Replacing the Regeneration Heater
(W1600 - 2400)
1 Stop the dryer, disconnect and lockout the main power.
2 Locate the heater. Open the side panels of the dryer locating the
heater which is secured to the inlet of the desiccant wheel assembly by
hard piping, brackets and clamps. See Installation section entitled, Opening
the dryer doors (W1600-5000).
3 Disconnect the main power leads at the junction box inside the frame
of the dryer.
4 Disconnect the high temperature switch cable at the quick disconnect.
5 To remove the defective regeneration heater tube, loosen the pressure
clamps at the top and bottom of the heater tube connection and slide the
clamp and its silicon gasket back away from the heater tube. W1600-
2400 model dryers lower clamp is attached to a bracket that is mounted
to the desiccant wheel assembly, loosen clamp to remove it from the
bracket. Remove and check the bottom heater hose for loose debris or frag-
ments, these fragments can damage the newly installed heater if not removed.
6 Slide the insulation off the heater tube, or make a cut down the entire
length of the insulation sleeve to aid removal.
7 Compare the markings on the outside of the regeneration heater tube to
ensure the new one has the same voltage and kW ratings as the original
heater tube. This information is on the end nearest the wires.
