Anleitung Zusammenfassung


This prevents air and other contaminants from being introduced into the A/C system. If the message “The vehicle is not properly evacuated” appears, perform one of the following: • If the refrigerant in the A/C system has just been recovered, evacuate both the system and the service hoses per Section 3.4. • If the A/C system needs to be “topped off,” first ensure that the service hoses are disconnected from the vehicle; then either recover the hoses per Section 3.3 if they contain refrigerant, or evacuate the hoses per Section 3.4 if they contain air. 3. After entering the Charge mode, the following options are available: • Press the Enter key to accept the 2.00 pound Default. • Press the Weight Convert key to change the “Set charge weight” units. • Use the Increase or Decrease keys to set the desired charge amount. Select the next higher value if the exact charge amount cannot be entered. Press Enter to accept the charge amount shown on the screen. Note: The MAC2000 charges in one-ounce increments, regardless of which unit of measure is selected. This means that sometimes the exact charge amount cannot be entered. For example, the A/C system may require a 1.03 kg charge. The MAC2000 will only allow a setting of 1.02 kg or 1.04 kg. In this instance, always select the next higher value. This difference is only 0.3 of an ounce, which will not affect the vehicle’s A/C performance. 4. By default the MAC2000 charges liquid refrigerant directly into the high side of the A/C system. A technician, however, may choose to charge into both the high and low side by pressing the Low side ON-OFF function key. Pressing this key toggles the low-side option on and off. Important! Charging liquid directly into the low side of the compressor could slug the compressor and cause permanent damage. Check with the compressor manufacture before proceeding. 5. The screen should now show the amount of refrigerant set for charging. Press the Start key to begin the charging process. During the charging process, liquid refrigerant is drawn from the unit’s internal storage tank and charged through the high side (and optionally the low side) of the vehicle’s A/C system. The screen will show the progress of this charging process. Important! Do not disturb or bump the MAC2000 during charging as any jarring movement can affect the charge accuracy. Note: If an insufficient pressure differential exists between the tank and the system, charging suspends and the MCR2000 goes into a power-charge mode to increase tank pressure to complete the charge. This normally occurs only when the unit has been in a very cold environment prior to use. 6. When charging is complete, the red light and beeper signal that the process is complete. The MAC2000 automatically goes into the Snap-Shot mode, thus allowing a technician to obtain an after- service snap-shot of important operating parameters of the A/C system. Refer to Section 3.2 for details. 7. If more refrigerant needs to be added, press the Additional Charge function key. Otherwise, press the Done function key to exit the Snap-Shot mode. 8. Close the service-port valves; remove the service hoses from the vehicle; then press the Start key to recover the hoses. Important! If the hoses are not removed from the vehicle before the Start key is pressed, the refrigerant in the vehicle will be recovered! 9. If any oil was removed during the recovery or evacuation process, make sure that the proper amount of oil is added back into the vehicle’s A/C high side port in accordance with the vehicle manufacturer’s recommendations. Add an amount of new oil equal to the amount collected in the oil drain bottle (see MAC2000 Left- Side View, Page 5). 3.6 System Flush Mode (Oil Flush) The System Flush mode is designed to be used on General Motors vehicles using their Oil Flush Adapter and Filter accessory. This accessory is attached inline with the vehicle’s compressor and is used to flush the A/C system with refrigerant. In this mode, refrigerant is circulated through both the A/C system and the MAC2000 where an oil separator removes the oil and returns oil-free refrigerant back into the A/C system for further flushing. At the end of the cycle, the refrigerant is completely removed from the A/C system and stored in the unit’s internal storage tank. The flushing process can take up to 30–45 minutes to complete. Because of the variety of A/C system configurations currently in service, the flush may bypass certain sections of the A/C system. To ensure the complete system is flushed, the technician may need to pinch off certain hoses to force the refrigerant flush throughout the system. 1. Before beginning the flushing process, recover all refrigerant from the vehicle’s A/C system per Section 3.3 Recovery Mode. 2. From the Main menu, press the Next menu function key to display Menu 2, and then press the System flush function key to select the System Flush mode. The unit reminds the technician to “Please empty the purge oil bott...
