Turn the LOAD switch to ON and Fill the dryer with grain. The load auger will stop when full if the LOAD TILT Switch is installed and set properly.
3.Turn the drying mode switch to staged batch.
4.Open the main fuel supply valve on the tank if using LP gas, or the valve in the fuel supply line if using natural gas. Turn ON the electric shut off, Maxon valve (if so equipped), or open the manual shut off valve to allow fuel flow to the dryer.
5.Set switches to the following settings:
Load | AUTO (For timed shut down when out of grain. ON will shut off auger when | |||
|
| full, but will not shut dryer down when out of grain.) | ||
Fan | AUTO (To Stop during Unloading. ON to Continue Cooling during Unloading.) | |||

At the end of the dry cycle in staged batch, the fans and heaters will continue running if the MOISTURE CONTROL is “ON”, until the preset temperature on the moisture control thermostat is reached.
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 shut down 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, see the chart on Page 30.
8.To start the drying operation, push the dryer power start button.The controller will start all the dryer 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.
