How to Install a Split-Type Parking Air Conditioner

For long-haul transport and heavy-duty logistics drivers, a high-performance, quiet split-type parking air conditioner not only improves rest quality but also ensures a comfortable cabin environment in extreme heat or cold. However, to achieve optimal performance, proper installation is essential. This guide breaks down the installation process step by step to help you complete it with ease and ensure stable and efficient system operation.

What Is a Split-Type Parking Air Conditioner?

A split parking air conditioner typically consists of two main components:

Indoor unit: Installed inside the cabin and responsible for blowing cool air.

Outdoor unit: Installed outside the vehicle (e.g., rear wall or rooftop) and houses the compressor, condenser, and other key components.

Compared to integrated rooftop units, split models offer greater flexibility in installation and do not require a roof opening, making them ideal for most trucks without sunroofs.

Preparation Before Installation

1. Determine Installation Position

Outdoor unit: Can be rear-mounted (eg., CB26/CB26H) or roof-mounted (eg., CT26), depending on your truck's design.

Indoor unit: Ideally mounted behind or above the driver’s seat to ensure smooth airflow and no obstruction to visibility.

2. Tools and Materials Required

Electric drill, screwdriver, wrench,Bolts and nuts, sealing gaskets, zip ties,Refrigerant pipes, power cables, drain hose,Rubber pads or foam tape (for vibration and noise reduction)

Step-by-Step Installation Process

Step 1: Mount the Outdoor Unit

• Use the provided bracket template to drill holes on the truck's outer body.
• Secure the outdoor unit to the bracket with bolts and sealing pads to ensure it is shock-resistant and stable.
• Add rubber pads to minimize vibration and noise during operation.

Step 2: Install the Indoor Unit

• Select an appropriate spot inside the cabin.
• Fix the indoor unit securely with screws.
• Ensure there is enough clearance for smooth airflow.

Step 3: Connect Piping and Wiring

• Connect the refrigerant copper pipes between the indoor and outdoor units using the manufacturer's accessories. Ensure there are no leaks.
• Connect the power cable—ideally to the auxiliary battery—with fuse protection.
• Extend the drain hose outward to prevent water accumulation inside the cabin.

Step 4: Vacuuming and Refrigerant Charging (if applicable)

• Use a vacuum pump to remove air and moisture from the piping.
• Some models require refrigerant (e.g., R134a or R410A). Charge according to the product label.

Step 5: Power On and Test

• Turn on the air conditioner and check airflow, cooling, and fan speed adjustment.
• Inspect for unusual noises, water leakage, or weak cooling performance.
• Ensure all connections are secure and the control panel responds normally.

Installation Tips

• Ensure correct voltage (eg., 12V or 24V) to avoid damaging the equipment.
• Installation by a qualified technician is strongly recommended to prevent errors.
• After installation, perform a system check and cleaning every six months to extend service life.
