Pump Motors 23
Level 2 A.O.Smith
■ Check motor windings and capacitor (where
used) for “ground” or “short”.
■ Check terminal board connections with the
motor wiring diagram for proper applied volt-
age.
■ Check the motor start switch and governor to
be sure it is adjusted properly and is opera-
tional.
NOISY OPERATION
■ Check motor coupling, brackets and other
attached parts for adjustment or looseness.
■ Motor bearings.
■ Pump cavitation.
ELECTRICAL SHOCK
■ Check motor windings, all motor wiring, and
capacitor for ground.
PROTECT AGAINST MOISTURE
■ The open drip proof type motors discussed
here may be used outside, but their life
expectancy is enhanced if they are protected
from the elements. The enclosures should not
restrict air flow or cause recirculation.
■ Motors that are out of service, such as pool
motors in the winter, should not be sealed in
plastic bags which cause condensation direct-
ly in the motor.
■ If the motor is not running it may be covered
for short periods of time such as when the
area around a swimming pool pump is being
hosed down.
