Important Guidelines
1
If you are upgrading from a K-type to an S-type
thermocouple, you must reset your controller to the
correct thermocouple type. Otherwise your kiln will
overfire! See next page.
2
The thermocouple is fragile. Handle with care. Do
NOT cut or bend the thermocouple.
3
Use only thermocouple-to-controller lead wires de-
signed for the S-type thermocouple: one black and one
red covered with green outer insulation.
4
Follow color polarity between the thermocouple,
lead wires, and the terminals on the controller.
5
The thermocouple lead wires must not touch the
hot kiln case.
6
Even though they are protected by insulation, ther-
mocouple lead wires are sensitive to electromagnetic
interference. Inside the kiln switch box, position the
thermocouple wires away from other wires. Never let a
thermocouple wire wrap around other wires.
7
Be sure the thermocouple wire ends are separated
where the insulation has been stripped. If bare ends
touch, the thermocouple will not work properly.
8
The S-type thermocouple must protrude at least ½”
- ¾” into the firing chamber.
Installing the Thermocouple
1
Read the guidelines in the left column. Then UNPLUG/dis-
connect the kiln from the power.
2
Remove the screws on the sides of the switch box that hold it to
the kiln. Gently lift the box away from the kiln. Prop the switch
box, if necessary, to prevent straining the wires attached to the ele-
ments.
3
You will see an oval-shaped
c e r a m i c c o n n e c t i o n bl o c k
fastened to the outside of the fir-
ing chamber wall. Remove the 2
screws that fasten the connection
block to the kiln. Pull the old ther-
mocouple from its firebrick hole.
If your kiln has a thermocouple
protection tube, leave it in place.

Installing the
S-Type
Thermocouple
Thermocouple screws must be tight. Observe polarity of wire colors at both the ceramic block and back of controller.
