Compared with ordinary refrigerator, ultra-low temperature refrigerator is more expensive and more troublesome to repair. Therefore, we must be cautious and operate in strict accordance with the instructions in daily use. The following are relevant instructions for the use of ultra-low temperature refrigerators.

Instructions for use of ultra low temperature freezer:

1. The ultra low temperature freezer cannot be tilted when it is moved. Lay it flat and move it parallel to avoid the leakage of cold ice oil, which will cause damage to the compressor.

2. For the first time use or after being moved, or encountering a power outage for more than 10 hours, The freezer must be tested after being stationary for 24 hours, and it can be used after confirming that there is no problem.

3. It is recommended that the ultra-low temperature refrigerator be specially equipped with an overcurrent and leakage protection switch, and do not share a power socket with other devices.

4. The low-temperature refrigerator must be placed in a ventilated and dry indoor environment. The indoor temperature cannot exceed 30 °C. When taking items from the refrigerator, please wear antifreeze gloves to avoid frostbite.

5. Do not use glass containers or other containers that are not resistant to low temperature to hold items that need to be frozen, otherwise the container may burst.

6. It is strictly forbidden to put volatile, flammable and explosive dangerous items into the medical refrigerator freezer.

7. When cleaning the refrigerator, just wipe it with a soft cloth. Do not directly rinse it with water, otherwise it may leak electricity.

8. Do not put too many items with relatively high temperature in it at one time. Put them in batches or after reducing the temperature by the quick-freezing equipment. Putting them in at one time may cause the compressor to be damaged without shutting down for a long time.
