8. Maintenance

Regular maintenance helps ensure optimal performance and longevity of your air conditioner unit.

• Filter Cleaning: Periodically check and clean the pre-filter to maintain efficient airflow. Refer to your vehicle's manual for accessing the filter if applicable.

• Exterior Cleaning: Wipe the exterior of the unit with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.

9. Troubleshooting

If you encounter issues with your air conditioner, refer to the following common troubleshooting steps. For complex problems, consult a professional technician.

• No Airflow: Check if the fan speed knob is set to '0'. Ensure the vehicle's electrical system is providing power to the unit. Check for any obstructions in the air vents.
• Weak Airflow: Clean or replace the pre-filter if it is clogged. Ensure the fan speed is set to a higher setting.
• No Cooling: Verify that the temperature knob is set to 'ON' or a colder setting. Ensure the external compressor and condenser are functioning correctly and the refrigerant level is adequate. This unit requires a fully charged AC system to provide cooling.
