- Keep hands, clothing, and other objects away from moving parts during operation.
- This fan is for indoor use only, specifically for attic and whole house ventilation.
- Do not use this fan with any solid-state speed control device unless specifically designed for this type of fan.
Setup and Installation
Proper installation is crucial for the performance and safety of your whole house fan. The fan is designed for easier installation, often without the need to cut ceiling joists.
Installation Requirements:
- Rough Opening: A rough opening of 27-3/4 inches by 29 inches is required in the ceiling for the fan and automatic shutter assembly.
- Attic Ventilation: Ensure your attic has at least 864 square inches of open exhaust vents. Insufficient attic ventilation can reduce fan efficiency and potentially cause damage.
- Electrical Connection: The fan operates on 110V. Wiring should be done by a qualified professional.
Components Overview:
The fan assembly typically consists of the fan motor and blades mounted within a frame, and a separate automatic louvered shutter. The shutter is white and designed to open when the fan is operating and close when it is off, preventing heat loss or gain.
General Installation Steps (Consult a professional):
- Prepare the Opening: Create the 27-3/4" x 29" rough opening in the ceiling where the fan will be installed.
- Position the Fan: Place the fan unit in the attic directly over the prepared opening. Secure it to the ceiling joists or a sturdy frame. The design often allows for installation without cutting joists.
- Install the Shutter: From below, install the automatic louvered shutter into the ceiling opening, ensuring it is flush with the ceiling surface.
- Electrical Wiring: Connect the fan to a 110V power supply. The fan includes a 2-speed pull chain control. Ensure all wiring is secure and compliant with electrical codes.
- Seal Gaps: Seal any gaps around the fan and shutter assembly to prevent air leakage and maximize efficiency.
Operating Instructions
The Air Vent 24-inch Whole House Fan is operated using a simple pull chain control, offering two speed settings.
How Whole House Fans Work:
A whole house fan draws cooler outside air into your home through open windows and doors, pushing hot, stale indoor air up into the attic and out through attic vents. This creates a comfortable breeze and rapidly cools your home.
Operating the Fan:
- Open Windows: Before turning on the fan, open several windows throughout your home. The more windows you open, the less concentrated the airflow will be through each, leading to a gentler breeze and more widespread cooling. Opening fewer windows will create a stronger breeze in specific areas.
- Turn On: Locate the pull chain extending from the fan's automatic shutter. Pull the chain once to turn the fan on to the first speed setting (typically low).
- Adjust Speed: Pull the chain again to switch to the second speed setting (high). Pulling it a third time will turn the fan off.
- Automatic Shutter: The white louvered shutter will automatically open when the fan is operating and close when the fan is turned off.
- Optimal Use: Use the fan during cooler parts of the day, such as evenings and mornings, to draw in cool air and flush out accumulated heat.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your Air Vent Whole House Fan.
- Power Disconnection: Always disconnect power to the fan at the circuit breaker before performing any maintenance.
- Cleaning: Periodically inspect and clean the fan blades and motor housing to remove dust and debris. Use a soft cloth or brush. Do not use harsh chemicals or abrasive cleaners.
- Shutter Inspection: Check the automatic louvered shutter for smooth operation. Ensure no debris is obstructing the louvers from opening and closing fully. Clean the louvers as needed.
- Motor Lubrication: The fan motor is typically permanently lubricated and does not require additional oiling. Refer to the motor's specific instructions if available.
- Wiring Check: Annually inspect electrical connections for any signs of wear, fraying, or loose connections.
