General Safety Instructions
Warning:
Before installing or servicing, disconnect all power. Keep hands and body parts
clear of all moving parts when installing or servicing.
Read and follow all instructions, cautions and warnings. Failure to do so could result in
personal injury, death or property damage.
Electrical connections, installation and maintenance must be done by qualified
personnel in accordance with all applicable codes. Unit must be adequately grounded.
To reduce the risk of fire or electrical shock, do not expose this fan to water or touch
electrically live components.
Free rotation of the propeller is critical. It must not touch any part of the guard, shutter,
or opening framework.
Ensure that all power cords do not come in contact with any sharp edges, hot surfaces
or chemicals. Immediately replace any damaged cords.
Keep hands and body parts clear of all moving parts when installing or servicing.
Inspection
Fan Installation & Operation Tips
After unpacking your fan, carefully inspect for any damage that may have occurred
during transit. Inspect for loose, missing or damaged parts. If there is physical damage
to any parts of the fan, a freight claim must be filed with the carrier. Check to make
sure that all bolts, screws and set screws are securely tightened and have not become
loose during transit. Retighten as required.
Caution: Before operating your new fan, check blade for proper torque,
check all fasteners for tightness. Ensure fan blade is not obstructed.
For exhaust opening dimensions, refer to rough-in opening dimensions shown in the
specifications table in this manual.
Position the fan for desired airflow. Refer to fan mounting orientation in this manual.
Ensure the fan is fastened securely to the wall to avoid excess “rattling” or vibration.
Fasteners not included.
Refer to motor nameplate for wiring diagram.
Ensure that the area in front of and behind the fan is clear of any objects that may inter-
fere with airflow.
Shutter louvers must open and close freely.
Adequate intake air must be available to the fan for proper exhausting of air.
Check for excessive vibration while fan is running. If excessive vibration is noticed,
refer to troubleshooting chart in this manual.
When using speed controls on the variable speed capable models, it is recommended
to operate at no less than 50% of line voltage. Controls sold separately.
Variable speed controls should be installed by a qualified electrician.
“-TH” models include thermostat.

Periodic maintenance and component cleaning schedules should be set to assure
reliability and performance of the fan.
Periodically inspect and tighten all set screws and hardware—check torque on prop.
Assure all mounting hardware remains properly secured.
Motors feature permanently sealed ball bearings and require no further lubrication.
Note: Please contact the dealer/distributor where you purchased the fan from
with any questions regarding the fan, the manual or replacement parts.
