Dear Customer:
Paragon kilns have proven to be very de-
pendable. However, as with all mechanical de-
vices, kilns do occasionally need maintenance.
We have packed this guide with information
from the minds of our top engineers and tech-
nicians. If you are ever under deadline to get
your kiln running, you will be glad you had this
guide.
If your local dealer does not have a repair
technician, feel free to call the Paragon factory
with questions. But first, try to find the answer
in this trouble shooter. This is usually faster
than a phone inquiry. When calling, please have
in front of you the information on your kiln's
electrical data plate. You will find this on the
side of the kiln switch box.
Please have all of the information from you kiln's electrical
data plate in front of you before calling us.
Make a record of all your firings. Include
firing time, temperature, witness cones, and
firing results. These records will be a valuable
trouble-shooting aid. Firing record blanks are
available from Paragon.
The controller is easy to remove from the
switch box. It is held in place with four screws.
Before removing, please disconnect the power
from the kiln. Certain components on the back
of the controller can be damaged if they touch a
grounded object while the kiln is plugged in.
Please follow the diagrams on page one
carefully when connecting wires to the control-
ler. Attaching input wires to output terminals
can damage the controller.
Most of the error messages shown in this
manual do not apply to the DTC 100 series.
Periodically we hold an in-plant kiln main-
tenance seminar in Mesquite, Texas. Call for
the next scheduled dates.
