result in personal injury and/or property damage.
TAUB
General Safety Information
Only qualified personnel should install this fan.
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 seismic
activity is 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) and the
National Fire Protection Agency (NFPA), where
applicable. Follow the Canadian Electric Code
(CEC) in Canada.
2. The rotation of the propeller 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 propeller faster than max
cataloged fan RPM. Adjustments to fan speed
with a Variable Frequency Drive (VFD) may affect
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 access doors to a duct while the fan is
running.
Always disconnect, lock and tag power source
before installing or servicing. Failure to disconnect
power source can result in fire, shock or serious
injury.
When servicing the fan, motor may be hot enough
to cause pain or injury. Allow motor to cool before
servicing.
Precaution should be taken in explosive
atmospheres.
Pour écarter les risques d'incendie, de choc
électrique ou de blessure grave, veiller à toujours
débrancher, verrouiller et étiqueter la source de
courant avant l'installation ou l'entretien.
Lors de toute intervention sur la soufflante, le moteur
peut être suffisamment chaud pour provoquer
une douleur voire une blessure. Laisser le moteur
refroidir avant toute maintenance.
Faire preuve de précaution dans les atmosphères
explosives.

Summarization of Contents
General Safety Information
Power Disconnection Safety
Always disconnect, lock, and tag power source before installing or servicing to prevent fire, shock, or serious injury.
Motor Cooling Caution
Allow motor to cool before servicing as it may be hot enough to cause pain or injury.
Explosive Atmosphere Precaution
Take precautions when working in explosive atmospheres.
Receiving, Unpacking, Handling, and Storage
Receiving Procedure
Inspect all items upon receipt for completeness and shipping damage before accepting delivery.
Unpacking Verification
Verify all required parts and correct quantities; report any missing items to the local representative.
Handling and Rigging
Rig and move fans using provided brackets or skid, handle carefully to avoid finish damage.
Storage Guidelines
Store fans indoors in a low humidity environment, above grade, and at stable temperatures.
Storage Inspection and Maintenance
Inspect fans monthly, rotate propeller, energize motor, and check for moisture or dirt accumulation.
Removing from Storage
Pre-Assembly Checks
Check fasteners, set screws, propeller rotation, and ensure no parts are rubbing before assembly.
General Information
Unit Identification Tags
Locate and use manufacturer's engraved metal nameplate for model and serial number information.
Pre-Installation Requirements
Verify mounting surface can bear fan weight and ensure the fan is operated in a level position.
Electrical Disconnects
Ensure disconnects are located near motors for shut-off and locked-out during maintenance.
Moving Parts Safety
All moving parts must have guards; secure fan propeller before maintenance; check for free rotation.
Guards and Protective Devices
Do not operate fans without protective devices; check local codes for compliance.
Inspection Door Operation
Ensure fan propeller has stopped and is secured before opening inspection door; keep door closed.
Inlet Air Pressure and Suction
Fans create suction at the inlet; exercise caution around fans and ensure inlet area is clear of objects.
Fans Rigging and Lifting
Lifting Procedures
Use all lifting brackets, keep fan level, test-lift, and avoid lifting in windy conditions.
Handling and Finish Protection
Rig using brackets or skid; handle to avoid scratching or chipping the coating to prevent corrosion.
Electrical Connections
General Requirements
Supply compatibility, proper fusing, adherence to local/national codes are essential.
Direct Drive Wiring
Route supply internally via provided hole with optional disconnect switch.
Belt Drive Wiring
Route supply internally or connect to disconnect switch/motor directly.
High Temp/Smoke Exhaust Wiring
Keep supply lines out of airstream; may require isolated power for smoke exhaust.
Fusible Link Damper Lifter Safety
Damper Lifter Precautions
Disconnect power, use caution around lifters, they may release dampers unexpectedly.
High Tension Damper Lifter Pinning
Extra heavy duty lifters on specific models must be pinned to prevent accidental tripping during servicing.
Pinning Procedure Illustration
Figures 2A and 2B illustrate safety pin placement for servicing versus in-service states.
Unit Start-Up Procedures

Disconnect and secure all electrical power to the OFF position before any inspection or servicing.
Initial Equipment Verification
Verify equipment matches order and electrical specifications; report discrepancies immediately.
Pre-Start-Up Checklist
Confirm voltage, check piping, rotate propeller, check fasteners, alignment, guarding, and connections.
Initial Start-Up Steps
Check fasteners, propeller rotation, and adjust fan RPM while monitoring motor amperage.
Making Electrical Connections
Ensure supply voltage/phase/amperage compatibility; connect wiring to disconnect switch or motor.
Routine Maintenance and Operation
Pre-Operation Safety
Disconnect and secure all electrical power to the OFF position before any inspection or servicing.
Fan Operation Frequency
Run or 'bump' fans every thirty days to ensure components are up to temperature and grease is redistributed.
Operating Condition Changes
Consult manufacturer before changing operating speed, pressure, or temperature for safe operation.
Motor Maintenance
Limit cleaning to exterior surfaces; lubricate motors with fittings per recommendations; replace grease after 2000 hours.
Fastener Tightness
Periodically inspect and tighten all fasteners and set screws due to normal fan vibration.
Direct Drive Lubrication
Lubricate motors only when fittings are provided; many are permanently lubricated.
Belt Drive Bearings
Inspect bearings, locking collars, and set screws at regular intervals for proper function.
Belt Drive Lubrication
Lubricate bearings semiannually with high-quality grease; use special grease for extreme temperatures.
