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

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

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.
