Refrigerant Leakages
REFRIGERATION SYSTEM
Refrigerant Leakages
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant leakage, damage and corrosion. A/C lubricant leakage may indicate an area of refrigerant leakage. Allow extra inspection time in these areas when using either an electrical leak detector or fluorescent dye leak detector (SST: J-42220).
Confirm the leakage with an electrical leak detector if dye is observed. It is possible a prior leakage was repaired and not properly cleaned.
If a leakage is found but continue checking for additional leakages at all system components and connections when searching for leakages.
Move the probe along the suspected leakage area at 1 to 2 inches per second and no further than 1/4 inch from the component when searching for refrigerant leakages using an electrical leak detector.
CAUTION:
Moving the electrical leak detector probe slower and closer to the suspected leakage area improves the chances of finding a leakage.
