1. The vacuum box housing must be properly grounded to ensure safe and reliable operation.
2. When the vacuum box is not in continuous use, close the vacuum valve first before turning off the pump power supply. This prevents oil from backflowing into the box.
3. Remove any damaged or torn items before treatment. For flammable materials, cool them below their ignition point before placing them inside to avoid oxidation or combustion reactions.
4. Do not place explosive materials inside the vacuum box, as it lacks an explosion-proof mechanism.
5. It is 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 prevent potential damage to internal electrical components.
7. Ensure that the equipment is connected to a dedicated air switch for safety and stability.
8. Maintain good electrical insulation and ensure that the casing is properly grounded or connected to zero for protection against electric shocks.
9. Regularly replace the vacuum pump oil to maintain optimal performance and prolong the life of the pump.
10. When removing treated items, if they are flammable, make sure they are cooled below their ignition point before exposing them to air to prevent combustion due to oxidation.
11. This equipment does not have an explosion-proof feature, so it should never be used to dry explosive materials.
12. Always have a trained operator present when using the electric vacuum drying oven to ensure proper and safe operation.
13. If the oven is not in use for an extended period, remove all items from the chamber, clean it thoroughly, and keep it dry to prevent corrosion or damage.
14. In case of any abnormal behavior, 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 may cause scratches or chemical reactions.
16. If the vacuum box will not be used for a long time, apply a thin layer of neutral grease or petroleum jelly on plated parts to prevent rust. Cover it with a plastic dust cover to protect it from moisture in the environment.
