WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR 

INJURY TO PERSONS, OBSERVE THE FOLLOWING: 

1. Use this unit only in the manner intended by the manufacturer.

If you have questions, contact the manufacturer at the address 

or telephone number listed in the warranty.

2. Before servicing or cleaning unit, switch power off at service

panel and lock the service disconnecting means to prevent

disconnecting means cannot be locked, securely fasten a 

prominent warning device, such as a tag, to the service panel.

3. Installation work and electrical wiring must be done by a

qualified person(s) in accordance with all applicable codes 

and standards, including fire-rated construction codes and 

standards.

4. Sufficient air is needed for proper combustion and exhausting

of gases through the flue (chimney) of fuel burning equipment 

to prevent backdrafting. 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.

5. When cutting or drilling into wall or ceiling, do not damage

electrical wiring and other hidden utilities.

6.  Ducted fans must always be vented to the outdoors.
7. 

Use only ON/OFF switch, mechanical timer or relay-switched 
control.

8. Acceptable for use over a tub or shower when connected to

a GFCI (Ground Fault Circuit Interrupter) - protected branch

circuit.

9.  This unit must be grounded.

The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and en-

ergy use of the fan. Use the shortest, straighest duct routing possible for best performance, and avoid 

installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce en-

ergy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated airflow.

6-inch round rigid metal duct is recommended for best performance.
