How do novices check and use freezers?

check whether the freezer can be used normally and whether it is damaged during delivery. How should it be checked? 1. When the freezer is first used, it needs to be unloaded, because the new machines all need a running-in process, and a large amount will be added after a period of operation, which can prolong the service life of the freezer. 2. After other inspections are completed, the power supply should be switched on after 2 hours of rest, because it takes a certain amount of time for the and cooling oil in the commercial freezer to return to the compressor, and whether there is abnormal sound in the commercial freezer. 3. Power-on check. When the power is turned on, the freezer can immediately start working and operate. After being powered on for a while, the heat dissipation temperature on the back of the freezer will rise and there will be obvious freezing feeling inside. 4. When buying a freezer, pay attention to whether the position of the freezer is reasonable and whether it is convenient for the freezer to dissipate heat. But also need to check the power supply before use, whether it is grounded, whether it is a dedicated line. 5. Before using, the user should carefully read the attached product manual and check the various components of the commercial freezer. 6, the freezer should use single-phase three-hole socket, separate wiring. Pay attention to protect the insulation layer of the power cord, do not press the wire, and do not change or lengthen the power cord at will.
