AUTOMATIC

1.Set up the AC880 and turn the Main Power Switch ON.

2.Attach the Red and Blue Hoses to the A/C System per the vehicle manufacturer's instructions and open the Red and Blue Hose Valves.

3.Determine the refrigerant capacity of the A/C System to be charged.

Note: 1 oz = 0.02835 Kg 1 Lb = 0.45359 Kg

4.Using the Keypad, press the ENTER key when the Display reads “WEIGHT= XX.X LB” “AUTOMATIC? #” (this is the default screen of the Main Menu.) The Display will read “RECYCLE HOLD” “TIME XX MIN #”.

The Recycle Hold Time is the amount of time that the AC880 waits for “out- gassing” or for the pressure in the A/C System being recovered to rise enough to automatically restart the recovery process. The minimum value is two minutes. The value entered is stored in memory and displays as the default the next time the procedure is used.

5.Press the “Up Arrow” key to change the value of the field. Press the “Right Arrow” key to change to a different field. Press the ENTER key to accept the value. The Display will read “ENTER VACUUM” “TIME XX MIN #”.

6.Press the “Up Arrow” key to change the value of the field. Press the “Right Arrow” key to change to a different field. Press the ENTER key to accept the value. The Display will read “PERFORM LEAK” “TEST? Y/N#”.

7.Press the “Right Arrow” key to move the cursor between Y and N to select whether or not the AC880 pauses at the end of Vacuuming so that a vacuum leak can be detected in the A/C System. Press the ENTER key to accept the Yes or No choice. The choice entered is stored in memory and displays as the default the next time the procedure is used. The Display will read “ADD OIL? Y/N#”.

8.Press the “Right Arrow” key to move the cursor between Y and N to select whether or not the AC880 pauses at the end of Vacuuming (or Vacuum Leak Checking) to allow the Adding of Oil to the A/C System. Press the ENTER key to accept the Yes or No choice. The choice entered is stored in memory and displays as the default the next time the procedure is used. The Display will read “ENTER CHARGE” “AMOUNT= XX.X LB#”.

9.Press the “Up Arrow” key to change the value of the field. Press the “Right Arrow” key to change to a different field. The value entered must be greater than zero. Press the ENTER key to accept the value. The Display will read “CHECK HIGH-LOW” “CHARGE SWITCH #”.

*This screen will display if the AC880 Charge Cylinder contains less refrigerant than the entered value. When this occurs, the charging Cylinder should be filled using the Fill Cylinder procedure on Page 5. Press the ENTER key to return to the Main Menu.

10.Based on the vehicle manufacturer’s instructions, choose Charging through either the High Pressure Hose (preferred) or the Low Pressure Hose by pressing the top or bottom of the High-Low Charge Selector Switch (12). Press the ENTER key when finished programming. The Display will read “CHECK HOSES” “START? #”.

Note: Do Not Turn On The A/C System. SAE compliant refrigerant handling stations, like the AC880, supply refrigerant in the liquid phase. Adding liquid refrigerant to a running A/C System may cause immediate A/C compressor failure.

11.Press the ENTER key to start the Automatic sequence.
