Replacing the Process/Regeneration Heater 
The dehumidifying dryers utilize a single-phase Calrod-type heater element.  This heater 
element is mounted in the center compartment in the desiccant beds. Although the 
replacement procedure is the same for each heater, the wattage varies by model, voltage, 
temperature range, etc. 

Disconnect and lock out power before you replace heater elements!
