Farm Fans C-2120A, Operator'S Manual, Page: 21 / 68

Push the STOP button. All fans, burners, and augers
should immediately stop operating as the button is
depressed.
With the dryer properly functioning as described in the
previous steps, the unit can be considered ready for
drying operation. Refer to Section 5 - Dryer Operation
for procedure and control settings.
NOTE: Each time the stop button is depressed or the
dryer shuts down, the Main/Safety Gas Shut-off valve
will become de-energized and its handle will trip
closed. The valve handle must be manually opened to
allow gas flow for burner operation.
Shut off the circuit breakers and main power supply,
and close fuel supply valves if you are not ready to
begin the drying operation.
