Warranty and Liability

Special Information for Automotive Technicians

JB’s LD-2500 HUNTER Refrigerant Leak Detector is design certifi ed by
MET Laboratories, Inc. to meet SAE J1627, “Rating Criteria for Electronic
Refrigerant Leak Detectors” for R12, R22, R134a. The following SAE Rec-
ommended Practice applies to this instrument and to the use of generally
available electronic leak detection methods to service motor vehicle pas-
senger compartment air conditioning systems.


The electronic leak detector shall be operated in accordance with the equipment manu-
facturer’s operating instructions.


Leak test with the engine not in operation.


The A/C system shall be charged with suffi cient refrigerant to have a gauge pressure of
at least 50 PSI (340 kPA) when not in operation. At temperatures below 59̊ F (15̊ C)
leaks may not be measurable, since this pressure may not be reached.

4. Take care not to contaminate the detector probe tip if the part being tested is contami-

nated. If the part is particularly dirty, it should be wiped off with a dry shop towel or
blown off with shop air. No cleaners or solvents shall be used, since many electronic
detectors are sensitive to their ingredients.

5. Visually trace the entire refrigerant system, and look for signs of air conditioning lu-

bricant leakage, damage, and corrosion on all lines, hoses, and components. Each
questionable areas shall be carefully checked with the detector probe as well as all
fi ttings, hose-to-line couplings, refrigerant controls, service ports with caps in place,
brazed or welded areas, and areas around attachment points and hold-downs on lines
and components.

6. Always follow the refrigerant system around in a continuous path so that no areas of
potential leaks are missed. If a leak is found, always continue to test the remainder of
the system.
