What should I pay attention to during the operation of the ultra-low temperature freezer?
2022-07-28
The following low-temperature freezer manufacturers to talk about ultra-low temperature freezer operation process need to pay attention to what?
1. Ensure the ambient temperature. The working environment temperature of the ultra-low temperature freezer should be below 30°C and the surrounding area should be well ventilated. Too high temperature or poor ventilation are easy to produce equipment overload operation and damage.
2. Regularly arrange the heat removal filter screen (once every two months). If the filter screen is not cleaned for a long time, dust will block the mesh, resulting in poor heat removal, resulting in damage to the heat removal motor and thus damage to the compressor. Please check the instructions for finishing methods.
3. Regularly arrange the freezing at the door seal of the ultra-low temperature freezer. The door seal is not strict, the heat preservation effect is severely reduced, and the compressor is simply damaged 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 samples to be stored frequently should be placed on the upper second floor, and samples to be stored infrequently for a long time should be placed on the lower second floor, so as to ensure that the air conditioner will not be excessively consumed and the temperature will not rise too fast when opening the door.
6. Note that the filter screen must be cleaned once a month (first use a vacuum cleaner to suck it, then wash it with water, and then dry and reset it). The internal cooler must use a vacuum cleaner to suck the dust on it every two months.
7. Do not force the door to open the ultra-low temperature freezer compressor under the premise of locking the door 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 clean and absorbent cloth on each layer of the ultra-low temperature freezer to absorb and wipe the water clean (note that there will be a lot of water).
