12. Run the fan(s) and heater(s) for about 10% longer than the (APPROX. DRYING TIME) required for the
moisture you are trying to dry.
13. Example: 10% removal would be about 54 minutes, 15% removal would be about 76 minutes and 20%
removal would be about 100 minutes. Add 10 minutes to insure that the grain is dry.
14. After the time in step 12 turn the UNLOAD to 1 SPEED and set the METER ROLL SPEED, (HIGH
SPEED). to the setting for 1 SPEED operation. Grain should begin to run at this time. Run time for this is
about 10% longer than the (APPROX. DRYING TIME) required for the moisture you are trying to dry. This
allows the moisture in the dryer to reach an even gradient top to bottom without having any highs or lows in it.
It will however, over dry some of the corn a little.
15. Increase the drying temperature to 190 deg. for single fans or for multiple fan dryers set the heat cham-
bers 30 to 60 degrees apart. Hottest at the top, most cool at the bottom.
16. DO NOT TRY TO ADJUST THE DRYER FOR MOISTURE DURING THIS PROCESS OR YOU WILL
ESTABLISH HIGH AND LOW SWINGS IN THE MOISTURE CONTROL. IT WILL TAKE SEVERAL HOURS
TO WORK ITSELF OUT.
17. After the run time in step 14 you are ready to set up the moisture control. Now turn the MOISTURE
CONTROL to the ON position. Set the temperature to about 100 deg.
18. Turn the UNLOAD to 2 SPEED. Set the METER ROLL SPEED, LOW SPEED and HIGH SPEED. to the
settings listed for them. Let the dryer run on these settings before trying to adjust moisture or meter roll
settings. These settings will not have your grain moisture adjusted exactly where you want it, but will be a
good place to start initially. A little different moisture at the bottom of the storage bin is not usually a problem
as long as you have full floor aeration.
19. After the run time in step 18 you are ready to adjust the moisture control, and the meter roll speeds if
required. Each time you make an adjustment to the moisture control it will take about the time shown in the
drying charts to see the results of this adjustment.
Dry and Cool-Continuous Flow Operation
1. Turn the control power switch to on.
2. After the date and time appear on screen, press the button.
3. Turn the DRYING MODE switch to CONT. FLOW.
4. Make sure the UNLOAD switch is OFF.
5. Make sure the MOISTURE CONTROL switch is OFF.
6. Open the main fuel supply valve on the tank if using LP gas, or open the fuel supply line if using natural
gas. Turn on the Maxon electric shut off valve, if so equipped, or open the manual shut off valve to allow fuel
flow to the dryer.
7. Push the DRYER POWER START switch.
8. The dryer should already be filled with grain. Turn the LOAD AUGER switch to the AUTO position. In both
the auto and manual positions, the dryer grain level switch will automatically keep the dryer full of grain. In the
auto position the dryer will shut down after a preset time period on the out of grain timer.
