1. The enclosure of the vacuum chamber must be effectively grounded to ensure safe use.
2. When the vacuum box does not need continuous pumping, the vacuum valve should be closed first, and then the power supply of the vacuum pump should be closed, otherwise the vacuum pump oil should be poured back into the box.
3. Take out the disposed objects and tear them. If the disposed inflammable materials are processed, they must be cooled to below the burning point before they can be put into the air to avoid the oxidation reaction causing combustion.
4, vacuum box without explosion-proof device, do not put explosives dry.
5, between the vacuum box and the vacuum pump, it is best to cross the filter to prevent the wet body from entering the vacuum pump.
6, when necessary, do not disassemble the side door at will, so as not to damage the electrical system.
7, the equipment should be equipped with dedicated air switch.
8, electrical insulation is intact, the equipment casing must have reliable protection grounding or protection of zero.
9, vacuum pump should often replace vacuum pump oil.
10. When taking out the processed articles, if the processed inflammable articles are processed, they must be cooled to below the burning point before they can be put into the air to avoid the oxidation reaction causing combustion.
11. The equipment has no explosion-proof device. No explosive materials can be dried.
12, when the electric heating vacuum drying box is used, there must be someone to take care of it to ensure the normal operation of the equipment.
13. When the electrothermal vacuum drying box is not used for a long time, the articles in the workroom should be taken out and wiped clean to keep the equipment dry.
14. If abnormal phenomena occur in the electrothermal vacuum drying box, it should be checked and repaired in time. If the failure can not be accurately judged, it should contact the technical department of the purchasing company.
