2. Safety Information
Please read and understand all safety instructions before installing or operating the Maxxfan Plus. Failure to follow these instructions may result in property damage, personal injury, or death.
- Electrical Safety: Disconnect all power to the RV's 12-volt system before beginning installation or maintenance. Ensure proper wiring and fuse protection (a 7-amp fuse is recommended if not already present).
- Installation Safety: Always wear appropriate personal protective equipment (PPE) during installation, including eye protection and gloves. Exercise caution when working on the RV roof.
- Ventilation: Ensure adequate ventilation when using sealants or adhesives during installation.
- Children and Pets: Keep children and pets away from the fan during operation and maintenance.
3. Installation
The Maxxfan Plus is designed to fit standard 14" x 14" RV roof openings. While mounting screws and hardware are included, roof sealant (such as butyl tape and self-leveling Dicor caulk) must be purchased separately.
For detailed, step-by-step installation instructions, please refer to the official user manual PDF available from the manufacturer or retailer. Professional installation is recommended if you are unfamiliar with RV electrical systems or roof modifications.
Key Installation Considerations:
- Ensure the roof opening is clean, dry, and free of old sealant residue.
- Properly seal all edges and screw holes to prevent water leaks.
- Connect the fan to a dedicated 12-volt power source with appropriate circuit protection.
- The exterior flange features waterproof, molded mounting holes for easy installation of a FANMATE Vent Cover (sold separately), which does not require tools.

4. Operating Instructions
The Maxxfan Plus offers intuitive controls for managing your RV's ventilation.
4.1. Ceiling Keypad Controls
The flush-mount ceiling keypad allows you to control various fan functions:
- Power On/Off: Activates or deactivates the fan.
- Fan Speed: Adjusts the fan speed through 10 settings.
- Intake/Exhaust: Toggles the fan direction to pull fresh air in or exhaust stale air out.
- Thermostat: Sets a desired temperature, allowing the fan to automatically turn on or off to maintain comfort.
4.2. Manual Lid Opening
The lid is opened and closed manually using a knob or crank mechanism located on the fan's interior trim. Ensure the lid is securely closed when the RV is in motion or during heavy rain.
4.3. Rain Sensor
The integrated rain sensor automatically detects moisture and closes the fan lid to protect your RV interior from rain. Once the sensor dries, the lid will remain closed until manually opened or the fan is operated in ceiling fan mode.
4.4. Ceiling Fan Mode
The fan can operate with the lid closed, circulating air inside your RV similar to a ceiling fan. This feature is useful for general air movement without opening the roof vent.

The interior insect screen is designed for easy removal and cleaning. Periodically remove the screen and wash it with mild soap and water. Ensure it is completely dry before re-installing.
5.2. General Cleaning
Clean the fan blades and housing with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the plastic components. Ensure the fan is turned off and power is disconnected before cleaning.

Inspect the lid opening mechanism periodically for smooth operation. Lubricate moving parts with a silicone-based lubricant if necessary.
