7. Maintenance
Regular maintenance ensures optimal performance and longevity of your booster fan.
- Cleaning: Ensure the device is unplugged from the power outlet before cleaning. Wipe the exterior surfaces with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the unit in water.
- Obstruction Check: Periodically check the fan intake and exhaust for any dust buildup or obstructions that could impede airflow.
8. Troubleshooting
Refer to this section for solutions to common issues.
- Fan cycles on/off frequently: If the set temperature is very close to the ambient temperature, the fan may cycle frequently. For more stable operation, increase the temperature difference between your set trigger temperature and the current ambient temperature.
- Device beeps and stops working: Unplug the unit from the wall outlet, wait for approximately 30 seconds, then plug it back in. If the issue persists, contact customer support.
- No airflow or weak airflow: Check that the power cord is securely plugged in. Ensure there are no obstructions blocking the fan's intake or exhaust vents.
- Remote control not responding: Check the battery in the remote control and replace if necessary. Ensure there is a clear line of sight between the remote and the fan's sensor.
