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.
burning equipment to prevent back drafting. 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 of Heating, Refrigerating and Air-Conditioning Engineers
(ASHRAE) and the local code
authorities.
When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
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
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
connected to a GFCI (Ground Fault Circuit Interrupter) - protected branch circuit.
These models are UL listed for tub and shower enclosures.
If this product is no longer to be used, it must be removed from the ceiling to prevent it from falling.
Do not install with a method which is not approved in the instructions.
This product must be properly grounded.
Do not use this fan with any solid-state speed control device. Solid state controls may cause harmonic
distortion which can cause a humming noise in the motor.
Do not disassemble the unit for reconstruction. It may cause fire or electric shock.
The ceiling joist must be able to withstand a static load of at least five times the weight of the product.

Make sure that the electric service supply voltage is AC 120 V 60 Hz.
Do not install this ventilating fan in a location where the interior room temperature may exceed 104 °F (40 °C).
Follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the
Occupational Safety and Health Administration (OSHA).
CAUTION
Always disconnect the power source before working on or near the fan, motor or junction box.
Protect the supply wiring from sharp edges, oil, grease, hot surfaces,
chemicals or other objects.
Do not kink the supply wiring.
Not for use in cooking area. (Fig. A)

DESCRIPTION
These products 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.
These products are listed by UL under UL file No. E78414.
(RG-C811HA only)
This Panasonic ventilating fan model is equipped with a humidity sensor that turns on automatically when humidity
increases rapidly, or when humidity rises above a 30% - 80% relative humidity set-point. It is user-adjustable to
operate 0.5 ~ 60minutes after the sensors are no longer detected.

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.
These products 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:
This product comes with Pick-A-Flow™ speed
options. The Pick-A-Flow™ switch on the face of the product allows the
option to choose 80 or 110 CFM.
This product can run continuously or intermittently, depending upon the
needs of the owner.

Note:
1. The power switch should be left on at all times.
2. The product will also run when the humidity rises rapidly but does not reach the humidity trigger setting, and then stop after
the time delay.
3. The activation humidity settings on the dial are continuous from 30 %RH ~ 80 %RH.
4. The humidity detected by the sensor may differ from the value on your hygrometer.
5. The product may cycle on and off if the humidity is constantly near the trigger point. This can be addressed by raising
the humidity trigger setting on the dial.
6. The fan will run for 20 minutes when power switch is first turned on, regardless of the humidity sensor settings. After 20
minutes, the fan will return to sensor mode.
