Maintenance

MAC2000

Caution: The filter drier should not be changed with the MAC2000 still connected to the vehicle. Disconnect the unit by closing the vehicle’s service-port valves and disconnecting the high- and low-side hoses from the vehicle.

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.From the Main menu, press the Next menu function key to display Menu 2.

3.Follow the on-screen prompts; then press the Start key to begin evacuating the filter.

4.When completely evacuated, follow the on-screen prompts and remove the old filter drier by unscrewing it counterclockwise. Dispose of the used filter in a proper manner.

5.Lubricate the O-rings of a new filter drier with a light grease or saliva; then hand tighten until it bottoms out.

6.Press the Reset key after the new filter has been installed. This will remove any air that may have entered the system during the changeover process.

4.2Replacing the External Source Tank

The internal storage tank contains enough refrigerant for several jobs, but it’s important to replace the external source tank soon after the message “Source Tank empty” is displayed so that the internal storage tank isn’t depleted during a charge operation.
