4. Setup and Installation
Follow these steps to install your Dioche Car Window Portable Solar Powered Ventilator:
- Prepare the Window: Clean the upper edge of your car window frame where the ventilator will be mounted. Ensure the surface is dry and free of dust or grease.
- Attach Adhesive Tape: The ventilator comes with a length of adhesive tape. Carefully apply this tape along the top edge of the ventilator's mounting surface. Ensure a firm and even application.
- Position the Ventilator: Place the ventilator on the upper edge of your car window. The solar panel should face outwards to receive direct sunlight. The fans should face inwards towards the car's interior.
- Secure the Ventilator: Press the ventilator firmly against the window frame to ensure the adhesive tape creates a strong bond. For optimal adhesion, allow the adhesive to set for a few hours before operating the device.
- Battery Installation (if not pre-installed): If the AA batteries are not already installed, open the battery compartment (usually located on the underside or side of the unit) and insert the two AA 1200mAh batteries, observing the correct polarity (+/-).

5. Operating Instructions
The ventilator is designed for straightforward operation:
- Power On/Off: Locate the 'ON/OFF' switches on the front panel of the ventilator. Each fan may have an individual switch or a master switch for all fans. Toggle the switch(es) to the 'ON' position to activate the fans.
- Solar Power Operation: When exposed to direct sunlight, the solar panel will power the fans and recharge the internal batteries. For optimal performance, ensure the solar panel is unobstructed.
- Battery Power Operation: In low light conditions or when solar power is insufficient, the ventilator will draw power from the installed AA batteries. The batteries provide approximately 3 hours of continuous operation.
- Air Circulation: The three fans will begin to rotate at 5000 RPM, drawing hot air and odors out of the car and promoting fresh air intake.
- Odor Removal: Continuous operation helps to quickly expel unpleasant odors from the vehicle's interior, such as those from pets or cigarettes.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your ventilator:
- Cleaning the Solar Panel: Periodically wipe the solar panel with a soft, damp cloth to remove dust, dirt, or debris that may obstruct sunlight and reduce charging efficiency. Do not use abrasive cleaners.
- Cleaning Fan Blades: If dust accumulates on the fan blades, gently clean them with a soft brush or compressed air. Ensure the device is turned off before cleaning.
- Battery Replacement: If the ventilator's performance on battery power diminishes significantly, replace the two AA batteries with new ones of the same specification (1200mAh). Dispose of old batteries responsibly.
- Storage: If storing the ventilator for an extended period, remove the batteries to prevent leakage and store the unit in a cool, dry place away from direct sunlight.

7. Troubleshooting
If you encounter issues with your ventilator, refer to the following common solutions:
- Fans Not Operating:
- Ensure the 'ON/OFF' switches are in the 'ON' position.
- Check if the solar panel is receiving direct sunlight.
- Verify that the AA batteries are correctly installed and not depleted. Replace if necessary.
- Low Airflow:
- Clean any dust or debris from the fan blades and grilles.
- Ensure the solar panel is clean and exposed to sufficient sunlight.
- Check battery charge if operating without direct sunlight.
- Ventilator Detaches from Window:
- Re-apply the adhesive tape, ensuring the window surface is clean and dry before application.
- Press firmly during installation and allow sufficient time for the adhesive to bond.
8. Safety Information
