Important Notes:
Refrigerant Addition Required: 🛠️ The air conditioner does not come pre-charged with refrigerant; 600g of R134a 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.
