4. Operating Instructions
The iPower exhaust fan features a 3-speed controller for adjustable airflow.
- Power On/Off: Turn the knob on the speed controller to the 'OFF' position to power off the fan. Rotate the knob clockwise to turn the fan on and select a speed setting.
- Adjusting Speed: The speed controller allows adjustment from 50% to 100% of the fan's maximum speed. Settings include LOW, MED (Medium), and HIGH.
- Important Note: To prevent damage to the fan motor, the controller does not adjust below 50% speed. Operating the fan below this range may risk burning out the motor.
- Automatic Shutters: When the fan is running, the automatic shutters will open to allow airflow. When the fan is turned off, the shutters will close automatically due to gravity, providing protection against insects and dust.
