To insure proper operation, the unit must be adequately supported and properly installed. It is important that
the fan is properly installed and maintained per the information in this manual so that material clearances are
maintained and potential ignition sources are minimized.
After the receiving and inspection has been completed, install the unit with the following guidelines:
1. Installation of the fan (which may include the motor) is completed by the operator. When installing the
equipment, please make sure that the moving parts on the inside of the equipment are not accessible.
2. Move the Kice Fan to the installation area using proper equipment with sucient lifting capacity. The
fan has locations where the equipment necessary for lifting the device can be attached. These will
be the lifting lugs on the fan assembly frame. Lifting the fan at any other point is hazardous and may
compromise human safety as well as the structural integrity of the fan itself. Note: Motor lifting lugs
are not suitable lifting points.
3. Tighten all fasteners securely. Refer to the table of recommended hardware torque values in this
manual (Section 7) when performing Kice Fan installation.
4. The fan, as well as any other parts and equipment, must be separately grounded when assembled to
mitigate the risk of an electrostatic charge. If necessary, shaft grounding systems may be used.
5. To insure proper operation, all ductwork or stacks should be independently supported as excess
weight may distort the fan housing and cause contact between moving parts. Ductwork should also
be placed away from access routes and steps.
6. For proper operation, Kice fans should also be installed in such a manner as to provide normalized
inlet airflow to minimize noise and resulting vibration which results from inlet air turbulence.
7. The unit should only be operated once it is properly connected and fully encapsulated. The fan wheel
is built into the case and the case has two connections for the air inlet and air outlet.
8. If there is danger of vibration transfer to adjoining plant components, suitable compensators can be
installed on the air outlet transition. Where vibration isolators are used, consult Kice Industries, Inc.,
for proper location and adjustment.
9. The motor controls and starter can be mounted in any convenient location. Distance or location of the
controller does not aect its performance.
10. Electrical conduit, junction tees, safety switches, motor starters and sometimes motors, are not
furnished by Kice Industries, Inc. A local electrician familiar with industrial equipment and local codes
should install the electrical items. Wiring from the controls to the motor and switches should be sized
for the amperage rating on the electrical device. All electrical components must be in accordance
with current guidelines and codes.
11. Some systems will have additional equipment to wire and check. All items must be checked to insure
proper direction of rotation.
12. Test-run the fan. If any unusual noises or vibration occurs, disconnect and lock-out the power. Open
the equipment, manually rotate the rotor and inspect for touching or rubbing. The fan outlet must
remain free and clean at all times; otherwise dangerous operating conditions may occur, causing
damage to equipment and/or personnel.
13. Reassemble items removed during inspection and remove lock-out for operation.

Kice Industrial Fans are tested and adjusted before commissioning to validate design and operational
requirements as a final quality assessment. Each rotor has been dynamically balanced during fabrication to
conform to Kice vibration standards. Kice fan wheels are unique in that the wheel utilizes a hub with a split
taper bushing to insure concentric placement on the shaft and to insure that the wheel will retain its balance
(See the Fan Maintenance section for installation instructions).
It is not always practical for the manufacturer to perform a final assembly test run for vibration levels.
Therefore, though the impeller may have been balanced by the manufacturer, the customer is not assured of
a smooth-running assembled fan until the drive and/or driver are connected to the fan shaft and the unit is
tested for start-up vibration. Kice also cannot be responsible for the eects of vibration of drive components
added after factory test run and shipment.
S-U
Safe operation and maintenance includes the selection and use of appropriate safety accessories for the
specific installation. This is the responsibility of the system designer and requires consideration of the
equipment location and accessibility, as well as adjacent components. All safety accessories must be
installed properly prior to start-up.
Safe operating speed is a function of air temperature and wheel design. Do not, under any circumstances,
exceed the maximum safe fan speed published in the Kice Fan Performance bulletin, which is available from
Kice Industries, Inc. Kice fan performance characteristic curves and fan speed guidelines can also be found
on our website at http://www.kice.com/Product-CentrifugalFans.html .

1. Inspect the installation prior to starting the fan. Check for any loose items or debris that could be
drawn into the fan or dislodged by the fan discharge.
2. Check the tightness of all setscrews, nuts and bolts. When furnished, tighten hub setscrews or bolts
to the proper torque.
3. Install all remaining safety devices and guards. Verify that the supply voltage is correct and wire the
motor. “BUMP” the starter to check for proper wheel rotation, following all safetly protocols.
4. Test the unit for start-up vibration levels.
5. Use extreme caution when testing the fan with the ductwork disconnected. Apply power and check
for unusual sounds or excessive vibration. If either exists, see the Troubleshooting section of this
manual. To avoid motor overload, do not run the fan for more than a few seconds if the ductwork is
not fully installed. Check for correct fan speed and complete the installation. Ductwork and guards
must be fully installed for safety.
If a problem is detected, SHUT THE FAN DOWN IMMEDIATELY. Lock out the electrical supply. Check
carefully for the cause of the trouble and correct as necessary.
After a brief period of operation (even if the fan appears to be operating satisfactorily), shut down the
fan, lock out the electrical supply and recheck the following items:
1. Check and tighten all fasteners.
2. Check all setscrews tighten as necessary.
3. Properly secure all safety guards.

