PRINCIPLES OF OPERATION
VACUUM BREAKER
The Vacuum Breaker System utilizes the stored air on the truck chassis to control an air actuated
butterfly valve. The butterfly valve opens when the amount of vacuum in the system needs to be
reduced.
The vacuum breaker can be controlled from a switch on the Side Opreator’s Panel, a rotary switch
on the Remote Pendant (if installed), and from the Wireless Remote.
Once the Vacuum Breaker is opened at one location, it must then be closed by the same switch.
Example: If the vacuum breaker is opened using the rotary switch on the Remote Pendant, it can
only be closed using the same switch on the Remote Pendant.
There is a light on the Side Opreator’s Panel to indicate the vacuum breaker has been closed.
There is no light indication on the Remote Pendant.
