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. A message will be displayed if additional refrigerant needs to be added. Add additional refrigerant by following the procedure described in Section 3.8 Internal Tank Manual Refill.

6.Press the Start key to begin flushing. The MAC2000 begins flushing the A/C system in the following manner:

The A/C system is first completely filled with refrigerant, during which time the screen shows “Flushing – Charging.”

The system is now flushed for the time duration set in Step 5, during which time the screen shows “Flushing system.”

After the system is flushed, all refrigerant is automatically recovered. The screen shows “Recovering refrigerant” during this process.

The flush cycle completes by draining the oil that was removed during the flushing process into the unit’s oil drain bottle (see MAC2000 Left-Side View, Page 5). The screen shows “Draining oil” during this process.

Important! All oil was removed from the A/C system during the System Flush operation. Be 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.

7.The unit beeps and its red light flashes to indicate that the flushing cycle is complete. The screen now reminds the technician to remove the inline flushing adapter, and to reinstall the orifice tube or TXV valve.

8.Evacuate and then recharge the A/C system per Sections 3.4 and 3.5.
