2. When the ultra-low temperature storage box is running for a long time, frost is easy to accumulate at the door seal, the cabinet opening and the inner side wall of the box. If the frost layer is too thick, it will affect the sealing performance and refrigeration performance. Please use a defrosting scoop to defrost regularly and wipe it with a dry cloth. .

　　 3. Clean the inner and outer surfaces of the storage box with a non-corrosive neutral cleaning agent. After cleaning, wipe with a dry cloth.

　　 4. Use a soft brush or vacuum cleaner to regularly remove the dust on the condenser to maintain a good condensation effect;

　　5. When the storage box is out of service, unplug the power plug, clean it according to the above method, put it in a plastic bag after natural drying, and place it in a well-ventilated place.
