After initial installation and also prior to using the unit
each season, check the operation to ensure proper
functioning, adjustment, and reliability.
FAN OPERATION
1. Make certain that unit is properly installed and con-
nected, as described within the installation instructions.
All air passage joints and seams must be well-sealed.
2. With main power supply turned OFF, rotate the wheel
by hand to make certain it turns freely without contact-
ing the housing or inlet cone.
3. Open roof doors to allow airflow at all times when fan
is operating.
CAUTION: Fan pressures can overload bin roof or
walls causing structural damage or collapse. Bin
must be adequately ventilated and fans and screens
free of obstructions. Do not run fans if icing can occur
on screens.
4. Turn ON main power disconnect switch.
CAUTION:
Make certain all guards and covers are
securely in place.
5. Press the fan START button and check the following:
A. Check direction of wheel rotation. THIS IS A VERY
IMPORTANT CHECK ON INITIAL START-UP OF 3-
PHASE MODELS. The wheel must rotate clockwise
when viewed through the inlet guard.
NOTE: 3-Phase motors may be reversed by inter-
changing any two power leads.
B. Check to make sure the wheel comes to full operat-
ing 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 within Tables 1 and 2 or
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.
