Pre-Seasonal Inspection and Service
1. Inspect control panels for loose wires, rodent damage and accumulated foreign material. Clean and
repair as required.
2. Lubricate the blowers, motors and metering system as per lubrication table on Page 68 .
3. Check blower belts tension.
4. Inspect and clean the burner. Check that holes in the stainless steel air mixing plates are clear.
Clean if required.
5. Check connections to flame rod and spark plug. Clean or replace if necessary.
6. Check gas train drain valve and drain any accumulated water. Close before dryer operation.
7. Check the discharge area is cleaned of stalks and old grain. Inspect the sweeps for excessive wear.
8. Remove covers from burner.
IMPORTANT: The covers to the discharge sections on the tower dryers must be in place and clamped
down at all times when the dryer is in operation. If the cover is off during operation, the
vacuum created by the blowers will suck foreign matter from the discharge area and deposit
it in the heat section of the dryer plugging the inside screens of the dryer also creating a
fire hazard.
See pre-season check list on Page 67 .
Seasonal Inspection and Service
1. Follow lubrication guides in the lubrication table on Page 68 .
2. Keep the cooling chamber floor clear of dust and dirt. Check each day before starting drying. Failure
to do so could result in a fire. Dirt can be swept into the unload systems.
3. Keep the heat section clear of dust or dirt. Check the hopper divider that separates the heat section
from the cooling section to ensure that it remains clean and open.
4. Check the grain discharge area on the dryer. On ‘Accutrol’ sweep dryers check the sweeps for trash
or stalk build ups that could be obstructing grain flow.
5. If undried grain is left in the dryer for more than a week during the drying season, inspect the plenum
roof to make sure that there is no wet grain sticking to the roof that could restrict grain flow. When
the dryer is re-started make sure that all grain columns are evenly unloading.
6. If the perforated outer sheets on the dryer have become excessively dirty, they may need to be
washed off to prevent inhibited airflow.
WARNING
BEFORE SERVICING THE DRYER. Turn OFF and LOCK electrical power at the
MAIN DISCONNECT. Turn off fuel supply.
