This manual describes the operation and service for all standard production model dryers. These models
are available for liquid propane or natural gas fuel supply, with either 1 phase 230 volt, or 3 phase
230 or 440 volt electrical power.
Our foremost concern is your safety and the safety of others associated with this equipment. We want to
keep you as a customer. This manual is to help you understand safe operating procedures and some
problems which may be encountered by the operator and other personnel.
As owner and/or operator, it is your responsibility to know what requirements, hazards and precautions
exist, and to inform all personnel associated with the equipment or in the area. Safety precautions may be
required from the personnel. Avoid any alterations to the equipment. Such alterations may produce a very
dangerous situation where SERIOUS INJURY or DEATH may occur.

Safety Precautions
READ THESE INSTRUCTIONS BEFORE INSTALLATION AND OPERATION
SAVE FOR FUTURE REFERENCE
1. Read and understand the operating manual before attempting to operate the dryer.
2. NEVER operate the dryer while the guards are removed.
3. PowersupplyshouldbeOFFforserviceofelectricalcomponents.UseCAUTION incheckingvoltage
or other procedures requiring the power to be ON.
4. Check for gas leaks at all gas pipe connections. If any leaks are detected, DO NOT operate dryer.
Shutdown and repair before further operation.
5. NEVER attempt to operate the dryer by jumping or otherwise bypassing any safety devices on
the unit.
6. Set pressure regulator to avoid excessive gas pressure being applied to the burner during ignition
and when the burner is in operation. See Chart on Page 18 for operating procedures. DO NOT
exceed maximum recommended drying temperature.
7. Keep the dryer clean. DO NOT allow fine material to accumulate in the plenum chamber.
Clean grain is easier to dry. Fine material increases resistance to airflow and requires removal
of extra moisture.
8. Keep auger drive belts tight enough to prevent slippage.
9. Use CAUTION in working around high speed fans, gas burners, augers and auxiliary conveyors
which can START AUTOMATICALLY.
10. Keep area around air inlet to the fan clear of any obstacles and combustible materials.
11. BEFORE attempting to remove and reinstall any propeller, make sure to read the recommended
procedure listed in the Service Section on Page 42 of the manual.
12. Make sure that capacities of auxiliary conveyors are matched to dryer auger capacities.
13. DO NOT operate in an area where combustible material will be drawn into the fan.
14. The operating and safety recommendations in this manual pertain to the common cereal
grains as indicated. When drying any other grain or products, consult the factory for
additional recommendations.
15. Routinely check for any developing gas plumbing leaks. Check LP vaporizer for contact with
burner vanes.

Use Caution in the Operation of this Equipment
This dryer is designed and manufactured with operator safety in mind. However, the very nature of a grain
dryer having a gas burner, high voltage electrical equipment and high speed rotating parts, presents
hazardstopersonnelwhichcannot becompletely safeguardedagainstwithoutinterfering withthe efficient
operation of the dryer and reasonable access to its components.
Use extreme caution in working around high speed fans, gas-fired heaters, augers and auxiliary
conveyors, which may start without warning when the dryer is operating on automatic control.
Continued safe, dependable operation of automatic equipment depends, to a great degree, upon the owner.
For a safe and dependable drying system, follow the recommendations within the Owner’s Manual and make
it a practice to regularly inspect the unit for any developing problems or unsafe conditions.
Take special note of the Safety Precautions on Page 6 before attempting to operate the dryer.

