Mounting method
In case of sensing heat directly from the heat source, place the thermal protector to touch itfs opposite surface of gUCHIYAh printed surface to the heat source.
*In case of sensing convection heat or heat emission,
please contact Uchiya.
The condition of sensing heat differ case by case.
