Thermocouple Installation
The Salt Bath kiln uses 3 thermocouples for control. The Over-Temp (high limit) has been installed at the factory. The Chamber and Immersion thermocouples must
be installed.
Over-Temp Thermocouple (#1, lower jack) – Installed at Factory
The purpose of the over-temp thermocouple is to stop the heating process if the kiln chamber exceeds the programmed temperature by 300°F (149°C).
The over-temp thermocouple is installed at the factory and remains in place at all times and is not movable.
The Over-Temp thermocouple is a Type K thermocouple, 1/8”
diameter Inconel sheath, bent at 90°. Supplied with standard
sized male thermocouple connector.
Note the grounding wire connected to the Inconel sheath. This
ground wire will be connected to the control panel.

The Over-Temp thermocouple properly installed.
Note that the over-temp thermocouple is plugged into the #1
thermocouple jack (lower jack). Do not position the over-temp
thermocouple at any other jack than the #1 jack.
The over-temp thermocouple should be inserted into the firing
chamber as far as possible and should remain there.
Note also that the green ground lead for the over-temp
thermocouple is secured to the labeled ground connection
located on the control panel.
