Important Notes:

Refrigerant Addition Required: 🛠️ The air conditioner does not come pre-charged with refrigerant; 600g of R1234yf/R134a(No Included) needs to be added before use.

Pre-Added Refrigeration Oil: 🛢️ The unit already contains POE68 refrigeration oil; no additional oil is necessary.

Vacuum Process: 🧰 It's essential to vacuum the system for 15-20 minutes before adding refrigerant to ensure optimal performance.

Refrigerant Pressure Specifications: 📏 When adding refrigerant, aim for a low-pressure gauge reading of 35 psi and a high-pressure reading between 140-180 psi.

 

Battery and Generator Requirements:

For 12V systems: Minimum 100A battery and a 1500W generator.

For 24V systems: Minimum 80Ah battery and a 55A generator.

Ensure your vehicle's battery meets these requirements for optimal operation.

Common Q&A:

❓ How should I maintain the air conditioner?
✔️ Turn off the power before cleaning. Use a neutral cleaning agent for surface cleaning. Remove the outer shell and blow out dust with high-pressure air. Regularly check the battery power and ensure air vents are clear.

❓ What should I do if the battery power is low?
✔️ If the system enters low-voltage protection, switch to energy-saving mode for temporary operation. However, it's recommended to recharge the battery as soon as possible.

❓ How do I troubleshoot abnormal operation?
✔️ Check the error code on the display panel or compressor LED light. Refer to the user manual for troubleshooting instructions.
