The following low temperature freezer manufacturers will talk about what should be paid attention to during the operation of ultra-low temperature freezers?

1. Ensure the ambient temperature. The working environment temperature of the ultra-low temperature freezer should be below 30 ° C, and the surrounding ventilation should be good. Too high temperature or poor ventilation can easily cause equipment overload and damage.

2. Regularly organize the heat exhaust filter (once every two months). If the filter is not sorted out for a long time, the dust will block the mesh, resulting in poor heat exhaust, resulting in damage to the heat exhaust motor and thus damage to the compressor. Please check the instruction manual for the sorting method.

3. Regularly organize the freezing at the door seal of the ultra-low temperature freezer. The door seal is not strict, and the thermal insulation effect is severely reduced, which simply leads to damage to the compressor due to long-term overload operation.

4. When storing samples, the door should not be opened too much, and the access speed should be as short as possible.

5. Note that the samples that need to be stored frequently should be placed on the upper second floor, and the samples that need to be stored infrequently for long-term storage should be placed on the lower second floor, which can ensure that the air conditioner is not excessively consumed when opening the door, and the temperature will not rise too fast.

6. Note that the filter screen must be cleaned once a month (first vacuum cleaner, after suction, initialize with water, then dry and reset), and the internal cooler must vacuum the dust on it every two months.

7. Do not open the ultra-low temperature freezer compressor with force on the premise that the door is locked to avoid the door lock being damaged.

8. To defrost, you can only disconnect the power supply of the ultra-low temperature freezer and open the door. When the ice and frost begin to melt, you must put a clean and easily absorbent cloth in each layer of the ultra-low temperature freezer to absorb and wipe the water clean (note that there will be a lot of water).
