Thermocouples
Screw thermocouple in opening (apply never-seize on threads or similar antilocking
paste) and only hand tighten in port. Connect wires and conduit. Connection:
yellow wire to the + side and red wire to the – side.
Space conduit away from hot metal surfaces to prevent melting.
TIP: if controller shows SnSr or similar display the thermocouple is not wired proper,
the red or yellow wire failed, or the inner ceramic element is failed. To confirm the
controller is working shut off power to incinerator, put jumper wire across screws
where red/yellow attach to controller. If a temperature is now shown on the
controller it is good. Fix problem in thermocouple or its wires.
