UV dye bottle filling

The UV Dye 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 UV dye can therefore be used to detect leaks of a small
entity inside the auto vehicle A/C system.
To fill the UV dye bottle (Fig.1 Pos. 9) 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 "Active Oil
Protection" system.
•
During the oil suction phase, before entering the bottle
air is made dry as it passes through a path of special
"desiccant" material.
•
The air inside the bottle is therefore completely "dry"
After filling, close the bottle and place it back in its seat.
