The 69788 can be programmed to complete a continuous recovery/recycle, vacuum, vacuum leak test and recharge. New A/C systems are smaller. Machines must charge within .5 oz and recover 95% of the refrigerant. The machine can also be set to run each operation individually. Includes refrigerant capacities for US and Import makes and models from 1995 to 2010. The 69788 is capable of software upgrades as well. Pauses cycle and monitors vacuum level to inform the technician of possible leaks. Oil is automatically discharged during the recovery process into a graduated container clearly displaying the amount of oil that was removed during the recovery process. Automatically purges air from the tank upon initial start-up or when the tank pressure is too high.
