7. Electrical Wiring
The dryer modules are shipped with the wiring as complete as possible within each module. The
following wiring must be completed in the field when mating the dryer body with the fan-heater module.
1. Load Motor - The rear-fill load auger motor conduit is shipped attached to the fan-heater module
roof. Remove the conduit shipping ties and attach the conduit junction box to the upper right hand
side of the front dryer panel using (4) self-tapping screws. Route the flex conduit to the unload
motor and wire motor for the appropriate supply voltage. Attach the Fill Switch box to the Fill
Paddle shaft. Connect the SJO cord to orange and yellow wires inside the Top Auger Conduit
junction box.
2. Unload Motor - The conduit for the unload motor is found tied to the rear fan-heater frame channel
under the module. Route the flex conduit to the unload motor and wire motor for the appropriate
supply voltage.
3. SCR Motor - The conduit for the SCR motor is found tied to the rear fan-heater frame channel under
the module. Route the flex conduit to the SCR motor and wire motor.
4. Sensors - Find the flex conduit tied to the right side of the dryer body module and route to the Upper
Control Box and connect wires to the terminal strip as shown in Figure 4M.
5. Maxon Valve and Fuel Manifold - Route these two conduit to the Upper Control Box and connect
the Maxon valve wires to the lower terminal strip at the gray and white terminals labeled for the
Maxon valve. Connect fuel manifold wire to the upper terminal strip as shown in Figure 4M.
6. Liquid Solenoid Valve and Vapor Hi-Limit - If the dryer is equipped with a LP vaporizer the
Vaporizer Conduit must be assembled to the Vapor Hi-Limit Thermostat and the Liquid Solenoid
Valve. Connect the thermostat and valve in series and route the conduit to the upper control box.
Connect wire to the appropriate terminals as shown in Figure 4M.
