Precautions for showcase

Precautions for showcase

1. After the cabinet is moved, it must be placed securely and stand still for half an hour before it can be powered on. When using a supermarket display cabinet for the first time, let the empty cabinet run for 2 hours before putting the food in the box for storage.

　　2. Once the power supply of the supermarket fresh-keeping cabinet is interrupted, you must wait 5 minutes before allowing the power to be reconnected, otherwise the compressor may burn out.

　　3. The inside and outside of the display cabinet should be clean, wipe off the moisture and mildew in the cabinet, and open the cabinet door to let it fully dry.

　　4. During the use of the showcase, do not open the door too frequently, try to reduce the number of door openings, shorten the opening time, so as to reduce air-conditioning leakage and save electricity

　　5. The four sides of the display cabinet are the suction ports of the condenser, and the area should be kept clean to avoid flying dust and affecting the cooling effect.

　　 6. The temperature of items stored in supermarket display cabinets should not be higher than the ambient temperature.

　　7. The food must be placed in the cabinet in an orderly manner and a certain gap should be maintained between the food to avoid affecting the flow of cold air.

　　 8. The temperature of items stored in supermarket display cabinets should not be higher than the ambient temperature.

　　 9. Take out all the items in the cabinet and pull out the power plug.

　　 10. The display cabinet should be maintained if it is not used for a long time.

If the showcase is used for a long time, it is inevitable that ice will accumulate. If it is usually handled frequently, it is not so laborious when handling it. If it is not handled often, and if you do not pay attention when using it, it will inevitably freeze. produce. Icing will cause the cooling effect of the display cabinet to decrease, because the refrigeration principle of the fresh-keeping cabinet is to compress the refrigerant through the compressor, and the refrigerant is liquefied to generate heat. When it reaches the refrigeration zone, the pressure is reduced, and the refrigerant will vaporize and absorb Heat. If ice builds up on the inner wall of the showcase, it will affect this cycle, so be sure to clean the ice inside the showcase regularly.
