Page 21 of 40 A. STARTING AXIAL FAN 1. 230/460 VOLT FAN On 230 Volt and 460 Volt units, the fan is started by moving the toggle from the “OFF” position through the “RUN” position up to the “START” position. When the fan begins to start the switch should be released. -
Page 22: Maintenance
Page 22 of 40 MAINTENANCE FAN OPERATION IN OFF SEASON During the off season, the fan blade should be allowed to turn freely. Also, during the off season, OPERATE THE FAN FOR APPROXIMATELY 30 MINUTES EVERY THREE WEEKS. The operation of the fan keeps the lubricant more evenly distributed within the bearing cavity and dries out any condensation that could be in the motor. -

Page 31: Troubleshooting
Page 31 of 40 7. The contactor for the 460 volt control is then reinstalled into the control enclosure, and the toggle switch wires and the motor thermal protections wired per Figure 19 on Page 26. 8. Connect the motor leads to the output terminal of the contactor per the illustration in Figure 23. - Page 32 Page 32 of 40 Check holding coil. (If coil is defective, replace) a. Make sure there is power from L2 on the contactor to the holding coil. b. Make sure there is power going from L1 through the motor thermostat wires and the toggle switch. If power is available at the coil, the coil is defective.
- Page 33 Page 33 of 40 E. SYMPTOM: The fan starts and operates for a while and then shuts off. Check the supply voltage. Voltage should be within 10% of rated voltage. For example, a motor rated at 230 Volt should operate in a voltage range of 207 to 253 Volts.
