General Safety Information
Only qualified personnel should install this unit.
Personnel should have a clear understanding of these
instructions and should be aware of general safety
precautions. Improper installation can result in electric
shock, possible injury due to coming in contact with
moving parts, as well as other potential hazards. Other
considerations may be required if high winds or seismic
activity are present. If more information is needed,
contact a licensed professional engineer before moving
forward.
1. Follow all local electrical and safety codes, as well as
the National Electrical Code (NEC), the National Fire
Protection Agency (NFPA), where applicable. Follow
the Canadian Electrical Code (CEC) in Canada.
2. The rotation of the wheel is critical. It must be free
to rotate without striking or rubbing any stationary
objects.
3. Motor must be securely and adequately grounded.
4. Do not spin fan wheel faster than max cataloged fan
rpm. Adjustments to fan speed significantly effects
motor load. If the fan RPM is changed, the motor
current should be checked to make sure it is not
exceeding the motor nameplate amps.
5. Do not allow the power cable to kink or come in
contact with oil, grease, hot surfaces or chemicals.
Replace cord immediately if damaged.
6. Verify that the power source is compatible with the
equipment.
7. Never open blower access doors while the fan is
running.
DANGER

Receiving
Upon receiving the product check to make sure all items
are accounted for by referencing the bill of lading to
ensure all items were received. Inspect each crate for
shipping damage before accepting delivery. Notify the
carrier if any damage is noticed. The carrier will make
notification on the delivery receipt acknowledging any
damage to the product. All damage should be noted on
all the copies of the bill of lading which is countersigned
by the delivering carrier. A Carrier Inspection Report
should be filled out by the carrier upon arrival and the
Traffic Department. If damaged upon arrival, file claim
with carrier. Any physical damage to the unit after
acceptance is not the responsibility of manufacturer.
Unpacking
Verify that all required parts and the correct quantity
of each item have been received. If any items are
missing report shortages to your local representative to
arrange for obtaining missing parts. Sometimes it is not
possible that all items for the unit be shipped together
due to availability of transportation and truck space.
Confirmation of shipment(s) must be limited to only
items on the bill of lading.
Handling
Units are to be rigged and moved by the lifting brackets
provided or by the skid when a forklift is used. Location
of brackets varies by model and size. Handle in such
a manner as to keep from scratching or chipping the
coating. Damaged finish may reduce ability of unit to
resist corrosion.
Storage
Units are protected against damage during shipment. If
the unit cannot be installed and operated immediately,
precautions need to be taken to prevent deterioration of
the unit during storage. The user assumes responsibility
of the unit and accessories while in storage. The
manufacturer will not be responsible for damage during
storage. These suggestions are provided solely as a
convenience to the user.
INDOOR
The ideal environment for the storage of units 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 between 30°F (-1°C) and
110°F (43°C) (wide temperature swings may cause
condensation and “sweating” of metal parts). All
accessories must be stored indoors in a clean, dry
atmosphere.
2
Make-Up Air
Remove any accumulations of dirt, water, ice or snow
and wipe dry before moving to indoor storage. To avoid
“sweating” of metal parts allow cold parts to reach room
temperature. To dry parts and packages use a portable
electric heater to get rid of any moisture build up. Leave
coverings loose to permit air circulation and to allow for
periodic inspection.
The unit should be stored at least 3½ in. (89 mm) off the
floor on wooden blocks covered with moisture proof
paper or polyethylene sheathing. Aisles between parts
and along all walls should be provided to permit air
circulation and space for inspection.
OUTDOOR
Units designed for outdoor applications may be stored
outdoors, if absolutely necessary. Roads or aisles for
portable cranes and hauling equipment are needed.
The fan should be placed on a level surface to prevent
water from leaking into the unit. The unit should be
elevated on an adequate number of wooden blocks so
that it is above water and snow levels and has enough
blocking to prevent it from settling into soft ground.
Locate parts far enough apart to permit air circulation,
sunlight, and space for periodic inspection. To minimize
water accumulation, place all unit parts on blocking
supports so that rain water will run off.
Do not cover parts with plastic film or tarps as these
cause condensation of moisture from the air passing
through heating and cooling cycles.
Inspection and Maintenance during
Storage
While in storage, inspect fans once per month. Keep a
record of inspection and maintenance performed.
If moisture or dirt accumulations are found on parts,
the source should be located and eliminated. At each
inspection, rotate the fan wheel by hand ten to fifteen
revolutions to distribute lubricant on motor. Every three
months, the fan motor should be energized. 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. Immediately remove the original rust preventive
coating with petroleum solvent and clean with lint-free
cloths. Polish any remaining rust from surface with
crocus cloth or fine emery paper and oil. Do not destroy
the continuity of the surfaces. Wipe clean thoroughly
with Tectyl® 506 (Ashland Inc.) or the equivalent.
For hard to reach internal surfaces or for occasional
use, consider using Tectyl® 511M Rust Preventive or
WD-40® or the equivalent.
REMOVING FROM STORAGE
As units are removed from storage to be installed
in their final location, they should be protected and
maintained in a similar fashion, until the equipment goes
into operation.

