional possible methods include electronic
leak detectors and fluorescent dye and UV light.
