MAC2000 2.2 Initial Set-Up Checking Vehicles for Possible Contaminated Systems Before every recovery, the MAC2000 automatically samples the refrigerant in the vehicle’s A/C system. If the system fails the purity level required, the unit tests a second time. In the event the system fails a second time, the unit prompts that the hoses be disconnected from the vehicle. Follow the on-screen prompts in order to clean out the MAC2000.
Initial Set-Up MAC2000 Notes: 12 Instruction 2072-0400
MAC2000 3 3.1 Operation Operation MAC2000 Operational Overview The MAC2000 is an EPA-approved, ETL-listed, single-pass recycling system. During the recovery operation, refrigerant is removed from the vehicle and passed through an oil separator and filter drier before entering the storage tank. The MAC2000’s refrigerant weighing system is extremely accurate. It has sophisticated error correction capability that minimizes incorrect readings caused by bumps or vibration.
Operation MAC2000 Main Menu Recovery mode Vacuum mode Charge mode Snapshot mode Next menu • Recovery mode – Recovers and recycles refrigerant from a vehicle’s A/C system. This mode is most often used prior to opening an A/C system to atmosphere to replace a system component. • Vacuum mode – Removes residual air and moisture from a system previously opened to the atmosphere. This mode also allows a technician to verify that the A/C system will hold a vacuum for a certain length of time.
MAC2000 Operation Menu 3 Main menu Identify mode Check tank air Refri data Filter change • Main menu – Returns display to the Main menu. • Identify mode – Identifies refrigerant in a vehicle’s A/C system without having to recover the refrigerant. After the unit is finished identifying the refrigerant the display returns to the Main menu.
Operation MAC2000 Data is collected from inside the vehicle’s passenger compartment by means of the snap-shot transmitter (shown below). This transmitter is powered from the vehicle’s cigarette-lighter, and wirelessly transmits temperature (and optional air flow) data to the MAC2000. Snap-Shot Transmitter Red Temperature Sensor – This sensor should be used on the front A/C vent in the vehicle. The temperature is displayed as “RED TEMPERATURE” on the Snap-Shot mode screen.
MAC2000 Operation 3. Follow the instructions on the screen. A technician will be instructed to connect the high- and low-side service hoses to their respective service ports on the vehicle’s A/C system and open the A/C system’s service-port valves. Connect the red and blue temperature sensors, start the vehicle, then turn the vehicle’s A/C system to its maximum cool or re-circulating setting. 4. Press the unit’s Start key. 5.
Operation 3.3 MAC2000 Recovery Mode The recovery mode removes all refrigerant from the vehicle’s A/C system and stores it in the unit’s internal storage tank. Before recovery begins, however, there must be pressure in the hoses. This prevents inadvertent recovery of air or other contaminants from a leaking system. The MAC2000 will automatically sense the presence of refrigerant and confirm that it is not contaminated before starting the recovery process.
MAC2000 Operation Note: The MAC2000 will automatically restart the recovery process if the unit senses a rise in the A/C system’s pressure. 5. After recovering the refrigerant from the A/C system, close the service-port valves, and then remove the hoses from the vehicle. Observe that the service hoses should remain under vacuum. This ensures that no contaminants are introduced into the A/C system during a recharge process. 6. The technician can now begin repairs on the A/C system. 3.
Operation MAC2000 achieved. When the A/C system reaches the proper vacuum, the unit’s red light and beeper signal evacuation is complete, and the screen reads “Vacuum complete.” If the proper vacuum is not achieved after 7 minutes of evacuation, the process stops, and the technician is prompted to check for a leak. Note: Depending on the altitude, the A/C system may not be able to achieve 27 inHg. It is important that the altitude setting in the SetUp menu is correct for your location.
MAC2000 Operation 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.
Operation MAC2000 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.
MAC2000 Operation 5. Again press Start to continue. The unit now displays “Set Flush Time.” Set the flush time by pressing and holding down the Increase or Decrease key until the desired time is shown. Press Start to accept the flush time shown on the screen. A minimum flush time of 30 minutes is recommended. Important! There must be a minimum of 12 pounds of refrigerant in the internal storage tank in order to complete the System Flush process.
Operation 3.7 MAC2000 Refrigerant Management System The MAC2000’s Refrigerant Management System tracks all aspects of refrigeration usage, which can significantly help in the management of an A/C repair business. In addition, the unit’s software allows a business to meet new federal regulations requiring strict records of refrigerant usage. Refrigerant measurement during charging is extremely accurate.