in the belt maintenance section). Check fasteners, set
screws and locking collars on the fan, bearings, drive
(XKSFB only), motor base and accessories for tightness.
WARNING
Disconnect and lock-out all power before performing
any maintenance or service to the unit. Failure to do
so could result in property damage and serious injury
or death.
SPECIAL EQUIPMENT REQUIRED
CAUTION
If any of the original wire must be replaced, the
replacement wire must have a temperature rating of
at least 105°C. Any wiring deviations may result in
personal injury or property damage. Manufacturer is
not responsible for any damage to or failure of the unit
caused by incorrect final wiring.
DANGER
High voltage electrical input is needed for this
equipment. This work should be performed by a
qualified electrician.
1. Determine the Size of the Main Power Lines:
The unit nameplate states the unit’s voltage and total
amps. The main power lines to the unit should be
sized accordingly.

1. Check the Voltage: Before starting the unit,
compare the supplied voltage, hertz, and phase with
the unit and motor nameplate information.
2. Check the Blower Rotation: Remove the housing
cover and run the blower momentarily to determine
the rotation. Arrows are placed on the blower scroll
to indicate the proper direction. If the blower is
rotating in the wrong direction, the unit will move
some air, but will not perform as designed. Be sure
to perform a visual inspection to guarantee the
correct blower rotation.
TO REVERSE ROTATION
To reverse the rotation, disconnect and lock-out the
power.
Single Phase:
Rewire the motor per the
manufacturer’s instructions.
Three Phase:
Interchange any two power leads.
3. Check for Vibration: Check for unusual noise,
vibration or overheating of the bearings and take
corrective action.
Excessive vibration may be experienced during
the initial start-up. Left unchecked, it can cause a
multitude of problems, including structural and/or
component failure.
Generally, fan vibration and noise is transmitted
to other parts of the building by the ductwork. To
minimize this undesirable effect, the use of heavy
canvas connectors is recommended.
4. Motor Check: Measure the motor’s voltage, amps
and RPM. Compare to the specifications. Motor
amps can be reduced by lowering the motor RPM or
increasing system static pressure.

5. Air Volume Measurement and Check: Measure
the unit’s air volume (cfm) and compare it with its
rated air volume. If the air volume is off, adjust the
belts and drives (XKSFB) or speed controller (XKSFD)
until the specified air volume is reached.
The most accurate method for measuring the air
volume is a pitot traverse method downstream of the
blower. Other methods can be used, but should be
proven and accurate.
WARNING
Changing the belts or drives can significantly increase
the amp draw of the motor. If changes are made to
the drives or belts, the amps must be checked to
assure no over-amping.
Aluminum mesh filters can be washed in warm soapy
water. An adhesive spray can be added to increase the
filter efficiency.
• Be sure to reinstall filters with the airflow in the
correct direction. An airflow direction arrow is
located on the side of the filters.
• Replacement filters should be from the same
manufacturer and be the same size as the original
filters provided with the unit.
Motors – Motor maintenance is generally limited to
cleaning and lubrication (where applicable).
Cleaning should be limited to exterior surfaces only.
Removing dust and grease build-up on the motor
assures proper motor cooling.
Motors supplied with grease fittings should be
greased in accordance with the manufacturer’s
recommendations.
Maintenance
WARNING
Disconnect and lock-out all power before performing
any maintenance or service to the unit. Failure to do
so could result in property damage and serious injury
or death.
V-Belt Drives (XKSFB only) – V-belt drives
must be checked on a regular basis for wear, tension,
alignment and dirt accumulation. Check the alignment
by using a straight edge across both sheaves and
the tension by measuring the deflection in the belt as
shown.
Deflection = Belt Span
64
• Greasing of motors is only intended when fittings are
provided. Many fractional horsepower motors are
permanently lubricated and will not require additional
lubrication.
CAUTION
Do not allow water or solvents to enter the motor or
bearings. Under no circumstances should motors or
bearings be sprayed with steam, water or solvents.

• Improper belt tension and/or misaligned sheaves
lead to premature and frequent belt failures.
• Do not pry belts on or off the sheave. Loosen belt
tension until belts can be removed by gently lifting
them off of the sheaves.
• When replacing V-belts on multiple groove drives,
all belts should be changed to provide uniform drive
loading.
• Do not install new belts on worn sheaves. If the
sheaves have grooves worn in them, they must be
replaced before new belts are installed.
Wheels – Wheels require little attention when moving
clean air. Occasionally, oil and dust may accumulate
on the wheel causing imbalance. When this occurs the
wheel and housing should be cleaned to assure proper
operation.
Filters – Filter maintenance is generally limited to
cleaning and replacement. The filters in the unit should
be inspected at least every three (3) months. Depending
on the environment, filters could require changing or
cleaning more or less often.
