Receiving and Inspection
Carefully inspect the fan and accessories for any dam-
age and shortage immediately upon receipt of the fan.
• Turn the prop by hand to ensure it turns freely and
does not bind.
• Record on the Delivery Receipt any visible sign of
damage.
Handling
Handle your equipment with care. Some fans are pro-
vided with lifting lugs or holes for easy handling. Others
must be handled using nylon straps or well-padded
chains and cables which protect the fan’s coating and
housing. Spreader bars should be used when lifting large
parts.
Axial fans should be lifted by using straps around the
fan housing only. DO NOT LIFT AXIAL FANS BY THE
MOTOR, MOTOR BASE, PROP OR FLANGES.
Storage
If the fan is stored for any length of time prior to instal-
lation, completely fill the bearings with grease or mois-
ture-inhibiting oil. Refer to Lubricants on page 6. Also,
store the fan in its original crate and protect it from dust,
debris and the weather.
WARNING
This unit has rotating parts. Safety precautions
should be exercised at all times during installation,
operation, and maintenance.
ALWAYS disconnect power prior to working on
VAD
Outdoor Storage
To maintain good working condition of a Vane Axial when
it is stored outdoors, or on a construction site, follow the
additional steps below.
• Cover the inlet and outlet, and belt tunnel opening to
prevent the accumulation of dirt and moisture in the
housing.
• Periodically rotate the prop and operate dampers (if
supplied) to keep a coating of grease on all internal
bearing parts.
• Periodically inspect the unit to prevent damaging condi-
tions.
Installation
To prevent damage to the fan during shipping, motors 25
HP and larger, and extremely heavy motors (cast iron or
severe duty) are shipped loose and must be field mounted
by bolting the motor on the motor mounting plate in the
existing mounting slots.
Personal Safety
Disconnect switches are recommended. Place the
disconnect switch near the fan in order that the
power can be swiftly cut off in case of an emergency,
and in order that maintenance personnel are
provided complete control of the power source.
