1. Read and understand the operating manual before trying to operate
the dryer.
2. Never operate the dryer while the guards are removed.
3. Power supply should be OFF for service of electrical compo
nents. Use CAUTION in checking voltage or other procedures re
quiring power to be ON.
4. Check for gas leaks at all gas pipe connections. If any leaks
are detected, do not operate dryer. Shut down and repair be
fore further operation.
5. Never attempt to operate the dryer by jumping or otherwise bypass
ing any safety devices on the unit.
6. Set pressure regulator to avoid excessive gas pressure applied to
burner during ignition and
when burner is in operation. See chart
foroperating procedures. Do not exceed maxi
mumrecommended
drying temperature.
7. Keep the dryer clean. Do not allow fine material to accumulate
in the plenum chamber.
8.
Keep auger drive belts tight enough to prevent slippage.
9. Use CAUTION in working around high speed fans, gas burners,
augersand auxiliary conveyors which STARTAUTOMATICALLY.
10. Donot operateinany areawherecombustible materialwillbe drawn

11. Beforeattemptingtoremoveandreinstallanypropellor,makecertain
toreadtherecommendedprocedurelistedwithintheservicingsection
of the manual.
12. Be certain that capacities of auxiliary conveyors are matched to
dryer auger capacities.
13. Clean grain is easier to dry. Fine material increases resistance to
airflow and requires removal of extra moisture.
Use Caution in the
Operation of this
Equipment
The design and manufacture of
this dryer is directed toward op-
erator safety. However, the very
nature of a grain dryer having a
gas burner, high voltage electri-
cal equipment and high speed
rotating parts, does present a
hazard to personnel, which can
not be completely safeguarded
against, without interfering with
efficient operation and reason-
able access to components.
Use extreme caution in
workingaround high speed fans,
gas fired heaters, augers and
auxiliary conveyors, which may
start without warning when the
dryer is operating on automatic
control.
READ THESE INSTRUCTIONS
BEFORE OPERATION AND SERVICE
SAVE FOR FUTURE REFERENCE
Continued safe, dependable op-
eration of automatic equipment
depends, to a great degree, upon
the owner. For a safe and de-
pendable drying system, follow
therecommendationswithinthis
manual, and make it a practice
to regularly inspect the opera-
tion of the unit for any develop-
ing problems or unsafe condi-
tions.
Take special note of the
safety precautions listed above
before attempting to operate the
dryer.

troller. When the dryer is restarted the timers will
continue timing down. The timers will return to their
initial settings by pressing the stop button.
In both the auto and manual position the load auger
will operate if the dryer is low on grain and will auto-
matically shut off when the dryer is full. In the auto
position only, the dryer will shut down after a preset
period of time set on the out of grain timer, if grain
flow is interrupted to the dryer. The switch will light
whenever the load auger is operating.
Note: If the load auxiliary motor connections are
being utilized in the dryer control panel, this switch will
also control the operation of the auxiliary equipment.
This is used to select the operation of the fill auger.

SERIES 2000 BATCH DRYER DRYER PRE START CHECKS
To check the batch operation, locate the white junc-
tion box in the back of the dryer, under the rear ac-
cess door, and remove the cover exposing the mer-
cury switch. Position the switches on the control
panel as follows:
Load - Manual position, to avoid the out of grain
warning in the auto position
Fan - Auto position
Burner - Auto position
Unload - Auto position
Turn on the control power and wait until the display
settles on the plenum tempature. At this point the
timers may be adjusted. Press the start button. The
load switch should light up indicating the loading
process. If it is not lit check the back of the load
mercury switch to see that it is installed properly.
This mercury switch is shipped to you mounted on
the front of the dryer in a white box with a black
cord going to the junction box with the outside
light attached. This switch must be installed on
the load auger to work.
Go to the back of the dryer and reverse the
mercury switch in the clip so the leads are on the
right side. This simulates the presence of grain.

verse the unload mercury switch, so the leads are
coming from the left side of the switch. This will
tell the dryer all the grain has been emptied and
will start the process at the beginning of the batch
cycle again.
Be sure to return the rear unload mercury
switch 90 degrees counterclockwise to
simulate the dryer being completely full
of grain. At this point, the fan should start

the manual shut off valve to allow fuel flow
to the dryer.
3. The dryer should already be filled with
grain. Turn the load auger switch 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 control the length of the dry time using
only the HI and LO temperature setting pro
grammed into the system, turn the moisture

