Replacing the Regeneration Heater
(D3200 - 5000) (continued)
6 Loosen the lower clamps that secure the tubing to the dryer bracket. Remove the
regeneration manifold and the tubing that is attached to the bottom. Then remove the
tubing from the regeneration blower outlet and check for loose particles within the tub-
ing, clean as necessary. Reverse this procedure to reinstall the tubing.
7 Slide the insulation off the heater tube(s), or make a cut down the entire length of
the insulation sleeve to aid removal.
8 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.
9 Slide the original insulation over the new heater, or if the insulation was cut for re-
moval, wrap the cut insulation sleeve around the new heater tube and secure it with
heat tape.
10 Make sure the cable end of the new heater tube is to the bottom, then reconnect
the hoses to the top and bottom of the heater tube and resecure with pressure clamps
that were removed in Step 5.
11 Connect the high temperature switch cable to the quick disconnect.
12 Route the heater power wires into the junction box and connect them to the sup-
ply leads from the control box. Refer to the wiring diagram for specific connection
information.
13 To ensure all connections are correct, measure the resistance as in Step 3. You
should measure the readings as noted for a good heater.
14 Close the side panel of the dryer.
15 Connect the dryer to power and turn it on. Verify the regeneration temperature
achieves the setpoint.
