Precaucions per al seu ús:

1. The shell of forn al buit must be effectively grounded to ensure safe use.

2. The vacuum oven shall be used in the environment with relative humidity ≤ 85% RH, no corrosive gas around, no strong vibration source and strong electromagnetic field.

3. No explosion-proof, anti-corrosion and other treatment in vacuum oven workshop, shall not put inflammable, explosive, corrosive gas easy to produce articles for drying.  

4. If the dry goods are wet, a filter can be added between the vacuum oven and the vacuum pump to prevent the wet gas from entering the vacuum pump and causing the vacuum pump failure.

5. After being used for many times, the vacuum oven will not be able to vacuum. At this time, it should be solved by replacing the door seal or adjusting the extension distance of the door buckle on the box. When the drying temperature of the vacuum oven is higher than 200 ℃, slow air leakage will occur. At this time, disassemble the cover plate behind the box, loosen the heater base with an Allen wrench, replace the sealing ring or tighten the heater base.

6. If the rubber stopper of the vent valve is difficult to rotate, it can be lubricated with an appropriate amount of grease inside.

7. Except for maintenance, do not disassemble the left box cover to avoid damaging the electrical control system.

8. The vacuum oven shall be kept clean frequently. Do not wipe the door glass with reactive chemical solution, but with soft cotton cloth.

9. If the vacuum oven is not used for a long time, wipe the exposed electroplated parts and apply neutral grease to prevent corrosion. Put on the plastic film dust cover and place them in a dry room to prevent the electrical components from being damaged by moisture and affect the use.

10. When the vacuum oven does not need continuous air extraction, close the vacuum valve first, and then turn off the power supply of the vacuum pump, otherwise the vacuum pump oil will be poured into the box.
