Use a small high-low temperature cycle integrated machine, or after transportation, or power outages (including power outages) for more than 10 hours, before use (or before power-on use again)
.
It can be used only after the machine is qualified
.
1.
The small high and low temperature cycle integrated machine can be used for at least a certain period of time before it can be powered
on.
2.
It is strictly forbidden to experiment with too many relatively hot materials, otherwise the compressor will not stop for a long time, the temperature will not drop and the compressor will be easily burned, and the temperature will be lowered in steps until the required low temperature
.
3.
The alarm is activated by the alarm: When the alarm is activated by the alarm, it is usually possible to check whether there is a problem with the power supply or whether the plug is pulled out of the socket,
etc.
4.
Insufficient cooling: check whether there is frost on the surface of the evaporator of the equipment; whether the back of the equipment box is in contact with the wall
.
5.
Land on all four feet smoothly and level.
When there is a power failure prompt, press the stop beeping button
.
6.
The power supply voltage should be stable at 220v.
When a power failure occurs, the power switch must be turned off, and the power switch must be turned on when the normal power supply is restored
.
7.
Pay attention to the importance of heat dissipation to the equipment, and maintain the ventilation and good heat dissipation environment where the equipment is located
.
8.
Note that the filter is cleaned once a month, and the internal condenser must be cleaned of dust every month
.
The maintenance and maintenance of the small integrated high and low temperature cycle machine is particularly important for prolonging its life and normal use.
If the temperature control is not accurate, it is often damaged, which will have a great impact on the experimental results, thereby affecting the normal progress of research work
.
