Cause
It was not possible to reduce
the pressure sufficiently
during the "Software test".
It was not possible to drain
any used oil during the
"Software test".
It was not possible to remove
any refrigerant from the
internal vessel during the
"Software test".
The compressor could not
reduce the internal pressure
sufficiently.
Low pressure hose is leaking
or connected to an (empty)
air conditioning unit. Vacuum
could not be reached.
Low pressure hose is leaking
or connected to an (empty)
air conditioning unit. Vacuum
could not be reached.
Not enough vacuum.
Pressure increase during
vacuum test.
Not sufficient pressure for
refrigerant pressure test.
Pressure drop during leak
test.
Troubleshooting
Remedy
Residual pressure on the
pressure gauges?
Check pressure transducer
calibration.
Check internal bottle pres-
sure.
Check the compressor and
the corresponding solenoid
valves.
Insert receptacle for drained
oil correctly.
Check that the solenoid valve
can move freely.
Check that the scale is work-
ing properly.
Check pressure transducer
calibration.
Check if the valve on the
internal vessel is open.
Check the RE valve.
Check the compressor and
pressure transducer.
Disconnect service hose
from the unit.
Disconnect service hose
from the unit.
Check device and used oil
container for leaks.
Check the vacuum pump.
Check unit for leaks.
Check unit for leaks.
Check the refrigerant
quantity.
Is the ambient temperature
more than 10°C?
Check unit for leaks.
