Receiving and Inspection
Carefully inspect the fan and accessories for any dam-
age and shortage immediately upon receipt of the fan.
• Turn the propeller by hand to ensure it turns freely and
does not bind.
• Check dampers (if included) for free operation of all
moving parts.
• Record on the Delivery Receipt any visible sign of
damage.
Handling
Lift the fan by the base or by the shipping carton. Never
lift by the shaft, motor or housing.
If your fan is covered with a protective coating (e.g., phe-
nolic enamels, or other protective coatings), handle with
extreme care. Even a small chip will break the coating’s
continuity and destroy its ability to protect the metal.
Propellers are carefully balanced to give smooth, vibra-
tion-free operation. If the propeller is damaged during han-
dling, it will require rebalancing.
Storage
If the fan is stored for any length of time prior to installa-
tion, store it in its original shipping crate and protect it from
dust, debris and the weather.
Outdoor Storage
WARNING
This unit has rotating parts. Safety precautions
should be exercised at all times during installation,
operation, and maintenance.
ALWAYS disconnect power prior to working on fan.
REBEL/AQD/SEP
To maintain good working condition of the fan when it is
stored outdoors or at a construction site, follow the addi-
tional instructions below.
• Coat the shaft and bearings with grease or rust preven-
tative compound to help seal out moisture.
• Periodically rotate the propeller and operate the damp-
ers (if supplied) to keep a coating of grease on all inter-
nal bearing parts.
• Periodically inspect the fan to prevent damaging condi-
tions.
• Block propeller to prevent natural rotation.
• Cover the unit with some type of weather cover to pre-
vent moisture, corrosion, dirt or dust accumulation.
Installation
Damper Installation
If your fan is supplied with dampers, follow the directions
below. If your fan does not include dampers, proceed to
Motor Installation.
a. Place the damper inside the curb. Ensure the damper
will open freely for the correct direction of the airflow.
b. Secure to curb at the damper shelf by installing at least
two sheet metal screws (#10 x 1/2”) on each side of the
damper, through the tray, with the screw head catching
the flange on the damper. This will prevent the exhaust
dampers from lifting and keep the supply dampers cen-
tered.
c. Drill a hole in the curb shelf for conduit needed for
motor wiring.
Personal Safety
Disconnect switches are recommended. Place
the disconnect switch near the fan in order that
the power can be swiftly cut off in case of an
emergency, and in order that maintenance per-
sonnel are provided complete control of the
power source.
