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 with-
in 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 ELECTIC SHOCK OR
INJURY TO PERSONS OBSERVE THE FOLLOWING.
a) Use this unit only in the manner intended by the manufacturer. If
you have any question, contact the manufacturer.
b) Before servicing or cleaning 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 disconnect-
ing 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 stan-
dards, 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 manufactur-
er’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 elec-
trical 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 largest diameter ducting is used (5” or 6”). The length of
ducting and the number of elbows should be kept to a minimum.
As well to protect against condensation problems use insulated
ducting. Hard ducting will provide maximum air delivery – if using
flexible ducting always ensure it is pulled as tight as possible. Using
a short section of flexible ducting in combination with hard ducting
will reduce noise transmission.
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 fans wiring via the external wire com-
partment 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 hex flange nuts.
MOUNTING THE HOUSING
Select the best location to mount the housing in the ceiling. This fan
will require at least 8” of clearance in the ceiling will mount through
drywall up to
3
/4” thick. The fan housing can be mounted between
16” or 24” on center joists using the supplied 4 fan mounting rails.
Figure 2 shows housing installation between 16” or 24” on center
joists. Figure 3 shows housing installation directly to the joist (16”
on center).
If the fan is installed in a suspended ceiling installation and mount-
ing the fan from above is required, install the 4 fan mounting rails
onto the fan housing. Pushed the rails in as tight as possible.
Ensure the ends of the 4 mounting rails are evenly spaced from the
edge of the housing. Use galvanized ceiling wire secured to the per-
manent ceiling and to the 4 mounting rail ends. Adjust the fan
height so the housing will be flush with the finished ceiling.
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 num-
ber of elbows and duct length to a minimum.
1. Determine the best location for the fan.
2. Select the most convenient electrical knockout and remove it.
