10. Use this unit in the manner intended by the manufacturer. If you have any questions please call
the manufacturer .Customer service number located on last page.
11. Installation work must be carried out by qualified person(s) in accordance to all local and safety
codes including the rulers for fire-rated construction.
12. Sufficient air supply is required for proper combustion and the exhausting of gases through the
chimney(flue) of fuel burning equipment to prevent back –drafting .See the standards of NFPA
(National Fire Protection Association ) and ASHRAE(American Society for Heating Refrigeration
and Air Conditioning Engineers) and the local building code authorities.
13. Exercise care to not damage existing wiring when cutting or drilling into walls or ceilings.
14. Fans should always be vented to the exterior.
15. If this ventilating fan is installed over a tub or shower, it must be marked as approved for the

power from being turned on. If the panel cannot be locked clearly mark the panel with a warning
tag not to turn on the power.
17. Do not install in a ceiling with insulation greater than R40.
18. Ductwork should be installed in a straight line with minimum bends.
19. Duct work size must be a minimum of the discharge and should not be reduced.
UNPACKING
Unpack and carefully remove unit from carton.
Refer to the supplier Accessories list to verify that all parts are present.
20.

Safety Information (Continued)
WARNING: Not suitable for use as a range hood or
in areas where hazardous or explosive vapors are
present.
WARNING: FOR USE IN NON FIRE-RELATED
INSTALLATIONS ONLY.
WARNING: FOR USE IN ONE-AND-TWO FAMILY
DWELLINGS ONLY.
NOTE: Make sure the duct work size is a minimum
of the discharge. Do not reduce. Reducing the duct
size can increase fan noise.
CAUTION: Do not install in locations where the air
temperature will exceed 104°F (40°C).
IMPORTANT: You may want to consult with a
professional electrician regarding the wiring of your
ventilation fan.
IMPORTANT: Exercise care to not damage
existing wiring when cutting or drilling into walls or
ceilings.
CAUTION: For general ventilating use only. Do not
use to exhaust hazardous or explosive materials
and vapors.
NOTE: Ensure the insulation around and over the
fan body is properly installed to minimize building
heat loss and gain.

Pre-Installation
INSTALLATION OPTIONS
We recommend installing the ventilation fan by securing the main body of the fan against one ceiling joist and using the
header bars as necessary for support of the adjoining joist.
There are multiple installation configurations possible for this ventilation fan. Not all configurations are shown. If your
installation requires a variation other than those shown, consult with a licensed contractor to determine the best
installation for your project. If you are replacing an existing fan, ensure that the new grill will adequately cover the
existing opening.
PLANNING FOR SUCCESSFUL
INSTALLATION
When installing the ventilation fan in a new
construction site, install the main body of the fan and
duct work during the rough‑in construction of the
building. The grill should be installed after the finished
ceiling is in place.
When installing in existing construction, use the
dimensions on page 10 to determine the required hole
size for the ceiling. The grill edges should overlap the
finished ceiling.
NOTE: If installing in existing construction, you must
have access to space above and below the installation
location.
The unit will operate most quietly and efficiently when
located where the shortest possible duct run and
minimum number of elbows will be needed.
Do not install the ventilation fan in areas where the
duct work will require configurations as shown in the
following figure:
Recommended ductwork lengths should be 2-3 foot
straight run before elbow.
Short piece of flexible duct helps alignment and
absorbs sound.

1 Determining joist width
□ Measure the distance from the center of the two
ceiling joists where you will be installing the
ventilation fan.
2 Suspension bracket installation
□ For ceiling joist installations between 20 in. and 24
in., insert suspension brackets I (C), II (D), and III
(E). Proceed to step 3.
NOTE: Sliding hanger bars are provided to allow for
accurate positioning of the main body between joists.

□ Use long wood screws (AA) to loosely attach the
main body of the fan to one ceiling joist.
□ Extend the hanger bars to the opposite ceiling joist.
□ Secure the suspension brackets (C, D, and E) to
the joist using long wood screws (AA).
□ Ensure the main body is level and square to the
joists.
□ Tighten all screws.
CAUTION: Do not mount the fan flush against the joist. The

Care and Cleaning
□ Before servicing or cleaning the unit, disconnect the
power supply at the panel and lock to prevent the
power from being turned on. If the panel cannot be
locked, clearly mark the panel with a warning tag
to prevent the power from being turned on.
□ Remove the grill by squeezing the springs and
pulling the grill down.
□ Wash and clean the grill in a sink and dry with a
cloth.
□ Remove dust and dirt from the fan housing with a
vacuum cleaner.
□ Dampen the cloth with dish detergent, wipe the fan
housing and dry with a cloth.
□ Replace the grill.
□ To reduce the risk of fire, always vent fans to the
exterior and in compliance with local codes. Do
not vent exhaust air into spaces within walls,
ceilings, attics, crawl spaces, or garages.
□ Unplug or disconnect the appliance from the
power supply before servicing.
CAUTION: Do not use solvents, thinner or harsh
chemicals for cleaning the fan.
CAUTION: Do not allow water to enter the motor.
CAUTION: Do not immerse resin parts in water
over 140°F (60°C).
