Receiving
Upon receiving the product, check to ensure all
items are accounted for by referencing the delivery
receipt or packing list. Inspect each crate or carton
for shipping damage before accepting delivery. Alert
the carrier of any damage detected. The customer
will make a notation of damage (or shortage of items)
on the delivery receipt and all copies of the bill of
lading which is countersigned by the delivering
carrier. If damaged, immediately contact your local
representative. 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
Fans 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
the ability of the fan to resist corrosion. Fans should
never be lifted by the fan housing, motor, motor cover,
windband or accessories.
Storage
Rotate propeller monthly and purge bearings once
every three months.
Energize fan motor once every three months.
Store belts flat to keep them from warping and
stretching.
Store unit in a location which does not have
vibration.
After storage period, purge grease before putting
fan into service.
If storage of fan is in a humid, dusty or corrosive
atmosphere, rotate the fan and purge the bearings
once a month. Improper storage which results in
damage to the fan will void the warranty.
Fans 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 fan 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
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 between 30° to 110°F
(-1° to 43°C), wide temperature swings may cause
condensation and “sweating” of metal parts. All
accessories must be stored indoors in a clean, dry
atmosphere.
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 remove any moisture
buildup. Leave coverings loose to permit air circulation
and to allow for periodic inspection.
The unit should be stored at least 3½ inches
(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 - Fans 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 fan. The fan should be
elevated on an adequate number of wooden blocks
so 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 fan parts on
blocking supports so 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 propeller by hand ten to
fifteen revolutions to distribute lubricant in motor and
bearings. 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. Thoroughly

Removing from Storage
As fans are removed from storage to be installed
in their final location, they should be protected and
maintained in a similar fashion until the fan equipment
goes into operation.
Prior to assembly and installation of the unit and
system components, inspect the fan assembly to
make sure it is in working order.
1. Check all fasteners, set screws on the fan,
propeller, bearings, drive, motor base and
accessories for tightness.
2. Rotate the fan propeller by hand and assure no
parts are rubbing.
3. Fans should not be lifted by the fan housing,
motor, motor cover, windband or accessories.

General Information
Guards – Motor Cover or Inlet Guard
Do not operate fans without proper protective devices
in place. Failure to do so may result in serious bodily
injury and property damage. Check local codes to
ensure compliance for all protective devices.
Inspection Door
Before opening the inspection door, ensure the fan
propeller has stopped moving and that the propeller
has been secured from being able to rotate. Do not
operate fan without inspection door in its fully closed
position.
Air Pressure and Suction
In addition to the usual hazards associated with
rotating machinery, fans also create a dangerous
suction at the inlet. Special caution needs to be used
when moving around a fan, whether it is in operation
or not. Before start-up, make sure the inlet area is
clear of personnel and loose objects.
To ensure a successful installation, the instructions in
this manual should be read and adhered to. Failure to
comply with proper installation procedures may void
the warranty.
Unit and System Identification Tags
Each fan has a permanently affixed manufacturer’s
engraved metal nameplate containing the model
number and individual serial number.
The tag shown is an example of an identification
nameplate on the fan. The information provides
general details about the fan, as well as containing
specific information
unique to the unit.
When contacting
your local
manufacturer’s
representative with
future needs or
questions, have the information on this label available.
Tags are mounted in an area which is clearly visible,
usually on the side of the fan housing.
Pre-Installation Information
Before installation, it is important to be certain the
mounting surface will bear the operating weight of the
fan. For proper fan operation, it is also important that
it be operated in a completely level position.
For further details on safety practices involving
industrial and commercial fans, please refer to AMCA
Publication410.
Electrical Disconnects
All fan motors should have disconnects located in
close visual proximity to turn off electrical service.
Service disconnects shall be locked-out when
maintenance is being performed.
