Testing for refrigerant leaks
Observe the following notes when testing for
refrigerant leaks:
• Only use the device on systems with suffi-
cient refrigerant and their engines not in
operation.
• Affecting the airflow around the sensor
probe can lead to false refrigerant leak
detection.
Avoid quick or sudden movement of the
device as well as windy conditions during
operation.
1. Place the tip of the sensor probe within
5 mm of the suspected refrigerant leak.
2. Slowly (25-50 mm/s) move the sensor
probe past each suspected refrigerant
leak.
✔ If a refrigerant leak is detected, the device
emits an audible signal and the LED flashes
more rapidly.
