• Ensure all connections are tight to prevent leaks.

5. Operating Instructions

The ATC-913A features a semi-automatic operation controlled via an LCD display and touch keys.

5.1 Control Panel Overview

The LCD screen (6 in Figure 1) displays functions and allows setting parameters. Use the touch sliding keys for interaction.

• Choice Button: Navigates through available functions (Recovery, Vacuum, Refrigerant).
• Add/Subtract Keys (10 in Figure 1): Adjusts numerical values (e.g., vacuum time, charge amount).
• Start/Stop Button: Initiates or terminates a selected operation.
• Print Button (11 in Figure 1): Prints operation data (if printer function is available).

5.2 Refrigerant Recovery

1. Connect the high and low-pressure hoses to the vehicle's AC system.
2. Turn on the machine.
3. Press the Choice button until 'Recovery' is selected on the LCD.
4. Use the Add/Subtract keys to set any desired recovery parameters (if applicable).
5. Press Start/Stop to begin the recovery process. The machine will automatically recover refrigerant from the vehicle.
6. Monitor the gauges (1, 2, 3 in Figure 1) and the refrigerant window (14 in Figure 1) during the process.
7. The machine will stop automatically once recovery is complete.

5.3 Vacuuming

1. Ensure hoses are connected to the vehicle's AC system.
2. Press the Choice button until 'Vacuum' is selected on the LCD.
3. Use the Add/Subtract keys to set the desired vacuum time (e.g., 15-30 minutes).
4. Press Start/Stop to begin the vacuum process. The machine will evacuate air and moisture from the AC system.
5. The machine will stop automatically after the set time. Observe the low-pressure gauge to ensure the vacuum holds, indicating no significant leaks.

5.4 Refrigerant Charging

1. After vacuuming, ensure the system holds vacuum.
2. Press the Choice button until 'Refrigerant' (or 'Charge') is selected on the LCD.
3. Use the Add/Subtract keys to set the precise amount of refrigerant to be charged (0.1~12kg range). The electronic weigh scale ensures accuracy (±10g).
4. Press Start/Stop to begin charging. The machine will automatically charge the set amount of refrigerant.
5. The machine will stop automatically once the set amount is charged.