Moving Parts
All moving parts must have guards to protect
personnel. Refer to local codes for requirements
as to the number, type and design. Fully secure fan
propeller before performing any maintenance. The fan
propeller may start “free wheeling” even if all electrical
power has been disconnected. Before the initial start-
up or any restart, check the following items to make
sure that they are installed and secure.
Do not spin fan propeller faster than the maximum
cataloged fan RPM.
Adjustments to fan speed significantly affects
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.
NOTE
For units supplied or used with a Variable Frequency
Drive (VFD), reference the VFD documentation
for installation requirements, start-up settings,
parameter adjustments and trouble shooting. VFDs
provided by Greenheck are factory programmed
for basic motor parameters, incoming voltage
parameters and maximum operating speed (Hz).
Follow NEC and local codes for VFD wiring and
installation. If the wire length between the VFD and
the controlled motor exceeds 100 ft (30.5 m), DV/DT
filters or VFD cabling may be required. Calculations
and proper application of DV/DT filters and VFD
cabling is by others; failing to do so may result in
premature motor failure.

Fans – Rigging and Lifting
IMPORTANT
Fans should never be lifted by the housing, motor,
motor cover, windband or accessories.
1. Before lifting, be sure that all shipping materials
have been removed from the fan.
2. Use standard lifting and rigging practices.
3. ALL lifting brackets on each fan must be utilized at
the same time.
4. Fan to be kept level during lifting and installation.
5. Spreader bars are recommended and must span
the fan to prevent damage to the damper section
of the fan by the lifting cables.
6. Always test-lift the fan to check for proper balance
and rigging before hoisting to desired location.
7. Never lift fan in windy conditions.
8. Preparation of roof opening should be completed
prior to lifting fan to the roof.
9. Carefully lift the fan to the roof curb and install
fasteners in all holes provided in the unit base.
The windband need not be removed for the lifting
operation.
Fans are to be rigged and moved by the lifting
brackets shown in Figure 1 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 fan to resist corrosion. See coating repair
section of this manual for details regarding touch-up
of damaged surfaces.
The electrical supply must be compatible with the
fan motor voltage, phase and amperage capacity.
The electrical supply line must be properly fused and
conform to local and national electrical codes.
For direct drive units, the electrical supply may
be routed internally and exit through a hole provided
in the fan housing if an optional service disconnect
switch is provided.
For belt drive units, the electrical supply line
may be routed internally and exit the fan housing
through a hole provided below the belt tube opening.
The electrical supply line should then be either: (1)
connected to an optional service disconnect switch,
or (2) wired directly to the motor.
For belt drive units in continuous high
temperature installations, the electrical supply
must be kept out of the airstream. This means
bringing the supply lines off the roof deck not through
the fan. The electrical supply line should then be
either: (1) connected to an optional service disconnect
switch, or (2) wired directly to the motor.
For belt drive units in emergency smoke
removal installations, the electrical supply must
be kept out of the airstream. They may also require
an isolated power supply so that if power is cut to the
building in the event of a fire, the fan will continue to
operate. Check the local and national electrical codes
for emergency smoke removal fans.

Additional Steps for Initial Start-Up
FASTENERS - Check all fasteners and set screws for
tightness. This is especially important for bearings
and propellers. Rotate the propeller by hand to assure
it turns freely and does not rub on the fan tube. Also,
lift the butterfly dampers to check if they open and
close without binding.
PROPELLER ROTATION - Direction of propeller
rotation should be checked by turning the unit on
momentarily. Rotation should be in the same direction
shown on the rotation
decal affixed to the
unit. To reverse
rotation on three
phase installations,
simply interchange
two of the three
electrical leads.
For single phase
installations, follow
the wiring diagram
located on the motor
nameplate.
FAN RPM - For belt drive units, the adjustable
motor pulley is preset at the factory to the customer
specified RPM. Fan speed can be increased or
decreased by the adjusting the pitch diameter of the
motor pulley. Multi-groove variable pitch pulleys must
be adjusted an equal number of turns open. Always
check the motor amperage reading and compare it to
the amperage rating shown on the motor nameplate
when changing fan RPM.
