Installation

The Fan-Tastic Vent 801250 is designed to fit standard 14" x 14" roof openings. Installation typically involves the following general steps:

1. Preparation: Carefully remove any existing vent or prepare a new 14" x 14" opening in the RV roof. Ensure the area is clean, dry, and free of debris.
2. Mounting: Position the vent assembly into the opening. Secure the vent to the roof using appropriate fasteners.
3. Sealing: Apply a high-quality, UV-resistant roof sealant around the perimeter of the vent flange to create a watertight seal. Ensure all screw heads are also sealed.
4. Wiring: Connect the vent's 12V DC wiring to a suitable 12V DC power source within the RV. Observe correct polarity (positive to positive, negative to negative).
5. Interior Trim: Install the interior trim piece, ensuring it fits snugly against the ceiling.

Professional installation is recommended if you are unfamiliar with RV electrical systems or roof modifications to ensure safety and proper sealing.

• Off (0): The fan is not operating.
• Low (1): Provides gentle air circulation.
• Medium (2): Offers moderate airflow.
• High (3): Delivers maximum airflow for rapid ventilation.

Rotate the rotary dial to select your desired fan speed.

Airflow Direction

The vent features a reversible airflow switch, allowing you to either exhaust air out of the RV or draw fresh air in.

Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your Fan-Tastic Vent.

• Cleaning Fan Blades and Screen: Periodically clean the fan blades and the interior mesh screen to remove accumulated dust, dirt, and debris. Ensure the fan is off and power is disconnected before cleaning. Use a soft cloth and a mild, non-abrasive detergent.
• Dome and Seal Inspection: Annually inspect the vent dome and its rubber seal for any signs of wear, cracking, or damage. Check the roof sealant around the vent flange for cracks or gaps. Reapply appropriate RV roof sealant as necessary to prevent water leaks.
• Electrical Connections: Periodically inspect all electrical connections for corrosion or loose wiring. Ensure connections are secure and free from moisture.
