Error #21: N2 TEST NOT COMPLETED: This error message is displayed when, when a
previously NITROGEN TEST has not been completed (eg due to switching off the charging
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
 Solution: Check the connections and repeat the procedure. If the problem persists, look
for the leak using the N2+H2 mixture and the special leak detector
Error #26: COMUNICATION ERROR: Error message displayed when the charging station
loses its connection with the sanitiser or external analyzer
 Solution: verify the electrical connections of the sanitiser or the analyzer with the
charging station. Power cycle the charging station
Error #27: LOW OIL VOLUME: error message displayed when the amount of oil / tracer set is
greater than the amount available
 Solution: Fill the oil/tracer container
NOTE: using tracer not recommended by the manufacturer will void the warranty.
NOTE: Use only oils recommended by the manufacturer or vehicle manufacturer.
Never use oil used
Error #30: CHECK CONNECTIONS: error message displayed when the flow rate of filling is
too low
 Solution: Verify the correct opening of the quick couplers, make sure that the amount of
gas in the refrigerant bottle is > 3 kg, otherwise fill the inner refrigerant bottle.
 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.
