Auto Sync System
This seldom needs adjusting after the initial setup if the rest of the system is well
maintained.
Note: Do not adjust the Auto Sync components to compensate for problems elsewhere in
the CAFS system.
Before you make any adjustments, make sure the oil level in the sump is correct, the
air and oil filters are not overdue for servicing, the oil is not overdue for changing, the
compressor is not overheating, the oil cooler strainer is clean, and the air lines do not
have leaks.
Always start by adjusting UNLOAD mode, then FIXED, then AUTO.
A common problem is unauthorized adjustment of the balance valve in an attempt to
improve performance. If unauthorized adjustments to the Auto Sync are a problem we
suggest placing a seal over the adjustment points. This will let maintenance personnel
know if the system has been tampered with.
