How to add R410A refrigerant?

　　【】The pressure of R410A is about 1.6 times higher than that of R22 refrigerant. Therefore, once the wrong operation occurs during the construction and after-sales service process, a major accident may occur. When installing r410a refrigerant air conditioners, use R410A special tools and materials, and pay attention to safe operation.

　　(1) Before operation, confirm the name of the air conditioner refrigerant, and then perform different operations on different refrigerants. In household air conditioners that use R410A refrigerant, you must never use refrigerants other than R410A. R410A refrigerant must not be used in air conditioners.

　　(2) If refrigerant leaks during operation, please ventilate in time.

　　 (3) When installing or moving the air conditioner, please do not mix air other than R410A refrigerant into the air conditioner's refrigerant circulation pipeline. If non-condensable gas such as air is mixed in, it will cause abnormal high pressure in the refrigerant circulation pipeline, which is the main cause of rupture and cracks in the circulation pipeline.

　　(4) After the installation work is over, please confirm carefully that there is no leakage of refrigerant. If the refrigerant leaks indoors, once it comes into contact with electric sparks from electric fans, heaters, electric stoves, etc., it will form toxic gas.

　　(5) When installing one-to-multiple air conditioners, because the amount of enclosed refrigerant is relatively large, especially in small rooms, even if the refrigerant leaks, its concentration cannot exceed the specified value. Otherwise, it will cause hypoxia.

　　(6) When installing and moving the air conditioner, please implement it reliably in accordance with the requirements of the manual. In the event of improper installation, it will cause abnormal operation of the refrigerant circulation pipeline, water leakage, electric shock, fire and other phenomena.

　　(7) Please never modify the air conditioner privately, and ask professionals to perform repairs. Improper repairs can also cause water leakage, electric shock, and fire.
