Installation Affect of Installation on Performance Inspect the unit for any damage and report it to the shipper immediately. Also, check to see that all accessory items are accounted for. Restricted or unstable flow at the fan inlet can cause pre-rotation of incoming air or uneven loading of the fan wheel, yielding large system losses, increased sound levels and structural failure of the fan wheel. Free discharge or turbulent flow in the discharge ductwork will also result in system effect losses.

R ota tio On belt drive units, centering can be accomplished Wheel Rotation by (a) loosening the inlet cone bolts to move the inlet Rotation direction of the wheel is critical and incorrect cone or by (b) loosening the bearings in order to Backward Inclined rotation These are the original drawings on the Illustrator file will result in reduced air performance, move the shaft. Wheel andwhen inletI opened cone overlap can it.

Blower Maintenance (Belt Drive) Belts tend to stretch after a period of time. They should be periodically checked for tension and wear. When replacing belts, use the same type as supplied with the unit. Replacement of belts should be accomplished by loosening the tensioning “L-Bolts” so the belts may be removed by hand. Do not force belts on or off as this may cause breakage of cords and lead to premature belt failure. Belt tension should be adjusted to allow 1/64 in. of belt deflection per 1 in.
