8.3 TRACER BOTTLE FILLING
The tracer is a substance made up of a yellow-green coloured fluorescent pigment, which means
that, when lit by an ultraviolet lamp, it becomes fluorescent and thus visible.
The tracer can therefore be used to detect leaks of a small entity inside the auto vehicle A/C system.
The tracer bottle is on the right – looking at the unit from the front side.
To fill it, it has to be extracted from its housing by means of the quick coupler on the top of the
bottle; slightly press downward the coupler ring nut to extract it.
Fill the bottle by paying special attention to the “oil care” valve.
This valve is made of a silicon polymer membrane; it compensates pressure variations within the
bottle and stops humid air infeed inside thus preserving the new oil inside.
After filling, close the bottle and place it back in its seat.
