General Installation
CAUTION: Sheet metal parts, screws, clips and similar
items inherently have sharp edges, and it is necessary
that the installer and service personnel exercise caution.
The installation of this equipment shall be in accordance
with the regulations of authorities having jurisdiction and
all applicable codes.
This equipment is to be installed by an experienced
installation company and fully trained personnel. The
mechanical installation of the exhaust ventilator consists
of making final connections between the unit and building services.
CAUTION: Disconnect power and lock out power source
before installing or servicing. Failure to disconnect power
can result in electric shock, fire or serious injury.
1. Do not operate the fan beyond the maximum cataloged RPM. The current should be verified any time
the RPM is adjusted to ensure it is below the
nameplate amperage value.
2. Verify the equipment is compatible with the power source.
3. Allow motor to cool down before servicing to avoid
injury.
Receiving
When the equipment is received, all items should be
carefully checked against the bill of lading to ensure all
items have been received. Inspect each package for
shipping damage before accepting delivery.
If any damage occurred, notify the carrier, who will make
proper notation on the delivery receipt acknowledging
the damage. Damages should be noted on all copies of
the bill of lading and have all copies countersigned by
the delivering carrier. A Carrier Inspection Report should
be filled out and forwarded to the Traffic Department.
If units are damaged in transit, it is the responsibility of
the receiver to make all claims against the carrier. Twin
City Fan is not responsible for damages incurred during
shipment or after acceptance.
Short Term Storage
If fan installation is to be delayed, store the unit in a
protected area, preferably indoors. Protect fan bearings
and motor from moisture and vibration.
Long Term Storage
Prior to storage, grease fan bearings and motor bearings
per manufacturer's specifications. Note, motors which
contain ball bearings are permanently lubricated as built.
No additional lubrication is required. On belt drive units,
belts should be removed or at least the belt tension
reduced to prevent a sag/set from forming in the fan
shaft and belts. Rotate wheel and shaft monthly and
leave in a different position. When unit is to be removed
from storage and activated, check for corrosion and
damage. All bearing grease should be purged and
replaced with fresh grease.
Unpacking
Verify that all required parts and proper quantities have
been received for each item. Report shortages or missing items to your local representative to arrange for
replacement parts.
Sometimes it is not possible for all items to ship together due to availability of carriers and truck space.
Verification of shipments must be limited to only items
on the bill of lading.

Electrical Connection
Standard Fan
1. Connect supply wiring to the disconnect switch (nonfused standard).
2. The motor is factory set at the voltage marked on the
fan nameplate. Check the line voltage with the nameplate voltage.
3. The main power wiring should be sized for the ampacity shown on the dataplate. Size wires in accordance
with the ampacity tables in Article 310 of the National
Electrical Code. If long wires are required, it may be
necessary to increase wire size to prevent excessive
voltage drop. Wires should be sized for a maximum
of 3% voltage drop.
CAUTION: Use copper conductors only.
any two of the three line leads. If the unit is checked with
temporary wiring, it should be rechecked when permanently installed. Motor burn out or tripped overload protection devices are usually the result of wrong rotation.
6. Electrical Input Check: Perform check of fan ampere
draw and verify that motor nameplate amps are not
exceeded. Take into account the service factor of the
motor if it is above 1.0 S.F.
7. Fan RPM should be checked and verified with a
tachometer.
CAUTION: Protect wiring from sharp edges. Leave some
slack in the line to prevent damage.
4. Disconnect switches are not fused. The power leads
must be protected at the point of distribution in accordance with the fan dataplate.
5. All units must be electrically grounded in accordance
with local codes or, in the absence of local codes,
with the latest edition of the National Electrical Code
(ANSI/NFPA 70). A ground lug is provided as standard
in the unit terminal box. Size grounding conductor in
accordance with Table 250-95 of the National Electrical
Code. DO NOT use the ground lug for connecting a
neutral conductor.
6. Supply voltage to the power ventilator should not vary
by more than 10% of the value indicated on the unit
dataplate. Phase unbalance must not exceed 2%.
Check, Test & Start Procedures
Warning: Electric shock hazard. Could cause severe
injury or death. Failure to bond the frame of this equipment to the building electrical ground by use of the
grounding terminal provided or other acceptable means
may result in electrical shock. Disconnect electric power
before servicing equipment. Service to be performed only
by qualified personnel.
Before Start-up: Disconnect power before servicing unit

1. Check all fasteners and setscrews for tightness.
Note: The wheel position is set at the factory and the fan
was balanced and vibration tested prior to shipment.
Movement may have occurred during transport and realignment may be necessary.
2. Check that the wheel is centered and free to rotate.
Centering can be changed by loosening isolator
mounts and repositioning the drive frame.
3. For optimum fan performance make sure that the
wheel to inlet venturi gap or overlap is maintained per
Figure 7. Height can be adjusted by loosening set
screws on the wheel and reposition on the fan shaft,
per the table.
4. Verify that the power supply matches the voltage on
the fan data plate and is within the 10% utilization
rate.
5. Apply power to unit and check rotation of wheel with
the directional arrow on the unit. All fans are clockwise, as viewed from drive side, per Figure 8.
Warning: Rotation is critical. If allowed to operate in the
wrong direction, the motor will overload and burn out. For
three-phase units, rotation can be changed by switching
View from drive side

