3. Installation
PNEG-634 2000 Top Dry Fan/Heater 15
Multi-Grain Temperature Sensor
1. Remove the two (2) wires attached to the grain temperature sensor connected to terminal #22 and
terminal #23 in the fan control box.
2. Mount the four (4) grain temperature sensor brackets evenly around the drying chamber on outside
leveling band posts. (See Figure 3E on Page 13.)
3. Mount the bracket with bin bolts so the sensor is 17-1/2" above the floor sheet rib.
4. Wire tie the cords so they feed up the leveling band post and across the top leveling band.
5. Route the cords through the space between the roof and the top sidewall sheet. There should be
enough on all temperature sensor brackets to exit the drying chamber at the same place.
6. Route the cords into the junction box after the junction box has been mounted to the bin.
7. Wire the four (4) temperature sensors. (See Figure 3G.)