Unit Start-Up
WARNING
Disconnect and secure to the OFF position all
electrical power to the fan prior to inspection
or servicing. Failure to comply with this safety
precaution could result in serious injury or death.
DANGER
Pour écarter les risques de blessure grave ou
de mort, débrancher et verrouiller l’alimentation
électrique en position « Arrêt » avant tout contrôle
ou entretien.
Visual Inspection of Equipment
The equipment type and arrangement should be
verified as ordered at once when it arrives at the
jobsite. When a discrepancy is found, the local
representative must be notified immediately so
that corrective action may be investigated. Verify
electrical conformance to specifications. Unauthorized
alterations and unauthorized backcharges will not be
recognized by manufacturer.
After the fan has been installed and all utilities have
been hooked up, the unit is ready for operation.
Check
Before starting the fan, check the following:
1. Confirm that building supply voltage matches the
voltage for which the unit is wired.
2. Check all piping and wiring penetrations made by
contractors for water tightness. All penetrations
must be made watertight to prevent water
damage to the unit and building.
3. Rotate the fan propeller manually to be sure that
it is free to operate. Remove any dirt or debris
that may have accumulated during installation.
4. Check the fan bearing setscrews for tightness.
5. Check alignment of sheaves and V-belts. See
Belt Drive Maintenance section.
6. Inspect all fasteners to ensure that none have
loosened during shipment.
7. Check flex coupling for proper alignment and
connect between motor shaft and fan shaft
(direct drive).
8. Check all guarding to ensure that it is securely
attached and not interfering with rotating parts.
9. Check all electrical connections for proper
attachment.
10. Check housing and ductwork, if accessible,
for obstructions and foreign material that may
damage the fan propeller.
Rotation
Actual direction of rotation
will vary by model
Electrical Connections
Before electrical connections are made, the supply
voltage, phase and ampere capacity must be checked
for compatibility with the fan motor. In addition, the
supply wiring must be properly fused and conform
to local and national electrical codes. If the unit is
supplied with a safety disconnect switch, ensure
proper wiring to the fan motor. Be sure the disconnect
is switched to the “OFF” position before connecting
supply wires. If no disconnect is supplied, ensure the
supply wire is not live before connection. Supply wires
are then connected to the optional safety disconnect
switch (if supplied) or motor.

Routine Maintenance and Operation
WARNING
Disconnect and secure to the “OFF” position
all electrical power to the fan prior to inspection
or servicing. Failure to comply with this safety
precaution could result in serious injury or death.
DANGER
Pour écarter les risques de blessure grave ou
de mort, débrancher et verrouiller l’alimentation
électrique en position « Arrêt » avant tout contrôle
ou entretien.
Once the fan has been put into operation, periodic
maintenance should be scheduled to assure reliability
and performance. The following items should be
checked as a part of this maintenance schedule:
Motors
Motor maintenance is generally limited to cleaning
and lubrication. Cleaning should be limited to exterior
surfaces only. Removing dust and grease buildup
on the motor housing assists proper motor cooling.
Never wash down motor with high pressure spray.
Greasing of motors is only intended when fittings are
provided. Many fractional motors are permanently
lubricated for life and require no further lubrication.
Motors supplied with grease fittings should be
greased in accordance with the manufacturer’s
recommendations. When motor temperature does not
exceed 104ºF (40ºC), the grease should be replaced
after 2000 hours of running time.
Direct drive systems have extended grease lines to
lubricate the motor without removal of any guarding.
Fasteners and Set Screws
Normal fan vibration has a tendency to loosen
mechanical fasteners. Periodic inspection should
include checking all fasteners and set screws,
including the propeller fasteners, for tightness.
Direct Drive Fans
LUBRICATION - Lubrication of motors is intended
only when fittings are provided. Many fractional
horsepower motors are permanently lubricated and
require no further lubrication. Motors supplied with
grease fittings should be greased in accordance with
the manufacturers directions on the motor nameplate.
