READ AND SAVE THESE INSTRUCTIONS

Thank you for purchasing this Panasonic product.
Please carefully read the section “IMPORTANT SAFETY INFORMATION”.
Failure to comply with instructions could result in personal injury or property damage. Please
explain to users how to operate and maintain the product after installation and present this
manual to users. Please retain this manual for future reference.

IMPORTANT SAFETY INFORMATION

For your safety

To reduce the risk of injury, loss of life, electric shock, fire, malfunction, and damage to equipment or property,
always observe the following safety precautions.

Denotes a hazard that could result in property damage.

WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR INJURY TO PERSONS, OBSERVE
THE FOLLOWING:

Use this unit only in the manner intended by the manufacturer. If you have any questions, contact the
manufacturer.

Before servicing or cleaning unit, switch power off at service panel and lock the service disconnecting
means to prevent power from being switched on accidentally. When the service disconnecting means
cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel.

Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable
codes and standards, including fire-rated construction.

Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel
burning equipment to prevent backdraft. Follow the heating equipment manufacturer’s guideline and
safety standards such as those published by the National Fire Protection Association (NFPA), and the
American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) and the local code
authorities.

When cutting or drilling into wall or ceiling, do not damage electrical wiring or other hidden utilities.

Ducted exhaust fans must always be vented to the outdoors.

If this unit is to be installed over a tub or shower, it must be marked as appropriate for the application and
be connected to a GFCI (Ground Fault Circuit Interrupter) protected branch circuit.

Do not use replacement parts that have not been recommended by the manufacturer (e.g. parts made at
home using 3D printer).

This product must be properly grounded.

Do not use this unit with any solid-state speed control device. Solid state controls may cause harmonic
distortion which can cause a humming noise in the motor.

IMPORTANT SAFETY INFORMATION

Do not disassemble the unit for reconstruction. It may cause fire or electric shock.

Install the fan at least 1.5 m (5 feet) above the floor.

CAUTION

Follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the
Occupation Safety and Health Act (OSHA), using UL approved wire nuts.

Make sure that the electric service supply voltage is AC 120V, 60Hz.

The special-purpose or dedicated parts, such as mounting fixtures, must be used if such parts are
provided.

Please wear gloves to protect hands during installation.

Do not install this ventilating fan where interior room temperature may exceed 104°F (40°C).

For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.

Do not kink the supply wiring.

NOTICE

Provide make up air for proper ventilation.

Do not connect multiple units in parallel. If two or more units are connected to one switch in parallel, the
unit may not function.

Do not install fan above or inside 45-degree angle projected outwards from the cooking equipment element
closest to fan (Fig. A).

Do not install the unit where ducts are configured as shown (Fig. B).

PLEASE READ PRIOR TO INSTALLING THIS FAN

Continuous ventilation: These fans are designed to run continuously ensuring a healthy environment at low CFM
levels 24 hours a day. By utilizing the optional Multi-Speed module, the fans are built to run continuously at a
pre-set lower level (FV-0511VKS3S, FV-0511VKS3 and FV-0511VK3: 0, 30, 40, 50, 60, 70, 80, 90, 100
CFM; FV-1115VK3: 0, 50, 60, 70, 80, 90, 100, 110, 120 CFM). The setting is dependent on the size of the
house and the individual wishes of the homeowner. It is crucial that the installer pre-sets the lower setting
during the installation. Please refer to the chart below and Multi-speed module on page 8.

Spot ventilation: These fans are also built to take care of the homeowner’s spot ventilation needs when the room
is occupied. The basic fan models allow a choice of three speeds. When fans are equipped with the optional
Multi-Speed module, these models increase to a maximum level of 150 CFM for the FV-1115VK3 and 110 CFM
for FV-0511VKS3S, FV-0511VKS3 and FV-0511VK3 either when the switch is turned on, or activated by the
optional Condensation Sensor module (FV-CSVK1) or the optional Motion Sensor module (FV-MSVK1).

A High/Low Delay Timer, located inside the fan unit, is utilized to return the fan back to the pre-set continuous
ventilation mode. The installer needs to consult with the homeowner for the desired setting on the timer (0 - 60
minutes) and make the adjustments during the installation.

DESCRIPTION

This product use a sirocco fan driven by a DC motor powered by an integral transformer. The motor is designed
to have long operating life, high dynamic response, higher speed ranges and energy savings.The grille covering
the fan body is a spring-attached, quick removal type. A damper for preventing air counter flow is provided.
The blower uses a high-capacity sirocco fan developed to reduce the noise level.

UNPACKING

Unpack and carefully remove the unit from packing.
Refer to the Supplied Accessories list to verify that all parts are present.

FEATURES

Optimum ventilation performance:

Duct length, elbows and other factors increase static pressure which can hinder the performance of most
ventilation fans. This fan utilizes Smart Flow microchip technology that monitors the static pressure in the
system and speeds up or slows down the RPM of the fan depending upon the amount of resistance within the
ducts. This feature allows the fan to perform as rated and avoid potential installation issues.

Outstanding Energy Savings:

The WhisperGreen Select line of fans are built using DC motor technology. The DC motor is 30% - 70% more
energy efficient than the minimum ENERGY STAR requirements.

®

Pick-A-Flow Feature
All the WhisperGreen Select base models of fans come with Pick-A-Flow
speed options. The Pick-A-Flow switch on the face of all WhisperGreen Select

fans allows the option to choose 50 – 80 – 110 CFM for the FV-0511VKS3S,

These fans can run continuously or intermittently, depending upon the needs of
the owner.

FV-VS15VK1 Multi-Speed module allows the fan to run continuously at lower
speeds to maintain ventilation standards to meet Indoor Air Quality and then
boost up to high speed to meet intermittent needs for ‘Spot’ or ‘Point Source’
exhaust needs. The FV-VS15VK1 Modular Component will operate for both
the FV-0511VK3 and the FV-1115VK3 matching the appropriate Multi-Speed
setting shown below. Multi-speed module FV-VS15VK1 is included for models
FV-0511VKS3S and FV-0511VKS3. It is not necessary to purchase this component.
Note the options on the face of the FV-VS15VK1 Multi-Speed module to choose
appropriate levels of airflow (CFM) and time delay before returning back to low
speed (TIME). Choosing the Pick-A-Flow setting automatically adjusts the
Multi-Speed setting accordingly. As an example, if the Pick-A-Flow Multi-speed
setting is 80 CFM, the Multi-Speed settings adjust automatically to be 0, 30, 40,
50, 60 or 70 CFM at the lower speeds. The fan will ‘boost’ to the 80 CFM speed
as the high speed setting. Selecting a particular TIME option will cause the fan to
run for the selected amount of time before returning to the lower speed setting
chosen on the CFM dial.

PRACTICAL GUIDE TO INSTALLATION

1. The ducting has a strong effect on the air flow, noise and energy use of the fan. Use the shortest, straightest
duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended.
Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with
existing ducts may not achieve their rated airflow.

2.

A circular 6-inch duct is recommended for best performance and proper fan installation.

Ensure duct joints and exterior penetrations are sealed with caulk or other similar material to create an

3.
airtight path and to minimize building heat loss and gain and reduce the potential for condensation.

Place / wrap insulation around duct and / or fan in order to minimize possible condensation buildup within

4.
the duct, as well as minimize building heat loss and gain.

-4 inch or 6 inch roof jack, wall cap,
or soffit vent with backdraft damper

Mechanically connect duct to termination and seal

with mastic or approved foil faced tape* /

-2-3 ft straight run before elbow
