1. The power supply voltage should not fluctuate too much (allowing ±10% fluctuation), and the air conditioner should be powered by a dedicated line, using a single-phase three-hole socket, and the plug should be inserted all the way. 2, the outer casing of the indoor unit should be cleaned frequently. Generally, it can be wiped clean with a clean dry cloth or wiped with a neutral detergent. It is absolutely not allowed to wash directly with water. If it is wiped with a cloth, it should be done after power off. 3, the indoor temperature can not be adjusted too low, otherwise it is unfavorable to the human body, the set temperature should be properly adjusted. 4. If you feel that the room temperature is too high, you can lower the set temperature appropriately. 5, the effective use of the timer, can achieve energy-saving and comfortable effects. 6, the air-conditioned room personnel should not be too much, too crowded, otherwise the cooling is insufficient, the temperature is difficult to drop; 7, room doors and windows can not be frequently switched, personnel can not enter and exit frequently, so as to avoid loss of air-conditioning; 8, the glass window must be tight and tight, the interior should be double-layered white curtains to reflect a part of the penetration of light and heat; 9, when the indoor ventilation can open the window for a short time, the window opening time is generally no more than 10 minutes; 10, the air filter should be cleaned regularly, otherwise the airflow is blocked, resulting in insufficient air volume, room temperature rise; 11, the temperature should be adjusted during sleep, the air conditioner can automatically adjust the sleep temperature; 12. The outdoor unit should be installed firmly to reduce vibration and noise. There should be enough space in front of the suction and exhaust ports of the condenser to facilitate ventilation. If the wind is blocked, the increase of the condensing pressure will cause the machine to stop. 13, there should be no obstacles in front of the indoor unit, otherwise it will affect the wind; 14. When the air conditioner is running, the selector switch can be adjusted to the high speed gear for rapid cooling, and then adjusted to the medium speed low speed gear after the temperature is lowered; 15, window air conditioner ventilation can use ventilation switch, but the ventilation time does not exceed 15 minutes; 16, too much dust on the outdoor radiator of the air conditioner will reduce the efficiency. The outdoor radiator should be inspected and cleaned regularly (after the power failure, it can be blown off with compressed air); 17, split-type air conditioner outdoor unit can not be inserted with sticks, otherwise the fan will be stuck or damaged; 18, when you feel that the air conditioner is not ideal, you should consult the instruction manual to analyze whether it is caused by improper use, and correct it after finding out the cause; 19. If you can't handle the fault after you find it, you can find the professional repair technician of the original installation department, or contact the local service personnel of the brand company. You can't repair it yourself or look for non-professional maintenance. 20, when the air conditioner is not in use, the power should be removed in time; 21, after the air conditioner is stopped, it must be restarted after three minutes to protect the compressor; 22, air conditioner with remote control (not should be placed in the child's easy access), do not be used as a toy in the use of the toy, so as not to damage the machine. The new type of air conditioner that can continuously adjust the frequency or speed of the compressor within a certain range, can change the flow rate of the refrigerant, and automatically adjust the output by the ability to match the environment. Inverter air conditioners combine digital signal processing and analog control with artificial intelligence control. Compared with ordinary air conditioners, inverter air conditioners have the advantages of rapid cooling and heating, high efficiency, energy saving, comfortable and reliable, intelligent defrosting, large dehumidification, ultra-quiet, wide voltage operation and so on.