Belt Drive Fans
BEARINGS - Bearings are one of the most critical parts
of a fan and should be inspected at regular intervals.
Locking collars, set screws and fasteners attaching
the bearings to the fan should also be checked.
LUBRICATION - Bearings operating in a clean
environment and temperatures between 32°F and
200°F should be lubricated semiannually using a
high quality lithium based grease. Those operating
outside these temperatures require special high or low
temperature grease. If contamination or high moisture
conditions exist, more frequent lubrication is required.
Models TAUB-CA and TAUB are equipped with
extended lubrication lines as standard. The grease
fittings are located on the exterior of the fan housing
next to the motor cover and should be wiped clean
before adding grease.
When adding grease to the fan bearings, rotate the
fan shaft while slowly operating the manual grease
gun. Be careful not to unseat the bearing seals by
over lubricating or using excessive pressure. Stop
pumping when a very slight resistance is felt at the
grease gun.
Lubrication of motors is intended only when fittings
are provided. Many fractional horsepower motors
are permanently lubricated for life and require no
further lubrication. Motors supplied with grease
fittings should be greased in accordance with the
manufacturer’s directions on the motor nameplate.
BELTS - V-belt drives must be checked on a
regular basis for wear, tension, alignment and dirt
accumulation. Premature or frequent belt failures can
be caused by improper belt tension (either too loose
or too tight), misaligned pulleys or by prying belts on
and off pulleys. Abnormally high belt tension or drive
misalignment will cause excessive bearing loads and
may result in failure of the fan and/or motor bearings.
Conversely, loose belts will cause squealing on start-
up, excessive belt flutter, slippage and overheated
sheaves. Either excessively loose or tight belts may
cause fan vibration.
When replacing V-belts on multiple groove drives,
all belts should be changed to provide uniform drive
loading. Do not pry belts on or off the sheave. Loosen
belt tension until belts can be removed by simply
lifting the belts off the sheaves. After replacing belts,
ensure that slack in each belt is on the same side of
the drive. Belt dressing should never be used.
Fan Operation
All fans should be run every thirty (30) days, or at least
“bumped” every thirty days. It is preferred that each
fan is run as this causes all electrical and mechanical
components to get up to temperature, displacing any
formed condensation, redistributes load on bearings,
and redistributes grease in the motor and shaft
bearings.
IMPORTANT
When operating conditions of the fan are to be
changed (speed, pressure, temperature, etc.),
consult manufacturer to determine if the unit can
operate safely at the new condition.
Tube Axial Upblast Fans 9
®
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.
The proper tension for operating a V-belt is the lowest
tension at which the belts will not slip at peak load
conditions. Belts are adjusted by raising or lowering
the motor pivot plate. For initial tensioning, the proper
belt deflection is 1/64in. for each inch of belt span,
measured half
way between the
pulley centers.
For example, if
the belt span is
64inches, the belt
deflection should
be 1inch using
moderate thumb
pressure at mid-
point of the drive.
Check belt tension two times during the first
24hours of operation and periodically thereafter.
REMOVAL OF DUST AND DIRT - Model TAUD,
TAUB-CA and TAUB fans require very little
attention when moving clean air. If exhausting dirty
or contaminated air, the propeller and butterfly
damper assembly should be cleaned periodically.
Accumulations of dirt and debris on the propeller
blades may cause an unbalanced condition resulting
in excessive vibration and premature failure of the
propeller and bearings. Excessive buildup of dirt on
the damper blades may cause binding and sticking
blade hinges resulting in loss of fan performance.
Periodically, the motor cover on TAUB-CA and TAUB
fans should be removed and the motor cleaned of dirt
and debris. Cleaning of the motor on all fans should
be limited to the exterior. Removal of dust and dirt
from the motor will assist in motor cooling. Motors
should never be sprayed directly with water, steam or
solvents.
