1. With inlet guard not installed, spin the blade assembly by hand and make sure that the blade
assembly rotates freely and did not shift during shipment. If the blades rub in the fan housing, refer
to Page 8 for instructions on centering the blade assembly.
2. Check belt for proper tension.
3. Check motor pulley, driven disc and idler pulley (if present) for proper alignment.
4. Check to make sure all fasteners are properly tightened.
5. Check circuit phase, voltage and wiring connection against that shown on motor nameplate.
6. Check for correct fan rotation.
7. Replace the inlet guard. The fan is now ready for proper operation.
INITIAL STARTUP
MAINTENANCE
CLEANING
x
The fan should be cleaned regularly. Always turn the fan off and disconnect the power connection before
cleaning.
x
The motor should be wiped with a cloth or a brush. This will keep the motor running cool.
DO NOT
pressure
wash the motor.
x
The blades should be wiped clean to maintain maximum air performance and minimize fan imbalance.
DO
NOT
pressure wash the center of the disc assembly, or premature bearing failure may be induced.
x
The damper door assembly should be wiped clean so that the doors will pivot freely, open completely, and
close securely.
x
The interior sides of the fan, wall housing & doors, should be washed properly after disinfecting the house to
prevent rusting. We recommend using Simple Green detergent or a similar product.
CHECK FASTENERS
Inspect all fasteners on the fan. This is a very important safety issue. If any loose hardware is found, tighten it
immediately.
CHECK BELT TENSION
The belt must have proper tension to insure proper fan speed and maximum air performance. Refer to Page 9 if re-
tensioning is necessary.
CHECK DRIVE ALIGNMENT
The belt must be properly aligned in the pulleys to minimize pulley and belt wear. Refer to Page 8 for instructions.
CHECK DOOR-RING GASKET
The door-ring is lined with a foam rubber gasket material. This gasket provides a seal between the door-ring and
the doors, insuring proper door function and minimizing air leakage. This gasket should be checked periodically to
make sure it is intact and properly sealed to the door-ring. If the material should come loose from the door-ring, it
must be re-sealed to the door-ring with appropriate adhesive.
