What is the cleaning method of home air conditioner host?

A, cleaning the air conditioning unit should be carried out after cleaning the return air duct, and close the air valve on the air supply and return air duct. If it is an electric valve, please ask the property department to help close it. B, take out the air filter on the return air section, clean it with water in the water room and put it in a well-ventilated place to dry. C, use the suction vacuum cleaner to clean the dust on the four walls and the box of the heat exchange coil in the return air section of the unit, and use compressed air to blow clean the dust in the inner gap of the heat exchange coil. During operation, the fins of the coil should be prevented from bending and deformation, and dust should be collected with a vacuum cleaner while blowing. D, after the dust collection, wash the wall and heat exchange coil with water, and drain the sewage into the floor drain of the computer room through the drain pipe. After cleaning, blow dry with compressed air. E, in the air supply section of the unit, it is strictly prohibited to wash directly with water because of the motor and junction box. First, wrap the fan and wire box tightly with a cover to prevent water from entering. Use a vacuum cleaner to clean the dust on the four walls of the heat exchange coil and the air supply section box, and use compressed air to spray the dust in the gap in the inner layer of the heat exchange coil. During operation, the fins of the coil should be prevented from bending and deformation, and dust should be collected with a vacuum cleaner during spraying. F, remove the plastic bag wrapped around the fan and junction box, and check whether the fan and junction box are flooded, otherwise it should be handled in time.
