Troubleshooting

If you encounter any issues with your fan, refer to the following common problems and their solutions:

Fan Not Turning On:

• Check if the power plug is securely inserted into a working electrical outlet.
• Verify that all wiring connections to the fan and power plug are secure and correct.
• Ensure the power source voltage is within the fan's rated range (90V-240V AC).

Excessive Noise:

• Check for any obstructions in the fan's intake or exhaust ports.
• Ensure the fan is mounted securely and not vibrating against any surfaces.
• While the fan operates at 50dBA, which is audible, sudden increases in noise may indicate an issue.

Reduced Airflow:

• Inspect for dust or debris buildup on the fan blades or within the housing. Clean as per maintenance instructions.
• Ensure the intake and exhaust paths are clear and unobstructed.
