Precautions

1. Indoor temperature: 5-32℃, relative humidity 80%/22℃.
2. The distance from the ground is >10cm. The altitude is below 2000m.
3. It takes 6 hours to decrease from +20℃ to -80℃.
4. Strong acid and corrosive samples should not be frozen.
5. Frequently check the sealing strip of the outer door.
6. Landing on all four feet is stable and level.
7. When there is a power failure prompt, press the stop beeping button.
8. The general refrigeration temperature is set at 60℃
9. The power supply voltage of 220v (AC) must be stable, and the power supply current must be at least 15A (AC) or more.
10. In the event of a power failure, the power switch and battery switch at the back of the refrigerator must be turned off. When the normal power supply is restored, the power switch at the back of the refrigerator must be turned on, and then the battery switch will be turned on.
11. Note that heat dissipation is very important to the refrigerator. It is necessary to maintain indoor ventilation and a good heat dissipation environment, and the ambient temperature cannot exceed 30C.
12. In summer, adjust the set temperature to -70℃, and pay attention to the usual setting not too low.
13. Don't open the door too big when accessing the samples, and keep the access time as short as possible.
14. Note that the samples that are frequently accessed should be placed on the upper second layer, and the samples that need to be stored for a long time infrequently accessed should be placed on the lower second layer, so as to ensure that the air-conditioning is not excessively lost when the door is opened, and the temperature will not rise too fast.
15. Note that the filter must be cleaned once a month (first use a vacuum cleaner, rinse with water after suction, and finally dry and reset). The internal condenser must be vacuumed every two months to suck the dust on it.
16. Do not use force to open the door when the door is locked to avoid the door lock from being damaged.
17. To defrost, only cut off the power supply of the refrigerator and open the door. When the ice and frost begin to melt, a clean and absorbent cloth must be placed on each layer of the refrigerator to absorb and wipe the water (note that there will be a lot of water).
