Unsuccessful Transfer

Sometimes the total charge does not transfer into the A/C system. There are two reasons why this may occur:

1. The pressure in the unit's tank and the pressure in the A/C system are roughly equal.
   • This will cause the transfer to proceed too slowly.
2. There was not enough refrigerant in the unit's tank to transfer the full charge.
   • It  is necessary to recover the partial charge of refrigerant from the vehicle and then evacuate the A/C system and charge it again.
   • Refer  to the manufacturer's instructions for the charging station in use.
