UT336A User Manual
the sensitivity to repeatedly locate the concrete leak source.
④ Mark it down then go on the detection for other parts of the whole refrigerating system
when the leak location is concreted.
Notes:
●
The detection will also be effected by other pollutants, using dry cloth to cleanly wipe and dry air
to blow the leak area before the redetection to avoid any inaccuracy, and then repeatedly detect
to find the leak location.
●
Following is for the obvious leak detection:
Firstly, use compressed air to blow and clean the potential leak area, and repeatedly detect to
locate the correct leak location. Secondly, move the probe to the environment with fresh and
clean air to reset, then put the probe to the surrounding of leak location, moving probe slowly to
locate the leak source.
6.4 Cautions
a) Oil and dust is existed in most of leak conditions, we should prevent the probe from
contacting any pollutants, any moisture or other solvents.
b) If any halogen pollution is detected in the condition, ensure without leaving the polluted
condition to use RESET button to ignore the leak halogen in the environment.
c) It is suggested to use wind shields to isolate the detection site or shield the leak area to
prevent the leak air from spreading or diluting during the detection.
d) Check if the refrigerating system has its normal pressure during the leak detection, or the
part of refrigerating system is at least 50PSI to avoid missing the leak detection due to
the low pressure.
