Replacing the Heaters

Regeneration Heater

1 Disconnect and lockout the main power.

2 Gain access to the regeneration heater by removing the right

dryer side panel.

3Open the electrical enclosure door.

4Remove the hose and hose clamp at the bottom of the heater tube.

5Remove the insulation from the heater tube by cutting the insulation in a straight line from top to bottom.

6Remove the small 1/8" (3.18 mm) plastic hose from the hose barb, and remove the hose barb. Save the barb, it will need to be installed in the new heater tube.

7Remove and save the regeneration RTD and fitting. They will be installed in the new heater.

8Reference the wiring diagram and / or trace the wires from the regenera- tion heater tube into the control box. Remove the wires from the relays and terminal strips. Once disconnected, pull the wires from the control box into the dryer housing toward the heater tube.

9Remove the heater tube by twisting the tube counterclockwise. The tube is threaded into the lower bed plate. You may need to use a pipe wrench or chain wrench to remove it.

10Check the ID mark on the side of the heater tube for kW rating and volt- age. The ID mark is on the outside of the tube near the end with the lead wires. Make sure the kW and voltage is the same as the replacement heater.

11Thread the new heater into the lower bed plate. The RTD should be point-

ing directly toward the back of the dryer. Do not over tighten. Hand tighten, ✐ and use a wrench for no more than one turn to get RTD into the correct posi- tion.

Note: When installed the regener- ation heater tube must be oriented so the RTD is directly toward the back of the dryer.
