How to use the cooling circulator correctly?

        The application of cooling circulators  is more and more extensive, so everyone should know about the use of cooling circulators, but many of the precautions are easy for others to ignore. Let's take a closer look.
1. Liquid medium should be added before use. Liquid medium generally uses more than 95% alcohol, and the liquid medium can not be lower than 20mm of the work board.
2, the use of working power should be determined according to the model (technical parameter column), the power supply should be greater than or equal to the total power of the instrument, the power supply must have a good "grounding" device (Note: low temperature coolant circulating pump 380v voltage instrument behind There is a grounding lead on the lower left screw).
3. The instrument should be placed in a dry and ventilated place with a distance of 400 mm from the obstacle on the back and sides.
4. The low-temperature coolant circulating pump is counted down. When the timing is over, the SV window displays the word “end”. At this time, the compressor stops working, and the work can be restarted at the set time or by re-opening the “total power supply”.
