4. Operation
Before continuing, ensure you have completely read and understood this manual’s
Safety section, in addition to the safety information in the section(s) below.
4.1. Operation Safety
• Keep away from fan impeller/blade; high suction can pull a person toward the inlet. Contact
with an unguarded impeller/blade will cause severe injury.
• Keep inlet screen and safety guards securely in place at all times.
• Ensure the fan inlet is not plugged with any foreign material.
• Do not operate the fan if there is excessive vibration or noise.
• Ensure that electrical cords are in good condition; replace if necessary.
• Ensure maintenance has been performed and is up to date.
4.2. Start-Up and Break-In
Before operating the centrifugal fan, perform a visual inspection, see Section 5. Maintenance on page 27 .
1. Ensure that the fan is properly attached to the grain bin and properly supported. Refer to Section 3. –
Installation on page 19 .
2. Ensure that the fan inlet is not obstructed or restricted in any way.
3. Open the bin roof vents.

5. Single Phase Models: Move the toggle switch to the START position (this is the spring-loaded or momentary
position of the switch).
Æ
6. Three Phase Models: Press the green START button and hold momentarily until fan starts. The fan should
continue to run once green button is released.
7. If the fan does not start or if it stops running, refer to Section 6. – Troubleshooting on page 29 .
8. During the first few minutes of operation, ensure that the unit is running properly and not vibrating
excessively.
Continual use of a vibrating fan will cause premature failure of the motor and bearings. It
will also cause metal fatigue in the fan wheel assembly and fan housing.
9. Bolts and nuts should be rechecked after eight hours and again in two weeks of operation.
4.3. Roof Vents
Roof vents should be sized at 1 ft 2 for every 1000 ft 3 /min of air to minimize condensation.
Roof vents may become partially or fully blocked with ice in temperatures below freezing with high humidity
conditions. Discontinue operation of fan in these conditions or add supplemental heat.
