4. Installation

The Fantech PB270L10V-2 is designed for remote mounting, allowing for quiet operation by positioning the fan motor away from the living area. This system utilizes a Y-adapter to connect two ceiling grilles to a single fan unit.

4.1 Pre-Installation Checks

• Ensure the installation location complies with local building codes and electrical regulations.
• Verify that the power supply is 120V, 1PH.
• Confirm adequate space in the attic or joist space for the fan unit, ductwork, and grille housings.
• Plan the ducting runs to be as straight and short as possible to maximize airflow efficiency.

4.2 Fan Unit Mounting

1. Select a suitable remote location for the fan unit, typically in an attic or utility space, away from the bathroom.
2. Securely mount the fan unit to a sturdy structural member using appropriate fasteners. Ensure the unit is level.

4.3 Ducting Connections

1. Install the two grille housings in the desired ceiling locations. These should be positioned directly over areas requiring ventilation, such as showers, whirlpool tubs, or toilets.
2. Connect 4-inch or 6-inch ductwork from each grille housing to the Y-adapter. Use duct clamps or tape to ensure airtight connections.
3. Connect the single output of the Y-adapter to the inlet of the Fantech fan unit.
4. Connect the exhaust outlet of the fan unit to exterior venting using appropriate ductwork. Ensure the exhaust duct terminates outside the building, away from windows or air intakes.
5. Minimize bends and kinks in the ductwork to maintain optimal airflow.

4.4 Electrical Wiring

1. Ensure power is OFF at the circuit breaker before beginning any wiring.
2. Route 120V electrical wiring to the fan unit and to the grille housing with the LED light, if separate wiring is required for the light.
3. Connect the fan unit wiring according to the wiring diagram provided with the unit and local electrical codes.
4. Connect the LED light wiring within the grille housing. Install the 14-watt LED bulb into the designated socket.
5. All electrical connections must be secure and properly insulated.

4.5 Grille Installation

1. Once ducting and wiring are complete, attach the decorative grilles to their respective housings in the ceiling.
2. Ensure the grilles are flush with the ceiling surface for a clean finish.

5. Operation

The Fantech PB270L10V-2 bath fan system is designed for straightforward operation.

5.1 Fan Operation

The fan unit is typically controlled by a wall switch (not included). Flip the switch to the 'ON' position to activate the fan. The fan will begin to draw air from both grille locations, exhausting it to the outside. The remote-mounted design ensures quiet operation within the living space.

5.2 LED Light Operation

The 10W LED light integrated into one of the grilles is also controlled by a separate or combined wall switch. Turn the switch to 'ON' to illuminate the area. The LED bulb provides instant-on illumination.

5.3 Continuous Operation

This fan is designed for continuous operation to meet ASHRAE Standard 62.2, which specifies minimum ventilation rates for indoor air quality. Consult local building codes for specific requirements regarding continuous ventilation.

4. Wipe down the interior of the grille housings to remove any dust or debris.

6.2 Fan Unit Inspection

Periodically (e.g., annually), inspect the fan unit in the attic or utility space:

• Turn off power to the fan at the circuit breaker.
• Check for any accumulation of dust or debris on the fan blades or motor housing. If necessary, gently clean with a soft brush or vacuum.
• Inspect duct connections for any leaks or disconnections. Re-secure with duct clamps or tape if needed.
