1、 Overview

• 1. First, remove the dust filter according to the instructions. When disassembling, be careful not to touch the metal parts of the indoor unit to prevent scratching.
• 2. After removing the air filter, gently tap or use an electric vacuum cleaner. If the filter accumulates too much dust, rinse it with water or use a soft brush dipped in neutral detergent to clean it. However, the water temperature should not exceed 50 degrees Celsius during cleaning. Do not use laundry detergent, dishwashing liquid, gasoline, banana water, etc. to avoid deformation of the filter. Additionally, do not use sea surface cleaning as it may damage the surface of the dust filter.
• 3. After rinsing with clean water, dry with a soft cloth or blow dry in a cool place. Do not expose to direct sunlight or dry in open flames such as stoves to prevent deformation of the dust filter.
• When cleaning the panel, gently wipe it with a soft cloth dipped in warm water or neutral detergent, and then dry it with a dry soft cloth.

2、 Detailed Introduction

The accumulation of dirt on the surface area of pipes, filters, and heat exchange surfaces during the cleaning of central air conditioning can reduce the system's heat transfer efficiency, increase ventilation resistance, lower the quality of air conditioning operation, increase unnecessary energy consumption, and greatly increase the system's operating costs. With the improvement of living standards, more and more people are choosing home central air conditioning. For households with an area of over 200 square meters, using household central air conditioning is indeed more convenient and practical than installing many air conditioners. So how can we do a good job in maintaining household central air conditioning, so that the air conditioning can maintain good performance and normal lifespan? In the daily maintenance of household central air conditioning, we should pay attention to the following issues:

1. Regularly check whether the electrical plug and socket of the central air conditioner are in good contact. If it is found that the power supply is damaged or the plug is hot when the air conditioner is running, it may be due to thin electrical wiring or poor contact between the plug and socket. Corresponding solutions should be taken according to the situation.

2. Pay attention to whether there is water leakage in the pipeline connection of the water system. If it is a multi split system and an air duct system, it is necessary to regularly observe whether there is refrigerant leakage at the interface of the air conditioner refrigerant pipeline. If oil stains are found during the cleaning of central air conditioning, it indicates that there is refrigerant leakage, which should be dealt with in a timely manner to avoid insufficient refrigerant due to long-term leakage, which may affect the cooling (heating) effect of the air conditioner and even cause damage to the compressor.

3. The water system and air duct system should regularly clean the filter screens. Generally, it should be cleaned once every 2-3 weeks. When cleaning, remove the filter screen and use a dry soft bristled brush to brush away the dust on the filter screen. You can also wash away the dust on the filter screen with clean water. After drying, put it into the air conditioner for use. For environments with a lot of dust, the cleaning of the filter screen should be more frequent to avoid too much dust affecting the air conditioning unit's airflow.

4. Multi split household central air conditioners should regularly clean the condenser and evaporator coils of the air conditioner, and use brushes and vacuum cleaners to clean the dust on the coils. Pay attention to cleaning the brush and vacuum cleaner along the vertical direction of the coil, and do not clean horizontally to avoid damaging the ribs of the coil.

When the air conditioner needs to be shut down for a long time (such as seasonal shutdown), it should be thoroughly cleaned. After cleaning the central air conditioning, only turn on the fan of the air conditioner and run it for about 2-3 hours to dry the inside of the air conditioner. Then, cover the air conditioner with a dust cover.
