| Always use a vacuum oven with pump in an environment where the relative humidity ≤85% RH, and there is no corrosive gas, strong vibration source, or strong electromagnetic field. Ensure that the outer casing of the vacuum oven dryer is effectively grounded to ensure safe usage. | Tips for Using a Vacuum Oven with Pump |
| The test room of a vacuum oven with pump is not treated with explosion-proof, corrosion-resistant, and other measures. Therefore, do not dry flammable, explosive, or corrosive objects in the test room. If you need to dry an object that releases a corrosive gas, please indicate so in advance so that special corrosion-resistant materials can be used. | |
| The vacuum pump should not run for an extended period. Therefore, when the vacuum degree meets the drying requirements, close the vacuum valve first, then turn off the vacuum pump’s power supply. When the vacuum degree is less than the drying requirements, open the vacuum valve and the vacuum pump’s power supply again to continue vacuuming. | |
| This approach can extend the vacuum pump’s service life. Alternatively, you can use an automatic interlocking device to control the vacuum, which will stop at the required vacuum degree and restart when the vacuum degree falls below the required level. | |
| If the object being dried is damp, it is better to add a filter between the vacuum box and the vacuum pump to prevent damp air from entering the vacuum pump and causing a vacuum pump failure. | |
| If the object being dried changes to lightweight and small volume (in the form of small particles) after drying, it is advised to add a separating mesh to the vacuum port in the test room to prevent dried materials from entering and damaging the vacuum pump (or solenoid valve). | |
| The vacuum oven with pump might have trouble vacuuming after several uses. In such cases, it is necessary to replace the door seal or adjust the door buckle’s extending distance on the box to solve the problem. | |
| Clean the vacuum oven regularly. Do not use chemically reactive solutions to clean the door glass of the vacuum oven. Use a soft cotton cloth to wipe it. Do not use sharp objects to scrape the tempered glass window. | |
| If the vacuum oven dryer is not going to be used for an extended period, wipe the exposed electroplated parts clean, apply neutral grease to them to prevent corrosion, and cover the vacuum oven with a plastic dust cover. Place it in a dry indoor environment to prevent electrical components from becoming damp and affecting usage. | |
| When discontinuous vacuuming is required, you should close the vacuum valve first and then turn off the vacuum pump’s power supply; otherwise, vacuum oil will flow back into the vacuum oven, but a special valve can prevent the vacuum oil from flowing back. | |
| If the humidity of the material being dried in the test room is high, the generated water vapor will affect the vacuum pump’s performance. Therefore, it is recommended to connect a “drying/filter” between the vacuum oven and the vacuum pump. If an inert gas such as nitrogen needs to be added during the drying process, a contract should indicate this, and an intake valve should be added to the vacuum oven with pump. |