Inspection
Inspection of the fan should be completed at the first
30 minutes, 8 hour and 24 hour intervals of satisfactory operation.
30 Minute Interval
Inspect tightness of all hardware, setscrews and motor
mounting bolts. Adjust and tighten as necessary.
8 Hour Interval
Inspect belt alignment and tension. See Belt Adjustment
and tension as necessary
24 Hour Interval
Inspect belt tension, adjust as necessary.
Maintenance
A maintenance program should be established to maintain the reliability and performance of the fan. The
frequency of inspection depends on the location and
operating conditions of the fan.
Maintenance is to be performed only by qualified personnel who are familiar with local codes and regulations and experienced with this type of equipment.
Routine maintenance should cover the following:
a. Tighten all setscrews and hardware.
b. Check belt tension and sheaves for wear.
c. Lubricate fan bearings (see Table 4 for recom-
mended interval and Table 5 for grease types.
d. Cleaning of unit, wheel and grease box.
1. Before performing any maintenance on the fan, be
sure power is turned off and locked in the off
position at the service entrance.
2. Ventilators should be carefully checked at least
once a year. For critical or rugged applications, a
routine check every two or three months is suggested.
3. Always follow the bearing manufacturer's recom-
mended lubrication schedule. If not available, below
is a general guideline:
Table 4.
Bearing Greasing Intervals
Fan RPM Interval (months)
Up to 500 6
500 - 1,000 6
1,000 - 1,500 5
1,500 - 2,000 3
2,000 - 2,500 3
2,500 - 3,000 2
Divide the listed interval by 2 for vertical shaft applications or for 24 hour operation.
Relubricate while running, if safety permits, until some
purging occurs at seals. Adjust lubrication frequency
depending on condition of purged grease. Hours of
operation, temperature and surrounding conditions will
affect the relubrication frequency required.
4. All motors supplied with Twin City Fan & Blower
ventilators carry a one year limited warranty from
date of shipment. For repairs within the warranty
period, the motor must be taken to the motor man-
ufacturer's authorized service dealer. Contact your
TCF representative for additional warranty details.
5. A periodic motor check should consist of removing
the belt, then spinning the motor shaft with the
power off to be sure the motor turns freely and
the bearings run smoothly.
6. When removing or installing a belt, do not force
the belt over the sheave. Loosen the motor mount
so that the belt can be easily slipped over the
sheave. See Belt Adjustment, on page 8.
7. The belt should be removed and carefully checked
for glazing, cracks, ply separation or irregular wear.
A small irregularity in the contact surface of the
belt will result in noisy operation. If any defects are
apparent, the belt should be replaced.
8. Check sheaves for chipping, dents or rough surfaces which could damage the belt. Always replace
sheaves with identical size and type.
9. If the unit is left idle for an extended period, the
belts should be removed and stored in a cool, dry
place to avoid premature belt failure.
10. Check sheave setscrews to ensure tightness.
Proper keys must be in keyways.
11. Check for proper belt alignment. See Figure 10.
Improper alignment leads to excessive belt wear,
vibration, noise and power loss.
12. For two-groove drives, matched belts must be
used.
13. When replacing belts, use the same type & size as
supplied on the unit.
14. The standard pillow block bearings on belt driven
ventilators are factory lubricated and are provided
with external grease fittings. Lubrication bi-annually
is recommended, or more frequently if needed. (see
Table 5). It is recommended to add fresh grease
at start-up, but do not over-grease. Use only 1 or
2 shots of a recommended lubricant with a hand
gun in most cases (see Table 5). Maximum hand
gun rating of 40 psi. Rotate bearings during lubrication where good safety practice permits.
Caution: Greases of different soap bases (lithium,
sodium, etc.) may not be compatible when
mixed. Prevent such intermixing by completely purging the bearing of old greases.

15. The most frequent causes of bearing failure are not
greasing often enough, using an excessive quantity
of grease or using incompatible greases. Excessive
vibration, especially if the bearing isn't rotating, will
also cause bearings to fail. Bearings must also be
protected from water and moisture to avoid internal
corrosion.
16. During the first few months of operation, it is recommended to periodically check the bearing setscrews to ensure tightness.
17. Wheels require attention when moving dirty or
grease laden air. Regular cleaning is required to
avoid imbalance caused by accumulation of grease
or dust.
18. All fasteners should be checked for tightness during each maintenance.

is 1/64" multiplied by the center distance of sheaves (in
inches). (See Figure 11.)
Extreme care must be exercised when adjusting V-belts
as not to mis-align sheaves. Any misalignment will cause
a reduction in belt life and will increase the likelihood of
noise & vibration.
