Panasonic FV-0511VHL1

This document outlines the operating and installation instructions for the Panasonic Fan Heater, models FV-0511VH1 and FV-0511VHL1. It emphasizes safety precautions, installation procedures for both new construction and retrofits, operational guidelines, and maintenance instructions.

Function Description

The Panasonic fan heater utilizes a sirocco fan driven by a DC motor, powered by an integral transformer. This design ensures a long operating life, high dynamic response, higher speed ranges, and energy efficiency. The fan heater is equipped with a 1600W PTC (Positive Temperature Coefficient) heater, which provides quick and efficient warming, particularly suitable for bathrooms. A thermostat and thermal cut-off switch are integrated for safety, preventing abnormal temperature rise.

For ventilation, the unit incorporates Smart Flow microchip technology. This technology monitors static pressure within the duct system and adjusts the fan's RPM accordingly, ensuring the fan performs as rated despite varying duct lengths, elbows, and other resistance factors. This feature helps avoid potential installation issues and ensures optimal ventilation performance.

The FV-0511VHL1 model also includes a lighting unit with a 10W LED light, offering illumination comparable to a standard 40W incandescent light. It also features a night light function, consuming approximately 0.1 to 0.4W. This model is Type IC-inherently Protected.

Usage Features

Operating Modes: The fan heater offers several operating modes:

"Heat" Mode: Heats the bathroom.
"Vent" Mode: Ventilates the bathroom.
"Heat" and "Vent" Mode: Exhausts moisture while simultaneously warming the bathroom.
"Light" Mode (FV-0511VHL1 only): Turns on the main LED light.
"Night-Light" Mode (FV-0511VHL1 only): Turns on the night light.

Pick-A-Flow™ Feature (Ventilating Mode Only): The fan heaters come with Pick-A-Flow™ speed options, allowing users to select between 50, 80, or 110 CFM (Cubic Feet per Minute) for constant air volume. The factory setting is 80 CFM. This switch is located on the face of the WhisperWarm® fan. Note that the Pick-A-Flow™ switch is not available to set ventilation air volume while operating in the heating and ventilating mode, as adequate ventilation is automatically provided to reduce heat loss in a bathroom.

Timer Function: A timer function is available for both "heating" and "heating and ventilating" modes. This feature automatically turns off the heat switch circuit after 2 hours if the user forgets to turn off the switch, thereby reducing power consumption. To reset the timer and resume operation, the "Heat" or "Vent" switch must be moved back to the "OFF" position.

Airflow Direction Adjustment: The orientation of the grille blades can be adjusted to direct the warm air flow as desired. Arrow marks on the grille blades indicate the direction of the warm air flow.

Quiet Operation: The blower utilizes a high-capacity sirocco fan developed to reduce noise levels.

Energy Efficiency: Built with DC motor technology, the fan's DC motor for ventilating is 30% - 70% more energy efficient than traditional AC motors.

Maintenance Features

Regular maintenance is crucial for the safe and efficient operation of the fan heater.

Filter Maintenance:

Frequency: The filter must be maintained every three months.
Removal: To remove the filter, squeeze the mounting spring and carefully pull down the specified side of the grille.
Cleaning: After removing the filter from the fan body, use a vacuum cleaner to remove dust and dirt.
Reinstallation: Insert the filter until it clicks, then reinstall the grille.

Grille and Fan Body Maintenance:

Frequency: The grille and fan body must be maintained every year.
Grille Cleaning: Clean the grille without submerging it in water. Use a non-abrasive kitchen neutral detergent, then wipe dry with a clean cloth. Ensure the grille is completely dry before reinstallation.
Fan Body Cleaning: Remove dust and dirt from the fan body using a vacuum cleaner. Afterward, use a cloth dampened with a non-abrasive kitchen neutral detergent to remove any remaining dirt, then wipe dry with a clean cloth.
Grille Removal for Cleaning: Similar to filter removal, squeeze the mounting spring and pull down the specified side of the grille to access the fan body.
Reinstallation: After cleaning, reinstall the grille.

Safety Precautions During Maintenance:

Always disconnect the power source at the circuit breaker panel and ensure it is locked to prevent accidental power-on before servicing or cleaning.
Ensure heating elements and the lighting unit are cool before handling.
Wear gloves during installation and maintenance procedures.
Never use gasoline, benzene, paint thinner, or other harsh chemicals for cleaning.
Do not immerse the motor or heater in water. Avoid soaking resin parts in water hotter than 140 °F (60 °C).
Do not insert fingers or foreign objects into the heating elements.
Unauthorized modification, repair, or disassembly is strictly prohibited. Any maintenance beyond user-level tasks should be performed by a specialized serviceman.
Mount the grille carefully to avoid pinching lead wires.
