Probe domestic switch needle KG-300K, with a head diameter of 3.0mm, is a normally open switch needle.

MOS power IC full range available for various applications.

LC03-3.3 SOP8 TVS Static Protection at 3.3V for reliable circuit protection.

1. The vacuum box housing must be properly grounded to ensure safe operation and prevent electrical hazards.

2. When the vacuum box is not in continuous use, always close the vacuum valve first before turning off the pump power supply. This prevents oil from being sucked back into the vacuum chamber.

3. Before placing any items inside, remove any torn or damaged materials. For flammable substances, make sure they are cooled below their ignition point to avoid oxidation and potential combustion.

4. The vacuum box does not have an explosion-proof device. Therefore, it is strictly prohibited to place explosive materials inside for drying purposes.

5. It's recommended to install a filter between the vacuum box and the pump to prevent moisture or foreign particles from entering the pump and causing damage.

6. Avoid opening the side door unnecessarily to protect the internal electrical components and maintain system integrity.

7. This equipment should be connected to a dedicated air switch for enhanced safety and control.

8. Ensure that all electrical insulation is intact and that the casing is properly grounded or connected to zero to prevent electric shocks.

9. Regularly replace the vacuum pump oil to maintain optimal performance and extend the life of the pump.

10. When removing processed items, especially flammable ones, allow them to cool below the ignition point before exposing them to air to prevent combustion due to oxidation.

11. Since this equipment lacks an explosion-proof mechanism, never place explosive materials inside the vacuum box during the drying process.

12. Always have a trained operator present when using the electric vacuum drying oven to ensure proper handling and operation.

13. If the oven will not be used for an extended period, remove all items from the working chamber and clean it thoroughly to maintain a dry environment.

14. If any abnormal behavior occurs, stop the equipment immediately and inspect it. If the issue cannot be resolved, contact the technical support team of the purchasing company for assistance.

15. Keep the vacuum box clean at all times. Wipe the door glass with a soft cloth only—avoid using chemical solvents that could scratch or damage the surface.

16. If the vacuum box is not in use for a long time, apply a thin layer of neutral grease or petroleum jelly on plated parts to prevent corrosion. Cover it with a plastic dust cover to protect against moisture and dust.
