4. Setup and Installation

This section outlines the general steps for installing the Maxxfan Mini Plus Vent. Professional installation is recommended if you are unfamiliar with RV electrical systems or roof modifications.

4.1 Pre-Installation

1. Choose Location: Select a suitable location on your RV roof, typically replacing an existing vent or in a new 14" x 14" opening.
2. Disconnect Power: Turn off all 12V DC power to your RV to prevent electrical shock.
3. Gather Tools: You will need a drill, screwdriver, sealant gun, butyl tape, self-leveling caulk, and potentially a cutting tool for the roof opening.
4. Remove Old Vent (if applicable): Carefully remove any existing vent, ensuring all old sealant and adhesive residue is thoroughly cleaned from the roof surface. This step can be challenging due to strong adhesives used by manufacturers.

4.2 Installation Steps

1. Prepare Opening: Ensure the roof opening is clean, dry, and measures 14" x 14".
2. Apply Butyl Tape: Apply a continuous bead of butyl tape around the perimeter of the vent flange that will sit on the roof.
3. Position Vent: Carefully place the vent assembly into the roof opening. The vent opening should ideally face towards the rear of the vehicle to minimize wind resistance and water intrusion during travel.

5. Secure Vent: From inside the RV, attach the interior trim ring and secure the vent to the roof using the provided screws. Ensure a tight, even seal. It is helpful to have a second person assist with aligning the components and securing them.
6. Cut Sleeve: The sleeve that fits between the roof vent and ceiling cover may need to be cut to match your RV's roof thickness.
7. Wiring: Connect the fan's 12V DC wires to your RV's electrical system. Typically, red is positive (+) and black is negative (-). Ensure connections are secure and insulated. The fan draws less than 2 amps.

9. Apply Sealant: Apply a generous bead of RV-grade self-leveling caulk over all screw heads and along the edge of the vent flange on the roof to create a watertight seal.

Important Note: Some users have reported improved efficiency by sealing the borders of the interior part of the fan with additional sealant to prevent air leakage. This can be done after the main installation.

5. Operating Instructions

The Maxxfan Mini Plus Vent is designed for simple operation.

1. Power On/Off: Locate the power switch, typically a push-button, on the interior trim of the fan. Press to turn the fan and LED lights on or off.
2. Vent Opening/Closing: The vent features a lever mechanism to open and close the baffle around the fan. This allows you to control airflow and protect the interior from elements.
   • To open: Move the lever to align the internal and external openings, allowing air to flow.
   • To close: Move the lever to misalign the openings, sealing the vent.
3. LED Lighting: The integrated "Cool" L.E.D. lighting provides ambient light and can be used independently or with the fan.

6. Maintenance

Regular maintenance ensures optimal performance and longevity of your Maxxfan Mini Plus Vent.

• Cleaning: Periodically clean the fan blades and interior grille with a soft, damp cloth. Ensure the fan is turned off and power is disconnected before cleaning.
• Exterior Cleaning: Clean the exterior vent cover with mild soap and water. Avoid abrasive cleaners that could damage the plastic.
• Seal Inspection: Regularly inspect the sealant around the vent on the RV roof for cracks or deterioration. Reapply sealant as necessary to prevent leaks. Pay close attention to the seal between the two "bowls" of the vent mechanism, as this can be a point of air leakage.
• Functionality Check: Periodically check the fan and LED lights for proper operation. Ensure the opening/closing lever moves freely.
