What is the fault of the air conditioner duct unit DL

1. Fault content: The compressor exhaust temperature is too high.

2. Cause of failure: The high exhaust temperature of the compressor is caused by too little refrigerant and lack of fluorine. When the amount of refrigerant is too little, the high pressure of the compressor will cause the refrigerant temperature to overheat, resulting in too high exhaust temperature. This phenomenon is often accompanied by frost or ice formation on the expansion valve. The reason is basically the same. Due to the small amount of refrigerant, the temperature and pressure drop below the minimum limit when the refrigerant is lowered, causing the refrigerant to be overcooled, so it is easy to freeze.

3. Troubleshooting: Adding an appropriate amount of fluorine can solve the problem.

How to exit the memory mode of the air conditioner duct unit

1. Cut off the power and restart to exit.

2. Restore to factory settings to exit.

A duct air conditioner is a duct air conditioner. The air conditioner is connected to the air duct to supply air to the room. The so-called high static pressure duct air conditioner is a duct air conditioner that uses a high static pressure fan. The static pressure of the air conditioner is equivalent to the residual pressure outside the machine. This is a parameter of the air supply capacity of the air conditioner. The greater the static pressure, the longer the air supply head. Because the air supply of the duct air conditioner needs to pass through the air duct, the air pressure loss will increase during the air supply process. If a high static pressure fan is not used, the wind delivered to the room will be very small.

How to decode the duct machine when it is turned on for the first time

When the air conditioner leaves the factory, the manufacturer places barcodes on the indoor unit, outdoor unit, and compressor. There are two more barcodes in the packaging bag of the warranty card, one for the indoor unit and one for the outdoor unit, and they are the same as the barcode on the body. The barcode in the packaging bag is for the dealer. As the installation certificate of the air conditioner, the installation card is affixed with the barcodes of the indoor and outdoor units, the customer's name, and the installation location.

Unlocking method for first time startup:

1. The first time the air conditioner is turned on, a password is required. The password must be obtained from the relevant software by the staff of the authorized service outlets. It can only be used after being unlocked with a special unlocking remote control. After successful unlocking, the password will no longer be required.

2. If you are not a professional, you need to contact the dealer where you purchased the product and arrange for relevant staff to come to your home to unlock the duct machine.
