Do you know all these points about the use of low-temperature refrigerators? Ultra-low temperature refrigerators are often called ultra-low temperature freezers, ultra-low temperature storage boxes,
etc.

Correctly avoiding the operation precautions of ultra-low temperature refrigerators will help prolong the life and use of ultra-low temperature refrigerators
.

The following points should be paid attention to when using the ultra-low temperature refrigerator: 1.
Strong acid and corrosive items should not be frozen
.

2.
Working environment: Indoor temperature: 5-32℃, relative humidity 80%/22℃
.

3.
The distance from the ground is more than 10cm and the altitude is below 2000m
.

4.
When the ultra-low temperature refrigerator is powered off, press the stop beeping button
.

5.
The general refrigeration temperature is set at -60℃
.

6.
Always check the sealing tape of the outer door of the ultra-low temperature refrigerator
.

7.
The four feet are stable and the ground is level
.

8.
Paying attention to heat dissipation is very important for ultra-low temperature refrigerators.
It is necessary to maintain indoor ventilation and a good heat dissipation environment, and the ambient temperature cannot exceed 30 degrees
.

9.
Adjust the set temperature to -70℃ in summer, and pay attention not to set it too low
.

10.
The power supply voltage should be stable at 220v (AC), and the power supply current should be at least 15A (AC)
.

11.
When a power failure occurs, turn off the power switch and battery switch behind the ultra-low temperature refrigerator.
When the normal power supply is restored, first turn on the power switch behind the ultra-low temperature refrigerator, and then turn on the battery switch
.

12.
Pay attention to cleaning the filter screen once a month (suck it with a vacuum cleaner first, rinse it with water after suction, dry it and reset it), and use a vacuum cleaner to suck the dust on the internal condenser every two months
.

13.
Do not force the door when the door is locked to avoid damage to the door lock
.

14.
When accessing samples, the door should not be opened too much, and the access time should be as short as possible
.

15.
Note that the samples that need to be accessed frequently should be placed on the upper two floors, and the samples that need to be stored for a long time infrequently should be placed on the lower two floors, so as to ensure that the air-conditioning will not be excessively lost when the door is opened, and the temperature will not rise too fast
.

16.
To defrost, you can only cut off the power of the refrigerator and open the door.
When the ice and frost begin to melt, put a clean and absorbent cloth on each layer of the refrigerator to absorb and wipe off the water (note that there will be a lot of water)
.

 The above is the relevant introduction about the use of low-temperature refrigerators.
I believe that everyone has a corresponding understanding of this after reading, and everyone can use it as a reference.
I hope it will be helpful to you
