3. Installation
Proper installation is crucial for the performance and longevity of your FANTECH PBW110F fan. Consult a qualified professional if you are unsure about any steps.
3.1 Mounting Location
- Select an exterior wall or roof location that allows for direct ducting from the area to be ventilated.
- Ensure the mounting surface is structurally sound to support the fan's weight (approximately 12 pounds).
- Maintain adequate clearance around the fan for airflow and future maintenance.
3.2 Ducting
- Use 4-inch diameter rigid or semi-rigid ducting for optimal performance. Flexible ducting should be kept as straight and taut as possible to minimize airflow resistance.
- Minimize duct length and the number of elbows to ensure maximum airflow.
- Seal all duct connections with duct tape or mastic to prevent air leakage.
3.3 Electrical Connection
- Turn off power at the circuit breaker before proceeding.
- Route appropriate electrical wiring (e.g., 14 AWG) to the fan's junction box.
- Connect the fan's wires to the building's electrical supply wires according to the wiring diagram provided inside the fan's junction box cover. Ensure proper grounding.
- Secure all connections with wire nuts and replace the junction box cover.
- The fan is designed for 120V AC, 60Hz power supply.
4. Operation
The FANTECH PBW110F fan is designed for continuous or intermittent operation. It is typically controlled by a wall switch (not included) or a remote control (if applicable to your setup, though the product specifications mention a remote control type, the fan itself may be wired to a standard switch).
- To activate the fan, turn on the connected wall switch.
- To deactivate the fan, turn off the connected wall switch.
- For optimal moisture removal in bathrooms, operate the fan during and for at least 15-20 minutes after showering or bathing.
5. Maintenance
Regular maintenance ensures efficient operation and extends the life of your fan. Always disconnect power before performing any maintenance.
5.1 Cleaning the Fan Blades and Housing
- Turn off power to the fan at the circuit breaker.
- Carefully remove any exterior grille or cover, if present.
- Using a soft cloth dampened with mild soap and water, wipe down the fan blades and interior/exterior housing.
- Do not allow water to enter the motor or electrical components.
- Allow all parts to dry completely before reassembling and restoring power.
5.2 Motor Lubrication
The fan motor is permanently lubricated and requires no additional oiling.