4. Secure all access doors to the fan housing and the ductwork.
The fan may now be put into operation. However, during the first eight hours of operation, it should be
periodically observed and checked for excessive vibration and noise. At this time, checks should also be
performed on the motor input current and the motor temperatures to insure that they do not exceed the
manufacturer’s recommendations.
After eight hours of satisfactory operation, the fan should be shut down and the power locked out in order to
check the following items and adjust if necessary:
1. Check and tighten all fasteners.
2. Check all setscrews and tighten as necessary.
3. Properly secure all safety guards.
After twenty-four hours of satisfactory operation, the fan should be shut down, observed and checked for
excessive vibration and noise again.
5. FAN MAINTENANCE
Kice fans are manufactured to high standards with quality materials and components. Proper maintenance
will ensure a long and trouble free service life.
Do not attempt any maintenance on a fan unless the electrical supply
has been completely disconnected and locked out. In many cases,
a fan wheel can windmill despite the removal of all electrical power.
The rotating assembly should be blocked securely before attempting
maintenance of any kind.
The key to good fan maintenance is regular and systematic inspection of all fan parts. Inspection frequency
is determined by the severity of the application and local conditions. Strict adherence to an inspection
schedule is essential. Regular fan maintenance should include the following:
1. Regularly check all components that can corrode, and as a consequence result in contact between
rotating parts and fixed parts.
2. Check the fan wheel for any wear or corrosion, as this can cause catastrophic failures. Check also for
the buildup of material that can cause the wheel to be unbalanced, resulting in vibration, bearing wear
and serious safety hazards. Clean or replace the wheel as required.
NOTE: Shut the fan down immediately if there is any sudden increase in fan vibration, fan noise or visible
deformation in the fan housing.
3. Hot surfaces and gaps between rotating parts must be regularly cleaned with a vacuum cleaner and/
or an antistatic cloth so that dust cannot deposit on the housing and create a potential ignition source.
4. When performing any fan maintenance, please refer to the table of recommended hardware
torque specifications (Section 7) when re-assembling equipment. For wheel hub bolt torque
recommendations, see the wheel hub bolt torque table in this section. All setscrews and bolts should
be checked for tightness during maintenance activity.
5. When installing a new wheel or inlet section, the proper wheel to inlet clearance must be maintained.
6. Any monitoring devices supplied with the fan (such as automated temperature and vibration
monitoring systems), need to be regularly inspected.
7. See the Illustrated Parts List (Section 8) in this manual for a detailed replacement part listing.
8. Maintenance intervals for Kice Fans vary depending on the fan application. Please contact Kice
Industries, Inc. for any further information regarding fan maintenance interval requirements.
Installation of a Kice fan wheel is dierent than most other fans because of the hub design. The Kice fan
wheel uses a hub with a split taper bushing to insure accurate placement on the shaft. Using a taper hub
and bushing insures that the fan wheel will be centered and the balance is the same as when it left the
factory.
Check the hub and bushing and remove all foreign material. Inspect the surfaces and edges to insure that
there are no burrs. Clean the machined surfaces of any grit or dirt and coat with a light film of oil. Place the
fan wheel onto the shaft inside the housing. Slide the bushing onto the shaft and into the hub. Slide the
wheel forward on the bushing and insert the bolts through the bushing flange into the three tapped holes in
the hub. Check the wheel clearances inside the housing.
Tighten each bolt in turn and then use a torque wrench to set each bolt to the proper torque (see page 15).
To insure that the bushing and hub are properly seated, tap the fan wheel hub with a hammer and then
retighten the bolts with a torque wench. In most instances, the bolts will tighten another few degrees.
Rotate the wheel and listen for any rubbing sound between the wheel and housing.

6. TROUBLESHOOTING GUIDE
Problem Probable Cause/Suggested Remedies
Excessive Vibration
A common complaint regarding
industrial fans is “excessive vibration”.
Kice Industries, Inc., is careful to
ensure that each fan is precisely
balanced prior to shipment; however,
there are many other causes for fan
vibration, including:
1. Loose mounting bolts or setscrews
2. Misaligned or unbalanced motor
3. Bent shaft due to mishandling or material impact
4. Accumulation of foreign material on wheel
5. Excessive wear or erosion of the wheel
6. Excessive system pressure or restriction of airflow due to
closed dampers
7. Externally transmitted vibration
Inadequate Performance
1. Fan wheel rotating in the wrong direction or installed
backwards on the shaft
2. Wheel not properly centered relative to the fan inlet
3. Damaged or incorrectly installed cuto sheet or diverter
4. Poor system design, closed dampers, air leaks, clogged filters
or coils
5. Obstructions or sharp elbows near the fan inlet
6. Sharp deflection of air stream at the fan outlet
Excessive Noise
1. Vibration originating elsewhere in the system
2. System resonance or pulsation (type of cavitation)
3. Improper location or orientation of fan discharge
4. Nearby sound reflecting o surfaces
5. Loose accessories or components
Premature component Failure
1. Prolonged or major vibration
2. Inadequate or improper maintenance
3. Abrasive or corrosive elements in the air stream or
surrounding environment
4. Misalignment or physical damage to rotating components
5. Excessive fan speed
6. Extreme ambient or air stream temperatures
7. TORQUE VALUES FOR MAINTENANCE
AND INSTALLATION
