What's the reason why the vacuum volume of the vacuum precooler hasn't decreased after pressing the start button?
When the user presses the start button on the touch screen (or the start button on the panel), the device runs normally. After a few minutes, if the vacuum level does not decrease, the following aspects should be checked:
1. Check if the door of the equipment has been closed in place
2. Carefully observe the '' in the door frame; O" Is the circle installed properly
3. Check if the vacuum pump is operating normally and if all valves in the vacuum pipeline are tightened
Solution: Close the door tightly and lock the door latch. If it is not in place, please install it correctly into the "O" groove.
