MOTOR WIRING CONT. / 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.
Adjust the fan speed to 60 Hz. Count the
number of revolutions the fan makes in
1 minute. They should be approximately the
following:
12' (2440 mm) Fans = 80 rpm
10' (3050 mm) Fans = 100 rpm
8' (4880 mm) Fans = 130 rpm
If the fans do not spin at these speeds, consult
factory for assistance.
FORWARD / REVERSE
The Rave ® Fan is the most efficient running in
the forward direction (blowing air downward).
For some installations where it is not desirable
to move the air downward, or you do not want to
feel as much air movement, the fan can be run
in reverse.
