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

GENERAL SAFETY INFORMATION (CONTINUED)

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)

The special-purpose or dedicated parts, such as mounting fixtures,

must be used if such parts are provided.

For general ventilating use only. Do not use to exhaust hazardous or

explosive materials and vapors.

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.

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

present.

Duct length, elbows and other factors increase static pressure which can hinder the performance of most ventilation

fans. These products utilize SmartFlow™ 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.
