Replacing the Process Heaters
This refers only to replacing the heater elements in the heater booster located on the drying
hopper(s). For replacing the heaters inside of your dryer, refer to the other operation and
installation manual(s) accompanying this manual.
Before replacing any heaters in your Central Drying System, power must be turned off and
disconnected. If your dryer was running recently, allow the heaters ample time to cool
down. Failure to allow cool down may cause serious injury due to excessive temperatures.

Remove the screws that are bolting the cover onto the NEMA Box
2.
Remove the Screws and washers bolting the heater to the box frame
3.
Remove any wiring that is connected to the heater and make note of their orientation
on the heater element. Try and place the heater back into the box in the exact
position that it was taken out.
4.
Slide out the heater element and remove the gasket placed between the element and
the box frame. Set the gasket aside for reuse or replace if needed.
5.
After checking the new heater element for proper functionality, slide it back into the
box frame and rewire as required.
