MAC2000 Maintenance
4 Maintenance
Field maintenance of the MAC2000 is limited to the following:
• Changing the filter drier
• Tracking of refrigerant using the unit’s Refrigerant Management
System
• Replacing the external refrigerant source tank
• Replacing the printer paper
• Replacing the refrigerant identifier filter
All other maintenance should be performed by an authorized
Bacharach Service Center (Section 5.2).
4.1 Changing the Filter Drier
The MAC2000 has a unique filtering system that ensures the
refrigerant transferred to the storage tank is clean and moisture-free.
The filter drier must be changed periodically to ensure that the
system will work properly.
The MAC2000 will automatically indicate when the filter needs to be
changed. If the “Change Filter” message appears when the Recovery
mode is selected, it is best to complete that job before changing the
filter drier. “Change Filter” will be displayed on the screen
whenever the recovery mode is selected until the filter has been
replaced.
All refrigerant must be evacuated from the old filter before it is
removed from the unit. Follow the filter change procedures carefully
to minimize refrigerant loss and ensure only clean, moisture-free
refrigerant is transferred into the storage tank.
