Replacing the Regeneration Heater
(W600 - 1000) (continued)
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 removal, wrap the cut insulation sleeve around the new heater tube and
secure it with duct tape.
10 Make sure the cable end of the heater tube is to the bottom then secure
the new heater tube to the mounting bracket with a hose clamp.
11 Connect the hoses to the top and bottom of the heater tube and secure
them with hose clamps.
12 Connect the high temperature switch wires to the quick disconnects near
the heater tube.
13 Route the heater power cable into the control cabinet and connect the
leads to the original locations on the terminal block. Refer to the wiring
diagram for specific connection information.
14 Replace the side panel of the dryer.
15 Measure the resistance from each leg of the heater tube to the others and
from each leg to ground. There should be +/- 5% resistance variation
between all 3 legs, and high resistance from each leg to ground.
16 Connect the dryer to power and turn it on. Verify that the regeneration
temperature achieves the setpoint.
