Troubleshooting
Replacing the Heaters
Process Heater Tube
1
Stop the dryer, disconnect the power, and follow proper lockout
procedures.
2 Remove the plastic cover.
3 Disconnect the wiring
harnesses of the defective
process heater. Then
disconnect the hoses from
the top and bottom of the
heater tube.
4 Remove the clamp securing
the heater tube in place then
remove the heater tube from
the dryer.
5 Cut the insulation in a
straight line from end to end
then remove it from the old
heater tube.
6 Compare the markings on the
outside of the process heater
tube to ensure the new one has
the same voltage and kW
ratings as the original heater
tube.
7 Put the insulation on the new heater tube. Use duct tape to hold the seam
together.
8 Secure the new heater tube using the hose clamp removed in Step 4.
9 Connect the hoses to the top and the bottom of the process heater tube.
