Solution: verify the electrical connections of the analyzer with the charging station.
Power cycle the charging station
LOW OIL VOLUME: error message displayed when the amount of oil set is greater than the
amount available
Solution: Fill the oil/tracer container
NOTE: Use only oils recommended by the manufacturer or vehicle manufacturer.
Never use oil used
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.
EMPTY EXTERNAL BOTTLE: error message appears during the process of filling the
refrigeant bottle when the pressure drops to zero before the completion of the procedure
Solution: Check the connections, quick couplers and valves on the external bottle; if the
external bottle is empty, replace it with a full one, then run another filling.
HIGH PRESSURE ALARM: error message appears during the recovery procedure, internal
bottle filling, emptying hoses, flushing hoses or A/C system flushing, this occurs when the
hydraulic pressure reaches approximately 20 bar. The causes may be:
Ambient temperature where is located in the station is too high. Solution to wait for a
sufficient time to cool the charging station before resuming the interrupted procedure.
Number of services performed by the station is excessive. Solution to wait for a
sufficient time to cool the charging station before resuming the interrupted procedure.
One of the taps of the internal bottle is closed. Solution to open the tap and resume the
