Operation

MAC2000

3.3Recovery 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.

Begin the refrigerant recovery process 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.Press the Recovery mode function key and observe the following message: “Hook-up the service hoses to vehicle.”

3.At this time hook up the service hoses, open the A/C system’s service-port valves, and then press the unit’s Start key. The refrigerant identifier will warm up, zero itself, and then display the message “Analyzing sample, please wait . . .”

If the refrigerant is contaminated (meaning that it has somehow been mixed with some other kind of refrigerant), the results will be displayed along with the word “contaminated.” Note that the unit will not allow the recovery operation to proceed when refrigerant is contaminated.

If the refrigerant is found to meet specifications, the unit will automatically proceed to recover the refrigerant. During the recovery operation, refrigerant is removed from both the high and low side of the vehicle’s A/C system. The screen will display “Recovering refrigerant” along with showing the amount of refrigerant being recovered.

4.When the A/C system has been recovered to a minimum vacuum of 9 inHg, the recovery process automatically stops. The following events then occur:

•The unit’s red light flashes and the beeper sounds, signaling the technician that recovery is complete.

•The screen reads “Recovery complete” and shows the weight of the recovered refrigerant.

•System oil is automatically drained into the oil drain bottle (see MAC2000 Left-Side View, Page 5).