Dryer Pre-Season Checks
Before staring the drying for the first time in a drying season, perform the following checks. If any of the
checks fail to produce the stated result, the customer should consult your dealer.
Do not attempt to use the dryer unless all the pre-start checks have been successfully completed.
Inspect the Metering Rolls
Open all metering roll access doors and inspect each compartment for any bolts, nuts or other foreign
material that may cause possible jamming of the metering rolls.
Check Control Panel Switches
Before applying electrical power to the dryer, be sure that all switches on the dryer control panel are in the
OFF position.
Electrical Power
Turn ON the electrical power supply to the dryer, set all circuit breakers to ON, including the safety
disconnect handle mounted on front of the dryer power panel.
Control Power Switch
TurntheControlPower switch toON. At thispoint,the controllerwilllock outallother dryer functions.Once
the Boot Screen appears, touch the Start button and the dryer will perform a safety circuit check. If a fault
is found, the cause will be displayed on the main screen. If all circuits are safe, the controller will supply
power to the electronic fuel shut off valve (Maxon), if so equipped and the Start switch will illuminate,
indicating that the dryer is ready to be started.
Start Switch
Push the Start switch and all the selector switches on the control panel will be activated.
Fuel Check
If using LP gas, makesure the tankhas plenty offuel and that thetank does not havea regulator mounted
on the liquid line. Slowly open the main fuel supply valve at the tank. Then, open the electronic shut off
valve (Maxon valve), if so equipped, or open the manual shut off valve on the dryer to allow fuel flow to
the dryer.
If using natural gas, make sure an adequate supply is available. Turn ON the valve along the supply line. Then,
open the electronic shut off valve (Maxon valve). Inspect all gas lines and connections for possible leaks.
Before attempting to operate the dryer, make sure all safety shields are in place,
all bottoms are cleaned out and rear access doors are closed and all personnel
are clear of the dryer.
Any gas leaks must be fixed immediately.

Load Auger
With the grain supply shut off, quickly flip the Load Auger switch to MANUAL and see if the load auger
rotates clockwise as viewed from the drive end, or counterclockwise if the dryer is a front loadmodel. If the
wet grain supply auxiliary is wired to the dryer, it should also rotate in the correct direction at this time.
Turn the Load Auger switch to the AUTO position. The top auger and wet grain supply auxiliary should
run for 8 minutes and then the dryer will shutdown and the safety shutdown message (out of grain
warning) will be displayed. Press the Stop button to reset the panel, then press the Start button.
Unload Auto Operation
To check Auto operation, place the Unload switch in the AUTO position. Push then turn the meter roll
dial to a setting of 500 andtouch ACCEPT/EXIT to start the meter roll rotation. The bottomauger should
rotate counterclockwise as viewed from the driveend. The meter roll drive motor should rotate clockwise
as viewed from the drive end of the gear box. If the dry grain take away auxiliary is wired to the dryer, it
should start and rotate in the proper direction.
Unload Manual Operation
To check Manual operation, move the Unload switch in the MANUAL position. Push then turn the meter
roll dial to a setting of 500 and touch ACCEPT/EXIT to start the meter roll rotation. The bottom auger
should rotate counterclockwise as viewed from the drive end. The meter roll drive motor should rotate
clockwise as viewed from the drive end of the gear box. If the dry grain take away auxiliary is wired to
the dryer, it should start and rotate in the proper direction.
Meter Roll Operation
When the meter rolls are set to maximum (1000), the meter roll speed should be 17.5 RPM for 8'' (20 cm)
discharge augers. Make sure the drive chain tension is properly adjusted and all sections of the meter rolls
rotate. Turn the Unload switch OFF after these checksare complete. The bottom auger will continue to run
for 60 seconds (the default clean out delay setting) after the switch is turned OFF to allow for clean out.
NOTE: Due to the nature of the DC drive motor used on the meter rolls, it is possible for the brushes
inside the motor to become corroded if the dryer has not been operated for several months. This
will cause the meter rolls not to function. To fix this problem, use a rubber mallet or a piece of
wood to tap the DC drive motor. The shock is usually sufficient to restart the motor and metering
rolls. You should not have any more problems with this during the rest of the drying season.
Fan Switches
Briefly turn each Fan switch to ON and observe the fan rotation. The fan should run counterclockwise.
Sometimes,on3phasemodels, allmotorsrunbackwards.Theycaneasilybe reversedbyinterchanging
two of the three power supply wires. Reverse the two (2) outside wires, L1 and L3 and leave the middle
one in the same position.
NOTE: The bottom fan on the dryer is always referred to as fan 1.
All power should be switched OFF and locked out before attempting to reverse
the connections.

