No data is coming from the
refrigerant scale.
It is not possible to lower the

Remedy
Check the scale.
Check air conditioner and
connections for leaks, con-
strictions and ice build-up.
Check pressure transducer
calibration.
Connect low pressure hose
to the flush box and open
valve.
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.
