Airfoil Blade & Winglet Installation - Greenheck DS-M Installation, Operation And Maintenance Manual

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.
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.
Components required from Bag # 915066:
• Airfoil Blade (3 OR 6)
• Winglet (3 OR 6)
• #10 – 12 x 3/4 in. Screw (6 OR 12)

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).

blades. Torque the installed bolts to 25 ft∙lbf
(34 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
