6. Make sure the Load Auger switch is set to AUTO. In both the AUTO and MANUAL position, the
Grain Level switch will automatically keep the dryer full of grain. In the AUTO position, the dryer will
shutdown after the preset time period on the out of grain timer, or if the grain flow to the dryer
is interrupted.
7. To properly set the correct dry, cool and unload time for various moisture content grains, refer chart

components in their proper order. If any of the selected switches are improperly positioned for staged
batch drying, the display will indicate the proper switch position and will not allow the dryer to operate
until the position of the switch is corrected.
9. The fan will start and airflow is checked.
10. After purging for approximately 10 seconds the heater will fire. For information concerning heater
adjustment, see the dryer pre-start checks
