Vane Axial Fan
6. Fan Operation
After initial installation and also prior to using the unit each season, check the operation to ensure proper
functioning, adjustment, and reliability.
Fan Start-up
1. Make certain the unit is properly installed and connected, as described within the installation section
of this manual. All air passage joints and seams must be well sealed.
2. With main power supply turned OFF, rotate the blade by hand to make certain it turns freely without
contacting the housing or venturi.
3. Open roof doors to allow airflow at all times when fan is operating.
IMPORTANT: Refer to roof damage disclaimer in the safety section
of this manual.
4. Turn ON main power disconnect switch.
5. Press the fan START button and check the following:
a. Check direction of blade rotation. Correct if needed by following the instructions on the motor.
b. Check to make sure the blade comes to full operating speed in less than 10 seconds. If there
is any doubt as to proper operation, check the current draw of the motor. The motor amperage
should not exceed the maximum full load amps listed on the motor nameplate.
Fan Shut Down
1. Press the fan STOP button on units equipped with motor controls.
2. Shut off electrical power at main and at disconnect.
3. Close the roof openings and cover fan inlet to prevent harmful back-draft air currents from passing
through the grain and to avoid grain infestation from rodents and insects.
Maintaining Grain Quality
To properly maintain the quality of stored grain, it is necessary to keep the grain dry, cool and insect free.
Any one of these problems can contribute to spoilage. Wet, warm grain promotes insect growth as well
as grain spoilage. Cool, dry grain can keep for long periods of time.
It is recommended that the grain be kept cool (avoid freezing as freezing can reduce quality). Grain
should be cooled through the fall and winter, warmed in the spring and summer.
Make certain all guards and covers are securely in place.
