MAC2000 Operation 3 Operation 3.1 MAC2000 Operational Overview The MAC2000 is an EPA-approved, ETL-listed, single-pass recycling system. During the recovery operat ion, refrigerant is removed from the vehicle and passed through an oil separator and filter drier before entering the storage tank.
Operation MAC2000 Main Menu Recovery Vacuum Charg e Snapshot Next mode mode mode mode 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.
MAC2000 Operation Menu 3 Main Identify Check Refri Filter menu mode tank air data 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 refrig erant.
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.
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.
Operation MAC2000 3.3 Recovery Mode The recovery mode removes all re frigerant 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.
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.
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 evacuat ion, the process stops, and the technician is prompted to check for a leak.
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.
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.
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.
Operation MAC2000 3.7 Refrigerant Management System The MAC2000’s Refrigerant Managemen t System tracks all aspects of refrigeration usage, which can sign ificantly help in the management of an A/C repair business. In addition, the unit’s software allows a business to meet new federal regula tions requiring strict records of refrigerant usage.
MAC2000 Operation • Total Flush ........ Time spent flushing and number of times it was performed • Recovered ......... Total amount of refrigerant recovered • Charged .
Operation MAC2000 3.9 System Set Up When the MAC2000 is initially turned on for the first time, the unit automatically enters its System Set-Up mode. The unit must then be set up by following the on-screen prompts before it can be used.
MAC2000 Operation Perform a refrigerant identity check as follows: 1. If not already done, plug the MAC2000 into a properly grounded AC outlet; set the Power switch to ON; then wait until the unit completes its self diagnostics. The screen will display “ Select mode ” when ready.
Operation MAC2000 4. Depending on the percentage of air found in the internal tank, perform one of the following: • If the display shows “ Identifier result: EXCESSIVE ,” then purge the tank by first pressing the Reset key to display the message “ Would you like to purge air? ” Then press the Start key to begin purging air.
MAC2000 Maintenance 4 Maintenance Field maintenance of the MAC2000 is limited to the following: • Changing the filter drier • Tracking of refrigerant using the unit’s Refrigerant Management Syst.
Maintenance MAC2000 Caution: The filter drier should not be changed with the MAC2000 still connected to the vehicle. Disconn ect the unit by closing the vehicle’s service-port valves and disconnecting the high- and low-side hoses from the vehicle. 1.
MAC2000 Maintenance To replace the external source tank: 1. Close tank valve; remove yellow hose from tank valve; release tank strap; then remove tank from side of unit. 2. Place a new source tank on the shelf and secure it with the tank strap. The tank strap must be set up to supply liquid – this usually means the tank is inverted .
Maintenance MAC2000 4.4 Replacing the Refrigerant Identifier Filter Caution: Visually inspect the Refrigerant Identifier Filter every day. If it begins to turn red, replace it immediately! You risk damaging the identifier sensor if the filter is not replaced.
