ANNUAL PLANNED MAINTENANCE
RUN / TEST
Turn the power disconnect switch on the
control box to the ON position. Allow a few
seconds for the frequency drive to power up.
Turn the Fan Control to the ON position.
Watch the rotation of the fan. The fan should
turn clockwise when you are standing below
the fan looking up. If the rotation is the wrong
direction, disconnect power to the control box
and reverse two of the three wires from the
control box to the motor.
Adjust the fan speed to 30 hz. Count the
number of revolutions the fan makes in
1 minute. They should be approximately the
following:
12’ (2440 mm) Fans = 40 rpm
10’ (3050 mm) Fans = 50 rpm
8’ (3660 mm) Fans = 60 rpm
If the fans do not spin at these speeds, consult
factory for assistance.
