Procedures
1. Remove the four (4) 10-32 button head screws securing the
process heater access cover using a 1/8” Allen wrench.
2. Sketch the heater wiring configuration so you can properly re-
wire the heater.
3. Remove the wires to the heater plate assembly being removed or
replaced.
4. Remove the two (2) 4-40 screws securing the heater plate
assembly, and slide out the assembly.
5. Remove the heater from the mounting plate by removing the
large brass nuts and washers.
6. Re-install the heater and heater plate assemblies in reverse order.
