Troubleshooting

If fan fails to operate, please check the following:
1. Consult wiring diagrams (page four of these instructions) to insure proper connection.
2. Check motor lead wiring, capacitor leads and incoming supply leads to insure definite contact.
3. If possible, use a meter to test for continuity across the fan motor leads. In order to do this, the capacitor must be disconnected (do not test the
capacitor it will not meter continuity). If motor leads show continuity, consult manufacturer for a replacement capacitor.

Maintenance

1. Since fan bearings are sealed and provided with an internal lubricating material, no additional lubrication is necessary.
2. When using in a dryer boosting application, DISCONNECT POWER SUPPLY and check impeller periodically for lint buildup.
No other maintenance is necessary.
