6-7 Replacing the Regeneration Heater

The dehumidifying dryers use heater elements located below each desiccant bed.

WARNING!

Disconnect and lock out power before you replace heater elements!

1.Remove the cover plate secured by bolts.

2.Sketch the heater wiring configuration so you can properly re-assemble the heaters.

3.Remove the wiring for the heater being removed or replaced.

4.Remove the bolts securing each heater mounting plate. Slide out the heater.

5.Re-install the new heaters 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!

6.Re-install the wiring based on the sketch you made earlier.

7.Secure the heater access cover.

Changing the Controller Security Level

1.To access protect mode, press and hold the AT button and the Display button for more than one and a half to two (1.5 to 2) seconds.

2.The display should read SECr for security mode. If you press the Display button for short presses you will toggle between (SECr) and (KEYP) for AT protect.

3.With the display reading SECr, set the security levels by the arrow up and down keys. Change the security level to 1 to make changes to the operating parameters. The temperature controller is factory set to Security Level 5, the dew point indicator is factory set to Security Level 3.
