Before starting the blower for the first time under
power, recheck the installation thoroughly to
reduce the likelihood of difficulties. Use the
following checklist as a guide, but consider any
other special conditions in your installation.
1. Be certain no bolts, rags, or dirt have been left
in the blower.
2. Be certain that inlet piping is free of debris. If
an open outdoor air intake is used, be sure the
opening is clean and protected by an inlet filter.
This also applies to indoor use.
3. If installation is not recent, check blower
leveling, drive alignment, belt tension, and
tightness of all mounting bolts.
4. Be certain the proper volume of oil is in the oil
reservoir chambers.
5. Be certain the driving motor is properly
lubricated and connected through suitable
electrical overload devices.
6. With electrical power off and locked out to
prevent accidental starting, rotate the blower
shaft several times by hand to make sure the
blower is rotating freely. Unevenness or tight
spots are indicators of a condition that should
be corrected before progressing.
7. Check motor rotation by momentarily pushing
the START button and then checking the flow
direction of the blower. Reverse the motor
connections if the flow is in the wrong direction.
Carry out initial operation under “no load”
conditions by opening all valves and venting the
discharge to atmosphere, if possible. Then, start
the motor briefly, 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 first 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 first opportunity, stop
the blower and clean or remove the inlet filter.
Also recheck leveling, coupling alignment or belt
tension, and mounting bolts for tightness.
RECOMMENDED SHUTDOWN
PROCEDURE TO MINIMIZE RISK OF
FREEZING OR CORROSION
When a blower is taken out of service, it may
require internal protection against rusting or
corrosion. The need for such protection must be
a matter of judgment based on existing conditions
as well as length of down time. Under atmospheric
conditions producing rapid corrosion, the blower
should be protected immediately. When an air
piping system has high humidity or moisture,
water condensation can occur after the blower is
shut down and it begins to cool. Condensation
creates an environment favorable to corrosion of
