Hidden danger one: leakage of fluorine
Detection method: Before the test machine, the refrigerant leakage inspection should be carried out first. The leakage detection is mainly for the four interfaces of the air conditioner inside and outside the machine and the valve port of the shut-off valve.
Hidden danger 2: leakage
Detection method: Let the installer carry the relevant power detection tool to perform safety detection on the power supply.
Hidden danger three: leakage of indoor unit connecting pipe
Detection method: After the central air conditioner is installed, the central air conditioner will be installed immediately. If there is no water droplet for a period of time, there will be no problem. You can also ask the installer to conduct a leak test for you to protect your own interests.
Hidden danger four: installation location
Central air-conditioning indoor unit installation generally requires that the air outlet has no obstructions, and it is best to install it before indoor decoration. The installation of the outdoor unit should avoid direct sunlight, poor heat dissipation, etc., avoiding hidden dangers such as flammable gases and highly corrosive gases. The installation location should be easy to install and repair, to avoid late failure and poor maintenance.
Hidden danger five: noise
The noise is the most unacceptable, and it is easy for the installer to find the problem and correct the problem in time.
