| Pay attention to the safety of electricity｜Vacuum drying oven for power transformer | |
| When wiring, pay attention to the linearity of the label on the line. | |
| Do not connect the wrong linearity｜Vacuum Oven Instructions | |
| The color of the line is different depending on the manufacturer, so as to avoid unnecessary circuit accidents. |
| Do not place the unit in direct sunlight or excessive ambient temperature. The optimum ambient temperature is 5 °C – 25 °C, and the optimum ambient humidity is 35%-65% relative humidity. | Maintenance Notice |
| To maintain a long-term, well-ventilated location, make sure that the voltage is correct before use. Only apply the voltage indicated on the machine to avoid excessive electrical current and cause the wire to escape. | |
| Do not place in a damp place, do not rinse directly with water to prevent leakage. | |
| It is forbidden to place flammable and explosive products around the machine, and it is forbidden to put inflammable and explosive products into the oven to prevent accidents. | |
| Please carefully put the items into the laboratory vacuum drying oven, close the door, check whether it is closed, after baking or testing the knot speed, please open the door at a safe temperature to take the product, and pay attention to open the door at high temperature, and burn the face with hot air. | |
| After the vacuum oven with pump is finished or after the product is baked, the contents of the room should be removed to avoid adverse effects on other products when the machine will rework next time. Keep the inner and outer boxes clean and dry for a long time, and do not use them for a long time. Turn on the main power supply. | |
| Always listen to the sound of the vacuum chamber oven running when it is normal. If you hear an abnormal sound, stop watching, If the operator can’t solve the problem, please call our after-sales service department. Let our company’s after-sales personnel provide guidance or on-site maintenance. | |
| After the laboratory vacuum ovens sets the required temperature value, it is not easy to modify the set value during the startup process. The unrelated person or the operator does not need to operate the temperature control instrument to prevent the built-in factory parameters of the instrument. Cause the temperature control instrument to not work properly. | |
| Pay attention to check the vacuum pump oil, which is normally 2/3 or the scale position of the oil level window. | |

● The pirani vucuum gauge will control the upper and lower limits of pressure. Example: 9.5 E 1 means 9.5^1 = 95 Pa
● Example: Teach you set Max 100 Pa, Min 120 Pa for a Vacuum testing work.
● First, You need to set 100 Pa first, 1.0 E 2 means 100 Pa,
● 1.2 E 2 means 120 Pa, When the pressure down to 120 Pa, Then the vacuum pump will start to work and keep the inner testing room vacuum with 100 Pa.