Seasonal Inspection and Service
The dryer is made of weather resistant material, and
is designed to require a minimum of service. How-
ever,eachseasonwe recommend the following items
be checked before the unit is used, and any dam-
aged or questionable parts replaced. These checks
will help eliminate possible failures, and assure de-
pendable operation of the equipment.
1. Shut off electrical power. Open power box and
controlbox,and inspectfor moisture,rodentdamage
or accumulated foreign material. Remove any
foreign material present. Inspect and tighten
any loose terminal connections. Replace any
damaged or deteriorated wiring.
2. Check propellor for freedom of rotation and uni
formtip clearance.It shouldalso beinspectedfor dirt
and grain dust, especially inside the hub.Any addi-
tional weight can seriously effect the balance, and
result inharmful vibrations and a short bearing life.
3. Check propellor for free play. Any side play is an
indication of defective motor bearings, which
should bereplaced to preventa complete motor fail
ure. Make sure motor mount bolts are tight.
4. Motor bearings should be lubricated periodically, de
pending on operating conditions. Under normal
usage it is desirable to have the motor cleaned,
Ifthe motor is equipped with an alemite fitting, clean
the tip of the fitting and apply grease gun. Use 1 or
2 full strokes on motors in NEMA 215 frame and
smaller. Use 2 to 3 strokes on NEMA 254 through
NEMA 365 frame. Use 3 to 4 strokes on NEMA
404framesandlarger. On motors having drain plugs,
remove drain plug and operate motor for 20 min-
utes before replacing drain plug. On motors
equipped with slotted head grease screw, remove
screw and apply grease tube to hole. Insert 2 to 3
inch length of grease string into each hole on mo-
tors in NEMA frame and smaller. Insert 3 to 5 inch
length on larger motors. On motors having grease
drain plugs, remove plug and operate motor for 20
minutes before replacing drain plug.
Lube Procedures
* The bearings have been lubricated at the factory, thus no lubrication should be added before start up.

Continuous Normal Applications
Seasonal Service (motor is idle for 6
months or more)
Continuous high ambient tempera-
tures, dirty or moist locations, high
vibrations or when shaft end gets hot
checked and bearings repacked by an authorized
service station every two to three seasons. If t he
unit is operated continuously through most of the
year, this service should be performed each
year.
Note: If on site bearing relubrication is to be
performed, see lubrication instructions for ball
bearing motors. To keep motor bearings prop
erly lubricated, and dispel any accumulation of
moisture within the windings, the fan and au-
ger motors should be operated for 15 to 30 min-
utes each month.

Note: All of the auger and metering roll bearings are lifetime lubri-
cated and do not require service relubrication.
1. Remove and clean the gas line strainers. Make certain gas valves are
closed and that gas is purged from the system before attempting disas-
sembly.
2. Inspect the collector plate (at the top of the burner casting) and
the burner cup for any accumulation of foreign material. Clean if
required. Foreign material in the burner cup or casting will not
burn out and will impair burner operation.
3. If required, inspect ignitor plug and clean the electrodes. Use an ignition
point file to remove carbon and rust between the electrode surfaces.
Ignitor gap should be about 1/8 inch.
4. Inspect flame sensor for possible damage or poor connections.
Flame sensor wire must be in good condition.
5. Inspect and manually rotate the top auger paddle assembly. The paddle
unit must rotate freely without any indication of sticking or binding.
6. Inspect the top auger and bottom auger drive lines for proper adjust-
ment and condition. Readjust line tension as required.
Note:Alloftheaugerandmeteringrollbearingsarelifetimelubricatedand
do not require service relubrication.
7. Operate dryer clean out le
vers, and checkclean-outhatch
mechanism for proper opera-
tion. With hatch open, in-
spect and remove any
accumulation of dirt, fines
and foreign material from
the bottom auger trough
area.
Note: Do not allow high moisture
material to collect within the
trough area. It may adversely af-
fect metal parts.
8. Inspect entire dryer for loose,
wornor damaged parts. Include
check of auger flighting, me-
tering rolls and other internal
parts. Check that temperature
sensors within air plenum
chamber are secured within
insulated clamps, and do
not chafe on other metal parts.
9. Make sure all dryer guards
and warning decals are se
curely installed.Guardsshould
not interfere withmovingparts.
If guards or warning decals are
missing, contact your dealer
for a free replacement.
10. Test fire the dryer several
weeks ahead of the drying sea
son. Check for possible gas
leaks. See page 15 for burner
test fire.
Remove the Blue Burn Optimizer
Cone and inspect the 1-collector
plate, 2-burner cup, 3-ignitor plug
and electrodes and the 4-flame
sensor on the heater.
