REVISIONES ANTES DE COMENZAR

1. Disconnect and lock-out all power switches to fan. See warning below.
2. Check all fasteners, set screws and locking collars on the fan, bearings, drive, motor base and
accessories for tightness.
3. Rotate the fan wheel by hand and assure no parts are rubbing.
4. Check for bearing alignment and lubrication.
5. Check the V-belt drive for proper alignment and tension.
6. Check the all guarding (if supplied) for being securely attached and not interfering with rotating parts.
7. Check operation of variable inlet vanes or discharge dampers (if supplied) for freedom of movement.
8. Check all electrical connections for proper attachment.
9. Check housing and ductwork, if accessible, for obstructions and foreign material that may damage
the fan wheel.
PASOS ADICIONALES PARA LAS REVISIONES ANTES DE COMENZAR
1. Check for proper wheel rotation by momentarily energizing the fan. Rotation is always determined by viewing the wheel from
the drive side and should correspond to the rotation decal affixed to the unit. One of the most frequently encountered
problems with Centrifugal Fans is motors which are wired to run in the wrong direction. This is especially true with 3-phase
installations where the motor will run in either direction, depending on how it has been wired. To reverse rotation of a 3-
phase motor, interchange any two of the three electrical leads. Single phase motors can be reversed by changing internal
connections as described on the motor label or wiring diagram.

2. If the fan has inlet vanes, they should be partially closed to reduce power requirements. This is especially important if the fan
is designed for a high temperature application and is being started at room temperature.
3. Fans with multi-speed motors should be checked on low speed during initial start-up.
4. Check for unusual noise, vibration or overheating of bearings. Refer to the "Troubleshooting" section of this manual if a
problem develops.
5. Grease may be forced out of the bearing seals during initial start-up. This is a normal self-purging feature of this type of
bearing.
