SPECIAL WIRING PRECAUTIONS
All installation should be wired according to the following diagrams.
Failure to comply will cause the motor to “hum” or not work.
Maximum torque that can be applied to the terminal block screws is 0.79 Nm (7 lb-in).
TROUBLESHOOTING
If fan fails to operate, please check the following:
a. Consult wiring diagrams included to ensure proper connections.
b. To ensure proper contact, check motor lead wiring, incoming supply
wiring and capacitor connections.
c. If possible, use a meter to test for continuity between fan leads.
Please note capacitor will show no reading if tested with meter.
MAINTENANCE
1. Since fan bearings are sealed and have been provided with an internal
lubricating material, no lubrication is necessary.
2. Once a year, remove any airborne particles in the impeller. No other
maintenance is required.
