Where “w:yz” refers to the quantity for the vehicle selected. The machine will be ready to enter the correct quantity of refrigerant. Confirm by
pressing the ENTER key.
Open the high and low service valves on the machine and press the START key (in the case of an A/C system with a single high or low pressure
coupling, open only the relative valve on the machine).
NOTE: Charging may not run to completion due to pressure balance between the internal tank and the A/C system. If this occurs, close the valve
on the high pressure quick connect coupling (leaving the low-pressure side open), turn on 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:
