Fan Maintenance

DANGER
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.
NOTE: Installation and maintenance are to be
performed only by qualified personnel who are familiar
with local codes and regulations and have experience
with this type of equipment.
Once the fan has been put into operation, a periodic
maintenance program should be set up to ensure
reliable fan performance. A proper maintenance
program will help deliver years of dependable service.
Items to be included in this program are as follows:
1. Verify that all fasteners are tight and properly
torqued.
2. Verify that all of the fan's safety systems (safety
cable, hub retaining bracket) are properly installed.
Inspect for signs of damage or failure.

Each fan bears a manufacturer's nameplate with the
fan's model number and a unique serial number for
identification. This information will assist the local
representative and the manufacturer in providing service
and replacement parts.
IMPORTANT: Do not remove VFD enclosure or VFD
circuit board from motor/hub assembly under any
circumstances. Removal of the VFD or VFD circuit board
will result in voiding of the fan warranty.

3. Inspect the fan for signs of fatigue, corrosion, or
wear.
4. Impellers require little attention when moving clean
air. Occasionally, oil and dust may accumulate
causing imbalance. When this occurs, clean
the impeller and other fan components to
ensure smooth and safe operation. Remove any
accumulated dust and dirt using hot water or mild
cleaning solutions. Harsh chemicals should not
be used to clean the fan as they may damage the
fan's finish or motor.
IMPORTANT: Do not allow water or solvents to enter
the motor. Under no circumstances should motors be
sprayed with steam, water or solvents.
5. Motor maintenance is generally limited to cleaning.
Limit cleaning to exterior surfaces only. Removing
dust buildup on motor housing ensures proper
motor cooling.
6. Prior to restarting unit, check all fasteners for
tightness each time maintenance checks are
performed.

Fan Balancing (Optional)

Required Components from Bag # 918439:
• Clip-on Balance Weights (8)
• Permanent Balance Weights (8)
1. If unbalance or swaying are observed during fan
operation, add the (4) supplied clip-on weights to
one airfoil blade. Turn the fan on and observe fan
operation. Take note if fan balance is improved.
2.
Move the (4) clip-on weights to each
blade and repeat step 1 to determine which blade
requires permanent balancing weights to be applied.
3. Once the ideal blade is identified, move the clip-on
weights from the blade tip towards the motor hub
to identify the appropriate location for weights to
be applied. Test fan operation at multiple locations
until best operation is observed.
4. After identifying the appropriate location and
quantity of weights to apply, replace the clip-on
weights with permanent weights using the same
quantity and location.
