OPERATING PRECAUTIONS
• Routinely check the drying plenum for accumu-
lation of combustible materials. Begin by
checking two times per day. If no significant
accumulations are found, extend the inspection
period to once a day. Clean any accumulations
from the plenum walls and floor as required.
• Be sure that plenum cleanout doors are firmly
snapped closed before operating dryer. An
open cleanout door, when vacuum cooling, will
accelerate the deposit of combustible materials
in the heating zone, increasing the risk of fires.
• Adjust reclaiming air vacuum, on vacuum cool
dryers, according to instructions on page 14,
”Adjusting Dryer Airflow.” Excess cooling vac-
uum can accelerate the deposit of combustible
materials in the heating zone, increasing risk of
fires.
• Vacuum reclaiming should not be used when
drying volatile or dirty crops such as milo or
sunflower seeds. Use pressure cool configura-
tion.
• Routinely check each grain column for grain
movement, both visually and by feeling the
exhaust air temperature of each column. Slow
moving columns will become much hotter than
other columns. Operating with restricted
columns will reduce the accuracy of the mois-
ture control, reduce drying capacity, and can
increase the possibility of a dryer fire. Plugged
columns should be drained to remove obstruc-
tions or accumulation of fines.
1. Read and understand the operation manual
before attempting to operate the unit.
2. Keep ALL guards, safety decals, and safety
devices in place. Never operate dryer while
guards are removed.
3. Keep visitors, children and untrained personnel
away from dryer at all times.
4. Never attempt to operate the dryer by jumping
or otherwise bypassing any safety devices on
the unit.
5. Always set the main power supply disconnect
switch to OFF and lock it in the OFF position
using a padlock before performing any service
or maintenance work on the dryer or the auxil-
iary conveyor equipment.
6. Before attempting to remove and reinstall the
propeller, make certain to read recommended
procedure listed within the SERVICING sec-
tion of the manual.
7. Keep the dryer and wet holding equipment
CLEAN. Do not allow fine material to accumu-
late. See Warning below.
8. Set pressure regulator to avoid excessive gas
pressure applied to a burner during ignition and
when burner is in operation. See Table 2-1 for
operating gas pressures. Do not exceed max-
imum recommended drying temperatures.
9. Do not operate the dryer if any gas leak is
detected. Shut down and repair before further
operation.
10. Clean grain is safer and easier to dry. Fine
material can be highly combustible, and it also
increases resistance to airflow and requires
removal of extra moisture.
11. Use CAUTION in working around high-speed
fans, gas burners, augers, and auxiliary con-
veyors which start automatically.
12. Be certain that capacities of auxiliary convey-
ors 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 addi-
tional recommendations.
15. Routinely check for any developing gas
plumbing leaks. Check LP vaporizer for con-
tact with burner vanes.
Warning! Dryer Must Be Kept Clean and Airflows
Properly Adjusted for Safe Operation.
