6. MAINTENANCE AND TROUBLESHOOTING
6.1 CLEANING INTERVALS
The BEF ventilator is designed for prolonged use. It must be
inspected and cleaned at least every 12 months. The need
for cleaning is dependent on application type and ventilator
operation. In dryer applications, periodic cleaning is required
and during the first couple months the ventilator should be
inspected every two weeks to determine lint build up rate. If
lint accumulates, it must be removed to prevent a lint fire and
to ensure efficient operation of the dryers.
6.2 CLEANING
Deposits should be removed from the impellers and the
bottom of the ventilator:
1. Turn fan off at the repair switch.
2. When ventilator wheel no longer rotates, open access
door.
3. Clean inside housing and wheel with suitable water
detergent solution.
4. Dry all parts thoroughly with cloth.
5. Close and secure access door.
6. Turn ventilator on.
Vibrations can be caused by a dirty impeller. If necessary,
the impeller wheel can be removed. Prior to removal, mark
the impeller position on the shaft. Do not remove balancing
weight(s) on the impellers. No other maintenance is required.
6.3 SERVICE
Available spare parts are shown in Section 6.4 Replacement
Parts Ordering.
The motor has sealed and permanently lubricated bearings.
Bearing replacement should only be done by ENERVEX or an
authorized motor repair shop.
