Airfoil Blade & Winglet Installation
IMPORTANT: Do not operate fans without the airfoil
blades. Failure to comply with this warning will result
in voiding of the product warranty and may result in
permanent damage to the VFD and motor.
WARNING
To reduce the risk of personal injury, do not bend
motor struts, airfoil blades, or airfoil retaining links
when installing the airfoil blades, balancing the blades,
or cleaning the fan. Damage to these components may
result in unsafe operation of the fan, which can lead
to property damage, personal injury or death. Contact
your local representative or the factory if replacement
parts are needed.
WARNING
To reduce the risk of personal injury, do not insert
foreign objects in between rotating fan blades.
AVERTISSEMENT
Pour réduire le risque de blessure, ne pliez pas les
entretoises moteurs, ailerons ou aile en conservant
des liens lors de l'installation des aubes, équilibrez,
ou nettoyer le ventilateur. Ces composants peuvent
endommager en utilisation dangereuse du ventilateur,
qui peut conduire à des dommages matériels, des
blessures ou la mort. Ces composants peuvent

Components required from Bag # 916400:
• Airfoil Blade (5)
• Winglet (5)
• #10 – 12 x 3/4 in. Screw (10)
• 5/16 in. – 18 Grade 5 Nylon Locknut (10)
• 5/16 in. – 18 x 1-1/4 in. Grade 5 Hex Bolt (10)
Hardware/Tools Needed (Not Included):
• 1/2 in. Socket and Socket Wrench
• 1/2 in. Wrench
• Torque Wrench
• #2 Phillips Bit and Driver
1. Install one winglet per airfoil blade using the screw
bosses located in each blade on the opposite end
from the mounting holes. Use a #2 phillips bit to
install (2) #10 – 12 x 3/4 in. screws per winglet.
Torque screws to 60 in∙lbf (6.8 N∙m).

#10 - 16 x 3/4 in. SCREW
(2 PER BLADE)
2. Lift the first blade into place, and slide over the
motor strut allowing the airfoil retaining ring to rest
on top of the airfoil blade. It might be necessary to
use two people for this step.
3. With the blade in position on the motor strut, install
(2) 5/16 in. - 18 x 1-1/4 in. hex bolts, and (2) 5/16
in. – 18 nylon locknuts as shown below. Hand
tighten hardware.
MOTOR STRUT
5/16 in. - 18 x 1-1/4 in. GRADE 5 HEX BOLT
(2 PER BLADE)
4. Repeat steps 1 through 3 on remaining airfoil
blades. Torque the (10) installed bolts to 20 ft∙lbf
(27.12 N∙m).
IMPORTANT: If airfoils must be removed and
reinstalled for any reason, do not re-use the supplied
nylon locknuts. Re-use increases the risk of locknuts
loosening during operation, which may result in
unwanted noise and/or unsafe operation of the fan.
Contact your local representative or the factory if
replacement parts are needed.
