Cause
It is not possible to lower the
pressure when flushing takes
place.
During the flushing process,
no pressure could be ascer-
tained at the low pressure
connection of the air condi-
tioning service unit.
During the software test, the
compressor failed to reduce
the internal pressure suffi-
ciently.
It was not possible to drain
any used oil during the
software test.
It was not possible to remove
any refrigerant from the
internal tank during the
software test.
No USB stick was found/
recognised
Troubleshooting
Remedy
Check air conditioner and
connections for leaks, con-
strictions and ice build-up.
Check pressure transducer
calibration.
Connect low pressure hose
to the flush container and
open valve.
Residual pressure on the
pressure gauges?
Check pressure transducer
calibration.
Check internal bottle
pressure.
Check the compressor and
the corresponding solenoid
valves.
Is there residual oil in the dis-
tillator, or was the draining of
used oil interrupted during
the last process?
Insert bottle for used oil
correctly.
Is there a vent hole in the
used oil container / is the
vent hole clogged?
Check pressure transducer
calibration.
Check whether the tank
valve on the internal tank is
open.
Check the RE valve.
Is the ambient temperature
below 10 °C?
Insert the USB stick.
Make sure that the USB stick
has been formatted with the
FAT32 file system.
