To Next PageTo Next PageWhat does it mean when my Waeco AirConServiceCenter VAS 6746B displays “WARNING ! Not enough vacuum for injection!”?
This message appears during the filling phase if the vacuum in the air conditioning system is insufficient to end the process. Check the air conditioning system or the connections between it and the AirConServiceCenter for leaks.
What does it mean when Waeco AirConServiceCenter VAS 6746B Service Equipment displays “Drained oil glass emptying.”?
This message appears during the extraction or recycling process if there is more than 150 ml of used oil in the container. Dispose of the content of the used oil container in an environmentally responsible manner.
What should I do if my Waeco Service Equipment displays “Not enough refrigerant! Add !”?
This message appears during the filling process if there is not enough refrigerant in the internal container to finish the process. Fill the refrigerant container.
What to do if Waeco AirConServiceCenter VAS 6746B displays “Printer not in line. Carry on?”
This message indicates a printer fault. Check if there is paper in the printer, if the printer is switched on (yellow LED must light up constantly), and that the cover is closed properly.
What to do if Waeco Service Equipment displays “WARNING ! Internal vessel filled.”?
This indicates that the internal refrigerant container is too full to hold the quantity to be extracted. Drain the internal refrigerant container in the proper manner.
Why does my Waeco AirConServiceCenter VAS 6746B display “Error 03”?
This error indicates that no data is coming from the refrigerant scale. Check the scale.
What does it mean when my Waeco Service Equipment displays “Error 10”?
During the software test, the compressor failed to reduce the internal pressure sufficiently. Check for residual pressure on the pressure gauges, check pressure transducer calibration, check internal bottle pressure, and check the compressor and the corresponding solenoid valves.
What does it mean when Waeco Service Equipment displays “Error 12”?
It was not possible to remove any refrigerant from the internal tank during the software test. Check pressure transducer calibration. Check whether the tank valve on the internal tank is open. Is the ambient temperature above 10 °C?
What does “A/C System leakage. Carry on?” mean on my Waeco Service Equipment?
This message appears at the end of the vacuum process. The air conditioning system shows a vacuum loss of more than 120 mbar during the checking time. Check the air conditioning system or the connections between it and the AirConServiceCenter for leaks.
What to do if Waeco AirConServiceCenter VAS 6746B Service Equipment displays “WARNING ! Not enough oil. Add.”?
This message appears during the filling process if there is not enough fresh oil in the container to finish the process. Top up the fresh oil container with a suitable oil type.
