station)

Solution: Follow the onscreen instructions to purge the nitrogen present in the charging
station
Error #22: N2 PRESSURE INSUFFICIENT: error message appears during N2 TEST
because the inlet nitrogen pressure is very low and is not sufficient for the proper performance
of the test.

Solution: Check the connections between the external nitrogen bottle and the charging
station, verify that the external nitrogen bottle is open, and that the pressure regulator is
positioned between 8 and 12 bar
Error #23: N2 TEST LEAKS: error message displayed when the charging station encountered
leaks during the NITROGEN TEST. A /C system is not in tight

Error #27: LOW OIL VOLUME: error message displayed when the amount of oil / tracer set is
greater than the amount available

Rarely, it may happen that the temperature of the engine compartment of the vehicle is
too high compared to that of the charging station, this can cause an immediate balance
between the refrigerant bottle pressure and A/C pressure causing a slowdown or
interruption of the filling. To avoid this it is recommended not to do fill A/C in a vehicle
exposed to the sun or a vehicle with the engine running.
