4. Don’t use the ceramic heater under the following conditions: quick heat up, a quick cool down, and uneven heat distribution. Because on the above conditions open circuit. racking problems may happen. Please be careful of heat shock besides other situations that are not mentioned here such as incomplete contact with a metal part that will also cause uneven heat distribution.
5. Don’t put excess strength to Ni-wire and brazing area. If Ni wires were bent many times, power concentration points will become brittle. Crack even breakage may happen. If pulled Ni wires with excess power, the brazing area will be peeled off.

B. Setting notice of ceramic heater.

1. Turn off the power supply so as not to reach the ignition point of utilizing. Components by using thermal fuse and etc. It has the possibility of making fire caused by rapid rising temperature on the heater due to the factor of breaking the sensor and etc. For the sake of each customer’s responsibility, please make some countermeasures such as turning off the power in case of extreme rapid raising the temperature.
