The door is made of luxurious hollow glass, so the insulation and display effect is better. There is a light at the top of the cabinet to ensure lighting in the cabinet at any time. The main technical parameters of the product climate type N Protection against electric shock I Rated voltage V 220 Rated frequency HZ 50 Storage temperature °C -5-10 Safety Precautions 1. No pharmaceutical products and flammable, corrosive and volatile chemicals can be stored in the cabinet. 2. The floor on which the box is placed should be flat and there should be enough space around the box and be well ventilated away from heat sources. 3. Use a voltage range of 187-242V. If the voltage is unstable, use a voltage regulator above 1000W. Be sure to use a three-pin socket with a reliable ground connection with a conductor cross-sectional area ≥0.75mm2. Do not connect other electrical appliances to the same outlet. Multiple sockets can cause heat. After power off, do not start it again within 5 minutes. 4. Do not use various chemical reagents to clean the cabinet. Please use a soft cloth dipped in neutral soap or detergent to wipe the inside and outside of the box. 5. Transport vertically (not more than 45 degrees incline). Protect the power cord. Stable and well-ventilated. Avoid heat sources to avoid moisture. CZ series seed storage cabinet instructions The temperature in the cabinet can be adjusted by the thermostat. When the knob is rotated clockwise, the temperature in the cabinet gradually decreases (that is, 0 is the compressor stop; 1 is slightly lower temperature; 2-4 is medium and low temperature; 5 is low temperature) On the contrary, the temperature rises. The number on the knob indicates the hot and cold trend and does not indicate the temperature in the cabinet. When the knob is turned to "strong cold" (maximum value), the unit continues to operate. It is most suitable to rotate the temperature knob to 2-4. Note: "Strong cold" continuous operation can not be too long. When the storage cabinet is being transported, the angle of inclination shall not be greater than 45 degrees. Take care to protect the power cord so as not to cause wire wear, electricity leakage and fire. Do not push it quickly on uneven roads so as not to damage the compressor, directional wheels and other systems. . When the storage cabinet is in normal use, please do not move it to avoid affecting the performance and causing damage. Store items gently and gently; do not throw objects into the cabinet so as not to damage the inner wall. There should be a certain spacing between storage items in the cabinet to facilitate the flow of cold air and uniform temperature. To keep it clean, clean it regularly. Before cleaning, unplug the power plug. In order to save electricity, open the door as much as possible to reduce the opening time. When you stop using it, wipe it clean with a soft cloth. Common faults and handling Note: The following phenomena are not faults 1. A slight sound of water is emitted during work. 2, compressor and condenser heat or even hot. 2. If the humidity is high, dewdrops are easily generated on the outside of the cabinet. Dry it with a soft dry cloth in time.
