Leak Detector Usage Tips (Refer to the Operator's Manual for complete operating instructions)

Position the vehicle in a wind-free work area. This will aid in detecting small leaks.
When using the leak detector for the first time, allow it to warm up for 2 minutes with the probe in a clean atmosphere. This lets the temperature sensor in the detector stabilize.
The calibration check should be done in the "Search 2" mode. Once that is done, the other check modes do not need calibrating.
When leak checking through the HVAC module drain hose, avoid drawing water into the probe. Water can damage the internal pump and sensor.
Avoid creasing the flexible probe extension. Creases can restrict air flow and give false readings.
Because the detector recalibrates itself for ambient gases, it may be necessary to move the detector away from the leak to clear the sensor. Once the sensor has cleared, recheck the suspected leak.
When removing the clear probe tip, be careful not to lose the flow ball.
R-134a is heavier than air; always check below and to the sides of all potential leak sources.
Halogen leak detectors are sensitive to chemicals: windshield washing solutions, solvents/cleaners, and some vehicle adhesives. Keep these chemicals out of the area when doing leak detection.
