5. Installation Instructions
Professional installation is recommended for optimal performance and safety.
5.1. Pre-Installation Checklist
- Verify all components listed in Section 3.4 are present and undamaged.
- Ensure the vehicle's electrical system can support a 12V DC, 800W (960W peak) load.
- Select appropriate mounting locations for both indoor and outdoor units, ensuring proper air circulation and drainage.
- Gather necessary tools: drill, wrenches, screwdrivers, vacuum pump, refrigerant gauges, safety glasses, gloves.
5.2. Step-by-Step Installation
Image 5.1: Installation Steps Overview
This diagram illustrates the eight primary steps involved in installing the Treeligo 12V DC Mini Split Air Conditioner, from mounting units to connecting power and refrigerant.
- Install External Machine: Securely mount the outdoor unit in the chosen location on the vehicle. Ensure it is level and has adequate clearance for airflow.
- Install Expansion Valve: Connect the expansion valve to the appropriate lines as per the diagram.
- Install Indoor Unit: Mount the indoor unit inside the vehicle cabin. Ensure it is securely fastened and positioned for optimal air distribution.
- Install High & Low Pressure Pipelines: Connect the high and low pressure refrigerant lines between the indoor and outdoor units. Ensure all connections are tight and leak-free.
- Install Connecting Line, Drain Pipe, and Power Line: Connect the signal cable, drain pipe, and main power cable. The drain pipe should be routed to allow condensate to exit the vehicle without causing damage.
- Vacuum and Add Refrigerant: Evacuate the system using a vacuum pump to remove air and moisture. Then, charge the system with the specified amount of R-134A refrigerant. This step requires specialized tools and expertise.
- Connect the Power Cord to the Battery: Connect the main power cable directly to the vehicle's 12V DC battery, ensuring correct polarity and a secure connection. Install an inline fuse if not already present.
- Turn on the Air Conditioner: Once all connections are secure and the system is charged, power on the unit and test its operation.
