The following are the maintenance methods for the cold and hot shock test chamber:

Before operating the machine, the internal debris should be removed first.

2. The bottom of the fuselage and the surrounding ground should be kept clean for a long time to avoid accidents and performance degradation caused by a large amount of dust being sucked into the unit

3. When taking the test object from the furnace and opening and closing the door, prevent the object from coming into contact with the adhesive edge on the door, so as not to damage the adhesive edge and shorten its lifespan

4. Inspection and maintenance of waterways. The water pipes in waterways are components that are prone to blockage and leakage. It is recommended to regularly check for water leakage and blockage. If any problems occur, please promptly troubleshoot or notify our company.

5. The high current contacts of the distribution panel should be cleaned and maintained at least once a year in the distribution room. Loose contacts may cause the entire equipment to be in a dangerous working state, ranging from burning components to fire, alarm, and personal injury. When cleaning, use a vacuum cleaner to remove indoor dust and wipe with soap and water.

6. Please do not adjust the set values of the two over temperature protectors in the distribution box casually. They have been adjusted before leaving the factory. This protection switch is used to protect the heating and humidification pipes from air burning and water shortage alarms. The set point of the cold and hot shock test box is the temperature set point of 20 ℃ to 30 ℃

7. The radiator (condenser) of the refrigeration unit should be regularly maintained and kept clean. Dust sticking to the condenser can cause the high-pressure switch of the compressor to trip and generate false alarms. The condenser of the cold and hot shock test box should be regularly maintained monthly. Use a vacuum cleaner to remove the dust attached to the condenser's heat dissipation mesh, or use a hard brush or high-pressure nozzle to blow away the dust after starting up.

8. When the test product time is up and the product is taken, it must be in the off state and the staff must wear dry, anti electric, and temperature resistant gloves to take and place the product

9. The refrigeration system of the cold and hot impact testing machine is the core of the testing machine. Every year, all copper pipes must be inspected for any leakage or snow, as well as all horn joints and welding joints. If there is any oil leakage, it is necessary to inspect them
