1. The use environment of the sudden jump thermostat should avoid stains and moisture, otherwise it will affect the electrical performance of the product, and the thermostat must be used in a working environment with a relative humidity of ≤ 90% and no contact with corrosive and flammable mediums. For use in wet environments or submerged liquids, a special impermeable seal is required for the thermostat.
2. When the sudden jump thermostat is installed, it is absolutely not allowed to deform the temperature sensing surface (cover), and the top of the cover should not be collapsed or deformed, so as not to affect the temperature and electrical performance of the thermostat;
3. When the sudden jump thermostat is installed, the temperature sensing surface of the thermostat cover should be evenly touched with the temperature control part; When the thermostat adopts contact temperature sensing, it is best to coat a layer of thermal conductive grease on the temperature-sensing surface of the cover, so that there is no gap between the temperature-sensing surface and the temperature-controlled surface, so as to improve the thermal conductivity effect.
4. When the sudden jump thermostat is installed, the terminal of the thermostat should not be bent, and the wiring of the terminal should be in good contact, otherwise the reliability of the electrical contact will be affected. If solder wiring is used, a soldering iron of no more than 60W should be selected, and the soldering time should be controlled within 5 seconds.
5. When selecting the sudden jump thermostat, the temperature selection should be accurate. Due to the influence of various factors such as thermal inertia, conduction, etc., so as to avoid changes in temperature.
