HA-20 < PERIODIC MAINTENANCE > ELECTRICAL LEAK DETECTOR ELECTRICAL LEAK DETECTOR Checking of Refrigerant Leaks INFOID:0000000009478585 Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C oil leak- age, damage, and corrosion. Any A/C oil leakage may indicate an area of refrigerant leakage. Allow extra inspection time in these areas when using either an electronic refrigerant leak detector (J-41995) or fluores- cent dye leak detector (J-42220). If any dye is observed using a fluorescent dye leak detector (J-42220), confirm the leak using a electronic refrigerant leak detector (J-41995). It is possible that the dye is from a prior leak that was repaired and not properly cleaned. When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all system components and connections. When searching for refrigerant leaks using an electronic refrigerant leak detector (J-41995), move the probe along the suspected leak area at 25 - 50 mm (1 - 2 in) per second and no further than 6 mm (1/4 in) from the component. CAUTION: Moving the electronic refrigerant leak detector probe slower and closer to the suspected leak area will improve the chances of finding a leak. Electronic Refrigerant Leak Detector INFOID:0000000009478586 PRECAUTIONS FOR HANDLING LEAK DETECTOR NOTE: When performing a refrigerant leak check, use a electronic refrigerant leak detector (J-41995) or equivalent. Ensure that the electronic refrigerant leak detector (J-41995) is calibrated and set properly according to the manufacturer's operating instructions. The electronic refrigerant leak detector (J-41995) is a delicate device. To use the electronic refrigerant leak detector (J-41995) properly, read the manufacturer's operating instructions and perform any specified maintenance. 1. Position the probe approximately 5 mm (3/16 in) away from the point to be checked as shown. AHA281A SHA707EA |
