TYPICAL APPLICATIONS

When power is supplied to the exhaust fan, the fan runs, and the solenoid air valve is

energized, closing port 2 and passing main air from port 1 through port 3 to damper actuator,

which opens the normally-closed exhaust damper.

When power is removed from the fan, the fan stops, and the solenoid air valve is de-

energized, closing port 1 and bleeding air from the damper actuator through port 3 and out

port 2 to atmosphere, closing the exhaust damper.
