Precautions for Use

• Before putting items into the equipment, confirm that the temperature in the cabinet has reached the set temperature, and then put the items inbatches. Do not put in items for more than 1/3 of the volume of the refrigerator at a time to prevent its temperature from rising too much.
• The displayed temperature of the equipment is the temperature at the temperature sensor in the cabinet. When the equipment just starts to run, the displayed temperature is somewhat different from the actual temperature at the center of the equipment. However, after the equipment enters a stable status, the displayed temperature will gradually approach the actual value.
• The refrigerator is designed with a testing hole so that the test line inside the refrigerator can be led out for testing. After leading out the test line, be sure to re-plug the testing hole with thermal insulation material. Otherwise, the temperature inside the refrigerator may not reach the set value, causing condensation around the outside of the through-hole.
• Please use diluted neutral cleaner to clean the equipment. Do not use brushes, acid, gasoline, soap powder, polish or hot water to clean the equipment; otherwise, the painted surface and plastic/rubber parts may be damaged. Special care must be taken not to use volatile solvents such as gasoline to wipe plastic/rubber parts.
• Cut off the power when the equipment is going to be left unused for a long time.
• Try to reduce the opening time of the door each time when you take or put items to avoid large fluctuations in temperature and humidity inside the refrigerator.
• After the door is opened, the temperature inside the refrigerator will rise sharply for a short time, which is normal, and will recover within 1 hour after the door is closed.
• In a high-temperature and high-humidity environment, condensation may occur on the glass door, which is a normal phenomenon and does not affect the storage temperature in the refrigerator. If condensation occurs, please improve the ventilation conditions as soon as possible and reduce the ambient temperature.
