IMPORTANT SAFEGUARDS
CAUTION : To reduce the risk of fire and to properly exhaust air, be
sure to duct air outside. Do not vent exhaust air into spaces within
walls or ceilings or into attics, crawl spaces, or garages.
WARNING: To reduce the risk of fire or electric shock, do not use
this fan with any solid-state speed control device.
WARNING - TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK
OR INJURY TO PERSONS OBSERVE THE FOLLOWING.
a) Use this unit only in the manner intended by the manufacturer. If
you have any questions, contact the manufacturer.
b) Before servicing or cleaning the unit, switch power to 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.
CAUTION - For general ventilating use only. Do not use to exhaust
hazardous or explosive materials and vapors.
WARNING - TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR
INJURY TO PERSONS, OBSERVE THE FOLLOWING:
a) Installation work and electrical wiring must be done by qualified
person(s) in accordance with all applicable codes and standards,
including fire-related construction.
b) Sufficient air is needed for proper combustion and exhausting of
gases through the flue (chimney) of fuel 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 for Heating, Refrigeration, and Air Conditioning Engineers
(ASHRAE), and the local code authorities.
c) When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.
d) Ducted fans must always be vented to the outdoors.
e) 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.
f) NEVER place a switch where it can be reached from a tub or
shower.
To ensure the best air and sound performance, it is recommended
that the length of ducting and the number of elbows be kept to a
minimum, and that insulated hard ducting be used. Larger duct
sizes will reduce noise and airflow restriction.
As an added convenience for installation, you do not have remove
the fan’s blower assembly in order to install and wire this unit; you
can gain access to the fan's wiring via the external wire
compartment, shown in fig. 1. If you choose to wire from inside the
fan housing, you will have to remove the fan’s blower assembly and
internal wiring compartment. The blower assembly is secured in
place with 2 nuts (8-32).
MOUNTING THE HOUSING
Select the best location to mount the housing in the ceiling. This fan
will require at least 10” of clearance in the ceiling or wall and will
mount through drywall up to
3
/4” thick. The fan housing can be
mounted between 16” on center joists using the two supplied fan
mounting brackets. Figure 1 shows housing installation on 16” on
center 2x4 joists. Figure 2 shows fan mounting bracket orientation
for mounting on 16” on center 2x6 joists (flip the fan mounting
brackets.). Figure 3 shows the installation to be used if you have
24” on center joists; you must install 2x4 headers (not supplied)
between joists, and install the fan mounting brackets on the front
and back of the housing. Before cutting or drilling into any drywall,
check the area from above to plan the unit’s wiring and duct run.
Remember to keep the number of elbows and duct length to a
minimum.
