RECEIVING & START-UP
Receiving Inspection
When unit is received, inspect immediately for damaged or missing parts. Even though
all units are carefully inspected and prepared for shipment at the factory, rough handling
enroute may cause concealed damage or cause nuts, bolts or locking collars to work loose.
Check propeller to see that it rotates freely and that there are no obstructions. Be certain all
bolts and locking collars are tightened securely.
If concealed damage is found, call the carrier and ask for their Inspection
Department. Then fill out a concealed damage inspection report.
Handling:
Handle your equipment with care. Some fans are provided 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.
DO NOT LIFT AXIAL FANS BY THE MOTOR, MOTOR BASE OR PROPELLER. Axial fans
should be lifted by using straps around the fan housing.
DO NOT LIFT ROOF VENTILATORS BY THE STACK CAP OR HOOD. Roof ventilators
should be lifted by using straps around the fan housing or base only. Spreader bars should also
be used to avoid damage to stack caps or hoods.
Installation:
Fans should always be mounted to a flat, level and rigid structure. Shim the fan where
necessary. This will ensure permanent alignment and a smooth running, vibration free fan, as
well as minimize maintenance costs.
Poured concrete foundations are recommended, wherever practical, for floor mounted fans.
Fans mounted off ground level should be rigidly mounted to a structural platform and be placed
as near as possible to or over, a solid wall or column.
Supports for suspended fans must be crossbraced for live load support to prevent side sway.
