GENERAL SAFETY INFORMATION
WARNING: ROTATING PARTS & ELECTRICAL SHOCK
HAZARD
Fans should be installed and serviced by qualied personnel
only. Improper installation can result in electric shock,
possible injury due to coming in contact with moving parts, as
well as other potential hazards.
1. Follow all local electrical and safety codes, as well as
National Electrical Code (NEC) and the National Fire
Protection Agency (NFPA), were applicable.
2. Disconnect electric power before working on unit (prior to
removal of guards or entry into access doors).
3. Follow proper lockout/tag out procedures to ensure the
unit cannot be energized while being installed or serviced.
4. Ensure the power cable does not kink or come in contact
with oil, grease, hot surfaces or chemicals. Ensure the
power source is compatible with the equipment.
5. Air that is allowed to move through a non-powered fan will
allow the propeller to rotate, which is referred to as wind-
milling. Impellers should be blocked to prevent rotation
when installing or servicing the fan.
RECEIVING AND INSPECTION
Immediately upon receipt of a shipment, carefully inspect
for damage and shortage. Turn the impeller by hand to see
that it turns freely and does not bind. If any damage and/or
shortage is detected or suspected, the carrier must be asked
to conduct an inspection. The consignee’s representative
should not accept a shipment without a notation on the
delivery receipt indicating items not delivered or the apparent
extent of damage.
When a shipment is opened and damage is found which was
not evident externally (concealed damage), it is mandatory
that the consignee request an immediate inspection by the
carrier. Report any damage to the carrier within 15 days.
Failure to report damage within the above time limit will result
in rejection of a claim.
HANDLING
When handling fans and their accessories, always use
equipment and methods that will not cause damage. Fans
should be lifted using slings and padding or spreaders to
avoid damage.
CAUTION! Always make sure that all lifting and handling
equipment and techniques conform to current safety
standards.
Avoid lifting fans in a way that will bend or distort fan parts.
Never pass slings or timbers through the orices of fan.
CAUTION! Do not lift by the fan hood. Fans with special
coatings or paints must be protected in handling to prevent
damage.
STORAGE
Fans are protected against damage during shipment. If
they cannot be installed and put into operation immediately
upon receipt certain precautions are necessary to prevent
deterioration during storage. Responsibility for integrity of
fans and accessories during storage must be assumed by the
user. The manufacturer will not be responsible for damage
during storage. These suggestions are provided solely as a
convenience to the user, who shall make his own decision as
to whether to use any or all of them.
INDOOR: The ideal storage environment for fans and
accessories is indoors, above grade, in a low humidity
atmosphere which is sealed to prevent the entry of blowing
dust, rain, or snow. Temperatures should be evenly maintained
at between 70°F and 105°F (wide temperature swings may
cause condensation and “sweating” of metal parts). Windows
should be covered to prevent temperature variations caused
by sunlight. Provide thermometers and humidity indicators at
several points and maintain the atmosphere at 40% relative
humidity, or lower.
It may be necessary to use trays of renewable desiccant or
portable dehumidier to remove moisture from the air in the
storage enclosure.
Thermostatically controlled portable heaters (vented to
outdoors) may be required to maintain even temperatures
inside the enclosure.
CAUTION! Provide re extinguishers, or re alarms, or
emergency response communication to protect building and
equipment against re damage. Be sure that building and
storage practices meet all local, state and federal re and
safety codes.
The following fans or accessories must be stored indoors, in
a clean dry atmosphere:
a. Propeller wall fans not in wall housings.
INSTALLATION & MAINTENANCE INSTRUCTIONS
Models PVD
To include optional su󰀩xes:
EC-Electronically Commutated Motor, H-Hurricane Rated, HEC-Hurricane Rated with EC Motor

b. Any fan is protected by a cardboard carton.
c. Motors dismounted from fans.
d. Spare wheels or propellers.
e. Belts, sheaves, bushings and other parts when not
mounted on fan.
f. Boxes, bags or cartons of hardware.
g. Curbs
h. Dampers
Remove any accumulations of dirt, water, ice or snow and
wipe dry before moving indoor storage. Allow cold parts to
reach room temperature to avoid “sweating” of metal parts.
Open boxes or cartons. Remove any accumulated moisture;
if necessary use portable electric heaters to dry parts and
packages. Leave coverings loose to permit air circulation and
to permit periodic inspection.
Rotate wheels or propellers by hand to distribute bearing
grease over the entire bearing surfaces.
Store at least 3 ½” o󰀨 the oor on wooden blocks covered
with moisture proof paper or polyethylene sheathing. Provide
aisles between parts and along all walls, to permit air
circulation and space for inspection.
OUTDOOR: Fans designed for outdoor use may be stored
outdoors, if absolutely necessary. The storage area should
be reasonably level and drained or ditched to prevent
accumulation of water. Fencing and lighting for security are
desirable. Roads or aisles for portable cranes and hauling
equipment are needed. Consider the use of drift fencing to
minimize accumulation of blowing snow or dirt.
