Product installation and instructions

Choose a stable and flat installation surface for the SF series low-noise axial flow fan. Ensure the area is free from obstructions that could impede airflow or cause vibrations during
If wall-mounting, mark the drill holes accurately according to the fan’s mounting template. Use appropriate anchors and screws for the wall material to guarantee a secure attachment.
Carefully lift the fan into place, aligning it with the mounting points. Double-check the orientation to ensure the airflow direction matches your requirements.
Have a qualified electrician connect the fan to the power supply following local electrical codes. Make sure the wiring is properly insulated to prevent electrical hazards.
Apply a suitable sealant around the fan’s mounting edges to prevent air leakage and enhance the overall efficiency of the ventilation system.

Note: Before turning on the fan for the first time, inspect it for any signs of damage or loose parts. Then, switch it on briefly to check for abnormal noises or vibrations.

Operate the fan as needed to maintain proper ventilation. Avoid running it continuously at maximum speed unless necessary to extend its lifespan and reduce energy consumption.
Periodically clean the fan blades and housing to remove dust and debris that could affect performance and increase noise levels. Also, inspect the electrical connections for any signs of wear or corrosion.
