Installation
Isolation Installation
To help prevent vibration and noise from being transferred to
the building, isolators are recommended.
Floor Mounted Spring Isolators
1. Mount fan on isolation base or rails (if supplied).
2. Elevate fan (or isolation base) to operating height and in-
sert blocks to hold in position.
3. Position isolators under the fan and vertically align by in-
serting leveling bolt through mounting holes in the fan or
the base. The isolator must be installed on a level surface.
4. Adjust the isolators by turning the leveling nut counter-
clockwise several turns at a time alternately on each iso-
lator until the fan weight is transferred onto the isolators
and the fan raises uniformly off the blocks. Then remove
the blocks.
5. Turn lock nut onto leveling bolt and secure firmly in place
against the top of the mounting flange or frame.
6. Secure isolators to mounting surface.

Floor Mounted Rubber-In-Shear (RIS) Isolators
1. Mount fan on isolation base or rails (if supplied).
2. Elevate fan to provide room to insert isolators between the
fan and foundation and block in position.
3. Position isolators under fan and secure bolts.
4. Remove blocks and allow fan to rest on floor. Isolators
must be installed on a level surface (leveling should not
be required).
5. Secure isolators to mounting surface.
Ceiling Mounted Spring and Rubber-in-Shear (RIS)Isola-
tors
1. Elevate fan to operating height and brace.
2. Attach threaded rod to overhead support structure directly
above each mounting hole. Rod should extend to within a
few feet of fan.
3. Attach isolator to end of threaded rod using a nut on each
side of isolator bracket.
4. Insert another section of threaded rod through the fan
mounting hole and isolator.
5. Attach two nuts to threaded rod in isolator.
6. Place adjusting nut and locking nut on threaded rod near
fan mounting bracket.
7. Alternately rotate adjusting nut at each mounting location
until the fan weight is uniformly transferred to the isolators.
Remove bracing.

Wiring Installation
Some fractional motors have to be removed in order to make
the connection with the terminal box at the end of the motor.
NOTICE! Follow the wiring diagram in the disconnect
switch and the wiring diagram provided with the mo-
tor. Correctly label the circuit on the main power box
and always identify a closed switch to promote safety
(i.e., red tape over a closed switch).
Direct Drive Fans
1. Pull the wire into the motor wiring box. Restrain the wire to
prevent it from being pulled into the shaft.
2. For final connections, follow the wiring diagram provided
on the motor.
Final Installation Steps
1. Inspect fasteners and setscrews, particularly fan mount-
ing and then tighten according to Recommended Torque
for Setscrews/Bolts.
2. Inspect for correct voltage with voltmeter.
3. Ensure all silencers, wire guards and accessories are
installed.
4. Check the fan to see if it is a directional or reversible prop.
5. For directional fans: Test the fan to be sure the rotation
is the same as indicated by the arrow marked Rotation.
For Reversible fans: Test the fan to ensure proper rotation
for the correct airflow direction.
NOTICE! Do not allow the fan to run in the wrong direc-
tion. This will overheat the motor and cause serious
damage. For 3-phase motors, if the fan is running in
the wrong direction, check the control switch. It is pos-
sible to interchange two leads at this location so that
the fan is operating in the correct direction.

Operation

Pre-Start Checks
1. Lock out all the primary and secondary power sources.
2. Inspect fasteners and setscrews, particularly those used
for mounting the unit, and tighten if necessary.
3. Inspect motor wiring.
4. Rotate the propeller to ensure it does not rub against the
housing.
5. Ensure fan, silencers, and wire guard are clean and free
of debris.
6. For directional fans: Test the fan to be sure the rotation
is the same as indicated by the arrow marked Rotation.
For Reversible fans: Test the fan to ensure proper rotation
for the correct airflow direction.Restore power to unit.