Burner Safety
To check the burner safety function, first make sure the main gas valve is OFF. Turn the Fan switch ON and
allow the fan to start. Turn the Heater switch ON for that fan. The dryer will shutdown after 20 seconds. The
safety message, “Ignition Failure Fan #” will appear. Reset the dryer and repeat for the other fan/heater(s).
Burner Test Fire
To perform this test, the dryer must be full of grain. If the dryer is empty, the air switch must be disabled.
To disable, touch the Setup button at the bottom of theDefault Operation Screen. When the Setup Screen
appears, touch the Diagnostics button to display the System Diagnostics. To disable the air switch, select
the Disable Testing button in the air switch box of the System Diagnostics Screen. The Vision computer
will then display a prompt asking if you wish to disable the air switch. Choose YES to continue. Once the
air switches are disabled, the Fan switches on the switch panel will illuminate and the fan/heaters on the
display animation will change to blue, indicating that “airflow” is simulated.
There is only a 5 minutes period after the dryer is turned on that the air switches can be disabled. After
5 minutes, the air switches cannot be disabled and any air switches that are disabled will return to the
enabled state causing an airflow shutdown if the dryer is empty. To restart the 5 minutes test period, the
dryer must be shutdown and restarted. The 5 minutes test period starts when the Control Power switch is
turned ON.
Test fire each burner by starting the fan. Turn on the fuel supply, then turn the Burner switch to ON. The
burner should ignite after a short purge delay of approximately 10 seconds. Gas pressure should be shown
on the gauge. At this time adjust the plenum setpoint to 200°F (93°C), causing the burner to operate on
High-Fire. Observe the gas pressure on the gauge andlower the plenum setpoint until it causes the burner
to cycle into Low-Fire. When the plenum temperature setpoint is met, the gas pressure should show a
noticeable drop, indicating that the cycle solenoid is closed and the burner is being supplied with less gas
through the cycle solenoid bypass port. At this time set the High-Fire and Low-Fire pressure settings. Use
the pressure regulator (for LP models) or the supply line ball valve (for natural gas models) for High-Fire
and the adjustment screw on the cycle solenoid for Low-Fire. The computer should cycle the burners
between high and low, approximately 1 to 3 times per minute.
Use only the amount of pressure required to obtain the desired temperature.
Approximate settings are shown below:
If the burner remains on High-Fire and does not cycle, increase the regulator setting on the propane
models, or the supply valve on the natural gas models, in order to reach the plenum setpoint. If the burner
remains in Low-Fire and does not cycle, slightly decrease gas pressure with the Low-Fire adjustment
screw on the cycle solenoid. If the gas pressure is decreased too much, a popping or fluttering sound will
be heard. This popping and fluttering should not be allowed to continue or damage to the burner will occur.
Be sure to adjust the low pressure needle valve anytime the high pressure regulator is adjusted. Repeat
the test for each fan/heater unit.
LP Gas Natural Gas
High-Fire 6-15 PSI (41-102 kPa) High-Fire 6-10 PSI (41-69 kPa)
Low-Fire 2-6 PSI (14-41 kPa) Low-Fire 1-3 PSI (7-20 kPa)

Dryer Shutdown
To shutdown the dryer:
1. Close the fuel supply valve at the tank or valve along the fuel line.
2. If the burner is operating, let the dryer run out of fuel and it will shutdown automatically due to loss
of flame.
3. Close the fuel valve at the dryer and press the Stop button.
4. Turn OFF the control power.
5. Turn OFF the safety disconnect handle on the front of the power box and turn OFF the main power
to the dryer.
Emergency
In case of emergency, push the Emergency Stop button. This will interrupt power to the control panel and
the fan; burner and all augers will stop immediately.
