The number one enemy of a motor is
heat. Overheating always results
whenever there is a lack of clean, continually-circulating
air for a motor. Heat can damage a motor’s windings,
insulation, bearing lubricant and run capacitor. In short,
heat can quickly decrease the service life of a motor.
Remember, proper ventilation is always a crucial consid-
eration when installing a motor.
If at all possible, install a motor in a location that is
free of dirt, dust or airborne debris, such as leaves.
Indoors is best, but not in areas with high humidity,
such as a laundry room or shower area. If the motor is
installed outdoors, try to choose a shady spot that’s pro-
tected from leaves and grass clippings. If you cover the
motor to protect it from possible debris or water, be
sure to leave enough space between the cover and the
motor for adequate ventilation.
A.O. Smith single phase pool and spa motors
feature a thermal overload protector that will shut down
the motor if it overheats. As the windings begin to cool
down, the overload protector will automatically re-start
the motor. Blocked ventilation or an overload condition
can cause the motor to shutdown on a repeated basis.
If a problem cannot be located or if tripping continues
after a noted problem is corrected, contact the original
equipment contractor for a recommendation on
matching motor horsepower to the pump.
TIP: In situations where the ambient temperature is
exceptionally hot, utilizing an E-Plus (High Efficiency)
motor in place of a standard efficient motor can
prevent the overload protector from nuisance tripping.
