"Some families think that they can use the air conditioner once and for all. They don't know how to maintain it, which affects the service life and the air quality of the home. In fact, air conditioning needs care and maintenance just like people. Proper maintenance of air conditioner can not only improve the efficiency and service life of air conditioner, but also reduce the failure rate and air pollution chance of air conditioner. The general maintenance methods are as follows: 1. Often clean the air filter screen: generally, clean it once every 2-3 weeks. The steps are: remove the panel - draw out the air filter - clean the air filter screen. Put the air filter screen in the tap water for washing. Since the filter screen is made of plastic frame fiber, it cannot be cleaned with hot water above 40 ℃ to prevent shrinkage and deformation. After cleaning, the water on the filter screen can be dried and inserted into the panel to install the air conditioner. 2. Protection of condenser and evaporator: the heat sink is made of 0.15 m aluminum sheet covered with copper tube and then expanded. It can not withstand collision. If the heat sink is damaged (inverted), the cooling effect of air conditioner will be affected and the refrigeration efficiency will be reduced. Therefore, special attention should be paid to the protection. 3. Protect the refrigeration system: if the components or connecting pipes of the refrigeration system are damaged, the refrigerant will leak out, and the air conditioner will not be able to cool or heat. 4. Correct selection of fusing (fuse): select the specification of fuse according to the rated current in the product manual. If it is too large, it will not work as a fuse, and if it is too small, it will be easy to fuse. 5. The operation time of remote control stop and start of air conditioner shall be more than 3 minutes, and continuous stop and start are not allowed. 6. Protect the electrical system from moisture. Electrical system is easy to leak electricity after being damped. So the electrical system parts must avoid water, especially in the rainy season, more attention should be paid to moisture. 7. Always check whether the power plug and socket are in good contact and whether they are loose or fall off. 8. Pay attention to the operation sound of the air conditioner. When you hear the abnormal noise of the air conditioner when it is running, such as metal collision sound, motor buzzing sound, shell vibration sound, etc., you should immediately shut down the machine to check the cause, and must not blindly continue to use, to avoid greater damage. 9. Wipe the exterior surface of the air conditioner, especially the panel part, to keep the air conditioner clean. Remove dust from outdoor cooler with long brush every six months. 10. When the air conditioner is not used for a long time, the battery of the remote controller should be taken to cut off the power supply of the air conditioner."