The following fans may be stored outdoors, if dry indoor
storage space is not available:
a. Fans intended for outdoor use that are crated in
wood.
b. Wall fans installed in wall housings.
All fans must be supported on wooden blocks or timbers
above water or normal snow levels. Provide enough blocking
to prevent settling into soft ground. Fans should be set in
place using the directional arrow markings on the crate as a
guide.
Locate pieces far enough apart to permit air circulation,
sunlight, and space for periodic inspection. Place all parts
on their supports so that rain water will run o󰀨, or to minimize
water accumulation. Do not cover parts with plastic lm or
tarps - these cause condensation of moisture from the air
passing through heating and cooling cycles.
Fan wheels and propellers should be blocked to prevent
spinning caused by strong winds.
INSPECTION AND MAINTENANCE DURING
STORAGE
Inspect fans and accessories at least once per month,
while in storage. Log results of inspection and maintenance
performed. A typical log entry should include the following:
a. Date
b. Inspector’s Name
c. Name of Fan
d. Location
e. Condition of Paint or Coating
f. Is moisture present?
g. Is dirt accumulated?
h. Corrective steps taken?
If moisture or dirt accumulations are found on parts, the
source should be located and eliminated. Fans should be
rotated at each inspection by hand ten to fteen revolutions to
redistribute the motor and bearing lubricant.
If paint deterioration begins, consideration should be given
to touch-up or repainting. Fans with special coatings may
require special techniques for touch-up or repair.
Machined parts coated with rust preventive should be restored
to good condition promptly if signs of rust occur. The most
critical items are pulleys, shafts and bearing locking collars.
At the rst sign of rusting on any of the above parts, remove
the original rust preventive coating with petroleum solvent and
clean lint-free cloths. Polish any remaining rust from surfaces
with crocus cloth or ne emery paper and oil. Do not destroy
the continuity of the surfaces. Wipe clean with lint-free cloths
and recoat surfaces evenly and thoroughly with a corrosion
preventative.
REMOVING FROM STORAGE
As fans are removed from storage to be installed in their nal
location, they should be protected and maintained in similar
fashion, until the fan equipment goes into operation.
BEFORE INSTALLING CHECK FASTENERS
INSTALLATION
1. CAUTION! This unit has rotating parts and safety
precautions should be exercised during installation,
operation and maintenance.
2. WARNING! Do not use in hazardous environments
where the fan’s electrical system could provide ignition
to combustible or ammable materials, unless the unit is
specically built for hazardous environments.
3. WARNING! If gases, other than clean air, are to be
exhausted using the fan, then the user bears the
responsibility of determining that the fan is appropriate
and safe for the application.
4. If the fan manufacturers prefab curb is used, a ange is
provided for mounting the damper. Damper should be
installed before setting exhauster.
5. If damper box is being used, assemble box and mount in
curb before setting exhauster. Damper may be installed
at this time if desired. Damper should be fastened to the
bottom of the damper box, curb anges or nailing strips in
curb.
6. Impeller Adjustment: Turn centrifugal impeller by hand to
make sure it rotates freely. If impeller hits orice, adjust
by loosening set screw in impeller hub and move impeller
back on motor shaft.
2
WARNING! Before installing and before starting, check
all fasteners/set screws for tightness, particularly in the
propeller/wheel hub, and fan shafts. Turn the propeller/
wheel by hand to make sure it rotates freely and that the
blades do not strike the orice. Failure to do so voids
the warranty as fasteners/set screws may come loose
in transit. See table recommended tightening torque
located in Maintenance section.

7. CAUTION! Guards must be installed when fan is within
reach of personnel or within eight (8) feet (2.5 m) of
working level or when deemed advisable for safety.
8. Remove the motor compartment cover (small hood).
CAUTION! Before proceeding, make sure electrical
service to fan is locked in “OFF” position. Run wires
through the internal wiring post to the motor, to disconnect
switch if used. WARNING! The wiring post is sealed to the
curb cap with a large washer and sealing gasket. If the
wiring post is loosened, the seal may be broken, thereby
creating a possible water leak.
9. All wiring should be in accordance with local ordinances
and the National Electric Code.
FOR EC Motor Wiring
Go to pages 5 through 11 on how to wire and setup a EC
motor.
10. WARNING! Check voltage being supplied to the fan to
see that it corresponds with the motor nameplate voltage;
high or low voltage can seriously damage the motor. On
multi-voltage motors, check motor terminal connections to
make sure motor is internally connected for voltage being
supplied. Motor wiring diagram is located on the side of
the motor or in the motor wiring compartment for ECM
motors go to back of this form for wiring diagrams. Extra
care should be taken when wiring two speed motors since
improper connections will damage motor and void motor
warranty.
11. Apply power momentarily and compare the rotation of
the impeller with the directional arrow on fan. WHEEL
ROTATION IS CLOCKWISE AS VIEWED FROM TOP
OF FAN. WARNING! Operation in the wrong direction
will deliver air but will overload the motor to the extent
of blowing fuses, overload protection and could seriously
damage the motor. In the case of single phase motors, the
reversing instructions will appear on the wiring diagram,
located either in the motor wiring compartment or on the
outside of the motor housing.
