TopDry Series 2000 Autoflow
Linear Actuator
Turn the Dump switch on the Autoflow control box to the “MANUAL OPEN” position. Use a tape measure
to measure the stroke on the linear actuator. The stroke should be between 16" and 18". If the stroke on
the actuator is not 16" to 18" the actuator should be adjusted. Make sure that all pulleys and cables are
move freely when the actuator is moving. With the actuator extended enter the storage chamber. View
each dump chute individually. Make sure that each dump chute opened completely when the actuator
extended. If a dump chute does not open completely the double nuts on the bolt that the chutes hinge on
need to be loosened. The dump chutes should hinge smoothly. After the chutes have been inspected turn
the Dump switch on the Autoflow control box to the “AUTO” position and press the Stop switch. The chutes
should raise.
Power Start Button
Before the dryer start button is pushed make sure there is grain in the wet supply tank. If there is no grain
in the wet supply tank, the dryer will not start. Push the dryer start button. The screen should no longer be
flashing “Stopped”.
Fuel Check
If using LP gas, make sure the tank has plenty of fuel. If using natural gas, make sure an adequate supply
is available. If using LP gas, slowly open the main fuel supply valve at the tank. If using natural gas, turn
ON the valve along the supply line. Then open the ball valve on the fan heater unit(s). Inspect all gas lines
and connections for possible leaks. Any gas leaks need to be fixed immediately.
Fan
Make sure that all Toggle switches on the fan and heater units are ON. Bump the Fan switch on the
Autoflow control box and observe the fan rotation. The fan should run counterclockwise. Sometimes on
3 phase models the motor will run backwards. This can easily be reversed by first turning OFF the power
at the main disconnect, then interchanging any two (2) of the three (3) power supply wires coming into the
motor starter in the fan control box. Reverse the two (2) outside wires, L1 and L3 and leave the middle one
in the same position.
Aeration Fan
Bump the aeration Fan switch on the Autoflow control box and observe the aeration fan rotation.
The aeration fan should run counterclockwise. Sometimes on three (3) phase models the motor will run
backwards. This can easily be reversed by first turning OFF the power at the main disconnect, then
interchanging any two (2) of the three (3) power supply wires coming into the motor starter in the fill system
control box. Reverse the two (2) outside wires, L1 and L3 and leave the middle one in the same position.
