① The air conditioning lines and sockets must be dedicated for specific use only, as stated by the Beijing Chunlan Air Conditioning Repair Center. They should not be shared with other home appliances to prevent fires caused by overloaded wires or sockets. Therefore, during renovation, a separate wire should be pulled from the main power source for each room to set up a dedicated socket.
② The power supply used for air conditioners domestically is municipal electricity, i.e., single-phase 220V-50HZ. According to national standards, the usage range of air conditioners is 220V ±10% (i.e., 198V~242V). When the voltage exceeds this range, a voltage stabilizer should be installed to prevent the air conditioner from failing to start or run properly, which could even damage the air conditioner. The usage range of air conditioners (185V~242V) is higher than the national standard range, so it is recommended to purchase this type of wide-voltage air conditioner.
③ When purchasing wires, choose products from reputable manufacturers. The purity of copper in the wire core should be as high as possible, and aluminum-core wires should not be purchased.
④ Remember to set up an earth wire, as it is a guarantee for your life. Below are the specifications of the power cord that should be equipped with the air conditioner for reference:
It is recommended that: when pulling wires for each room, use 4mm² wires. First, this can avoid fires caused by poor-quality wires with low copper purity, and second, it can save electricity and prevent voltage drop losses caused by wires when the voltage is too low.
A few precautions for using wires with Chunlan air conditioners:
