The dryer is available with an optional transport kit for transporting the unit by truck or tractor. Make certain
to observe the following safety precautions.
1. Recommended towing hitch height is 14"-17''. (See Figure 4A.)
Figure 4A Use a 14"-17'' Towing Hitch Height and a Safety Chain
2. Hitch bolt must be at least 3/4" in diameter and securely fastened with a locking nut, so it will not
come out during travel and the hitch will not bend. (See Figure 4B.)
3. Be sure to minimize vertical hitch play with washers. (See Figure 4B.)
Figure 4B A 3/4'' Hitch Bolt and Washers Fastened with a Locking Nut
at the Bottom of the Hitch
4. Always use a safety chain. (See Figure 4A.)
5. Dryer must be towed empty and in accordance with applicable state or provincial regulations.
NOTE: NEVER tow dryer with grain or any other material inside of it.
6. Recommended tire pressure is 55-60 PSI (cold).
7. Maximum towing speed is 45 miles per hour or the speed limit, whichever is lower.
8. After the first 50 miles and every 200 miles thereafter, check the following:
a. Dryer wheel hub and spindle temperature immediately after stopping. Temperature should not
exceed 150°F. It may be hot to touch, but not melting lubricant.
b. Wheel lug nuts. They are factory torqued at 115 to 120 ft. lbs. Retighten, if required.
When considering the exact location of the dryer, also consider the wet grain supply and dry grain
discharge, as well as the location of storage bins and other grain handling equipment. Do not install
the dryer inside a building or in any other area where not allowed by electrical codes, fuel installation
regulations and/or insurance requirements. Maintain a minimum distance of at least 3' from other structures, otherwise air flow problems may occur. Do not operate in an area where combustible materials
can be drawn into the fans or where load and unload augers can come in contact with power lines.
Foundation
A reinforced concrete pad or similar permanent foundation is recommended for dryer stability.
See Pages 22 and 23 for details.
Supporting the Dryer
The wheels are to be used for transporting the dryer only when empty. Before loading any grain into the
dryer, the frame of the unit on each side must be supported. Place concrete blocks on each side, every
6' of the frame, as well as at the hitch mount location with the hitch removed. The blocks must be able to
support the dryer as well as the additional weight of the grain when full. Use shims to provide uniform, level
support for all blocks. The dryer should be at least 16'' off the pad to allow for clean out and the use of
auxiliary grain handling equipment. The hitch tongue should be removed, but the hitch assembly and the
fan support must be left on during operation; they are not part of the transport tie down assembly.
NOTE: Use a minimum of one support per each 6' of basket length on each side.
Anchor Points
Anchor points may be cast into the concrete slab or the dryer may be tied down by cables and turnbuckles
to anchors installed at the edge of the slab. This helps prevent overturn or lateral movement by wind or
other forces.
Wet/Dry Grain
Wet Grain Supply
A wet grain holding bin provides gravity flow to the dryer or loading conveyor. This conveyor may
be electrically connected to the power circuit provided in the main control box. Initially, the dryer will fill
completely. During drying, the top auger will start and stop as required depending upon the dry grain
discharge rate and grain shrinkage to maintain the dryer fill. If the dryer does not fill within the pre-set
time on the out of grain timer (See Vision Manual for instructions on setting this timer), the dryer
will shutdown.
Dry Grain Removal
The dry grain is normally discharged out of the rear end of the dryer. Front discharge is an optional feature.
A take away system needs to be provided to remove grain from the drying system. This conveyor may be
electrically connected to the power circuit provided in the main control box.
An adequate power supply and proper wiring are important factors for maximum performance and long
life of the dryer. Electrical service must be adequate to prevent low voltage da mage to motors and control
circuits. (See Chapter 5 on Pages 24-36.) Power supply for 1 phase models must include a neutral wire.
Transformers and Wiring Voltage Drop
Advise the service representative of the local power supplier that an additional load will be placed on the
line. Check the KVA rating of transformers, considering total horsepower (HP) load. The power supply
wiring, main switch equipment and transformers must provide adequate motor starting and operating
voltage. Voltage drop during motor starting should not exceed 14% of normal voltage. After motor
is running at full speed, it should be within 8% of normal voltage. Check electrical load information
(See Chapter 5 on Pages 24-36)
Power Supply Disconnect
All dryers are equipped with a power disconnect switch in the power box to permit total power shutdown
before opening the power box door, as required for inspection and service. The power disconnect switch
is located on the power box door for quick shutdown.
for HP ratings and maximum amp loads.
Machine to Earth Grounding
A Machine to Earth Ground Rod must be installed at the dryer. Place the ground rod that co mes standard
within 8' of the dryer and attach it to the dryer control panel with at least a #6 solid, bare, copper ground
wire and the clamp provided. The grounding rod located at the power pole will not provide adequate
grounding for the dryer. Proper grounding will provide additional safety in case of any short and will ensure
long life of all circuit boards, the SCR drive and the ignition system. The ground rod must be in accordance
with local requirements.
All wiring to be done in accordance with the Canadian Electrical Code.
Figure 4C Installation of a ground rod (standard with dryer purchase) specifically
for the grain dryer is necessary for safety and equipment preservation.
Proper Installation of Ground Rod
The rod should not be driven into dry ground. Follow these instructions for proper installation.
1. Dig a hole large enough to hold one to two (2) gallons of water.
2. Fill hole with water.
3. Insert rod through water and “jab” it into the ground.
4. Continue “jabbing” the rod up and down. This allows the water to work its way into the ground,
allowing it to be completely inserted into the ground. This method of installation also assures good
contact with the surrounding soil, thereby making a proper ground.
5. Connect the bare, copper ground wire to the rod with the proper clamp.
6. Connect ground wire to control panel with the ground lug provided in the control box.
7. Ground wire must not have any breaks or splices. Do not use insulated wire for grounding ap plications.
Connecting Auxiliary Conveyors
The auxiliary load and auxiliary unload augers or conveyors can be wired directly to the dryer. Electrical
load information in Chapter 5 on Pages 24-36 shows the maximum horsepower and amps of auxiliaries
that can be wired to the dryer. If an auxiliary motor is larger than recommended, it must be powered from
a source outside the dryer and must use a separate contactor and overload protection device for each
motor. However, the operation of the auxiliaries can be performed by the control panel.
The dryers have internal vaporizers and are designed to operate on liquid draw from the supply tank. The
tank should be 1000 gallons or larger and should not have a regulator mounted to it. The connection to
the dryer should be with a flexible hose designed for LP gas, See Chart on Page 19 for proper size.
Consult your LP gas dealer for proper fittings, connection hose and safety controls required to meet local
standards and to conform with National Fire Protection Association standards. The piping train on the
dryer includes strainer, pressure relief valve, electronic safety shut off valve (on some models) and a
pressure regulator between the vaporizer and burner.
Ammonia Tanks
Do not use tanks which have previously been used for ammonia or fertilizer solutions. These substances
are extremely corrosive and will damage fuel supply and burner parts.
Oil or Water in Tanks
With liquid draw from the supply tank, any water or oil present in the tank may freeze in the pipe train or
controls causing damage. To make sure the tank is free of moisture, it can be purged with methanol.
Avoid tanks which may contain an accumulation of oil or heavy hydrocarbon from long use on a vapor
withdrawal system.
