Installation
Proper installation is critical for the fan's performance and longevity. Consult a qualified professional if you are unsure about any steps.
Tools and Materials Required:
- Standard hand tools (screwdriver, wire strippers, drill)
- Appropriate ducting (4.5-inch diameter)
- Sealant (radon-specific)
- Electrical wiring and connectors
- Mounting hardware
Installation Steps:
- Site Selection: Choose a location for the fan that is easily accessible for maintenance, protected from direct weather exposure, and allows for proper ducting runs. Ensure the location complies with local building codes for radon mitigation systems.
- Mounting: Securely mount the fan to a stable surface using appropriate mounting hardware. Ensure the fan is oriented correctly for airflow direction (indicated by arrows on the housing).
- Duct Connection: Connect the 4.5-inch ducting to both the inlet and outlet ports of the fan. Use flexible couplings to minimize vibration transfer. Ensure all connections are airtight using sealant or appropriate clamps.
- Electrical Wiring: Connect the fan to a dedicated electrical circuit. The fan operates on 12 Volts and uses a 3-Pin power connector. All wiring must be performed by a qualified electrician and conform to local electrical codes. Ensure proper grounding.
- System Sealing: After installation, thoroughly seal all cracks, openings, and penetrations in the concrete slab or foundation to prevent radon re-entry.
- System Testing: Once installed, power on the fan and verify proper operation. Check for any air leaks in the ducting or connections. Monitor radon levels to confirm system effectiveness.
Operation
The Fantech Radon Fan Rn1 is designed for continuous operation to maintain a negative pressure under your foundation, preventing radon gas from entering your living space.
- Once installed and powered, the fan operates automatically.
- No user intervention is typically required for daily operation.
- Ensure the power supply remains uninterrupted for continuous radon mitigation.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your radon fan.
- Annual Inspection: Annually inspect the fan and ducting for any signs of damage, wear, or leaks. Check electrical connections for security.
- Cleaning: If dust or debris accumulates on the fan blades or housing, disconnect power and carefully clean with a soft, dry cloth. Do not use liquid cleaners directly on electrical components.
- Noise Check: Listen for any unusual noises during operation, which may indicate a problem.
- Radon Level Monitoring: Periodically monitor radon levels in your home to confirm the system's continued effectiveness.