V-Belt Replacement
The V-belt drive components, when supplied by
Greenheck, have been carefully selected for this
unit’s specific operating condition. Changing V-belt
drive components could result in unsafe operating
conditions which may cause personal injury or failure
of fan components.
1. Remove the protective coating from the end of the
fan shaft using mineral spirits or another similar
solvent. Check to ensure that the shaft is free of
nicks and burrs.
2. Slide sheaves on shafts. Do not drive sheaves on
as this may result in bearing damage.
3. Align fan and motor sheaves with
a laser, straight-edge or string
and tighten.
4. Place belts over sheaves.
Do not pry or force
belts, as this could
result in damage to the
cords in the belts.
5. Adjust the tension until
the belts appear snug.
Run the unit for a few
minutes (refer to unit start-up section) and allow
the belts to “set” properly.
6. With the fan off, adjust the belt tension by moving
the adjustable motor plate. (Belts are adjusted
by raising or lowering the motor plate). When in
operation, the tight side of the belts should be in
a straight line from sheave to sheave with a slight
bow on the slack side.
Do not force belt(s). Forcing the
belt(s) will break the cords and
cause belt failure

FANFAN
MOTOR MOTOR
Aligning Sheaves
with a Straight Edge
The adjustable motor pulley is set at the factory for
the fan RPM specified by the customer. Fan RPM can
be increased by closing or decreased by opening the
adjustable motor pulley. Multi-groove variable pitch
pulleys must be adjusted an equal number of turns
open or closed. Any increase in fan speed represents
a substantial increase in load on the motor.
To avoid motor overheating and possible burnout,
motor load amperes should always be checked and
compared to nameplate rating when fan speed is
increased.
Alignment of Pulleys and Belts
Check pulleys and belts for proper alignment to avoid
unnecessary belt wear, noise, vibration and power
loss. Motor and drive shafts must be parallel and
pulleys in line as shown.
NOTE
Model TAUB may require high temperature belts.

Variable Frequency Drive
Operation
For operation with a variable frequency drive (VFD)
always check motor amps when adjusting the
operating frequency. Motor may be sized for the
original selected operating speed under 60 Hz.
Bypassing the VFD or increasing the speed from this
original selection, even if less than 60 Hz, may cause
motor to overload or fail. Consult factory with fan
serial number before increasing the upper limiting
frequency.
Always check the fan RPM when adjusting the
operating frequency. Do not exceed maximum class
fan RPM of the propeller.
NOTE
It is the responsibility of the installing body to
perform coast-down tests and identify any resonant
frequencies after the equipment is fully installed.
These resonant frequencies are to be removed
from the operating range of the fan by using the
“skip frequency” function in the VFD programming.
Failure to remove resonant frequencies from the
operating range will decrease the operating life of
the fan and void the warranty.
Field Coating Touch-Up Procedure
for Scratched Areas
Standard coating and color is RAL 7023 Concrete
Grey. This procedure outlines the correct method for
repairing minor scratches in the coating.
1. Scuff affected area to be repaired using medium
sandpaper (provided) or medium Scotch Brite™
pad. Feather the edges.
2. Clean affected area to be touched up using an
alkaline based cleaner and rinse.
3. Apply Kem Kromik® primer using 1 inch foam
brush (provided). Follow technical data sheet
instructions.
4. Allow primer to dry a minimum of 2-1/2 hours
before top coating.
5. Apply topcoat with industrial enamel using 1 inch
foam brush (provided). Follow technical data
sheets instructions. Allow painted units to air-dry
and cure before putting into service. See Technical
Data sheets (included with kit) for detailed drying
and cure schedules at different temperatures.
To order coating repair kits please reference part
number HAZ2597 PNT FIELD REPAIR KIT, RAL7023
CONCRETE GREY. Please contact factory with your
fan’s serial number for colors other than our standard.
