Operation
7. Check motor rotation by momentarily pushing
the START button and then checking the
À
ow
direction of the blower. Reverse the motor
connections if the
À
ow is in the wrong direction.
Carry out initial operation under “no load”
conditions by opening all valves and venting the
discharge to the atmosphere, if possible. Then,
start the motor brie
À
y, listen for unusual noises,
and make sure the blower coasts freely to a stop.
If no problem appears, repeat this check and let
the motor run slightly longer. If any questions exist,
investigate before proceeding.
Assuming all tests are satisfactory, the blower will
now be ready for continuous full-load operation.
During the
¿
rst several days, check periodically to
make sure all conditions remain acceptable and
steady. These checks may be particularly important
if the blower is part of a process system where
conditions may vary. At the
¿
rst opportunity, stop
the blower and clean or remove the inlet
¿
lter.
Also recheck leveling, coupling alignment or belt
tension, and mounting bolts for tightness.
