DRYER START UP

9.If the dryer is being operated in all heat, turn the FAN switch to ON. In this position the fan will run continuously during the dry, cool and unload stages of the staged batch operation. If the dryer is being operated in the dry and cool mode, the preferred position for the FAN switch is the ON position, so the fan will run continuously. If desired, the fan can be turned off during the un- load cycle of the dry-cool-unload sequence by turning the FAN switch to AUTO.

10.If the dryer is being operated in all heat, turn the HEATER switch to ON. The burner will operate whenever the fan is operating. If the dryer is being used in dry and cool, turn the HEATER switch to AUTO and the burner will automatically shutdown during the cooling and unloading cycles.

11.Turn the UNLOAD switch to the 1 SPEED position. The bottom auger and metering rolls will

start automatically during the unload cycle of the dry-cool- unload mode, along with any grain handling equipment that is wired to the dryer. The speed at which the metering rolls operate during the unload cycle is adjusted by using the HIGH SPEED METERING roll dial. Turning the dial clockwise will INCREASE the grain dis- charge rate, and counterclock wise will DECREASE the dis- charge rate.

12.To control the length of the dry cycle using only the dry time setting programmed into the system, turn the MOISTURE CONTROL setting to OFF. To use the automatic moisture con- trol so that the dry time is deter- mined, not only by the dry time setting, but also by the moisture content of the drying grain, turn the MOISTURE CONTROL switch to ON.

13.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 se- lected switches are improperly positioned for staged batch dry- ing, the display will indicate the proper switch position, and will not allow the dryer to operate until the position of the switch is corrected.

14.To shutdown the dryer, CLOSE the FUEL SUPPLY valve at the fuel tank or fuel source. If the burner is operating, let the dryer run out of fuel causing an auto- matic shutdown due to a loss of flame. CLOSE the FUEL VALVE at the dryer, and press the dryer POWER STOP button. Turn OFF the dryer's main CIRCUIT BREAKER located on the front of the power panel. Turn OFF the MAIN main POWER SUP- PLY to the dryer.

15.In case of an emergency press the dryer POWER STOP button. The burner, fan and all augers will stop immediately.
