This section provides general guidelines for installing the Maxxfan Dome Plus. Specific details may vary based on your vehicle or structure. Professional installation is recommended.
5.1 Pre-Installation Checks
- Ensure the mounting surface (rooftop or sidewall) is flat, clean, and structurally sound.

- Disconnect all 12V power to the installation area before proceeding.
5.2 Mounting Location
Select a location that allows for optimal airflow and is free from obstructions. Consider the fan's exhaust direction and potential rain entry points. The fan guard provides rain protection, but proper placement is still important.
5.3 Cutting the Opening
- Carefully measure and mark the exact dimensions for the fan opening. Refer to the template provided with your unit (if applicable) or the product dimensions.
- Use appropriate cutting tools to create the opening, ensuring clean edges.
- Seal all exposed edges of the cut opening with a suitable sealant to prevent moisture intrusion.
5.4 Wiring

- Connect the fan's positive and negative wires to the vehicle's 12V DC power supply, observing correct polarity.
- Secure all wire connections using crimp connectors or other approved methods.
5.5 Securing the Unit
- Apply a generous bead of approved sealant around the perimeter of the opening on the exterior surface.
- Carefully place the Maxxfan Dome Plus unit into the opening, pressing firmly to ensure a good seal.
- Secure the unit using the provided mounting hardware. Do not overtighten.
- Install the interior trim piece, if applicable, to cover the rough edges of the opening.
- Attach the fan guard to the exterior of the unit. This guard acts as a rain shield and protects the fan blades.
