If any residual refrigerant is left in the A/C system, as indicated by an increase in pressure during the oil discharge phase, recovery will automatically
restart.
NOTE: Stopping the recovery phase before the oil is discharged may damage the recovery/recycle machine's compressor.
Upon completion of discharge, the machine will check for the presence of air in the tank, and if it's necessary, purge the non-condensable gases.
The alarm will sound continuously and the display will show:
The Recovery/Recycle machine will automatically purge non-condensable gases (NCGS) if excess NCGS are detected at the end of recovery. Allow
the unit to complete this procedure, eliminating the chance of NCGS being charged to the AC system.
NOTE: Charging may not run to completion due to pressure balance between the internal refrigerative storage tank and the A/C system. If this occurs,
close the high pressure valve (leaving the low-pressure side open), start the vehicle and switch on the A/C system. The unit is equipped with a tank
heater to limit this occurrence. When the charging operation is complete, the machine will display the following dialog boxes:
