The installation process for a wall fan will vary depending on the specific model and manufacturer. In general, however, you will need to locate a suitable mounting location on the wall and then secure the fan bracket to the wall using screws. Next, you will need to attach the motor assembly to the bracket and wire the fan to an electrical circuit. Finally, you will need to install the fan blades and any other accessories, such as a remote control. It is recommended that you follow the manufacturer's instructions carefully and, if necessary, seek the assistance of a professional electrician.
