SECTION  4.  VERIFYING THE AUTO SYNC AIR BALANCING 

SYSTEM 

 

This system seldom needs adjusting. For pre-built CAFS, the Auto Sync system is adjusted at the 
factory before shipment. In most cases the factory settings will be satisfactory for typical CAFS 
and auxiliary air applications. If the system fails any verification step, go to Adjusting the Auto 
Sync Air Balancing System and follow the steps in the order given. 

 

A. UNLOAD mode verification 

 

1. Set the controls on the Auto Sync control panel to UNLOAD (center position). 

 

Electric Auto Sync Controls 

 

 

 

 

 

 

2.  Completely close all air discharges. 

 

3.  Start the engine.
