1. Safety
Working at Heights
Whilst the equipment has been designed to operate primarily at ground level, at some stages during the
life cycle it will be necessary to operate at heights. For this reason the equipment has been provided with
access ladders, platforms and walkways. These have been designed to recognized safety standards to
minimize the risk to health and safety to operators and technicians working on them. In addition attention
should be paid to the following safety requirements.
1. The ladders, platforms and walkways are for use by competent and trained personnel only. NEVER
allow children or members of the general public to gain access to the equipment, its ladders or
access platforms.
2. Where the equipment is sited in an unsecured location, access must be restricted by use of security
fencing and lockable gates.
3. Lower sections of ladders on the equipment should be fitted with a lockable safety gate, to prevent
unauthorized access.
4. Ensure any hot surfaces have had adequate time to cool before working on or in the equipment.
This may require running the equipment fans only to cool off external screens and internal
burner components.
5. The equipment should be OFF and all power LOCKED OFF before work on or in the equipment.
Ensure the power isolator is OFF and LOCKED and TAGGED to prevent inadvertent re-start.
This must include all equipment attached to the dryer/bin on which you are working. (See Figure 1A.)
Figure 1A
6. Ensure the fuel supply is OFF and LOCKED. (See Figure 1B.)

7. NEVER attach lifting equipment to ladders or platforms.
8. When working on the equipment, NEVER go outside the safety rails provided.
9. NEVER walk on the roof of the equipment.
10. Do not work at heights during high winds, heavy rain, snow, ice or storm.
The majority of routine cleaning and service can be carried out from the service platforms provided.
However in exceptional circumstances it may be necessary to access other parts of the equipment. In
particular, in the rare event that access is required to repair or r eplace the g rain level switches. On th ese
occasions additional access and safety equipment may be required. Wherever possible we recommend
the use of powered access lift platforms or ‘cherry pickers’. In exceptional circumstances access may
require the use of safety harness. Such work must only be carried out b y specialist technicians trained and
qualified in working at heights and only after a complete risk assessment has been carried out and safe
working methods established.
Entering Grain Dryers
Wherever possible it is recommended not to enter grain dryers. However, if you have to enter the, observe
the following minimum
precautions:
1. NEVER
2. Make sure you are aware of all the possible hazards
3. Complete a risk assessment
4. You may need to complete a permit to work

chamber or surrounding the outside of the dryer.
Precautions to Reduce Risk of Fire
Whilst the dryer has been designed to minimize the risk of ignition of combustible dust and dirt, this can
only be ensured by regular inspection and cleaning. At least every five (5) days.
1. Refer to Page 10 for required precautions before entering the dryer. The dryer must be locked out
and tagged at the main power and fuel supply before entering.
2. Open the dryer access hatches and check for any significant build-up of dust or particles of grain.
3. Using an industrial vacuum cleaner, clean the plenum. Do not use compressed air.
4. Check inside other dryer accesses and clean as required.
5. Check all personnel are out of the dryer, close and lock all accesses before re-starting drying.
6. This procedure may be carried out more regularly in conditions of extreme dust and dirt.
Exercise greater caution when drying highly flammable grains and seeds. For example rapeseed, can ola,
linseed, sunflower and milo.
All grain and seed must be whole (minimal cracked or crushed), clean and dust free.
Dry at low temperatures (< 40°C).
Avoid dust and chaff being drawn into the fan and heater.
Keep the fan, heater, drying plenum and ducts clean at all times.
In the event of a fire (or suspected fire).
•Shut down the entire dryer.
•Turn OFF fuel at the tank or supply valve.
•Shut off and lock electrical power.
•Evacuate the area.
•Call the fire department.
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
hazards to personnel which cannot be completely safeguarded against withou t interfering with the efficient
operation of the dryer and reasonable access to its components.
Use extreme caution at all times when working on or around the dryer.
Continued safe, dependable operation of automatic equipment depends, to a great degree, upon the
owner. 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.

Page 58
8. Dryer Start-Up and Operation
How the Advanced Moisture Control Works
1. Wet and dry moisture and grain temperature are continually monitored.
2. Control action is mainly based on the dry sensor.
3. Grain flow is increased or decreased to maintain the required dry moisture.
4. The wet sensor and the column grain temperature sensor are intended to detect moisture spikes
coming into the dryer so that the moisture controller can react ahead of time. If the wet sensor detects
a jump of moisture coming into the dryer, the controller will slow down the unload speed immediately.
This process is gradual, to prevent over-drying.
5. MANUAL control is use at the start of drying to allow the controller to gather sufficient information to
adequately control.
IMPORTANT: Once drying has commenced DO NOT make frequent adjustments to drying parameters.
This will cause control instabilities and result in over or under drying. Allow the controller to
manage the dryer.
BEFORE SERVICING THE DRYER. Turn OFF and LOCK electrical power at the
MAIN DISCONNECT. Turn off fuel supply.
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.
PNEG-1797CE CE Approved T-Series Tower Dryer65
Page 66
10. Service
In Case of Fire
1. Hit emergency stop.
2. Shut off power.
3. Shut off fuel.
4. Do not try to cool a fire by running fan(s).
5. Never run grain from the dryer into the elevator or storage if a fire is known or suspected.
6. Locate the area of the fire.
7. If safe to do so, tackle the fire with a suitable extinguisher. Check for secondary fires.
8. Emergency discharge slide gates at the bottom of each column as well as easy access gates located
near the hopper discharge area permit fast dumping of each individual grain column.
9. If in doubt call the fire department.
End of Season Service
1. Always empty the dryer at the end of the drying season.
2. Shut off electrical power and lock.
3. Shut off gas/fuel supply and lock.
4. Clean out the plenum roof grain cushion and remove any grain that may be hanging up on the
plenum roof.
5. Make sure the grain exchangers are clean.
6. Clean out the hopper that divides the heat section from the cooling section.
7. Clean the cooling chamber floor.
8. Remove all grain and trash from the metering drum floor. This grain can be raked out by hand by
opening the slide gates located in the hopper bottom of the dryer.
9. Make sure gas supply is shut off to the dryer.
10. Open the gas train drain valve located on the bottom of the gas train.
11. Cover the burner with a tarpaulin or plastic.
