a) Dirty and clogged filter screen: In order to better ensure the working effect of the air conditioner, it is recommended to clean the filter screen every two weeks; b) Temperature setting (frequent startup and shutdown): If the set temperature is not appropriate (too high or too low) and the startup and shutdown are frequent, the effectiveness of the air conditioning will deteriorate. The reason is that the temperature difference between the top and bottom of the room is caused by air convection, which is a normal phenomenon. At this time, just refer to the manual to reset the temperature; c) Improper selection of the position of the air deflector: When the machine is working, the computer board has already selected the optimal direction of the air deflector based on the working mode, using air convection to achieve the overall best effect. It is recommended to refer to the manual and choose different directions of the air deflector according to different modes, or operate it through the computer board's customized program; d) Improper selection of indoor unit wind speed: If the wind speed is too small, it will cause the outlet temperature to be too low during refrigeration, causing the outlet to freeze under high temperature conditions, and the air flow rate is small, which cannot effectively bring out the cold air volume in the indoor unit; When heating, the wind speed is low, but the outlet temperature is high. The wind speed can be set according to different situations
