INLINE DUCT BLOWERS
OPERATION
1. Complete the electrical connections, energize the unit momentarily and ensure proper wheel rotation. (see Fig, 1).
2. Apply full power.
3. With all ducts attached, the access doors in place and the air system in full operation, measure the motor current and ensure that it is
less than the rated full load motor amperage as indicated on the motor nameplate.
MAINTENANCE
WARNING
ENSURE POWER SUPPLY IS DISCONNECTED & LOCKED OUT PRIOR TO MAKING ELECTRICAL CONNECTIONS.
1. Inspect and tighten all bearing collar and wheel set screws after the first 50 to 100 hours of operation and periodically thereafter.
2. Follow motor manufacturer's instructions for motor lubrication. Remove any excess lubrication.
3. Check the drives.
a. Tighten set screws on pulleys, wheel and bearing locking collars.
b. Check belt tension and alignment.
c. Replace cracked or worn belts.
4. Blower bearings are permanently lubricated and require no further lubrication.
5. Inspect V-belts for wear and proper tension. If it is necessary to replace one belt on a multiple belt drive, replace all the belts with a
matched set. Do not use belt dressing.
6. Clean the blower wheel periodically. Material build up on the blades can cause wheel imbalance which may result in wheel or bearing
failure.
7. To reinstall replacement ball bearings press the locking collar against the inner ring of the bearing and turn in the direction of the shaft
rotation until engaged. Insert a drift pin into the pin hole and tap lightly to set. Tighten set screw on locking collar firmly (see Fig. 7 ).
8. Should further service to the blower be necessary, refer to the exploded view illustrations (see Fig. 8 or 9).