12. Using a minimum of eight (8) lag bolts - two (2) on
each side near corners, securely fasten fan to curb,
replace small hood and fasten all bolts securely. The
fan should rest on the curb as level as possible.
Over tightening the bolts can cause the inlet cap to distort
and push the inlet cone into the wheel.
MAINTENANCE
1. Under normal usage, no spare parts are recommended
for one year of operation. Recommended spare parts are
shown on page 4.
2. CAUTION! Before proceeding, make sure electrical
service to fan is locked in “OFF” position.
WINDMILLING: Even when the power is locked out, fans
may cause injury or damage if the impeller is subject to
“windmilling” which is the turning of the impeller and drive
components due to a draft in the system. To guard against
this hazard, the impeller should be secured to physically
restrict rotational movement.
3. Motor bearings are pre-lubricated. Consult information
printed on the motor for lubrication instructions.
4. If motor requires replacement, one comparable to the
original with the same service factor and enclosure must
be used.
SET SCREW TIGHTENING SCHEDULE
1. Before initial operation of the fan, tighten set screws
according to the procedure outlined below.
2. After 500 operating hours or three months, whichever
comes rst, tighten set screws to the full recommended
torque.
3. At least once a year, tighten set screws to the full
recommended torque.
PROCEDURE FOR TIGHTENING SET SCREWS IN
BEARINGS AND HUBS
One Set Screw Application
Using a torque wrench, tighten the set screw to the torque
recommended in Table 1.
Two Set Screw Application
1. Using a torque wrench, tighten one set screw to half of the
torque recommended in Table 1.
2. Tighten the second set screw to the full recommended
torque.
3. Tighten the rst set screw to the full recommended torque.
VARIABLE FREQUENCY
DRIVES AND MOTORS
There are occasions when a Variable Frequency Drive (VFD)
will cause poor motor performance and possible damage.
To avoid these problems, the Company recommends the
following:
1. Select compatible motor and VFD inverter; if possible,
the motor and the inverter should be from the same
manufacturer or at least the inverter selected should be
recommended by the motor manufacturer.
2. A motor shaft grounding system should be used to prevent
motor bearing damage from eddy currents.
NOTE: The Company will not honor motor warranty claims
if the customer fails to follow these recommendations.

PerfectSpeed®Motor and User Interface Troubleshooting
Motor Is Not Running
If the PerfectSpeed®motor with User Interface isn’t running, perform the following checks:
1. Ensure that both the PerfectSpeed®motor and User Interface have proper line voltage for intended application.
2. Turn the User Interface on-board potentiometer fully clockwise (100% demand) and check to see if the motor runs.
3. If 0-10 VDC input is in use, disconnect the external input from the User Interface and perform Check 2.
4. Check the digital read-out of User Interface for an error code:
Error Code Reason Action
E1 No Communication Remove power from both the PerfectSpeed®motor and User Interface for four (4)
minutes, then reconnect power and test again.
Check the communication cable connection between the PerfectSpeed® motor and
User Interface.
Check the continuity of communication cable (pin 1-1, pin 2-2 pin 3-4, and pin 4-3).
E2 Low Voltage This is a reading from the PerfectSpeed®motor itself. Ensure that there is at least 71
VAC (for 115 VAC applications) or 142 VAC (for 230 VAC applications).
E3 Not a NMC Motor Connect to a NMC motor.
Check 2: Electrical Troubleshooting
1. Disconnect or remove power to the equipment being
serviced and allow four (4) minutes for the capacitors to
discharge any residual voltage.
2. Check the rotation and speed of the motor. Determine if
the motor can spin freely by hand without e󰀨ort or assisted
means. If any binding occurs, replace the motor and control
unit.
3. Determine whether the system is wired for 120 VAC power
or 240 VAC power.
4. Disconnect the power cord from the connector on the
control unit. Inspect the power cord for bent, damaged, or
recessed wires and terminals.
5. Disconnect or remove AC power to the equipment serviced
and allow four (4) minutes for the capacitors to discharge
any residual voltage.
6. Proceed to Check 3.
Check 3: Motor Verication
1. Disconnect or remove AC power to the equipment serviced
and allow four (4) minutes for the capacitors to discharge
any residual voltage.
2. Make sure that the motor shaft spins freely by hand without
e󰀨ort in both directions.
3. DC motors can have a jump lling when rotating this is
perfectly normal, if motor does not rotate at all motor needs
to be replaced.
Final Checks of the Motor
1. Check the mounting and fastening of the motor and control
unit. Make sure the motor and the control unit are securely
attached together and mounted tightly in the system.
2. Check the control unit connectors. Inspect for shorts,
detached wiring, or loose connections.
3. Check the motor and verify the rotation of the driven load.
Make sure it spins freely by hand in both directions without
e󰀨ort or assisted means.
4. Check all circuit breakers.
