2. Installation Steps (Professional Installation Recommended)
- Prepare the Opening: If a new opening is required, carefully cut the roof opening to the specified dimensions. Ensure the edges are sealed to prevent water intrusion.
- Apply Sealant: Apply the provided sealant tape around the base of the outdoor AC unit where it will contact the roof.
- Position Outdoor Unit: Carefully lift and position the outdoor AC unit over the roof opening. Ensure it is centered and aligned.
- Install Indoor Air Distribution Box: From inside the vehicle, align the indoor air distribution box with the opening.
- Secure the Unit: Use the pull rods and mounting accessories kit to securely fasten the indoor and outdoor units together, sandwiching the roof. Tighten evenly to ensure a watertight seal.
- Connect Drain Pipes: Attach the drain pipes to the designated outlets on the unit and route them to allow for proper water drainage away from the vehicle.
- Electrical Connection: Connect the 12V DC power wires to the unit, ensuring correct polarity (+ to + and - to -). Use appropriate gauge wiring and circuit protection (fuse/breaker) as per electrical standards.
- Test Operation: Once all connections are secure, restore power and test the unit's functionality.
