SAFETY PRECAUTIONS
READ THESE INSTRUCTIONS
BEFORE OPERATION AND SERVICE
SAVE FOR FUTURE REFERENCE
1. Read and understand the operating manual before trying to operate the dryer.
2000 Autoflow
Use Caution in the
Operation of this
Equipment
2. Power supply should be OFF for service of electrical components. Use
CAUTION in checking voltage or other procedures requiring power to be ON.
3. Check for gas leaks at all gas pipe connections. If any leaks are detected, do not operate the dryer. Shut down and repair before further operation.
4. Never attempt to operate the dryer by jumping or otherwise bypassing any safety devices on the unit.
5. Set pressure regulator to avoid excessive gas pressure applied to burner during ignition and when burner is in operation. Do not exceed maximum recommended drying temperature.
6. Keep the dryer clean. Do not allow fine material to accumulate in the plenum or drying chamber.
The design and manufacture of this dryer is directed toward operator safety. However, the very nature of a grain dryer having a gas burner, high voltage electrical 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 reasonable access to components.
Use extreme caution in working around high speed fans, gas-fired heaters, augers and auxiliary conveyors, which may start without warning when the dryer is operating on automatic control.
6
7. Use CAUTION in working around high speed fans, gas burners, augers and auxiliary conveyors which START AUTOMATICALLY.
8. Do not operate in any area where combustible material will be drawn into the fan.
KEEP THE DRYER CLEAN
DO NOT ALLOW FINE
MATERIAL TO ACCUMULATE
IN THE PLENUM CHAMBER
OR SURROUNDING THE
OUTSIDE OF THE DRYER
9. Before attempting to remove and reinstall any propellor, make certain to read the recommended procedure listed within the servicing section of the manual.
10. Clean grain is easier to dry. Fine material increases resistance to airflow and requires removal of extra moisture.
Proper Use of Product
This product is intended for the use of drying small grains only.
Any other use is a misuse of the product!
This product has sharp edges! These sharp edges may cause serious injury. To avoid injury handle sharp edges with caution and use proper protective clothing and equipment at all times.
Guards are removed for illustrati on purposes only. All guards must be in place before and during operation.
Continued safe, dependable operation of automatic equipment depends, to a great degree, upon the owner. For a safe and dependable drying system, follow the recommendations within this manual, and make it a practice to regularly inspect the operation of the unit for any developing problems or unsafe conditions.
Take special note of the safety precautions listed above before attempting to operate the dryer.

The three (3) Drying Chamber Rotary
Switches are used by the series 2000 Autoflow to monitor the location of grain in the Drying Chamber.
The rotary switch with the shortest shaft extension is the Drying Chamber Overflow Rotary Switch. It is used as a safety in the event the Chamber High
Level Rotary Switch fails. The rotary switch with the longest extension is the Drying Chamber Low
Level Rotary Switch. It is used to inform the computer when the peak has been covered with grain so the drying process can begin; and, will shut down if the drying chamber empties unexpectedly. The third rotary switch is the Drying Chamber High
Level Rotary Switch. It is used to inform the dryer when the drying chamber is full so loading can stop.
When mounting the Drying Chamber
Rotary Switches some foresight is needed. The
Drying Chamber Rotary Switches should be located in close proximity to one another to lessen the amount of conduit and wiring required. The rotary switches should also be mounted so that they are
INSTALLATION located in an area of the drying chamber that fills evenly with the rest of the drying chamber. The component placement on page 9 shows the placement of the Drying Chamber Rotary Switches in relation to the Fill System #1 transport auger/ downspout.
The rotary switches should NOT be located in a part of the drying chamber that fills unevenly with the rest of the drying chamber. If the area of the drying chamber where the rotary switches are located fills faster that the rest of the drying chamber the drying chamber will not fill to capacity and uneven drying will result. If the area of the drying chamber where the rotary switches are located fills slower than the rest of the drying chamber an overflow situation may occur.
It is very critical that the drying chamber fill evenly and that the grain falls from Fill System
#1 directly onto the perforated cone in the drying chamber.

Top Dry dryers have internal vaporizers, and they are designed to operate on liquid draw from the supply tank. Avoid using propane supply tanks that have been used for vapor draw for long periods of time. When using liquid draw systems any moisture that may be present in tanks or lines may freeze when the system is used in cold weather. To avoid this situation, purge the system with methanol. 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. Because the vaporizer coil may need to be adjusted during operation flexible hose suitable for
LPs should be used for the final field connection.
See the “Fuel Systems and Rec-
Liquid Propane (LP)
ommendations Chart” for liquid propane to determine the correct size line to run from the tank to the dryer. Have a qualified gas service person inspect the installation to be sure that everything is installed according to local codes and ordinances.
After installation is complete check all connections for leaks with liquid detergent or comparable. Wear rubber gloves and eye protection.
Avoid contact with liquid propane. DO NOT USE FLAME FOR LEAK
TESTING.

