The first time you use the Xinyi ultra-low temperature cabinet, or the Xinxiao ultra-low temperature cabinet is transported, or the ultra-low temperature cabinet is powered off (including power failure) for more than 10 hours, it must be tested before use (or before power-on). The inspection is qualified.

Welcome to the use of ultra-low temperature storage box:

1. The refrigerator must be allowed to stand for at least 24 hours before it can be energized.

2, empty boxes do not put items, power on, staged the refrigerator first to cool down to -40 degrees, after normal start and stop, then drop to -60 degrees, after normal opening and closing 8 hours, then adjust to -80 degrees, observe the freezer has Normally start and stop for more than 24 hours. Prove that the performance of the freezer is normal.

3. After confirming that the freezer is normal according to operation 2, you can store the items in the freezer. In principle, items of -60 degrees should be stored, no more than 1/3 of the box capacity. If the temperature of the stored items is higher than -60 degrees, the temperature of the freezer should be set at about 3 degrees higher than the temperature of the stored items (ie, if the temperature of the items is 20 degrees, the temperature of the low temperature cabinet is set at 23 degrees) to ensure the freezer. Stopped and has a normal start and stop for more than 8 hours.

4. Prohibition: Therefore, cryogenic storage boxes are all storage equipment. It is strictly forbidden to put too many items that are relatively too hot at one time, which will cause the compressor to stop for a long time, the temperature will not drop and the compressor will be easily burned. Items must be placed in batches, and the temperature is lowered by the step temperature until the required low temperature!

Xin Hao ultra-low temperature refrigerator use precautions

1. Indoor temperature: 5-32 ° C, relative humidity 80% / 22 ° C.

2, from the ground > 10cm. The altitude is below 2000m.

3. It takes 6 hours to reduce from +20 °C to 80 °C.

4. Strong acid and corrosive samples should not be frozen.

5. Always check the closed rubber strip of the outer door.

6, landing four feet steady, level.

7. When there is a power failure prompt, press the stop beep button.

8, the general cooling temperature is set at 60 ° C

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

10. In the event of a power outage, the power switch and battery switch on the back of the refrigerator must be turned off. When the normal power supply is restored, turn the power switch on the back of the refrigerator first, then turn on the battery switch.

11. Note that heat dissipation is very important for the refrigerator. To maintain indoor ventilation and good heat dissipation environment, the ambient temperature should not exceed 30C.

12. In the summer, adjust the set temperature to -70 ° C, and pay attention to the usual setting is not too low.

13. When accessing the sample, the door should not be too large and the access time should be as short as possible.

14. Note that the samples that you need to access frequently should be placed on the top two layers. For samples that need to be stored for long periods of time, please keep them on the second floor. This will ensure that the air 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 suction with a vacuum cleaner, rinse with water, and then dry to reset), the internal condenser must use a vacuum cleaner to suck the dust every two months.

16. Do not use the force to open the door when the door is locked, to prevent the door lock from being damaged.

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