Startup
Exhaust Fan Operation
To start the optional power exhaust fans, use the economizer test procedures in Table 28, p. 74 to
drive the economizer dampers to the open position. The exhaust fans will start when the damper
position is equal to or greater than the exhaust fan setpoint. If optional power exhaust is selected,
an access door must be field-installed on the horizontal return ductwork to provide access to
exhaust fan motors.
WARNING
Rotating Components!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury.
The Exhaust Fan will start anytime the economizer damper position is equal to or greater than the
exhaust fan setpoint.
