6-6 Replacing the Process Heater

Our dehumidifying dryers use Calrod-type heater elements mounted in a heater tube located in the top rear of the cabinet. The wattage of the heater varies with model, voltage, temperature range, etc., but the replacement procedure is the same.

If the process heater is mounted to the hopper, contact the manufacturer for the appropriate replacement procedure.

WARNING!

Disconnect and lock out power before you replace heater elements!

Use the following procedure to replace the process heater:

1.Remove the bolts securing the process heater access cover.

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 bolts 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. Install new heater gaskets and securely tighten all fasteners.

Caution! Heater loops should not touch each other. “Hot Spots” lead to premature heater failure!

7.Reinstall the wires based on the sketch you made earlier.

8.Secure the heater access cover.
