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.

3.4Vacuum Mode (Evacuation)

The Vacuum mode is used to remove residual air and moisture from the vehicle’s A/C system by pulling the system into a deep vacuum. This mode is most often used after completing a repair that required opening the A/C system to the atmosphere. Moisture and/or air in an A/C system can cause erratic operation and must be removed before recharging the system with refrigerant.

Evacuate a vehicle’s A/C system 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.

2.Connect the high- and low-side service hoses to their respective service ports on the vehicle’s A/C system; then open the A/C system’s service-port valves.

3.Press the Vacuum mode function key and observe that the screen reads “Set VACUUM TIME now.” The minimum evacuation time is 3 minutes. To change this time, press and hold the Increase key until the desired time is shown.

4.Press the Start key to begin the evacuation process.

Note: Before evacuation begins, the MAC2000 checks if pressure is present in the vehicle. If pressure is sensed, the unit will display the message: “Error: You have pressure in the hoses. You must first recover this refrigerant before proceeding.” If this error message appears, first abort the evacuation process by pressing the Reset key, recover the system per Section 3.3, then restart the evacuation process by pressing the Vacuum mode function key.

5.The evacuation process continues for the amount of time set in Step 3. If a vacuum level of at least 27 inHg is not achieved within the prescribed time, the evacuation process automatically continues for a maximum of 7 minutes, or until 27 inHg is
