Maintenance and maintenance of ultra-low temperature explosion-proof refrigerator
1. Refrigerator cooling is not sufficient
Check the evaporator surface for frost, whether the refrigerator door is switched too frequently, if the back of the refrigerator touches the wall, and if there are too many items on the surface.
2. Clean once a month to ensure its cleanliness

In the actual use of the process, there will be many other problems, such problem stoic solution needs to accumulate experience to remove obstacles, so that ultra-low temperature explosion-proof refrigerator to achieve zui good working conditions.
4. Alarm stoa
When an alarm is activated by an alarm, it can usually be viewed through the following.
to see if there is a problem with the power supply or if the plug is pulled out of the socket;
