First of all, when connecting the centrifugal cooling fan, the foundation joint surface, and the inlet and outlet air ducts, they should be adjusted to fit naturally, not forcibly connected, and the weight of the air ducts should not be concentrated on the casing to avoid deformation of the casing and affect the normal operation. The inlet and outlet air ducts of the centrifugal fan should be connected with hoses, and attention should be paid to the horizontal position of the fan.

Secondly, when installing the centrifugal ventilation fan, it is necessary to first check whether the connection of each part is tight, whether the rotation is sensitive, etc., and also check whether there are debris in the casing. After the installation is completed, it is necessary to check whether the installation tools are left out. Otherwise, it will affect the normal use of the fan, and even threaten the performance of the fan.

Finally, after the installation is completed, the trial operation can be carried out only after all parts are confirmed to be normal. In the process of trial operation, the current should be well controlled and the rated value should not be exceeded. In order to prevent the motor from being burnt due to overload, it must be carried out under no load when the 12 volt centrifugal fan is started and tested. If the condition is good, gradually open the valve until the specified operating conditions. After installation, try to rotate the impeller to check whether it is sensitive. If it is found to be wrong, it should be adjusted in time.
