Setup and Installation
Follow these steps for proper installation of the air conditioning unit. Professional installation is recommended.
- Install the External Machine:
Remove the casing of the external unit. Mark the drilling positions on the vehicle. Use an 8mm drill bit to create the holes. Use a riveting tool to secure the rivet nuts at the drilling points. Install shock pads and sleeves at the holes of the external machine. Securely fix the external machine to the vehicle.

- Install the Expansion Valve:
Locate the position for the expansion valve on the evaporator. Remove any protective iron sheet. Fix the expansion valve to the evaporator. Ensure the two black screws align with the two corresponding holes for correct installation. Wrap the installed expansion valve with black cotton wrap.

- Install the Indoor Unit:
First, install a wooden board or suitable mounting surface to the interior wall of the vehicle. Then, mount the evaporator (indoor unit) onto this board.

- Install High & Low Pressure Pipelines:
Create a 50mm hole in the vehicle body for the pipes. Install the rubber cover with three holes into this opening. The thick pipe is the low-pressure line and connects to the compressor. The thin pipe is the high-pressure line and connects to the condenser. Connect the other ends of the high and low-pressure pipes to the corresponding holes on the expansion valve of the indoor unit. Use long black screws and iron sheets to clamp the aluminum joints and tighten the screws securely.

- Install the Connection Line, Drain Pipe, and Power Line:
Connect the electrical connection lines between the internal and external units. Plug the power cord plugs into each other. Connect the drain pipe from the evaporator to allow for condensate drainage.

- Vacuuming and Adding Refrigerant:
The system must be vacuumed for 15-20 minutes to remove air and moisture. After vacuuming, add R134a refrigerant, approximately 600g. The refrigerant amount can be adjusted based on pressure readings. Typically, after R134a injection, the low-pressure port should read 35psi, and the high-pressure port 140-180psi.

- Connect the Power Cord to the Battery:
Connect the power cord directly to the vehicle's battery. Pay close attention to the positive (+) and negative (-) terminals to avoid reverse connection. Do not connect to any power-off switches or general power switches.

Troubleshooting
If you encounter issues with your air conditioner, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not turn on | No power, loose connection, battery issue | Check battery connections, ensure sufficient battery charge. Verify all power cables are securely connected. |
| Insufficient cooling | Low refrigerant, dirty filters/coils, blocked airflow | Check refrigerant levels (professional service recommended). Clean air filters and coils. Ensure no obstructions to airflow. |
| Control panel displays an error code | Insufficient current, incorrect refrigerant level (too much or too little) | Check battery voltage and current supply. Verify refrigerant charge (professional service required). Consult the service center if the issue persists. |
| Unusual noise during operation | Loose components, fan obstruction | Inspect for any loose parts or debris obstructing the fan. If noise persists, contact support. |
