1. After the test is completed, the temperature should be set at 70℃. After baking for 2 hours, cut off the power supply and dry the moisture in the studio to keep the box clean and dry.；
2. When the equipment is not in use for a long time, the equipment should be powered on regularly, generally once a month, and the power-on time is not less than 4 hours.；
3. It is fixed to clean the condenser every 3 months. For compressors that are air-cooled and cooled, the condenser fan should be overhauled regularly and the condenser should be decontaminated and dusted to ensure its good ventilation and heat transfer performance.For compressors that are water-cooled and cooled, in addition to ensuring their water inlet pressure and water inlet temperature, they must also ensure the corresponding flow rate, and regularly clean and descale the inside of the condenser to obtain its continuous heat transfer performance.；
4. Regular cleaning of the evaporator: Due to the different cleanliness levels of the test products, many small particulate matter such as dust will agglutinate on the evaporator under the effect of forced wind circulation, and it should be cleaned regularly.
5. There will be a lot of dust and other small particulate matter on the circulating blades and condenser fans, and they should be cleaned regularly.