This dryer is designed to operate on natural gas. Natural gas units have a larger orifice to accommodate lower pressures sometimes found with natural gas and do not have vaporizer coils like liquid propane units. A regulated pressure of 10 PSI minimum, 30 PSI maximum must be provided at the field connection point on the fan and heater unit, with gas available in sufficient volume to maintain the operating pressure.
See the “Fuel Systems and

Power Supply
An adequate power supply and proper wiring are important factors for maximum performance and long life of the dryer. Electrical service must be adequate enough to prevent low voltage damage to motors and control circuits (see Electrical Load Information on page 40). In
220V 1 ph and 220V 3 ph systems a separate neutral wire is required for the 120V heater circuit, and should be connected to terminal #1 in the master heater. Do not run in conduit with motor power lines.
Transformer and Wiring Voltage Drop
It is necessary to know the distance from the unit to the available transformer, and the horsepower of your fan unit. Advise the service representative of your local power supplier that an additional load will be placed on the line.
Each fan motor should be wired through a fused or circuit breaker disconnect switch. Check on KVA rating of transformers, considering total horsepower 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, and after motor is running at full speed it should be within 8% of normal voltage. Check Electrical Load Information for HP ratings and maximum amp loads to properly size wire and fusing elements. Standard electrical safety practices and codes should be used. (Refer to National Electrical Code
Standard Handbook by National Fire Protection Association).
Machine to Earth Grounding
It is very important that a Machine To Earth Ground
Rod be installed at the fan. This is true even if there is a ground at the pole 15 feet away. Place the ground rod that comes standard, within 8 feet 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. The proper grounding will provide additional safety in case of any short and will ensure long life of all circuit
ELECTRICAL POWER SUPPLY boards, and the ignition system. The ground rod must be in accordance with local requirements.
Proper Installation of Ground Rod
It is not recommended that the rod be driven into dry ground.
Follow these instructions for proper installation:
1.Dig a hole large enough to hold 1 to 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. The water will work its way down the hole, making it possible to work the rod completely into the ground. This method of installing the rod gives a good conductive bond with the surrounding soil.
5. Connect the bare, copper ground wire to the rod with the proper ground rod clamp. See
Figure 12.
6. Connect the bare copper ground wire to the fan control boxes with a grounding lug.
7. Ground wire must not have any breaks or splices.
Dig a hole large enough to hold 1 or 2 gallons of water. Work the ground rod into the earth until it is completely in the ground.

The Fill System Control Box houses the starter (s) for the fill system(s) that load grain into the Top Dry Autoflow Unit and for the aeration fan. DO NOT run the control wires for the Fill System Control Box in the same conduit used for the power wires for the fill system and aeration fan motors. To wire the Fill System
Control to the Autoflow Control Box do the following.
1) Run ten (10) control wires from the
Autoflow Control Box to the Fill System
Control Box.
2) Connect the wires as shown in figure 24.

Master to Slave Interconnect
A slave fan/heater unit can be added to operate in unison with the master fan/heater unit.
The interconnect between the master and slave fan/heater units remains the same regardless of the type or presence of a control center. To wire a slave fan/heater unit to a master fan/ heater unit do the following:
NOTE: Do NOT use solid wire for interconnection.
NOTE: A shielded 16 gauge cable is recommended for use on the network connections.
The network connections for this configuration are attached to terminals number 8 and 9 in the master unit and terminals number 3 and
4 in the slave unit. Ground each end of the shielded cable to the housing. A shielded 16 gauge 2 wire cable can be purchased from GSI.
Part # WR-16 / 2S.
1. Run four (4) 16ga MTW type wires from the master fan/heater unit to the slave fan/ heater unit.
2. Connect the wires as shown in figure #26.

Slave to Slave Interconnect
A second slave fan/heater unit can be added to operate in unison with the master fan/heater unit and another slave fan/heater unit. This would create a three fan unit. The interconnect between the first slave fan/heater unit and the second slave fan/heater unit remains the same regardless of the type or presence of a control center. To wire a second slave fan/heater unit to another slave fan/heater unit do the following:
NOTE: Do NOT use solid wire for interconnection.
1. Run four (4) 16ga MTW type wires from the first slave fan/heater unit to the second slave fan/heater unit.
2. Connect the wires as shown in figure
#27.
NOTE: A shielded 16 gauge cable is recommended for use on the network connections. The network connections for this configuration are attached to terminals number 7 and 8 in slave #1 and terminals number 3 and 4 in slave #2.
